Hi all, This patch series adds initial support for the HEVC(H.265) and VP9 codecs in iris decoder. The objective of this work is to extend the decoder's capabilities to handle HEVC and VP9 codec streams, including necessary format handling and buffer management. In addition, the series also includes a set of fixes to address issues identified during testing of these additional codecs. I'm sharing this series as an RFC because compliance and conformance testing are still in progress. While initial functional tests show positive results, I would appreciate early feedback on the design, implementation, and fixes before moving to a formal submission. I plan to submit a formal patch series after completing all compliance checks. Meanwhile, any feedback or suggestion to improve this work are very welcome.

I should be better to move patches 1, 2 & 3 at the end, after the patches adding support for specific hecv & h265 features, and please check that none of the patches breaks h264 at any time to keep bisectability. Neil Neil
