I'm currently porting the MPlayer media player to the Wii ( http://ronwarez.com/mplayerwii ) and for speed purposes, I'd like to display YUV textures on the screen instead of converting the YUV video source to RGB texture formats on every frame.

By grep-ing, I could see that there are some references to some YUV420p texture format, but I have no idea how to use it. Is there any source code or example available?

Thanks,

There is none, however, the TEV can be tricked into converting YUV to RGB. You would upload the Y, U and V channel into separate textures, and then combine them in a clever way using multiple texture coordinates and multitexturing.

I don't have a working code example though - I've just seen games doing this in Dolphin

Thanks for the tip, I guess I'm just gonna deal with RGB textures then
