Audio codec repkacement in a movie?

Is there a way (software) to replace an audio codec in a movie by another ??


ffmpeg (freeware) is the Swiss Army Knife of such things.  Although command line driven, it’s pretty straightforward.

You might also want such tools as tsmuxer (to demux and remux your video and audio streams) and mkvmerge (if you are making mkv containers).

tnank’s , I will look for these tools…
