I double checked the branches.
Kernel:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream.git
branch: origin/HEVC_UAPI_V4
Gstreamer:
https://gitlab.freedesktop.org/benjamin.gaignard1/gstreamer.git
branch: origin/benjamin.gaignard1/gstreamer-HEVC_aligned_with_kernel_5.15
I am still not able to run h.265/HEVC tests.
