glTexDirectVIVMap and YUV420p

[ortogonal]

Hi!
I'm using the VPU to decode HD movie and trying to display the movie by using glTexDirectVIVMap. I have a simple question, and it may have a really simple answer due to my little knowledge about video encoding. But all the sample HD movies I found uses YUV420P colospace and that is not a format that is supportet by glTexDirectVIVMap. How can I solve this? Is it possible to do somethin in the IPU before and make the color space conversion there, or is it possible to write a fragment shader that makes the color conversion.

The result I end up with is a really smooth playing movie but with wrong colors.

Thanks!

Erik

Hi Erik

colospace conversion can be done by both IPU and GPU,

examples can be found below
