That would be a great achievement= ! Thanks for working on Hantro G2 support! As the initial author of the HEVC API, it definitely does not feel ready to be destaged. The API has lots of issues and limitation and I think signific= ant work is still needed. This initial implementation was kind of a proof of concept for simple cases.
