Keeping track of audio stream when none exists

Created by: ingles98

Hey!

So i am keeping track of the audio stream like i = ffmpeg.input(self.video_input, **self.args) self.audio_input = i["a"] The issue is when the video doesn't have a audio stream... What happens is that ffmpeg will throw Stream map '0:a' matches no streams. To ignore this, add a trailing '?' to the map. In the end where I concat my audio input back in for the output.

The program i am making should be able to accept any video files of any format in and so far it is doing its job, except when the audio stream is non existent heh. Is it possible to add the trail to the thing ?

The concat is done here ffmpeg.output(stream, self.audio_input, self.output, **self.args)
