Hey guys, Suppose I have a media file composed by 1 video stream and 2 audio streams (both AAC). Is it possible to add metadata at the stream level, for each of the two audio?
Here is the probe of the media in question: ffprobe version 3.1.1-tessus Copyright (c) 2007-2016 the FFmpeg developers built with Apple LLVM version 7.3.0 (clang-703.0.31) configuration: --prefix=/Users/adinapoli/ffmpeg-3.1.1/ffmpeg_build --extra-cflags=-I/Users/adinapoli/ffmpeg-3.1.1/ffmpeg_build/include --extra-ldflags=-L/Users/adinapoli/ffmpeg-3.1.1/ffmpeg_build/lib --bindir=/Users/adinapoli/ffmpeg-3.1.1/bin --extra-libs=-ldl --as=yasm --disable-debug --disable-ffplay --disable-indev=qtkit --disable-indev=x11grab_xcb --enable-avisynth --enable-avresample --enable-fontconfig --enable-frei0r --enable-gpl --enable-libmp3lame --enable-libx264 --enable-libxvid --enable-nonfree --enable-pthreads --enable-shared --enable-vda --enable-version3 --extra-version=tessus libavutil 55. 28.100 / 55. 28.100 libavcodec 57. 48.101 / 57. 48.101 libavformat 57. 41.100 / 57. 41.100 libavdevice 57. 0.101 / 57. 0.101 libavfilter 6. 47.100 / 6. 47.100 libavresample 3. 0. 0 / 3. 0. 0 libswscale 4. 1.100 / 4. 1.100 libswresample 2. 1.100 / 2. 1.100 libpostproc 54. 0.100 / 54. 0.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'multi.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf57.41.100 Duration: 00:05:00.05, start: 0.000000, bitrate: 3799 kb/s Stream #0:0(und): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 2560x720 [SAR 1:1 DAR 32:9], 3664 kb/s, 29.97 fps, 29.97 tbr, 11988 tbn, 59.94 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 64 kb/s (default) Metadata: handler_name : SoundHandler Stream #0:2(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 64 kb/s Metadata: handler_name : SoundHandler Here is the command I tried: ffmpeg-3.1.1 -i multi.mp4 -y -map 0:v -map 0:a -codec copy -metadata:s:a:0 title="Foo" -metadata:s:a:1 title="bar" multi2.mp4 But the metadata does not show in the output probe: ffprobe version 3.1.1-tessus Copyright (c) 2007-2016 the FFmpeg developers built with Apple LLVM version 7.3.0 (clang-703.0.31) configuration: --prefix=/Users/adinapoli/ffmpeg-3.1.1/ffmpeg_build --extra-cflags=-I/Users/adinapoli/ffmpeg-3.1.1/ffmpeg_build/include --extra-ldflags=-L/Users/adinapoli/ffmpeg-3.1.1/ffmpeg_build/lib --bindir=/Users/adinapoli/ffmpeg-3.1.1/bin --extra-libs=-ldl --as=yasm --disable-debug --disable-ffplay --disable-indev=qtkit --disable-indev=x11grab_xcb --enable-avisynth --enable-avresample --enable-fontconfig --enable-frei0r --enable-gpl --enable-libmp3lame --enable-libx264 --enable-libxvid --enable-nonfree --enable-pthreads --enable-shared --enable-vda --enable-version3 --extra-version=tessus libavutil 55. 28.100 / 55. 28.100 libavcodec 57. 48.101 / 57. 48.101 libavformat 57. 41.100 / 57. 41.100 libavdevice 57. 0.101 / 57. 0.101 libavfilter 6. 47.100 / 6. 47.100 libavresample 3. 0. 0 / 3. 0. 0 libswscale 4. 1.100 / 4. 1.100 libswresample 2. 1.100 / 2. 1.100 libpostproc 54. 0.100 / 54. 0.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'multi2.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf57.41.100 Duration: 00:05:00.08, start: 0.000000, bitrate: 3799 kb/s Stream #0:0(und): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 2560x720 [SAR 1:1 DAR 32:9], 3664 kb/s, 29.97 fps, 29.97 tbr, 11988 tbn, 59.94 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 64 kb/s (default) Metadata: handler_name : SoundHandler Stream #0:2(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 64 kb/s Metadata: handler_name : SoundHandler What am I doing wrong? Is this even possible or am I flogging a dead horse? Thanks in advance!
