Thanks for the question, I haven't thought for avc, yet.

I guess we have few options:

1. introduce hdr10-ctrls.h, common control IDs
2. duplicate structures and control IDs in hevc/h264-ctrls.h
3. common structures and separate control IDs for avc and hevc
4. another option?

I'd prefer option 1. We could extend later option 1 with hdr10+.
