I am using the latest Xorg, Mesa from git and the Linux 4.7.2 kernel. I
have an Nvdia NVA8 chipset[ion] with xorg setup to use the latest
nouveau driver and it also supposed vdpau and I have the firmware
required to get video acceleration. When attempting to playback video
with mplayer using vdpau, I noticed the video playback freezes after a
few frames when trying to playing video using vdpau. The system doesn't
freezes but just the video cannot seem to continue playing since the
video playback. I tried different kernels and Mesa versions and it
didn't make any issue. When I attempt to recompile Xorg from git, I
found the following commit on 2016-07-21 breaks the vdpau playback for me.

Anyone else experience this issue? It seems if I compile with the
previous commit [8f1edf4bd3a1f050ce9eeb5eac45dd1a8f7a6d5e], everything
works perfectly.
