What kind of logic is that? If there's no explanation how do you know that there are no other solutions?

I'm really just paraphrasing Denis at the last workshop. The core should not have to handle every idiosyncrasies of every demuxer. That's demuxers' job. Even more so if it also affects not just the core but user interfaces and LibVLC APIs.

If you need to generalise programs to handle qualities and angles, do it. That would actually remove some code in the ES output even.

Frankly, I don't think that I (or Denis or anybody else) should have to argue about  clean design and abstraction. That should be the default.
