[FFmpeg-user] Fatal errors

Yes, I want to be sure that the output file was successfully generated and that there is no risk that it is anyhow corrupted. I don't know much about ffmpeg, and I assume that it can exit with code 0 but at the same time write to the output some errors that may (or may not) affect a generated video. This is why I used word risk.

I am using ffmpeg.exe to convert video to mp4 format (among other things). I don't remember why but (I assume) there was a reason why I decided to analyse ffmpeg output for errors (maybe exit code hasn't worked for me in some cases).
So what I want to do is to detect when ffmpeg fails to create completely correct converted file.
