Hello!
I am trying to convert a quicktime reference mov file exported from Avid MC 8.4.5. I am using the following conversion command: ffmpeg -threads 0 -enable_drefs 1 -use_absolute_path 1 -i testseq.mov -strict -2 -pix_fmt yuv420p test.mp4 -y After hardly managing to get ffmpeg to reach all the referenced files, here is the problem. In the converted mp4 the cuts (timecodes where source media is changing in the sequence) gets through allright, but only on source clip is used as source. The other source clips are just ignored. Is this behavior "normal". That's it, this is all that is implemented so fat in ffmpeg or: 1. I sould look for an updated version of the software 2. I am missing something out 3. I am doing something wrong Here is the command with the output during conversion. After conversion no error messages are displayed. root@mediasync-ubuntu:/share# ffmpeg -threads 0 -enable_drefs 1 -use_absolute_path 1 -i test\ seq.mov -strict -2 -pix_fmt yuv420p test.mp4 -y ffmpeg version 2.8.11-0ubuntu0.16.04.1 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.4) 20160609 configuration: --prefix=/usr --extra-version=0ubuntu0.16.04.1 --build-suffix=-ffmpeg --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --cc=cc --cxx=g++ --enable-gpl --enable-shared --disable-stripping --disable-decoder=libopenjpeg --disable-decoder=libschroedinger --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librtmp --enable-libschroedinger --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzvbi --enable-openal --enable-opengl --enable-x11grab --enable-libdc1394 --enable-libiec61883 --enable-libzmq --enable-frei0r --enable-libx264 --enable-libopencv libavutil 54. 31.100 / 54. 31.100 libavcodec 56. 60.100 / 56. 60.100 libavformat 56. 40.101 / 56. 40.101 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 40.101 / 5. 40.101 libavresample 2. 1. 0 / 2. 1. 0 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.101 / 1. 2.101 libpostproc 53. 3.100 / 53. 3.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x1c56520] Using absolute path on user request, this is a possible security issue [dnxhd @ 0x1c59160] frame size changed: 1920x1080 -> 1440x1080 Guessed Channel Layout for Input Stream #0.0 : stereo Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test seq.mov': Metadata: major_brand : qt minor_version : 537199360 compatible_brands: qt creation_time : 2017-05-25 19:04:15 comment : Source ID = 060a2b340101010101010f00-13-00-00-00-{59271bed-5179-0018-060e2b347f7f2a80} comment-eng : Source ID = 060a2b340101010101010f00-13-00-00-00-{59271bed-5179-0018-060e2b347f7f2a80} timecode : 01:00:00:00 Duration: 00:00:44.48, start: 0.000000, bitrate: 1 kb/s Stream #0:0(eng): Audio: pcm_s16be (twos / 0x736F7774), 48000 Hz, 2 channels, s16, 1536 kb/s (default) Metadata: creation_time : 2017-05-25 19:04:16 handler_name : Apple Alias Data Handler Stream #0:1(eng): Video: dnxhd (AVdn / 0x6E645641), yuv422p(pc), 1440x1080 [SAR 4:3 DAR 16:9], 83558 kb/s, 25 fps, 25 tbr, 2500 tbn, 2500 tbc (default) Metadata: creation_time : 2017-05-25 19:04:16 handler_name : Apple Alias Data Handler encoder : Avid DNxHD Codec Stream #0:2(eng): Data: none (tmcd / 0x64636D74) (default) Metadata: creation_time : 2017-05-25 19:04:16 handler_name : Apple Alias Data Handler timecode : 01:00:00:00 [libx264 @ 0x1c8b780] using SAR=4/3 [libx264 @ 0x1c8b780] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 [libx264 @ 0x1c8b780] profile High, level 4.0 [libx264 @ 0x1c8b780] 264 -
