[FFmpeg-user] MXF Op1a with JPEG2000 - Field Order Problem (Frame Layout and Field Dominance)
Hello FFmpeg Developers! I am currently trying to produce a interoperable MXF OP1a with JPEG2000+PCM. The content is interlaced material in PAL (tff), including VBI (720x608) My used syntax: ffmpeg -i J:\JPEG2000\8bit_10min_01_ffvhuff.avi -c:v libopenjpeg -acodec pcm_s24le -f mxf -timecode 10:00:00:00 -metadata "creation_time=2022-12-18T15:37:56" -r 25 -signal_standard 1 -colorspace bt470bg -color_range tv -color_primaries bt470bg -color_trc gamma28 -aspect 4:3 -vf "setfield=tff,fieldorder=tff" -top 1 -format:v j2k -profile:v jpeg2000 -cinema_mode:v off -irreversible:v 0 -prog_order 0 J:\JPEG2000\8bit_10min_01_ffvhuff.mxf As you can see, I am setting the field oredr twice via "-top 1" and "-fieldorder=tff". So I assume that I will get a MXF with interlaced flags: Typical: signal_standard : ITU_601 (value='1') frame_layout: Separate Field (value='1') Field Dominance : 1 But I get signal_standard : ITU_601 (value='1') frame_layout: Full_Frame (value='0') Field Dominance : not set Checked via mxf2raw and mxfdump from the BMX MXF toolset. I also tried to reset the frame_layout via bmxtranswrap but it sticked to FULLFRAME. I dont know why. My questions: 1.) Is it possible to give the ffmpeg MUXER more settings beside -f mxf and -signal_standard 1 so that I have more control to set specific flags/KLVs? 2.) Due frame_layout is not set to seperate fields by using "-top 1" or "fieldorder=tff" Is there room for improvement? br Christoph output of mxf2raw: edit_rate : 25/1 duration: 00:10:00:00 (count='15000') StartTimecodes: material: 10:00:00:00 file_source : 10:00:00:00 Tracks: (2) Track #0: essence_kind: Picture essence_type: JPEG2000_CDCI ec_label: urn:smpte:ul:060e2b34.04010107.0d010301.020c0100 edit_rate : 25/1 duration: 00:10:00:00 (count='15000') Packages: (1) Package #0: Material: package_uid : urn:smpte:umid:060a2b34.01010105.01010d00.13c54e3f.52947134.9ec54e3f.00529471.349ec500 track_id: 2 track_number: 0 FileSource: package_uid : urn:smpte:umid:060a2b34.01010105.01010d00.13c54e3f.52947134.9ec54e3f.00529471.349ec501 track_id: 2 track_number: 0x15010800 file_uri: file:///J:/JPEG2000/8bit_10min_01_ffvhuff.mxf PictureDescriptor: coding_label: urn:smpte:ul:060e2b34.04010107.04010202.03010100 signal_standard : ITU_601 (value='1') frame_layout: Full_Frame (value='0') stored_width: 720 stored_height : 608 display_width : 720 display_height : 576 display_x_offset : 0 display_y_offset : 32 aspect_ratio: 4/3 CDCIDescriptor: component_depth : 8 horiz_subsamp : 2 vert_subsamp: 1 color_siting: Cositing (value='0') Track #1: essence_kind: Sound essence_type: WAVE_PCM ec_label: urn:smpte:ul:060e2b34.04010101.0d010301.02060300 edit_rate : 25/1 duration: 00:10:00:00 (count='15000') Packages: (1) Package #0: Material: package_uid : urn:smpte:umid:060a2b34.01010105.01010d00.13c54e3f.52947134.9ec54e3f.00529471.349ec500 track_id: 3 track_number: 0 FileSource: package_uid : urn:smpte:umid:060a2b34.01010105.01010d00.13c54e3f.52947134.9ec54e3f.00529471.349ec501 track_id: 3 track_number: 0x16010300 file_uri: file:///J:/JPEG2000/8bit_10min_01_ffvhuff.mxf SoundDescriptor: sampling_rate: 48000/1 bits_per_sample : 24 block_align : 24 channel_count: 8 locked : true Output of mxfdump : [ K = MXFCDCIEssenceDescriptor ( 13cf ) 06.0e.2b.34.02.53.01.01.0d.01.01.01.01.01.28.00, L =321 (141), LL = 4 ] [ k = InstanceUID 3c.0a, l =16 (0010) ] 0 ad ab 44 24 2f 25 4d c7 92 ff 29 bd 00 0e 00 00 ..D$/%M...).

Re: [FFmpeg-user] Matroska Muxer Options documentation
ffmpeg -h muxer=matroska This reveals a bit more options than outlined on the url you mentioned. Sorry, I have already tried that but I forgot to write it here. If you see the matroska.org page there is a ton of flags or values a MKV can carry... But ffmpeg does not show this in the help text how to control this by syntax options. So maybe ffmpeg is not ready for meeting these specs or its just hidden until the spec is finished (v4)? br Chris ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Hello the ffmpeg MKV documentation at "https://ffmpeg.org/ffmpeg-all.html#matroska; is quite short and focussed on stereoscopic content. Is there a more detailed documentation variant for the Matroska muxer that can be used to fully utilize the current options for MKV muxing? At matroska.org there is the specification to read but no ffmpeg syntax examples how to generate such MKVs (or I did not find it yet there). Could someone give me a tip here?

