Sure. 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.
That could be a signal number incorrectly interpreted as a return code. That would make the signal probably SIGABRT, and therefore probably the sign of a failed assert. It is almost certain more diagnostic appears in ffmpeg's output. I do not know if Qt allows to capture it, but it would be unforgivable not to. Anyway, the ffmpeg-user mailing list is not the place to learn Qt programming, nor generic system programming. Regards, -- Nicolas George
