I have not fixed it now.I think that the driver maybe change Liumince
to BGRA when Upload texture,so it is very slow.

thanks for your response, yes, our frame is from a live camera, so it
changes dynamically.
as what you said, we passed YUV frame to the GPU, and do the YUV to
RGB convert in the GPU side (we used matrix-vector multiplication).
My questions are:
1) Does the GPU convert blocks the CPU?
2) if the
I need a little bit more of information before I can answer this
properly. Is your raw YUV frame being passed to the GPU as an OpenGL
ES texture? Is this YUV frame a static image, or it changes
dynamically (like, is it being captured from a live videocamera in
real time)?