[FFmpeg-user] XDCAMHD422 MXF files - MXF IndexTableSegments have the same InstanceUIDs (not unique)
Hello everyone! I am currently testing with XDCAMHD422 mxfs generated by ffmpeg 4.4 and 5.0. I am testing these MXFs against the SMPTE ST377 Standard. My testtool is the MXF Analyser from the IRT which can test the MXF against Standard Compliance SMPTE ST377 MXF. The MXF files generated by FFMPEG are almost "green" to ST377 but one single issue comes up all 10 seconds in the file: "This Index Table Segment has the same Instance ID value of ad.ab.44.24.2f.25.4d.c7.92.ff.29.bd.00.0f.00.00 as the Index Table Segment located at byte offset 78605312. The current Index Table Segment is not a repetition of the earlier Index Table Segment" Which means: Each Index Table Segment in an SMPTE ST377 conform MXF file should have its unique InstanceUID. And the file does not have IndexTableSegments with different UIDs. Currently in the mxf file every InstanceUID of the Index Table Segments have the same values: ad.ab.44.24.2f.25.4d.c7.92.ff.29.bd.00.0f.00.00 ad.ab.44.24.2f.25.4d.c7.92.ff.29.bd.00.0f.00.00 ad.ab.44.24.2f.25.4d.c7.92.ff.29.bd.00.0f.00.00 ... ___ I tested agains other transcoder tools or formats and checked with MXFDUMP tool from the BMX MXF tools: Adobe Premiere XDCMAHD422 Instance UIDs: eb.b1.86.ed.a3.6f.11.ec.b0.7d.48.0f.cf.54.96.c3 f0.8c.82.10.a3.6f.11.ec.86.e9.48.0f.cf.54.96.c3 aa.68.e1.45.a3.6f.11.ec.bd.95.48.0f.cf.54.96.c3 Premiere AVCINTRA Instance UIDs: 3 IndexTableSegments at the end of the file. af.3d.99.3f.a3.9f.11.ec.b6.c7.48.0f.cf.54.96.c3 67.12.9a.70.a3.a0.11.ec.a3.5d.48.0f.cf.54.96.c3 45.3b.ec.c1.a3.a1.11.ec.82.9d.48.0f.cf.54.96.c3 FFMPEG AVCINTRA: just ONE IndexTableSegment InstanceUID: ad.ab.44.24.2f.25.4d.c7.92.ff.29.bd.00.0f.00.00 -> No problem with double UIDs. And FFMPEGs D10 and DVCPRO50 MXFs have only ONE IndexTableSegment -> No problem with double UIDs. Back to the XDCMAHD422File: Via the DEBUG LOG I found out that FFMPEG writes every 252 Frames (10seconds and 2 frames) a new essence container/a new Index Table Segment. You can see that in the attached debug syntax at the bottom of this message (very long). My questions: 1.) Is it possible to control via syntax to write only ONE IndexTableSegment (Essence Container) into a MXF file? And does this make sence for XDCAMHD422 mxfs (GOP based video, GOP=12)? 2.) OR is it possible to fix the issue in a way that IF more than ONE Index Table Segments are written, then every Index Table Segment has a unique Instance UID to be SMPTE ST377 standard conform? 3.)

I use that as historical information metadata for long term archiving. The KLV flag I am talking about is: 3c.08 Platform (MXF Identification) A typical MXF Dump extract of this KLV would look like: [ k = Platform 3c.08, l =12 (000c) ] 0 00 77 00 69 00 6e 00 33 00 32 00 00.w.i.n.3.2.. or [ k = Platform 3c.08, l =66 (0042) ] 0 00 4c 00 69 00 6e 00 75 00 78 00 20 00 32 00 2e.L.i.n.u.x. .2.. 10 00 36 00 2e 00 31 00 38 00 2d 00 33 00 34 00 38 .6...1.8.-.3.4.8 20 00 2e 00 31 00 36 00 2e 00 31 00 2e 00 65 00 6c ...1.6...1...e.l 30 00 35 00 20 00 78 00 38 00 36 00 5f 00 36 00 34.5. .x.8.6._.6.4 40 00 00 I know that the ffmpeg community does not recommend to write such data due security reasons. But I am a user which can live and need that FLAG (for archiving reasons) and I it would be awesome to have just the OPTION to write it -> -> Is there a syntax to force writing this KLV flag like "-metadata platform=win32"? Or something else I can use? -> If there is no syntax to write it, would it be possible to add it in the ffmpeg code so that the user has to turn it ON for force the writing (true/false, 1/0 option)? br Christoph ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
Re: [FFmpeg-user] HD MXF SMPTE ST377 Standard Compliance Problem with multiple IndexTableSegments carring Unique ID twins (maybe a bug)
Hello Carl, thanks for the fast reply Please test current FFmpeg git head, nothing else is supported here. [...] I cant because I am not able to compile. I am just a user. Not a programmer/compiler. I am dependent on the windows exe builds from https://ffmpeg.zeranoe.com/builds/ which are linked on the offical ffmpeg homepage. Is there another way to get a working exe from the current FFmpeg git head? After generating these files I am testing them with an MXF Analyzer which analyses the MXF to SMPTE ST377-1 Standard-Compliance (MXF— File Format Specification). So I check if the MXF is fullfilling minimum MXF requirements for the MXF world. And I get every time the same errors multiple times: How can I reproduce this? How can I see the error messages? Unfortunately you cant without the IRT MXF Analyzer. It is a commercial product from the Institut für Rundfunktechnik. But you can send me your generated files and I can check them and send you a report file back. Regarding mxfdump: You can use the free toolset of BMX MXF from the BBC.

