Install Nvidia Experimental 310 Drivers

January 2013: the current Ubuntu driver 304 is dated August 2012.

The list of 5 installed packages is...

nvidia-common
nvidia-current
nvidia-current-updates
nvidia-settings
nvidia-settings-updates

To install the latest and greatest 310 driver from November, follow these commands...

sudo apt-get remove nvidia*
sudo apt-get install nvidia-experimental-310
sudo reboot

This will install just 2 packages...

nvidia-experimental-310
nvidia-settings-experimental-310 

The difference is very nice indeed. :-)

Fix Tearing and Stuttering

http://www.mythtv.org/wiki/VDPAU#Tearing.2FStuttering

could not write bytes: Broken pipe

This appears to be an NVIDIA issue and prevents booting in to a graphical environment:

sudo apt-get update
sudo apt-get purge nvidia-*
sudo apt-get install nvidia-current-updates

The above sould repair/replace the drivers, however if your reboot and still have go GUI and/or a password entry loop:

sudo mv .Xauthority .XauthorityOld
sudo reboot

PureVideo

Nvidia PureVideo is a hardware feature designed to offload video decoding processes and video post-processing from a computer's CPU hardware to NVIDIA's GPU hardware series GeForce 6, GeForce 7, GeForce 8, GeForce 9, GeForce 200, GeForce 400, GeForce 500 ; GeForce M series (formerly known as GeForce Go); and Nvidia Quadro series. PureVideo is designed to work with media playback software. NVIDIA's device drivers for Windows XP, Windows Vista and Windows 7 are PureVideo-enabled; with the appropriate (PureVideo-enabled) application software, the NVIDIA driver will automatically use whatever hardware-acceleration is available on the NVIDIA display-adapter.

All software HD DVD/Blu-ray players, as well as most software DVD players, are PureVideo-enabled. Microsoft's Windows Media Player and Windows Media Center also supports NVIDIA's PureVideo technology. NVIDIA also sells its own PureVideo decoder software (which is a source of confusion, as NVIDIA's decoder is not required and not used by third-party players), which serves as a DVD player with advanced post-processing capabilities. The degree of PureVideo's capabilities varies by generation.

On 2008-11-14 NVIDIA released a beta version of a closed-source device driver and open-source API called VDPAU (Video Decode and Presentation API for Unix) with PureVideo support for Linux, FreeBSD and Solaris.

See - http://en.wikipedia.org/wiki/Nvidia_PureVideo

VDPAU

VDPAU (Video Decode and Presentation API for Unix) is an open source library (libvdpau) and API originally designed by NVIDIA for its GeForce 8 series and later GPU hardware, targeted at the X Window System on Unix-based operating systems (including Linux, FreeBSD, and Solaris). This VDPAU API allows video programs to offload portions of the video decoding process and video post-processing to the GPU video-hardware.

Examples

Here are examples of software using VDPAU.

Mplayer

The error when you DO NOT have one of these new video cards...

[vdpau] Error when calling vdp_device_create_x11: 1

How to use mplayer and vdpau with an ffmpeg x264 encoded video...

mplayer -vo vdpau -vc ffh264vdpau video.avi

You will then see this output in the console...

Forced video codec: ffh264vdpau
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffh264vdpau] vfm: ffmpeg (FFmpeg H.264 (VDPAU))
[VD_FFMPEG] Trying pixfmt=0.
Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.
VO: [vdpau] 1280x720 => 1280x720 H.264 VDPAU acceleration 
[VD_FFMPEG] XVMC-accelerated MPEG-2.

...and the display is silky smooth, with only about 5% CPU usage :-) and no fans needed!

HandBrake

The error when you DO NOT have one of these new video cards...

No accelerated IMDCT transform found
