So, as I reported the ubuntu package is based on mesa 10.1, and the same is on
debian git, thus the git hash seems to be 4a86465 (and line numbers reported on
these backports matches).

The full tree, with ubuntu patches applied, is available at
http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/mesa/trusty/files
(or bzr branch lp:ubuntu/mesa).

Mh, no I'm just getting this (on VLC):

VLC media player 2.1.2 Rincewind (revision 2.1.2-0-ga4c4876)
[0x15adaa8] main interface error: no suitable interface module
[0x13a9148] main libvlc: Running vlc with the default interface. Use 'cvlc' to
use vlc without interface.
libva info: VA-API version 0.35.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'vdpau'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/vdpau_drv_video.so

[0x7f4358c28e98] avcodec decoder: Using VA API version 0.35 for hardware

And pretty similar on mplayer (http://pastebin.ubuntu.com/7398928/), nothing
more kernel side.