[FFmpeg-user] Upscaling SD 4x3 to FullHD 16x9 - Aspect Ratio problem
Hello I am trying to upscale a 720x608 (incl VBI) 25i 4:3 source to 1920x1080 25i 16:9. My deinterlacing and reinterlacing is working, scaling and cropping too. But I have understanding problem how to use the videofilter regarding aspect ratios. My source is 4:3 and the target is 16:9.

[FFmpeg-user] New Overread VUI by 5 bits Warnings when decoding from AVC-Intra from Avid
Hello, in the year 2014 I reported a Problem when decoding H264 10bit from AVCIntra MXF files. MXF File was created by Premiere: The old thread: https://lists.ffmpeg.org/pipermail/ffmpeg-user/2014-May/021213.html The problem was that the commandline output showed multiple error warnings with this information: "Overread VUI by 5 bits". This problem was fixed in 2014. I think it was a demuxer problem. Now I have the "same" problem with a MXF file from another encoder: AVID. -> Again "Overread VUI by 5 bits" By testing with FFMPEG 3.4 we get this: # May__2014: Decoding AVCIntra MXF made by Premiere: STILL GOOD.

[FFmpeg-user] Increase DVCPRO50 encoding quality possible?
Hello everyone, I am testing the DVCPRO encoder of ffmpeg and comparing it with other tools in terms of picture quality. I mentioned that the picture quality of an ffmpeg dvcpro50 encoding is a little bit less than a dvcpro50 encoding from a carbon coder. In numbers I can say: Original Source Quality = 100 % Carbon Coder Quality = 95% FFmpeg Quality = 90% Regarding encoding speed ffmpeg dvcpro50 encoder wins: 720x576 RAW source to DVCPRO50: ffmpeg: 10x faster than realtime carbon coder: 3x faster than Realtime The FFmpeg sample has more visible blocking artefacts and mosquito noise (can only be seen in zoom mode 400% or more). You can see it here: https://www.dropbox.com/s/lj4lq1kfr8f5c1i/ffmpegusers_dvcpro50.zip?dl=0 I encoded a part of a animation movie to dvcpro50. At smooth color gradients you can see the differences. Stronger mosquito noise and more blocks in the leafs. My used syntax: ffmpeg -i inputfile -vcodec dvvideo -pix_fmt yuv422p outpufile.mxf My question: Is there any syntax option which I can use to increase the DVCPRO50 encoding quality a little bit?

Re: [FFmpeg-user] FFmpeg XDCAMHD422 streamcopy ClosedGOP problem
Hello Carl, good hint. But I have made some tests. And this raises another question: A conventional Start of an XDCAMHD422 file has this GOP structure (closed): B.B.I.B.B.P.B.B.P.B.B.P.B.B.I.. After FFMpeg has cut out a clip, because FFmpeg always cuts at I_frames (doesn matter which -ss position I give, it always cuts at the nearest I_frame): I.B.B.P.B.B.P.B.B.P.B.B.I.. Is it possible to force FFmpeg to cut 2 frames BEFORE an I-Frame (streamcopy)? To get a cutout file with the first GOP structure like this: B.B.I.B.B.P.B.B.P.B.B.P.B.B.I.. Is there a syntax to do so?

[FFmpeg-user] FFmpeg XDCAMHD422 streamcopy ClosedGOP problem
Hello
I want to extract a short clip from a long XDCAMHD422 MXF file via
streamcopy ("lossless").
FFMpeg does this by grabbing the next good I-Frame near the -ss position
in this GOP=12 videostream.
But the problem is:
XDCAMHD422 MPEG2-LongGOP Files always begin with one CLOSED GOP, after
that there are OPEN GOPS.
So the extracted clip (which I want to extract as lossless as possible
via streamcopy) must lead into a new MXF file which starts with one
CLOSED GOP and keep the rest of the original open GOPs.
Because, if the new MXF file starts with an OPEN GOP, then typical
editing programs and also players cannot show frame 1 and 2 when
playing/editing them. Because -> The I frame references to the previous
2 B-Frames (typical for open GOP) which are not present anymore in the
new file.
FFMpeg extracts just OPEN GOPs as is yeah that IS streamcopy.
So my need is to force FFMpeg to make an extraction via codec copy (copy
video and audiostreams) , BUT JUST ENCODE the first GOP to a new CLOSED GOP.
So the first gop of the extracted clip will be renencoded.
Professional XDCAMHD cutting applications are working like that.
The always encoded the first GOP new, and keep the rest of the stream to
keep original quality.
So, is there a possibility to do that with FFMpeg?
Best Regards
Christoph

[FFmpeg-user] Is it possible to set a "this is a dolby E stream" flag to specific Audio Streams in a IMX D-10 MXF File?
Hi I am using FFmpeg for generating a D-10 file with 8ch audio (16bit). Typicall the Audio is always PCM but sometimes some dualchannels are is a Dolby-E pair. Is it possible to set a metadata flag for Audio channels to give the decoder which opens the final MXF the information that it should decode Dolby E and not PCM on e.g Ch5 and Ch6? Example D10 file with Dolby E is 1 stream video (0:0) 1 stream audio with 8ch (0:1): ch1 PCM ch2 PCM ch3 PCM ch4 PCM ch5 Dolby E (encoded as PCM), needs a "Dolby E"-flag ch6 Dolby E (encoded as PCM), needs a "Dolby E"-flag ch7 PCM ch8 PCM Any hints and tipps are welcome :) br Christoph ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
Re: [FFmpeg-user] -vf Colorspace filter - 'Unknown input primaries 2' error
Hi, Kieran, are the DPX logarithmic RGB or linear RGB? In my esperience without using a 3DLUT -> The logarithmic scale of the RGB values always lead to washed out pictures, when transcoding to a linear scale. I think you need a 3DLUT (e.g CineonLOG) and the colorspace filter to get better colors, because your DPXes are logarithmic. If not, then you dont have to care for my posting :) This video also shows very good was a LUT does with logarithmic videos: http://store.pixelfilmstudios.com/plugin/fcpx-lut-loader Best Regards Christoph Am 13.05.2016 um 12:46 schrieb Kieran O'Leary: Hello, I want to transcode a DCP to ProRes or x264 while transforming to bt709.

