Hello, I want to encode my opengl rendering result into h264 with libva. I found the bottleneck is actually preparing the yuv image from the rgb rendering result. NVIDIA, for example, provides a way to directly encode an opengl texture map into video. I wonder if similar function exists with libva? I know it has some interoperability with egl, but I'm not sure if it is just for displaying decoded result?
Thank you, Shi
