Subject: [RFC PATCH 00/12] Add support for HEVC and VP9 codecs in decoder 

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.

Thanks,
Dikshita