Dave Rice Hell Dave, thank you for the hint. I am testing now different videos with QC tools (based on ffmpeg) and using the integrated Y filter to show a graph on the timeline. That works good. Looks like in Davinci Resolve scene cut filter :) And the peaks in the timeline hit hardly all hard cuts. Some false positives when flashing happens in video, but this does not matter. But what I need is a syntax which I can use in FFmpeg commandline which uses the ydif function from the singalstats filter and force ffmpeg to output jpgs at the video position where this big peaks happen. But as I said, I have no idea how I can do it :/ I need a working formular/syntax for that. Do you have any idea how I this yntax would look like?

Is there a filter which can be used for that in combination with the -vframe command? I want to use ONE command line, where the video length is used as 100 percent. And at every 11,1% (100/9) of the timeline I want to generate a thumbnail. I dont need a thumbnail at 0 and 100% ;) because there is mostly black content.

Some forms of TC just lack the space to store higher numbers IIRC (LTC / VITC, perhaps also in MpegII frame headers) But there is logic in not going higher, as it is ‘time’. For a real world use case, in the old days of tape, a reelname most of the time corresponded with the hour. So a production with more than 24 tapes needed better administration in reel names that had to be written on the tape and box. FWIW QuickTime timecode flags includes a "24 hour max" flag to clarify when it is and is not enabled in a timecode track, but >24 hour values are certainly allowed in the QuickTime spec. https://developer.apple.com/library/mac/documentation/QuickTime/QTFF/QTFFChap3/qtff3.html <https://developer.apple.com/library/mac/documentation/QuickTime/QTFF/QTFFChap3/qtff3.html> Dave Rice ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user Hello Dave, as seen in SMPTE S012M Time and Control Code from 1999: Page 2 of 21 pages: "4.2 Time address of a frame Each frame shall be identified by a unique and complete address consisting of an hour, minute, second, and frame number.

[FFmpeg-user] Why is it possible to set a timecode with 24:00:00:00 and beyond?
FFmpeg allows me to set a timecode of 24:00:00:00 and beyond. e.g "-timecode 24:00:00:00" When I make an MXF D10 for example, the value of 24:00:00:00 is still in the file. Most but not all programs ignore this and display 00:00:00:00 correctly. Here are some sample extractions of the timecode offset value in different mxf d10 files generated by ffmpeg: PAL 25fps: -timecode 12:34:56:11 -> in file: 11477b hex -> 1132411 dec -timecode 10:00:00:00 -> in file: 0dbba0 hex -> 90 dec -timecode 20:00:00:00 -> in file: 1b7740 hex -> 180 dec -timecode 23:59:59:24 -> in file: 20f57f hex -> 215 dec -timecode 24:00:00:00 -> in file: 20f580 hex -> 216 dec -> 24h -timecode 24:00:00:01 -> in file: 20f581 hex -> 2160001 dec -timecode 25:00:00:00 -> in file: 225510 hex -> 225 dec -> 25h NTSC 30fps -timecode 23:59:59;29 -> in file: 2782df hex -> 2589407 dec -timecode 24:00:00;00 -> in file: 2782e0 hex -> 2589408 dec Why is this possible to set a timecode after 23:59:59:XX?

Re: [FFmpeg-user] Decode FFV1 AVI back to DPX
Hello Abhi, can you give me/us an DPX sample (one singular DPX file which respresents the source), just to check if it is 16 or 10bit. You can test if you get the orginal dpx files back via the framemd5 option in ffmpeg. You make for every frame an md5 checksum via: ffmpeg -i inputfile -an -f framemd5 outputtextfile.txt Do this for the inputs DPX sequence and for the output dpx sequence. Then compare both files -> If the txt files are equal, then it was lossless. Comparing can be done for example with notepad++ inlcuding the COMPARE plugin (both open source). But: Do your DPX file have linear or logarithmic values? You may check this with MEDIAINFO. (also open source) If the values are/were logarithmic -> then the backtranscodng to DPX will not be lossless.

Hello I need to know how -ac channelcount is exactly working. In the documenetation following is mentioned: -ac[:stream_specifier]channels(/input/output,per-stream/) Set the number of audio channels. For output streams it is set by default to the number of input audio channels. For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options. But there is nothing descriped for these usecases: Inputfile has 2 channels (1stream) - outputfile setting -ac 8 (8channels, 1 stream) Inputfile has 8 channels (1stream) - outputfile setting -ac 2 (2channels, 1 stream) I tested a Stereo file to encode into IMX50 with 16bit audio an 8ch. The stereo pair was correctly placed at ch1 and ch2. The other 6 channels were silent (correct). Is this behaviour standard for -ac ? Or is there any mixing made in some cases? (8ch - 2ch?)

