Comment 0 for bug 1652466

What is the problem:
Totem can't play videos if gstreamer1.0-vaapi is installed on Gallium graphics in Xenial because mesa-va-drivers is not installed as a dependency of va-driver-all.

Here is the dependency chain in Xenial:
gstreamer1.0-vaapi Depends on libva1
libva1 Recommends va-driver-all
va-driver-all Depends on i965-va-driver vdpau-va-driver (no mesa-va-drivers!)

Here is the terminal output of Totem (with gstreamer1.0-vaapi installed and no mesa-va-drivers):
:~$ totem
Stream with high frequencies VQ coding
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/radeonsi_drv_video.so
libva info: va_openDriver() returns -1
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/gallium_drv_video.so
libva info: va_openDriver() returns -1
libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns 0

When mesa-va-drivers is installed, Totem plays videos just fine.

This is fixed in version 1.7.0-2 in Debian and Yakkety.
libva (1.7.0-2) unstable; urgency=medium

  * debian/control:
    - Add mesa-va-drivers as alternative to Depends of va-driver-all.
    - Bump Standards-Versions.
