[FFmpeg-devel] video corruption using h264 hw decoders

Sorry for having not set the headers correctly and the messages don't show
up as response. I am not receiving emails on this thread and can't just simply
reply.

With GL_NV_vdpau_interop vdpau exposes video surfaces (you call them internal)
and output surface to open gl. Those can be directly mapped to gl textures.
If e.g. de.interlacing is not required, the mixer can be bypassed and a video
surfaces can be directly rendered by open gl.
Both methods, interop and mixer, provide the use of a source rectangle for
cropping.
