Comment (by Balling):

 >The pixel-format / pixel-representation is not dictated by the codec and
 decoders are free to choose whatever format they see fit.

 H.264 spec describes a decoder only, not encoder and does in fact mandate
 pixel formats in which the overlaying of vector/raster primitives must
 happen. Also they may be 9 bits per pixel, you know? Whether as output or
 internally.


 >and what most HW decoders chose

 That is too simple. Until  Nvidia did not even support q>The pixel-format

 Okay at this point why not go to 10 years ago when this happened
