So, the video track selection will implement like below:
Video decoder will send ALLOCATION query with caps when negotiation.
Video sink should propose video buffer based on query caps.
input-selector will send all sticky event (SEGMENT, CAPS...) to video sink
before push first buffer.

Video buffer pool only based on ALLOCATION query caps. CAPS event is used to
interpreted video sink input buffer. Video sink also need check input buffer
meta data to interpreted video buffer.

Is my understand right?
