Comment (by gegegegege):

 Instead, the following code can call ffmpeg in c# and convert the full
 video. I'd like to ask you two more questions. One problem is that the
 print progress is supposed to be a regular log, not an error log. Why
 can't I use OutputDataReceived to receive it? The second problem is: how
 can I use ffmpeg to recognize that a mov file is an Apple space video,
 because there are other mov files that are not Apple space videos. Thank
 you very much.