[FFmpeg-user] How to force input-fieldorder and other fieldorder questions
Hello I want to use this filter: https://ffmpeg.org/ffmpeg-filters.html#fieldorder But for that I have to tell ffmpeg that the inputvideo has field order X to get fieldorder Y at the output. But how can I do that? (I dont want to reencode the content with -vf setfield=X.) Example: I want to transcode a TFF source to a BFF target by shifting the picture one line. At the yadif filter I can say to the filter that the incoming video has field order X. How can I do that generally for ffmpeg? Is this list correct? # -vf fieldorder=tff / -vf fieldorder=bff - transforms the field order by shifting the picture # -vf setfield=tff/-vf setfield=bff - just sets the field order of the frame without changing the frame Some questions: # -top 0 / -top 1 - is this a debrectaed version of the fieldorder filter? Or does this something else? # -ildct- is this only for DCT based codecs or can this flag also be used for ffv1 (wavelet) for example?

[FFmpeg-user] How to set interlaced encoding for interlcaed DNxHD formats (220x/185x/220/145/120)?
Hello, I have the problem that I cannot set interlaced as encoding format for DNxHD 220x/185x/220/145/120 I think I use the wrong syntax for setting the field order: -vf setfield=1 or -top 1 both are not working.

Re: [FFmpeg-user] IMX50 NTSC framesize differs to the SMPTE 356M-2001 Standard - why?
Hello Tim, for IMX30 PAL/NTSC I have the same values like you. whats your buffers/init_occupancy for IMX50 NTSC? Not sure I've ever had to do it, but a colleague uses an exact 5000 bit rate which gives a 1668334 buffer and frame size of 208541 if all figures are rounded to integers. These files have generally been accepted the other side of the Atlantic. As I've said before, the coder has got to reconcile a conflicting set of integer values when dealing with NTSC frame rates. It would be itneresting to diff frames made using the values above to those made using your values derived by working back from the exact integer frame size instead of forward from the bit rate. So I dont have to set the buffers/init_occupancy an general or just in the NTSC case? All what I have to set is the videobitrate itself? Current syntax part: -minrate 4840 -maxrate 4840 -b:v 4840 -bufsize 1668328 -rc_init_occupancy 1668328 Alternativ syntax: -minrate 5000 -maxrate 5000 -b:v 5000 So there is no need to set bufsize and rc_init_occupancy?

For an I frame only format motion estimation is not applicable. So I would say that ilme has nothing to do with Intra frame encoding. GOP structures in MPEG2 and MPEG4? If yes, this should be explained in the documentation, I think. But it isnt. Unless the flag performs some other undocumented fuction as well it ought to be redundant.

Re: [FFmpeg-user] How to change FPS without re-render
Hello, you want to speed down 24fps to 23.976 fps? I always need to speed up 23.976fps material to 25fps (PAL): I use this videofilter: -vf setpts=0.95904*PTS -r 25 (23.976/25=0.95904) So maybe for your case this should work: (24/23.976=1.001001001001) -vf setpts=1.001001001001*PTS -r 23.976 But this only works with reencoding. But if you transcode from apple pro res to apple pro res the quality loss should be very small. best regards Christoph ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
Re: [FFmpeg-user] IMX50 NTSC framesize differs to the SMPTE 356M-2001 Standard - why?
yes, this happens because 50mbit/sec is not correct a max framesize of 208541 results in a bit rate of max 49.999840 mbit/sec, IIUC thats what the spec means by 50mbit/sec The spec actually says Up to 50Mb/s and Up to 208541 that being the highest value that comes out below the the 50Mb/s. So I tend to agree with Michael.

Re: [FFmpeg-user] V210 is a packet format but ffmpeg shows always yuv422p10le (planar?) - or how to read a V210.raw stream with ffmpeg?
Did I already ask why you are using ffvhuff? Isnt't this an ancient codec without specification or similar? And not even tested by the archiver community? No, you didnt ;) I/we use this ffvhuff codec as internal working format (SD/HD/2K/4K sources). The final archive format is generated from ffvhuff, and is FFV1. We use ffvhuff because its faster, in future maybe we can use ffv1 instead. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
Re: [FFmpeg-user] V210 is a packet format but ffmpeg shows always yuv422p10le (planar?) - or how to read a V210.raw stream with ffmpeg?
Very, very generally: No, this is the reason why
a decoder is needed: Some applications produce
an incorrect framesize for a given resolution.
But in the case of a given application, the
framesize has to be constant for a given
resolution: If it is not, the file cannot be read.
(And the framesize is of course defined by the
specification for a given resolution but as said,
some encoders use an incorrect stride.)
You can definitely use this syntax to read the
raw files from your capture card, but is should
be way easier to use -f dshow instead.
Yes, I could do this if our card would be supported (Decklink), but we
dont use Decklink cards. :/ We use DVS Cards.

