But this is already doable. Just write the shader code for it. That's the whole point of having shaders to begin with; you can do almost anything you want with them. It means that you aren't limited by the capabilities of the hardware.And I want only use what can already make the hardware when it decode an MPEG video streams into a window ... but want that the decoding is directly make into one OpenGL texture and not in a window ... it's really as difficult as this to understand ???
There is no reason for them to add hardcoded features for things that you can do with shaders unless they are generally useful and are performance bottlenecks for most users.
