[FFmpeg-devel] [PATCH] av1dec: update hwaccel decode_params on AV1_OBU_SEQUENCE_HEADER

[FFmpeg-devel] [PATCH] av1dec: update hwaccel decode_params on AV1_OBU_SEQUENCE_HEADER

[Lynne]

Previously, the callback was only called on init. This makes it
get called on every frame.

We should switch to VK_KHR_video_maintenance2 and provide all params
upfront, but almost nothing supports it yet.
