[FFmpeg-user] Sony FX3 timecode (or the lack of it...)
This cam writes Mp4 without a QuickTime timecode track, but it does write
’something’ that ’should’ be (about) correct. (It’s a known issue it’s off by
one or two frames when slaved.)
ffprobe -v error -print_format json -show_format -show_streams
/Users/bouke/Downloads/Sony\ FX3/PRIVATE/M4ROOT/CLIP/20240227_C6917.MP4

Now, where is this TC stored? I cannot find it using a HEX editor.
And, more important, FCP, Avid MC and Resolve interpret the “timecode” as Drop
frame, where there is no indication of that in FFmpeg / FFprobe.
Can anyone shed a light on this?
thx,
Bouke

[FFmpeg-user] Hyper fast gone in Gyan's binaries
For my work I try an install of FFmpeg by running it without any params. It used to be that the return would include ‘Hyper fast’. However, the current binaries from Gyan do not include that, but state ‘Universal media encoder’. What would be a good, future proof way of testing if FFmpeg is indeed installed / running properly?

This way FFplay will get just samples, bypassing whatever happens on restart playback of the file.

This IS a serious problem, same as stripping audio only from video has become dog slow. FFmbc used to be able to do that (with -c:a copy) at the speed of drive, FFmpeg nowadays seems to read the entire file, including video. > > Dunno what command you use for reverse direction so can not help you on > that one. My filter compex is HUGE, it splits all inputs to mono, pads / merges / etc. (I’m doing auto sequence style.) But for now, I’ve got something more to toy with.

[FFmpeg-user] Wave channel split is very slow
Trying to split a 64 channel 48Khz 24 bits Wave file. That is VERY slow. ffmpeg -i /Volumes/Data/magweg/64channel.wav -filter_complex "[0]pan=mono|c0=c0[tr0]" -c:a pcm_s24le -map "[tr0]" /Volumes/Data/magweg/64_test/out_1.wav Runs at about 15x But if I do all 64 in one pass, it slows down to about 0.7x I don’t get it. DiskIO should not be a factor, and there is no math involved. (Granted, the ppm_s24le might involve math, but that should be simple.) Is this a bug? (Same happens vice versa, going from multiple non-interleaved to one big interleaved Wave.)

Much appreciated. Mind you: Sometimes it’s wanted / needed to have all files ’the same’. If that is interlaced, it’s interlaced. Codec should say ‘interlaced’, no matter the actual content. For Avid media, that might (depending on the version of MC) be important for a ‘fast import’, or omitting adapters you don’t want / need. In broadcast, over here interlaced is mandatory, even if the content is progressive. So no, it’s NOT complicated, and no, it’s NOT outdated.

[FFmpeg-user] Directshow capture and irregular timing of output to StdErr
Trying to build a metering tool that displays (almost) RT values. On Mac, all works fine with AVfoundation, but on Win with Directshow I have an issue: C:\Users\Bouke>ffmpeg.exe -nostats -f dshow -ar 48000 -i audio="Line (Steinberg CI2)" -filter_complex "ebur128=peak=true" -f null - Now, this works fine, BUT, the output to stderr is at very irregular intervals. Output is as expected lines like: [Parsed_ebur128_0 @ 01915fe77a40] t: 0.199979 TARGET:-23 LUFSM:-120.7 S:-120.7 I: -70.0 LUFS LRA: 0.0 LU FTPK: -55.5 -71.0 dBFS TPK: -55.2 -69.8 dBFS [Parsed_ebur128_0 @ 01915fe77a40] t: 0.299979 TARGET:-23 LUFSM:-120.7 S:-120.7 I: -70.0 LUFS LRA: 0.0 LU FTPK: -56.2 -72.7 dBFS TPK: -55.2 -69.8 dBFS Now, sometimes one line is outputted (as expected) but most of the times it’s 2 up to 4 lines at the same time. That does not make for a pretty visual show if I parse it ‘as fast as possible’ I could buffer the output and do my display stuff for each line with my own interval / if buffer line length >= 4 or alike, but that would introduce half a second delay, and that does not compute well in my brain when I have to ride the faders… Is there anything I can do to have FFmpeg spit out each line ‘as soon as it is available’? (I’m starting FFmpeg from Python, listening to StdOut / StdErr.) Below the full command, what you cannot see is the irregularity in when the lines arrive….