So if I know from which source the content is comming, I want to be able to set the 2 mxf metadata flags, and also the 4 addional falg for the essence (color_range, color_space, color_transfer and color_primaries). Setting the values to a specified values seems straightforward enough, now I have found the relevant UL's. The tricky bit is to decide what to do if the values aren't manually specified. According to the specs there is no default value, so we would have to invent one. Hm, so what is happening at the current ffmpeg encoding? If nothing is defined what is going into the 2 mxf metadata flags? At this time the following is readed out from mxf2raw: Signal Standard = 0 (NONE) Color Sitting = 255 (UNKNOWN) So is ffmpeg writing this 0 into the mxf or is MXF2RAW showing me the some standard value when it cannot regognize any value in this flags? This could be by inspecting the codec metadata to see if the corresponding stream flags are set. This looks like it would be tricksy, or using some predetermined value based upon some other parameters such as frame size, which could lead to disagreement as to what was appropriate. Making the writing of the metadata optional also adds complication in the muxer, so it needs some careful thought. As an interim solution for pristine mxf files, have you tired remuxing with bmxlib? Never tried this way :) I just used mxf2raw to check the files. But I will try this way too. Thank you for the hint. Best Regards Christoph My motivation to this whole issue is: I want to generate a IMX50 file from an ffv or ffvhuff file were the IMX50 target file has less transcoding loss as possible. Most transcoders I use make an internal convertion from YUV422 to YUV422 formats (e.g uncompress 4:2:2 to uncompressed 4:2:2) with an ADDIONAL loss. I guess it is an internal RGB convertion: YUV422 source to RGB (internal) to YUV422 target format. (anyway, these transcoders are black boxes and I cannot know if this is the cause) So when I transcode with these transcoders I have 2 LOSSY steps: 1.) Avoidable LOSS of source is YUV422: addional chroma subsampling (RGB-YUV422) 2.) MPEG2 encoding loss FFmpeg does not do that: It keeps the yuv422 native format and just encode it to mpeg2. - And that would lead to better quality IMX files.

[FFmpeg-user] How can I set in a D10 MXF (IMX50) file the flags for output color_range, -space, -transfer and primaries?
I found out that a IMX50 mxf file encoded with FFmbc and the IMX50 mxf file encoded with actual ffmpeg builds are different in these mxf metadata flags (by reading out via ffprobe - show_streams) FFMBC IMX FILE stream 0:0: color_range=tv color_space=smpte170m color_transfer=bt709 color_primaries=bt470bg FFMPEG IMX FILE stream 0:0: color_range=tv color_space=unknown color_transfer=unknown color_primaries=unknown I want to set these metadata flags to the same values, but with FFmpeg. How can I produce the same output like ffmbc with these 4 metadata flags? I didnt found a answer to that in the ffmpeg documentation :/ Best Regards CHristoph COMMAND LINE OUTPUT: FFmbc encoding: ffmbc -i I:\IMX_tests\IMX50_CARBON.avi -target imx50 -acodec pcm_s24le I:\IMX_tests\_FFMBC_PAL_IMX_24bit_2.mxf -loglevel debug FFmbc version 0.7-rc7 Copyright (c) 2008-2012 Baptiste Coudurier and the FFmpeg developers Input #0, avi, from 'I:\IMX_tests\IMX50_CARBON.avi': Metadata: encoder: Lavf55.0.100 ISMP: 00:00:00:00 Duration: 00:00:20.00, start: 0.00, bitrate: 113291 kb/s Stream #0.0(und): Video: ffvhuff, yuv422p, 720x608p, PAR 152:135 DAR 4:3, 25.00 fps Stream #0.1(und): Audio: pcm_s24le, 48000 Hz, stereo, s32, 2304 kb/s [buffer @ 002EFF60] w:720 h:608 pixfmt:yuv422p tb:1/100 sar:152/135 sws_param: Warning, QMAT_SHIFT is larger than 21, overflows possible Last message repeated 1 times Output #0, mxf_d10, to 'I:\IMX_tests\_FFMBC_PAL_IMX_24bit_2.mxf': Metadata: encoder: FFmbc 0.7 Stream #0.0(und), 0, 1/25: Video: mpeg2video, yuv422p, 720x608i tff [PAR 152:135 DAR 4:3], tbc 1/25, cbr, 5 kb/s, 25.00 fps Stream #0.1(und), 0, 1/48000: Audio: pcm_s24le, 48000 Hz, stereo, s32, 2304 kb/s Stream mapping: Stream #0.0 - #0.0 Stream #0.1 - #0.1 Press [q] to stop, [?] for help [mxf_d10 @ 003BF460] package type:1 [mxf_d10 @ 003BF460] package type:2 [mxf_d10 @ 003BF460] edit units count 0 frame= 341 fps= 25 q=3.0 size= 103570kB time=00:00:13.60 bitrate=62385.4kbits/s eta=00:00:06.41 - FFMPEG encoding: ffmpegnew -i I:\IMX_tests\IMX50_CARBON.avi -map 0:v -map 0:a -c:v mpeg2video -r 25 -pix_fmt yuv422p -aspect 4:3 -minrate 5k -maxrate 5k -b:v 5k -intra -flags +ildct+low_del ay -intra_vlc 1 -non_linear_quant 1 -ps 1 -qmin 1 -qmax 3 -top 1 -dc 10 -bufsize 200 -rc_init_occupancy 200 -rc_max_vbv_use 1 -rc_min_vbv_use 1 -c:a pcm_s24le -ar 48000 -f mxf_d10 I:\IMX_tests \_FFMPEGNEW_PAL_IMX_24bit_2.mxf ffmpeg version N-71727-g46778ab Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.9.2 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-avisynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libblu ray --enable-libbs2b --enable-libcaca --enable-libdcadec --enable-libfreetype --enable-libgme --enable-libgsm --enable-libilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enab le-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libschroedinger --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --ena ble-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable-lzma --ena ble-decklink --enable-zlib libavutil 54. 23.101 / 54. 23.101 libavcodec 56. 35.101 / 56. 35.101 libavformat56. 31.100 / 56. 31.100 libavdevice56. 4.100 / 56. 4.100 libavfilter 5. 14.100 / 5. 14.100 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc53. 3.100 / 53. 3.100 Input #0, avi, from 'I:\IMX_tests\IMX50_CARBON.avi': Metadata: encoder : Lavf55.0.100 timecode: 00:00:00:00 Duration: 00:00:20.00, start: 0.00, bitrate: 113291 kb/s Stream #0:0: Video: ffvhuff (FFVH / 0x48564646), yuv422p, 720x608, 96 kb/s, SAR 152:135 DAR 4:3, 25 fps, 25 tbr, 25 tbn, 25 tbc Stream #0:1: Audio: pcm_s24le ([1][0][0][0] / 0x0001), 48000 Hz, stereo, s32 (24 bit), 2304 kb/s File 'I:\IMX_tests\_FFMPEGNEW_PAL_IMX_24bit_2.mxf' already exists.

