Hi,

it is currently not possible to get an opengl texture from gstreamer-1.0 yet (although it could be possible in the future). Is there some way we can take advantage of gstreamer now to accelerate video ?

do you suggest we ask gstreamer to send the buffer data as yuv, and perform the conversion ourselves. But so, how can we evaluate the performance win ?