I don’t get it. Faststart is for internet / network playing only, when the entire file is not yet available. If movflags faststart is needed, it should be darn fast as your files ’should’ be fairly small, as they are intended for (relative) low bandwith. There is NO penalty for having the MOOV atom at the end if a file is local, as parsing all atoms will not take longer than a few secs if the file is local. Having said that: Checking the size of the moov atom is relative simple, use ‘any’ atom parser, or render the same file for 1 frame with a scale as small as you can get, with highly compressed sound and use the entire file size for the MOOV atom size (plus a bit).

From experience I know that the size of -f segment for Wave does NOT result in a sample accurate amount of data, not sure if that is what you are facing.

In that case, save the filter_complex string to a file, then, instead of filter_complex you can use filter_complex_script with the filename as argument.

Re: [FFmpeg-user] Changing scan type (progressive<->interlaced) without reencoding.
It’s no problem at all. Btw, it’s very common to store progressive as interlaced, as broadcast still requires interlaced material, no matter how it is shot. From memory, just do a -c copy and you’ll end up with the source in a progressive container.

Open the .avi with VLC and turn OFF de-interlace, you’ll see how gorgeous the motion was on an old fashioned interlace aware screen. So, you need to de-interlace the filter. While you’re at it, you should crop a little, as SD is an over scanned format. And, you have non-square pixels that you have to accommodate for, so set aspect to 4:3 (in this case), or scale to a 4:3 ratio.

In this case upto 6 mb file size is fine. State what you want, do you want to trim (cut out parts), just to forward it to other people?

If you need ’some’ kind of computer logic / analysis, uncompressed Wave / PCM CAN be faster / more efficient than compressing it. In that case, file size does not matter if it’s local, it’s just math on what is cheaper / more efficient. BUT, since you don’t give any clue what / who has to process the output of your work, trust me, hire a specialist to drag this out of you.

Having a .wav extension on your input DOES NOT mean your input is uncompressed Wave PCM. (Wave Can be compressed, in your case, you have OGG compression with a .wav extension.) What do you expect / why are you doing this? The quality of your file will NOT get better, nor will the file size get significant down if you process it. Concerning your lack of knowledge, the only thing you can accomplish is making things worse.

Now, IMHO, audio mapping in FFmpeg is plain stupid. FFMBC’s approach what so much easier / better. (On top of that, ripping just sound from an AV file with FFMBC was WAY faster, as FFMBC was able to ignore the video data, where FFmpeg seems to feel a need to plough trough it.)

But yes, it will level it if needed, to stick to the reference. I'm missing out on the ‘analog’ reference. AFAIK, YUV is still in use in (digital) codecs.

AFAIK, YUV = R-Y B-Y, so it’s just math. Doing corrections in RGB is simpler for a mortal, but should / could result exactly the same.

[FFmpeg-user] Does recording stops without encoding the buffer?
Trying to record two streams with something like this: ffmpeg -hide_banner -thread_queue_size "35012" -f "decklink" -queue_size "1073741824" -raw_format "auto" -format_code "Hp25" -channels "2" -timecode_format "rp188ltc" -video_input "sdi" -audio_input "embedded" -audio_depth "16" -i "bm mini Two" -timecode "09:13:28:04" -metadata:s:v:0 "reel_name=Reelname" -filter_complex "[0:v]split=2[out1][out2]" -map "[out1]" -map "0:a" -c:a "pcm_s16le" -c:v "prores" -profile:v "0" -vendor "ap10" -pix_fmt "yuv422p10le" "/Volumes/Data/09-09-2021/669.mov" -map "[out2]" -c:v "libx264" -preset "ultrafast" -g "30" -pix_fmt "yuv422p" -tune "zerolatency" -aspect "16:9" -f "tee" -map "0:v" "[f=mpegts]udp://127.0.0.1:1230" Stop recording by sending 'q' to both instances (at about the same time) Now, sometimes one of the recordings is way shorter than the other, and does not hold all video as expected. My guess (I don't have access to the machine it's running on now) is that the buffer isn't processed after the 'q' is received. Could this be the case? If so, any workaround?

