Use ffprobe to add sane defaults

Opened this issue 3 months ago · 1 comments

Eg; we're not probing the input so if we use a 720p input file and specify 1080p, it'll upscale for no reason. We should ffprobe the input files in order to adjust the output streams accordingly.

Now that we have support for channels in audio, these should be optional. The same goes for language, we'd rather read it from ffprobe by looping over the different streams. If there's metadata or channels num in the input metadata, we'd rather pick that one.

Default to 2 channels num, and language equals "unk" when it could not be extracted. We don't want to be too harsh on throwing exceptions when input metadata is not available.
