Sync by audio track?

[0xspringtime]

Would it be possible to add the ability to sync subs with a specific audio track if a video file has multiple tracks?

I know it's been a while since this has been asked, but I faced the same question and figured it out so wanted to share for anybody else.

Looks like the author added support for this a while back in b9450c7 but never cut a new release so it's not available if you install by cargo or from the releases page.

However, if you compile from source you will have the --index option which specifies an audio track index.