Thinking of it, for Netflix delivery, there also have to be stems. So a silence detection of the dialogue stem should provide data for timeline measuring.

Hi Carl Eugen, Sorry, my bad, I should have seen that one coming. Nevertheless, I can see some possibilities: Redo / reverse engineer the dialog gating with ’some’ filter, and implement 1770-1. It does not need to be exact the same as Dolby wants, as Netflix allows for +/- 2 LU. (And that’s a lot I woud think.) Another option perhaps could be that I pay someone for a custom version that I can distribute. (In which case I need to do the Dolby dance.) What do you think?

[FFmpeg-user] ITU-R BS.1770-1 (Netflix) audio measurement
I'm using the R128 functionality now, but Netflix wants sound to be Dolby dialogue-gated measured. Seems that the needed Dolby code is free now.

[FFmpeg-user] FFmpeg capture, mkvtimestamp_v2, vsync 0 and timecode don't play nice
Trying to capture and modify the TC in-file afterwards. I've found a nice way to store the timestamps from the capture. (https://stackoverflow.com/questions/53391150/ffmpeg-obtain-the-system-time-corresponding-to-each-frame-present-in-a-video) This works fine using this line: ffmpeg -hide_banner -f "decklink" -queue_size "1073741824" -raw_format "auto" -format_code "Hi50" -video_input "sdi" -i "bm mini One" -filter_complex "settb=1/1000,setpts=RTCTIME/1000-15000,mpdecimate,split[out][ts];[out]setpts=N/25/TB[out]" -map "[out]" -c:a "copy" -c:v "prores" -profile:v "1" -vendor "ap10" -pix_fmt "yuv422p10le" "/Volumes/Data/tst1.mov" -map "[ts]" -f mkvtimestamp_v2 "/Volumes/Data/time.txt" -vsync 0 But, when I add -timecode "00:00:00:00" (to force a TC atom in the output), horrible things happen. ffmpeg -f "decklink" -queue_size "1073741824" -raw_format "auto" -format_code "Hi50" -video_input "sdi" -i "bm mini One" -filter_complex "settb=1/1000,setpts=RTCTIME/1000-15000,mpdecimate,split[out][ts];[out]setpts=N/25/TB[out]" -map "[out]" -timecode "00:01:00:00" -c:a "copy" -c:v "prores" -profile:v "1" -vendor "ap10" -pix_fmt "yuv422p10le" "/Volumes/Data/tst1.mov" -map "[ts]" -f mkvtimestamp_v2 "/Volumes/Data/time.txt" -vsync 0 The timecode does not run at the video speed, skips a frame or two here and there, and the image freezes after a random amount of time (between 10 seconds and a minute or so). How come the timecode can mess up stuff that much? From what I understand it's just a couple of atoms in the moov atom, and a reference where the actual TC value (as frames) is stored in the mdat. I highly suspect the -vsync 0 to also work on the video. If I omit that, the video is fine, the TC is fine, but there is no metadata output, just the # timecode format v2 The alternative to this dance is to use -timestamp_align, but I also want to use non-decklink audio, and I can’t get that in sync. (Using -ss for sound is not accurate.)

[FFmpeg-user] XDcam MXF wrong field order
Trying to make broadcast compliant (XDcam style) MXF files, but those fail on wrong field order, if the source is progressive. This used to work fine. (ffmpeg version 3.2.2 has no issues with this, and has done literally thousands of good / compliant files) FFmpeg always reports "top coded first (swapped))", and MediaInfo says: Scan order : Bottom Field First If I swap out -top 1 for -field_order tt it does not help at all. Now, it ’should’ not be an issue, except that Baton / pre baton scripts bitch about it, and the files get rejected.

