ffmep merge multiple (N) mono audio channels of a MXF video to multiple (M) stereo channels of MP4 video
13 février 2020, par LauraI have an MXF file with 16 audio mono streams and I need to recode it in a mp4 file with 2<=n<=16 channels merging input streams, e.g. input channels 1 and 2 on output channel 1 and 9 and 10 on output channel 2. This job will be done with ffmpeg. I read the documentation and found the amerge and amix filters that would be nice, but they output one channel only. Is there any solution for this problem ?
Thanks,
LauraFind below the output of ffprobe on mxf file :
