from Alex Deucher
You can't really enable a GL extension if there is not support for the entire thing. Early versions of UVD did not support field based output. The extension provides access to both the raw decoded video surfaces (field based) and the vdpau processed output surface (frame based). I think by default kodi only uses the vdapu processed output which is the part that is supported. Changing the kodi settings may require the full extension which will not work. I guess there are 3 options: 1. Force the option but limit it to cases where you are only using the output surface via the interop extension. This works today. 2. Add an extra step to the drivers using shaders to split the frame up into separate fields in vlVdpVideoSurfaceGallium (src/gallium/state_trackers/vdpau/surface.c) for chips that don't support field based decode. This adds an extra copy and someone needs to write the code. With that done, the extension can be enabled on all asics. 3. Write a new simplified GL/VDPAU interop extension that only supports interop with output surfaces. This extension could be enabled on all asics.
