ffmpeg merge multiple (N) mono audio channels of a MXF video to multiple (M) stereo channels of MP4 video
14 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 :

FFMPEG, Creating an MPEG-DASH stream with existing inputs
10 septembre 2019, par kitenseiI am trying to generating a
DASH .mpdfile from multiple inputs (2 videos, 1 audio) without any success..What I’d like to do it’s simple getting the streams and create an mpd file without any re encoding since I’ve already my sources ready.
The output seems to work in rxplayer, but I do get a lot of errors (see log below).
Here are my 3 sources (taken from http://dash-mse-test.appspot.com/media.html) :
