This guide is for people getting stuttery or jerky playback of videos, full screen or not, using Ubunutu 14.x or derivatives ( Linux Mint 17.x etc ) and using an AMD video card
Firstly make sure you are using the propriety drivers:
sudo apt-get install fglrx-updates fglrx-amdcccle-updates
and reboot
Install vainfo:
sudo apt-get install vainfo
Now look at the vainfo output, it will probably look like:
# sudo vainfo
error: XDG_RUNTIME_DIR not set in the environment.
libva info: VA-API version 0.35.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
So your missing the link to the acceleration driver. Do:
sudo ln -s /usr/lib/libXvBAW.so.1.0 /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so
Now your vainfo should look like:
# sudo vainfo
error: XDG_RUNTIME_DIR not set in the environment.
libva info: VA-API version 0.35.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so
libva info: Found init function __vaDriverInit_0_33
libva info: va_openDriver() returns 0
vainfo: VA-API version: 0.35 (libva 1.3.0)
vainfo: Driver version: AMD MMD 1.0
vainfo: Supported profile and entrypoints

Your all set. Video should now play smoothly. IF your still experiencing poor video and you are using Totem player – read on.
I don’t find Totem enough for my needs as a video player so I suggest installing mplayer/smplayer:
sudo apt-get install mplayer smplayer
You can make this your default player for video files from the right click menu of any of your videos.
Some also prefer VLC player.
