Hi everyone :) I'm trying to create .mp4 files with uncompressed, linear PCM for audio in it.
I know for quite a while already that FFmpeg doesn't allow that: > [mp4 @ 0x50cc780] Could not find tag for codec pcm_s16le in stream #0, codec not currently supported in container > Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument In my research a few years ago I stumbled over a few sources saying that MP4 specs didn't allow LPCM for audio [1,2,3]. However, I know that some (Sony) video cameras do produce PCM in .mp4 container, and Wikipedia also lists LPCM as supported audio codec [4] in MP4. Experience has shown that "if FFmpeg can't/won't do it - there's a good reason" :) May I ask what that reason is? Thank you very much in advance for any insights, Peter B. # Links [1] https://stackoverflow.com/questions/17651975/unable-to-store-pcm-audio-in-mp4-container-file [2] https://forum.doom9.org/archive/index.php/t-140877.html [3] https://stackoverflow.com/questions/38309120/ffmpeg-mov-to-mp4-error-could-not-write-header-for-output-file-0-incorrect-co [4] https://en.wikipedia.org/wiki/Comparison_of_video_container_formats#Audio_formats_supported _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
