Hi Haihao,

This is good to know. I'll check it out.

Thanks,
Cyril

With the latest version of libva, vaCreateSurfaceGLX fails all the time when I set OpenGL to 3.1 or above. If I set it to 3.0, then it doesn't fail, and everything works correctly. I downloaded the sources of libva and it fails when checking for GL extensions because of the use of glGetString(GL_EXTENSIONS) which is deprecated. Is that something you guys can fix so that it is available in the latest version? I have implemented a fix on my end (which I can send if you'd like) so it is not a big issue but I'd rather use the official version.
