Passthrough Audio based on rules?

Feature details

Hi, I love VidCoder, I've been using the beta for as long as I can remember. I think it'd be great if the audio encode/passthrough options could be automatically adapted based on user rules.

For example:

If source audio is 5.1 with a bitrate greater than 640kbps, encode to AAC 2.0 192kbps

or

If source audio is 2.0 and bitrate is less than or equal to 192kbps, passthrough, otherwise encode to X

or

If source audio is 5.1 AAC, encode to 5.1 AC3, else passthrough

These rule would make audio encoding/passthrough much more flexible.

It sounds like it would have some utility, though it would be expensive to implement. It's something I would entertain taking a pull request for, but I likely wouldn't have time to implement for a while.
