<pre>If I was to decide, I would suggest:
<span class="quote">>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.</span >
Reason:
- No application needs to be changed and all methods would be supported by this
hardware, too.
- Our workarounds + extra code to handle the env would also easily be 50+ lines
:-) and that per application (kodi, mpv, ...)
So @Christian happy for pointers on how to get it going.</pre>
