FFprobe not working at all

[fluffy-critter]

It looks like the FFprobe mechanism is currently broken.

What's really strange about this (and I'm experiencing the same) is that if I take the command it says is being executed (in the debug output, and run it directly myself, it works fine!

[fluffy-critter]

Hm, might be something to do with TTY output on the ffmpeg binary? ffmpeg does some really weird stuff with terminal detection.

[dust333]

in class FFProbe in method probe replace

commands = [
            self._ffmpeg, '-y', '-i',
            self.file_name, '-f',
            'null', os.devnull]

with
commands = f"{self._ffmpeg} -y -i {self.file_name} -f null {os.devnull}"

as temporary solution

[amoh-godwin]

I have made a new release. I suspect that could be it. If it doesn't work I will try and fix it.

[solovieff]

@dust333 solution still seems to be the only way at the moment.
