Hello Adam,
I have updated the following branches with the versions I have used today:
Kernel:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream.git
branch: origin/HEVC_UAPI_V5 only one change in documentation vs version 4 but rebased in v5.18-rc1
Gstreamer:
https://gitlab.freedesktop.org/benjamin.gaignard1/gstreamer.git
branch: origin/benjamin.gaignard1/gstreamer-HEVC_aligned_with_kernel_5.15 updated on the latest GST main branch
I hope this will work fine this time.
Benjamin
