I installed ffmpeg, but I get this error when I use it. Input #0, matroska,webm, from 'input.mkv':ĭuration: 00:00:50.42, start: 0.I am trying to use ffmpeg on ubuntu 13.10 to convert AP3 to MP3? To convert all three audio tracks I tried this which runs without giving an error:įfmpeg -i input.mkv -c:v copy -c:a:1 pcm_s16be -c:a:2 pcm_s16be -c:a:3 pcm_s16be output.mkvīut the output file contains only one stereo track.įfmpeg gives the following information on the input.mkv file: ffmpeg version 4.4.1-3+b2 Copyright (c) 2000-2021 the FFmpeg developersĬonfiguration: -prefix=/usr -extra-version=3+b2 -toolchain=hardened -libdir=/usr/lib/x86_64-linux-gnu -incdir=/usr/include/x86_64-linux-gnu -arch=amd64 -enable-gpl -disable-stripping -enable-gnutls -enable-ladspa -enable-libaom -enable-libass -enable-libbluray -enable-libbs2b -enable-libcaca -enable-libcdio -enable-libcodec2 -enable-libdav1d -enable-libflite -enable-libfontconfig -enable-libfreetype -enable-libfribidi -enable-libgme -enable-libgsm -enable-libjack -enable-libmp3lame -enable-libmysofa -enable-libopenjpeg -enable-libopenmpt -enable-libopus -enable-libpulse -enable-librabbitmq -enable-librubberband -enable-libshine -enable-libsnappy -enable-libsoxr -enable-libspeex -enable-libsrt -enable-libssh -enable-libtheora -enable-libtwolame -enable-libvidstab -enable-libvorbis -enable-libvpx -enable-libwebp -enable-libx265 -enable-libxml2 -enable-libxvid -enable-libzimg -enable-libzmq -enable-libzvbi -enable-lv2 -enable-omx -enable-openal -enable-opencl -enable-opengl -enable-sdl2 -enable-pocketsphinx -enable-librsvg -enable-libmfx -enable-libdc1394 -enable-libdrm -enable-libiec61883 -enable-chromaprint -enable-frei0r -enable-libx264 -enable-shared The following command works but creates a video with only one stereo track:įfmpeg -i input.mkv -c:v copy -c:a pcm_s16be output.mkv I have mkv files with multitrack AAC audio which have to be converted to PCM-S16-BE.
