Recently, I found some perf issue when using
with 1080p images. I think it should be caused by the bandwidth to move data from GPU to system RAM.
Actually in our project, we need to encode the rendered frame with h264 and then stream to other place. And since NVIDIA GPU also supports hardware encoding, I am thinking if I use
then the rendered frame should be on the GPU and the GPU encoder should be able to use it directly. The question is can I get the memory pointer of GPU buffer from the
Texture object of Panda3D?
