10 months ago The argument "path/source/video.mp4", is wrong, it needs to be absolute, "/path/source/video.mp4". This is not a Go bug.

}Not the path problem, It also appears to the ffmpeg-go lib. That lib also use exec command lib.

10 months ago @GostGrimmy what I'd check for first — try dropping quoting from your arguments, use
"-adaptation_sets", "id=0,streams=v id=1,streams=a",instead of the current
"-adaptation_sets", "\"id=0,streams=v id=1,streams=a\"",You don't need to quote things as in shell, ffmpeg in your case is handed the quoted string, so I suspect it fails on parsing it.