[FFmpeg-user] How to generate IRT conform D10 IMX50 MXFs (and how to set the output color_range, -space, -transfer and primaries flags)
Hello I am making tests with IMX50/MXF encodings with FFMBC and FFMPEG. (with 24bit audio) The tests compare the final files with the IRT MXF Analyzer Pro tool to be shure to be IRT conform. (My used syntax is at the bottom of this mail) Both files (generated with ffmbc and ffmpeg) are working very well in editing tools but there is a little difference: The IMX50 generated by ffmbc has no errors/warnings at IRT MXF Analyzer (with16bit audio). It is really perfect. In fact I never had a clean green MXF by testing other probes from other encoding tools. Only the IRT probes itself are clean. So this MXF is IRT conform when using the ffmbc standard target preset imx50. The Analyzis of the IMX50/MXF generated by FFMPEG (latest build from zeganoe) has 1 warning and 1 error: WARNING: Fill Item Key with a wrong RP210 (SMPTE Metadata Dictionary) version number of 0x01. The correct version number is 0x02 ERROR: The Sound Essence Descriptor signals that the number if quantization bits is 24, which is higher than actually required (16) as detemined by parsing the essence. Due to the fact that I am producing 24bit audio I could prevent the WARNING by producing 16bit audio. But is there a problem in the MXF when producing 24bit? Sound works in editing tools. Furthermore ffmbc produces for standard a IMX with 16bit - If I force ffmbc to do 24bit, I get the same error. Due to the warning: I found out that both files are different regarding these values (by reading out via ffprobe - show_streams) FFMBC IMX FILE stream 0:0: color_range=tv color_space=smpte170m color_transfer=bt709 color_primaries=bt470bg FFMPEG IMX FILE stream 0:0: color_range=tv color_space=unknown color_transfer=unknown color_primaries=unknown So my questions are : 1.) How can I produce (with ffmpeg) the same output like ffmbc with these 4 metadata flags: color_range=tv color_space=smpte170m color_transfer=bt709 color_primaries=bt470bg I didnt found a answer to that in the ffmpeg documentation :/ 2.) Maybe somebody knows: Do these 4 metadata flags have a connection to the Warning message of the MXF Analyzer? - Fill Item Key with a wrong RP210 (SMPTE Metadata Dictionary) version number of 0x01. The correct version number is 0x02 If nobody know this answer I could do the test for myself by be able to encode with the upper params in 1.). 3.) Is there an syntax option in ffmpeg for 24bit audio encoding to prevent this ERROR: The Sound Essence Descriptor signals that the number if quantization bits is 24, which is higher than actually required (16) as detemined by parsing the essence.

Re: [FFmpeg-user] How to set 3 specific metadata flags (ITU601/displayoffset) in FFmpegs IMX50 MXF-OP1a encoding?
Therfore I think the only sane approach would be to have them as user settable flags which would take more careful thinking about... Yes, sorry, I didnt said it detailed: Yes a flag which can be enabled by the user would be the best solution for that. Do you think these 2 flags could be implemented in ffmpeg IMX encoding?

Re: [FFmpeg-user] Is it possible to speed up merging-speed from HD to LAN?
(I don't think FFmpeg reads from the output file if that was your question.) That WAS the question ;) I thought you meaned FFmpeg (reads the source file of course) and writes the target file and reads it (for filechecking or something) - And that would be the cause for the slow merging speed from HD to LAN. But you say that you dont think that it will do that, so my question is still the same: why is this so slow over lan? When I have a 1Gbit LAN, why ffmpeg just use 25 percent of the connection speed when I merge or transcode something into lan? I have no idea :( ffmpeg version 2.6 Copyright (c) 2000-2015 the FFmpeg developers I am curious: Why are you using a release? Maybe because you don't know that all releases of FFmpeg contain more bugs than current git head? Yes, I didnt knew that. You have to know that I am not a programmer or a compiler. I am just a user of ffmpeg and mostly I use zeranoe windows builds and sometimes, like in this current case, a own compiled version of a collegue who is able to compile. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
Re: [FFmpeg-user] How to set 3 specific metadata flags (ITU601/displayoffset) in FFmpegs IMX50 MXF-OP1a encoding?
Hello Tim! thank you, it works for PAL and NTSC (720x512/720x480) but there is a just little bug for NTSC when encoding to 720x486 in stored dimension!