Hi Moritz,
I know, but there was ’nothing’ on stdErr / stdOut.
It turns out that FFmpeg crashes, nothing wrong with the command line.
QProcess sees an error, and either QProcess terminates FFmpeg (I don’t think
so) or FFmpeg crashes by itself.
Strange thing is, the EXACT same line works from the terminal.
I’m pretty sure that it’s not something in my code. I’ve ran a gazillion
decklink captures. Trouble starts when I want to use avfoundation.
in Python:
cmd = "bash"
args = ["-c", "/Applications/ffmpeg -loglevel trace -report -f avfoundation -i
:0 /Volumes/Data/test.mov"]
self.proc = QProcess(self._main)
self.proc.finished.connect(self.renderdone)
self.proc.errorOccurred.connect(self.erroroccured)
self.proc.start(cmd, args)
print("cmd is now", self.proc.arguments())
self.proc.readyReadStandardOutput.connect(lambda:
self.readStdOutput(self.proc))
self.proc.readyReadStandardError.connect(lambda:
self.readStdErr(self.proc))
Attachments don’t seem to work for me, so I copy / paste the reports below,
first the failing one from Python, then the working one from the terminal.
Anything else I can do to figure out why the same line does not work fired from
Python?

On ‘clean’ machines I still get:
dyld: Library not loaded: /usr/local/opt/freetype/lib/libfreetype.6.dylib
But at least I have a bit hope my client is able to run the script.
thx,

[FFmpeg-user] Failed / strange build script
Hi all, I’ve downloaded a FFMpeg build script and altered it to my liking (Added Decklink support / drawtext) running the script as ./build-ffmpeg -b --enable-gpl-and-non-free Now it does build on a Catalina system, but fails on a Big Sur.

"UTC modulo timestamp_align", as a whole. Well yes, I do know a little math. BUT, it does not work. Setting a timestamp_align of 6 seconds results in a start delay of just 6 seconds… I’ll continue testing, but for the concept: What I need is to compensate for the time it takes FFmpeg to start. So, what I really need is: ’start capture if time > x seconds since epoch’ (or something like that.) Otherwise, what’s the use? What am I missing here?

If i enter 0, it starts capturing immediately, higher values do give ‘a’ delay, but it’s not predictable at all.

[FFmpeg-user] Decklink timestamp_align, what should it do?
From the manual: 'timestamp_align Capture start time alignment in seconds. If set to nonzero, input frames are dropped till the system timestamp aligns with configured value Ok, when I put -timestamp_align in my command, it does wait ‘a bit’ before starting capture. That’s what I’m after, but i have no clue how long it waits. It’s not a ‘wait X seconds’ for sure. So my question, what is 'the system timestamp’? How do I get it so I can enter the correct value? thx Bouke ___ 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".

[FFmpeg-user] Media Express vs FFmpeg CPU use
Trying to capture decklink input to ProRes. FFmpeg is VERY cpu hungry (230 % on my sytem in the example below, increasing when upping the quality of Prores) Media Express / VTEncoderXPCservice use just half the CPU. Is there a way to speed up FFmpeg in a similar way? (Eventually I want to do multiple streams on a single machine.)

Re: [FFmpeg-user] drawtext timecode from metadata
Hmm,
I’m pretty sure I saw a reply from Gyan, stating ’not possible, how are you
capturing, i’ll look into something’
few seconds later that was gone. (Or I really need to up my medicine…)
Anyways, I’m dong a BM capture, with TC coming in embedded over SDI.
(I must admit I have not yet tested it with BM capture, just with a local file.
The TC as metadata in a Qt atom works just fine.

[FFmpeg-user] drawtext timecode from metadata
trying to capture and burn in TC at the same time.
Burn in TC works if I specify the start TC, but I can’t probe and then record,
as that takes time so the TC will be off.
So I’m hoping to set the drawtext filter on the fly, I tried:
drawtext=timecode=%{metadata\\\:timecode}:
-filter_complex
"[0:0]drawtext=timecode=%{metadata\\\:timecode}:fontfile='/Volumes/Data/fonts/courbd.ttf':r=25:x=(w-tw)
- (w * 0.02): y=h-(2*lh):fontsize=54.0:fontcolor=white”
This does not work, gives me:
[Parsed_drawtext_0 @ 0x7ff9fbe0cb40] Unable to parse timecode, syntax:
hh:mm:ss[:;.]ff
Is there a way to do this?

