Here's the output I get when I run the first command and lose video: % ffmpeg -i input.mkv -codec copy output.mp4įfmpeg version N-103075-g4c694093be-tessus Copyright (c) 2000-2021 the FFmpeg developersīuilt with Apple clang version 11.0.0 (clang-1100.0.33.17)Ĭonfiguration: -cc=/usr/bin/clang -prefix=/opt/ffmpeg -extra-version=tessus -enable-avisynth -enable-fontconfig -enable-gpl -enable-libaom -enable-libass -enable-libbluray -enable-libdav1d -enable-libfreetype -enable-libgsm -enable-libmodplug -enable-libmp3lame -enable-libmysofa -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-libopenh264 -enable-libopenjpeg -enable-libopus -enable-librubberband -enable-libshine -enable-libsnappy -enable-libsoxr -enable-libspeex -enable-libtheora -enable-libtwolame -enable-libvidstab -enable-libvmaf -enable-libvo-amrwbenc -enable-libvorbis -enable-libvpx -enable-libwebp -enable-libx264 -enable-libx265 -enable-libxavs -enable-libxvid -enable-libzimg -enable-libzmq -enable-libzvbi -enable-version3 -pkg-config-flags=-static -disable-ffplay I'm fine to use this for certain videos, but am not sure how to determine whether video re-encoding is needed or not (since I want to avoid it when possible). For this I'm use ffmpeg -i input.mkv -c:a copy output.mp4. If I only copy the audio codec, it seems to work fine, but takes much longer since video is re-encoded. Using -map 0 doesn't help, the examples I'm using only have one video stream and one audio stream. This works for most videos, but I find that the video stream gets lost for certain videos. The classic example I've found is ffmpeg -i input.mkv -codec copy output.mp4. I'm trying to come up with a robust script to handle all MKV -> MP4 video conversions.