Re: [FFmpeg-user] How to set 3 specific metadata flags (ITU601/displayoffset) in FFmpegs IMX50 MXF-OP1a encoding?
Don't know if its relevant but your coding parameters are slightly different to the one's I use for D10, and I wonder if this affects the automatic metadata insertion.. -flags +ildct+ilme+low_delay Well ilme seems kind of redundant for I frame only coding but probably harmless. -tag:v mx5p irrelevant for mxf, but again probably harmless. I use the following which you do not:- -rc_max_vbv_use 1 -rc_min_vbv_use 1 and you use the following that I do not:- -qmax 3 -rc_buf_aggressivity 0.25 I don't know what difference, if any, those changes make, but the values I use create D10 files that BBC RD looked at and thought were OK. Perhaps worth a try? [..] Additionally: I tried it again with all your mentioned syntax changes but without changing the -qmin 1 -qmax 3 - now it works to encode. But the MXF metadata doesnt change (SIGNAL STANDARD = 1 (ITU 601) + display y offset +Color siting = 4 (Rec 601). The only difference I saw with mediainfo is that the new MXF (your syntax) has a CLOSED GOP structure and the old one (my syntax) had a OPEN structure.

Re: [FFmpeg-user] Questions about readout important metadata from DPX files (logarthmic/linear) and recreate DPX with same metadata
But let me try it differently: You have an input file with a logarithmic colour space that is not supported by FFmpeg. If you are sure that you know what you are doing, you can of course use FFmpeg to compress your raw data (I believe ffv1 was tested much better already but this is not really related). But while the data will still be identical the colourspace will be linear because FFmpeg only supports linear colourspaces. So you will will have to know that the actual content is logarithmic when you use it again (or write the transfer information when creating the file). yes that is what I am planing to do. Additional: I tested a LOG C ARRI ProRes444 file (logarithmic values) to convert it to a linear ffvhuff. For that I used a specific LUT file from ARRI and the 3dlut videofiler. That works good. ffmpegnew -i I:\ARRI SAMPLE FILES\J001C048_140110_R6MS.avi -vf format=pix_fmts=rgb48, lut3d=file=AlexaV3_K1S1_LogC2Video_Rec709_EE_davinci3d.cube -vcodec ffvhuff -pix_fmt yuv444p10le -acodec copy I:\ARRI SAMPLE FILES\J001C048_140110_R6MS_corrected.avi So, if I can readout the information that the input video file or input DPX file has logarithmic values I can a) keep the logarithmic encoding in the ffv1 archive file and save the metadata information in an external file/database or b) I decide to linearize it with LUT and 3dlut filter to have a linearized master in the archive beneath the original DPX file of course. But, the readout of the metadata has to be made with mediainfo at this time. It would be very useful if FFmpeg would get a more detailed metadata readout function for DPX files. At least for readout of the logaritmic/linear information and the FrameRate information - FFmpeg always thinks that the fps of my DPX files ar 25fps. There exist one DPX metadata reader/editor only for MAC OS. Which this tool I checked the FrameRate values in the DPX: most DPX had no value written, so ffmpeg GUESSES the fps I think. One DPX had the value 24fps, but FFmpeg also showed me 25fps. Anyhow: I am not shure if this metadata reader is THE reference application for DPX. :/ I just mentioned it that there are more informations in the DPX than ffprobe is able to show me. br Christoph ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
Re: [FFmpeg-user] Questions about readout important metadata from DPX files (logarthmic/linear) and recreate DPX with same metadata
We've encountered something similar when transcoding FFV1 over the network. So we used framemd5 not to verify FFV1's losslessness, but to validate that the transcoding goes error-free :) FFmpeg's framemd5 became *the* feature for professional video preservation. So, thanks again for all your great work here! Regards, Pb Indeed, ffmpeg framemd5 is my only possibility to check lossless transcodings. A BIG THANK YOU FOR THAT! Otherwise I could only test it to make it visually with e.g After effects overlay the transcoded video to the original and make a DIFFERENCE/DELTA video... (btw: some videotechnicians do that, because they dont know about ffmpeg or framemd5 ;) With the framemd5 checksum I can check many Lossless transcoders if they do their job correct when using lossless codecs, and I was wondering how many professional transcoders are destroying the video when transcoding from lossless formats like uncompressed 4:2:2 10bit (v210) to the same output format (v210) (because of an internal YUV422-RGB blowup I guess).

Re: [FFmpeg-user] Questions about readout important metadata from DPX files (logarthmic/linear) and recreate DPX with same metadata
3.) How can I read out the DPX Version information like mediainfo does? (Version 2) Could you explain the usecase? The usecase is to log the archive ingest process. In this log there are different informations like: CreatingSoftware (ffmpeg, premiere etc), FileFormat, FileFormatVersion (if versions are existing). So you can see what was going into the archive whichout searching and opening the DPX file themself.

What is unclear about this error message? (Note that I usually don't request an increased loglevel because it can make seeing the actual issue more difficult like in this case.) The error message is meant to be shown in red to make it easier to read: Does this not work on your terminal? Hello Carl the error message is shown in red, right :) It was my mistake. I ignored it frivolously, because I was used to be ffv1 always choose automatically the coder 1 if the pixfmt is higher than 8 bit, because: if I choose yuv pixel formats with more than 8bit like these examples : yuv422p10le yuv422p16le yuv444p10le than the ffv1 encoder automatically forces to CODER 1 as seen here: [ffv1 @ 003a6040] bits_per_raw_sample 8, forcing coder 1 Now I am testing rgb pixelformats higher than 8bit like gbrp10le (which I did not before), and it does not change automatically to CODER 1: [ffv1 @ 003a6020] bits_per_raw_sample of more than 8 needs -coder 1 currently (IN RED COLOR) Do you have any idea why ffv1 only changes the coder automatically in yuv pixel formats?
