This patch is for RFC:
Did some tests on some of the encoders and find some encoders
not suitable for now, hence didn't declare the caps for them:
1. libx264: seems have frame drop.
2. hardware encoders like vaapi: failed.
Hence before we got all encoders supported, I'd prefer to declare
caps for specific encoder and add the enhancement step by step.
