The Nvidia ION powered Intel Atom processor netbooks and nettops are the rage these days.
Affordable, lightweight and powerful graphics processor.
The Nvidia ION is actually an Intel Atom CPU coupled with a Nvidia 9400m graphics chipset.
Most linux distributions install fine on most netbooks and nettops. However, their default video player may not be optimized for the Nvidia ION chipsets. For HD video playback, without tweaking the parameters of the video player application, the end result may be lacklustre and the playback may even be not in sync or skipping frames.
To fully comprehend the power of video acceleration of the ION chipset with HD movies, SGLNX recommends MPLAYER.
MPlayer is present on most distribution’s repositories. To ensure smooth playback of HD movies (mkv, avi, mp4, etc), a slight tweak of the Mplayer’s config file is necessary.
To edit the config file, use these commands.
Open terminal
“sudo nano ~/.mplayer/config”
Insert these lines and remove any duplicate lines that may be present
vo=vdpau
vc=ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,ffh264vdpau,
#vo=xv
ao=alsa
#subcp=latin2
stop-xscreensaver=1
font=Arial
subfont-text-scale=3
subfont-osd-scale=3
Press “Control-X” to save the file.
The changes to the config file ensures that Mplayer will make use of VDPAU technology which is present on Nvidia’s GeForce 8800 series graphics card and above. For full compatibility of utilizing VDPAU acceleration, see here.
Next download a HD 1080p file from here.
Use Mplayer to playback this file and experience smooth HD playback with the ION chipset!
This guide would also apply for Nvidia graphics cards of the 9300 series and higher!
