Replying to [comment:1 James]:
> I'm not sure i understand. Semi planar formats like NV12, P010 and such
are already supported. What is missing according to you?
If I'm not mistaken a *conversion* to NV12 or P010 is supported - but the
decoding always first creates yuv420/yuv420_10. The conversion, however,
requires a full copy. What I'm asking / suggesting is supporting direct
decoding to NV12 or P010.
I understand that this may require significant changes to performance-
critical code. The reason I think it's still worth investigating is that
those formats are supported by the vast majority of display controllers on
consumer devices and avoiding a full size copy - either on the CPU or GPU
- can thus increase playback performance, especially in scenarios where
memory bandwidth is the limiting factor.
