[FFmpeg-user] Determining colour matrix coefficients detected and used by ffmpeg
Hi All, In some of the sources I work with the convention of SD=BT.601 and HD=BT.709 isnt always followed. That makes it necessary to confirm that ffmpeg correctly detects and handles input colour space matrix coefficients. Unfortunately I cant find any way to show this information during input parsing, nor in the output produced by ffmpeg. Ill be very grateful for any pointers to help solve this. Some sample encodes below. These are not necessarily from problem inputs, but show that colour matrix coefficient information does not seem readily available unless I am hopefully overlooking something. Note that even color_range is not uniformly available from encodes. ffmpeg 1 ffmpeg started on 2014-09-21 at 13:59:27 Report written to ffmpeg-20140921-135927.log Command line: ffmpeg -i input_file.avi -report test_out.mpg ffmpeg version N-66232-g5e3da25 Copyright (c) 2000-2014 the FFmpeg developers built on Sep 10 2014 22:01:59 with gcc 4.8.3 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-avisynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libfreetype --enable-libgme --enable-libgsm --enable-libilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libschroedinger --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable-decklink --enable-zlib libavutil 54. 7.100 / 54. 7.100 libavcodec 56. 1.100 / 56. 1.100 libavformat56. 4.101 / 56. 4.101 libavdevice56. 0.100 / 56. 0.100 libavfilter 5. 1.100 / 5. 1.100 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc53. 0.100 / 53. 0.100 Splitting the commandline.

Or at least with a capture software that gives you the original dv stream? (Or do I misundertand?) ffmpeg catches up with the end of the .m2t file which dvgrab is writing, it crashes with an incomplete frame error. Crash reports need backtrace, register dump and disassembly / command line and complete, uncut console output missing.

Please test current git head, releases are only supported here if you are a distributor yourself. Getting anything by git is impossible on dialup. 10Mb per hour, 4 hour maximum connection. Sounds like one more reason to use git. Thus the act of getting stable releases does still have a purpose. We provide snapshots as well but I don't see how large files are easier to download than small increasing changes.

[FFmpeg-user] avformat_open_input from an SDP string
Hi all, I have a question regarding avformat_open_input method, I saw that this method accepts URIs in addition to filename routes, then my question if I could use this function using an SDP string, in order to get the avformatcontext structure properly initialized. I want to initialize the avformatcontext given an SDP string (not an RTSP uri), is avfromat_open_input capable to do that? if not, is there any util i can use to achieve such goal. Thanks in advance for any comment. Regards, David ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user

Re: [FFmpeg-user] How to record audio and video from FaceTime HD Camera in OSX
Hi Roger, I will try the git master and update the thread. I also think there is something wrong in my command in OSX. When I run the below, it seems to recognize video device name as FaceTime HD Camera:audio=Built-in Microphone which is not correct and hence it could not find the video device. What is the command I need to use to specifically identify audio and video streams. In windows it is very clear and it works good with this command ( ffmpeg –f dshow –i video=”USB2.0 Camera”:audio=”Microphone (Realtek High Definition Audio)” -pix_fmt yuv420p out.mp4). How to do the same in OSX? Command I used in OSX $ ffmpeg -f avfoundation -i video=FaceTime HD Camera:audio=Built-in Microphone -r 29.97 -y out.mov Output [AVFoundation input device @ 0x7fc133c15700] Video device not found video=FaceTime HD Camera:audio=Built-in Microphone: Input/output error Thanks Jay On Sep 22, 2014, at 10:30 AM, Roger Pack rogerdpa...@gmail.com wrote: Could you try with git master [the patches were applied it seems, this weekend]?

Re: [FFmpeg-user] Extract DTS core from DTS-HD MA track
19.09.2014, 21:28, No Spam Please kirjoitti: All, I searched the mailing list archive and the last mention of extracting DTS core was around mid 2013. It was stated that it was a feature being worked on. Does the current version of ffmpeg support extracting the DTS core from a DTS-HD MA stream? If so, how does one invoke it using the command line? If not, are there other Linux based tools that would do the job? While splitting core is not directly supported (we need a new bitstream filter), you can still achieve it with a trick, by passing the stream through the S/PDIF IEC 61937 muxer and then demuxer, with HD disabled, e.g.: ffmpeg -i DTS-HD_MA.dts -f spdif -dtshd_rate 0 -acodec copy - | \ ffmpeg -i - -acodec copy DTS-Core.dts -- Anssi Hannula ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user

Re: [FFmpeg-user] ffmpeg read from UDP/Port
Hi Bill, I might be tempted to set both video and audio codec to copy, and save in a .TS file without -f at all. I did a look search on google about .ts files. My understanding is that, I can use videosnarf to convert a packet trace to .TS file. Is that the way you have in mind as well?

I am receiving H264 encoded packets through RTP with sample rate of 90,000, and I need to record these packets. The file format doesn't really matter at this point.

If that works you can capture the information and then play with it from the file.
