Comment (by Robert Mader):

 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.
