I am back since the issue with MOV file is not resolved. If you have any indication that I am wrong and that the file does contain information on how the audio channels should be interpreted, please elaborate! $ ffmpeg -i TorgashiShort.mov -vcodec copy -acodec copy -map 0:0 -map 0:1 out.mov The following simple command produces an output file with audio, but is probably not what you want (assuming the original sample does not contain two independent mono streams, but a stereo stream encoded as two singe-channel streams): $ ffmpeg -i TorgashiShort.mov -vcodec copy -filter_complex amerge -acodec pcm_s24le out.mov I guess the following is what most people would actually want: $ ffmpeg -i TorgashiShort.mov -vcodec copy -acodec copy -map 0:0 -map 0:1 -map 0:2 out.mov $ ffmpeg -i TorgashiShort.mov -vcodec copy -acodec copy -map 0 -dn out.mov Your sample contains an unusual channel layout, afaict it contains no information how the audio channels should be interpreted -(įFmpeg by default chooses the audio channel with the highest bit-rate, generally this is not a bad idea, but does not work for your sample. ![]()
