Comment 11 for bug 1416005

Totem still fails for me to play almost anything (but something works, strange) on xenial with vaapi.
When it does not work, it shows the video length, start playing the first seconds with black screen, and then stops there.
On the console I see

libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_0_39
libva info: va_openDriver() returns 0

(totem:4934): Cogl-WARNING **: driver/gl/cogl-buffer-gl.c:93: GL error (1280): Invalid enumeration value
