Jonathan, this is what I was afraid of. Do you have any rough estimates when/if we can expect updated driver for PSB? I know it was expected for Moblin 2.1, but we are now in 2010 and still no news about new driver. Frankly I was bit surprised that vaCreateSurfaceGLX/vaCopySurfaceGLX do not work with PSB. Both OpenGL textures and vaSurfaces are internally just porinters to blocks of memory supervised by graphic chip, so I thought that vaSurface should be available as OpenGL texture straightahead, only thing needed is some binding between vaSurfaceID and OpenGL texture ID. > Gwenole had some comments on the various ways of doing UI recently: > http://lists.freedesktop.org/archives/libva/2010-January/000140.html Yes, I saw that post. Unfortunately we have quite advanced OpenGL 2D GUI, and with subpictures all I can get is some overlays onto rendered video surfaces, this is not enough as I got quite opposite scenario here with multiple video streams (4-9) embedded into semi-transparent OpenGL GUI (menus, lists, widgets). Regular version uses OpenGL textures fed by glTexImage2D with data from software codec. Now I was about port the decoding part to VA API, but I am stuck.
