Seems related to http://bugs.python.org/issue19612, see http://stackoverflow.com/questions/23688492/oserror-errno-22-invalid-argument-in-subprocess. Maybe we can catch and ignore EINVAL from proc.communite()?

Side note: pre-#8256 approach on Windows produces perfectly playable mp4 files when interrupted with Ctrl+C.

jaimeMF · 2016-01-22T18:14:46Z

So previously on windows did you get the message Exiting normally, received signal 2. from ffmeg?

Does it mean that it also catches the Ctrl-C?

When it errors with UnavailableVideoError: [Errno 22] Invalid argument, is the video playable? (I guess yes, since ffmpeg exits with Exiting normally, received signal 2.)

Yes.

Yes, it's playable.

jaimeMF · 2016-01-23T13:55:36Z

If in windows subprocesses always receive the Ctrl-C, we could do:

if is_windows:
    proc.wait()
else:
    proc.communicate(b'q')

I would need to reboot the computer to load the Windows partition and make sure everything is working, so if someone could try it I would appreciate it.
