I don't understand QProcess (yet, or anymore), so I have no idea what to debug. I don't know what to make of the return code 6 either. it doesn't come from ffmpeg, as far as I can tell from the latter's source. ffmpeg isn't stuck at that point, it just terminates, right? > > If ffmpeg crashes, that's bad.

Well, if MacOS happens to have gdb, it would work by replacing your ffmpeg command line with: $ gdb -ex r -ex bt --args ffmpeg [further command line options] i.e. prepending gdb. The ffmpeg binary should not be stripped for this to work properly. MacOS may have lldb instead of gdb, but I have no experience in operating that. > > Do you need to run it in bash?

I trust you. I was just speculating.
