feat? remove audio track

[JustCauseWhyNot]

I thought it was possible to set audio_br: 0 to encode with no audio, but I get an error.

error

Traceback (most recent call last):

                          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^
KeyError: 'bit_rate'

Would it be possible to either have audio_br: 0 remove the audio, or add a flag to do ffmpeg -i Video -c copy -an Video_output that way there's no audio track at all?

I like it. I'll include this in an audio rework that I've been kickin' around sometime this summer.
