[Mesa-dev] VAAPI egl interop on radeon

Hi Jan,

I don't think we have implemented EGL interop on VA-API to this extend. 
All that is supported is exporting the handle of RGBA images, not 
directly decoded YUV data.

If you need decoding support with OpenGL/EGL interop on AMD hardware 
please use VDPAU instead.

Regards,
Christian.
