Hi,
Some new aspects of HEVC reference pictures are a bit unclear to me, I hope someone can please explain. I have read some documentation in [1] and [2] but still unclear..
Assume Hierarchical B/P GOP structures are possible.
- Do P-frames still have only 1 reference frame ? (either a B/I frame) ? or can a P-frame have multiple (e.g. reference an I-frame and multiple B-frames) ?
- Similarly can B-frames have more than 2 reference frames ?
- Regarding the Reference Picture Set (RPS), if a B-picture has a RPS with 3 frames, then does it have to select the best 2 frames ? Are all the dependencies decided at the decoder side ?
- Is there a maximum limit to how many reference frames a picture can have ? (or is it specified by the side of the dependency picture buffer (DPB) size ?)
Many thanks
Rosh
