Hi, I'd like to know a simple things: is it possible to perform upsampling or downsampling directly on the GPU. I have a picture in YUV 422 format, and I would like to display it as a texture. I want to use the FBO to pass it as a texture. So in a first vertex and fragment shader I would like to upsample my picture from YUV422 to RGB, and pass it as a texture to a second vertex/fragment shader to display it.

Yes, this is possible.

Thanks,
How can I perform it??