[FFmpeg-user] Local latency with FFplay
Trying to view a stream while recording. (That 'sorta kinda' works with a tee and udp streaming, but has a horrible delay.) eg: I start FFplay: ffplay udp://127.0.0.1:1230 -x 320 -y 240 -left 100 -top 100 -alwaysontop Then: ffmpeg -f decklink -i UltraStudio Mini Recorder -raw_format auto -format_code Hi50 -channels 2 -timecode_format none -video_input sdi -audio_input embedded -audio_depth 16 -vcodec libx264 -preset ultrafast -pix_fmt yuv422p -tune zerolatency -an -s 320x180 -aspect 16:9 -map 0:v -f flv udp://127.0.0.1:1230 This results in a latency of 6 seconds (Ok, no local file, but with it and a tee it’s the same) So, back to the drawing board and trying something simple, piping directly from FFmpeg to FFplay. ffmpeg -i yadda - | ffplay - this takes 2 up to 6 seconds before the FFplay window is shown (Depending on the phase of the moon divided by the temperature or something, I am clueless why there is a difference), and the video is still horrible delayed (app by the same time as it took FFplay to start / show the video). If I add a -ss 2 to FFplay, there is just a couple frames delay, but the startup time of FFplay is doubled. Funny enough, without -ss 2 the video could be 6 seconds late, with -ss 2 it's very close. (good enough for rock 'n roll, except for the 12 seconds start time...) Any pointers? Ideal would be to keep FFplay open, and start / stop FFmpeg for recording, or just viewing the incoming signal. thx, Bouke bouke@Boukes-iMac ~ % /usr/local/bin/ffmpeg -f decklink -i "UltraStudio Mini Recorder" -format_code Hi50 -raw_format auto -s 320x180 -aspect 16:9 -map 0:v -an -vcodec libx264 -preset ultrafast -f flv - | /usr/local/bin/ffplay - ffplay version git-2021-03-31-b3e9a84 Copyright (c) 2003-2021 the FFmpeg developers built with Apple clang version 12.0.0 (clang-1200.0.32.29) configuration: --enable-videotoolbox --enable-nonfree --enable-gpl --enable-lv2 --enable-openssl --enable-libsvtav1 --enable-libx264 --enable-libx265 --enable-libvpx --enable-libxvid --enable-libvidstab --enable-libaom --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libtheora --enable-libfdk-aac --enable-libwebp --enable-libsrt --disable-debug --disable-doc --disable-shared --enable-pthreads --enable-static --enable-small --enable-version3 --enable-decklink --extra-cflags='-I/Users/bouke/ffmpeg-build-script/workspace/include -I/Users/bouke/ffmpeg-build-script/include' --extra-ldexeflags= --extra-ldflags='-L/Users/bouke/ffmpeg-build-script/workspace/lib -L/Users/bouke/ffmpeg-build-script/include' --extra-libs='-ldl -lpthread -lm -lz' --pkgconfigdir=/Users/bouke/ffmpeg-build-script/workspace/lib/pkgconfig --pkg-config-flags=--static --prefix=/Users/bouke/ffmpeg-build-script/workspace ffmpeg version git-2021-03-31-b3e9a84 Copyright (c) 2000-2021 the FFmpeg developers built with Apple clang version 12.0.0 (clang-1200.0.32.29) configuration: --enable-videotoolbox --enable-nonfree --enable-gpl --enable-lv2 --enable-openssl --enable-libsvtav1 --enable-libx264 --enable-libx265 --enable-libvpx --enable-libxvid --enable-libvidstab --enable-libaom --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libtheora --enable-libfdk-aac --enable-libwebp --enable-libsrt --disable-debug --disable-doc --disable-shared --enable-pthreads --enable-static --enable-small --enable-version3 --enable-decklink --extra-cflags='-I/Users/bouke/ffmpeg-build-script/workspace/include -I/Users/bouke/ffmpeg-build-script/include' --extra-ldexeflags= --extra-ldflags='-L/Users/bouke/ffmpeg-build-script/workspace/lib -L/Users/bouke/ffmpeg-build-script/include' --extra-libs='-ldl -lpthread -lm -lz' --pkgconfigdir=/Users/bouke/ffmpeg-build-script/workspace/lib/pkgconfig --pkg-config-flags=--static --prefix=/Users/bouke/ffmpeg-build-script/workspace libavutil 56. 63.101 / 56. 63.101 libavutil 56. 63.101 / 56. 63.101 libavcodec 58.117.101 / 58.117.101 libavformat58. 65.101 / 58. 65.101 libavcodec 58.117.101 / 58.117.101 libavdevice58. 11.103 / 58. 11.103 libavformat58. 65.101 / 58. 65.101 libavfilter 7. 96.100 / 7. 96.100 libavdevice58. 11.103 / 58. 11.103 libswscale 5. 8.100 / 5. 8.100 libavfilter 7. 96.100 / 7. 96.100 libswresample 3. 8.100 / 3. 8.100 libswscale 5. 8.100 / 5. 8.100 libpostproc55. 8.100 / 55. 8.100 libswresample 3. 8.100 / 3. 8.100 libpostproc55. 8.100 / 55. 8.100 [decklink @ 0x7f87ec80f000] Autodetected the input mode [decklink @ 0x7f87ec80f000] Found Decklink mode 1920 x 1080 with rate 25.00(i) Guessed Channel Layout for Input Stream #0.0 : stereo0B f=0/0 Input #0, decklink, from 'UltraStudio Mini Recorder': Duration: N/A, start: 0.00, bitrate: 830976 kb/s Stream #0:0: Audio: pcm_s16le, 48000 Hz, stereo,
[FFmpeg-user] OT, Noise, am I'm loosing it? (rant)
Recently watched ‘Win it all’ on Netflix. (Ok, you can flame me for bad taste, but that would be beside the point.) Now, in this flick, a ‘Netflix original’, noise on close to every interior shot is beyond reasonable. Now, Netflix has very high demands on delivery. How could this happen? Why did Netflix accept this? (And this is far from the only noisy shot I see in modern movies nowadays….) This movie was shot some 5 years ago. Even back then there were cams that could shoot with candle light if needed, without excessive noise! I guess this is due to shooting LUT by someone who is totally clueless. (Note, my guess is that even without additional lighting the shots ‘could’ have turned out with way less noise.) Having said that, I have never ever seen a LUT shot that turned out better than shooting decent in the first place, but my editorial work has productions with a total budget of 300K max. I know there is a place in this world where shooting LUT can indeed help, my guess is that those events are 0.1 % of the cases where LUT is in fact used. If the noise would be an artistic decision I could understand it, but that seems not the case IMHO. Nor was it out of need. (I have some experience, I have restored old movies, where the only available stock needed to be overcranked, there is a valid reason.) What I do know that the added data for compression for Netflix will burn half a rain forrest, consuming way more energy / cost than having had the set lighted properly, or, again, pick a decent camera and do NOT shoot lut, or do it properly at least. What am I missing, or am I right and should some people get their butts kicked?

For the archives: Fixed. trouble was that Premiere / Resolve expect the co64 atom INSTEAD of stco, rather than after to overwrite previous value.

[FFmpeg-user] co64 atom in QT / Mp4, and compatibility with Premiere
This is not an FFmpeg question perse, but I hope someone knows more about atoms than I do. Similar to the previous thread, I am modifiying clips ‘in place / destructive’. (For .Mp4 / .mov files) For that I re-write or re-order the moov atom to needs. That all seems to work fine, if files are < 4 gig. On larger files, when I want to change TC, I add an mdat atom with the TC converted to frame number. In the TC track (That I rip from a dummy FFmpeg short transcode), I change the pointer in the TC tracks stco atom to the newly added mdat location. So far so good. Now, when the new mdat pos goes over 4 gig, I add an co64 atom so I have 8 bytes to set it, and I change the whole shebang to reflect the new length of all atoms in the structure. This also ‘sorta kinda’ works, as QT player displays the correct TC. BUT, Adobe Premiere does NOT like this, it gives me another TC that I can’t place for the life of me… If I omit the co64 atom and find ‘some’ spot (either inside an mdat atom or not), it works, but it seems Premiere totally ignores the co64 info. Can anyone shed a light on this?
