As some of you undoubtedly know The EPIA M10000 supports hardware assisted Mpeg-2 decoding via the CLE266 chip. The generic VESA driver included with DSL works with the CLE266 but doesn't support any of its advanced features.
A dramatic improvement in both video quality and playback performance can be achieved by using a properly patched Kernel, XFree 4.4, the Unichrome Driver and the XvMC library. I know of no Live CD that fully utilizes the Mpeg features of the EPIA, but Freepia comes very close. I’d love to achieve the same results with DSL, but the modifications listed above exceed my abilities. Any takers?
Here are a few tips for achieving the best Mpeg-2 playback possible with the dsl-1.1.iso.
Install mplayer.dsl from myDSL Mutlimedia Extensions
Using Xvesa reduce the X Windows desktop size and set the bit depth to 24. I am watching NTSC videos so I set my desktop to 640x480x24
Maximize your video memory by choosing a simplified the X Windows style (one without a background image).
The following command does a fair job of playing back most of my Mpeg files.
mplayer –vo x11 –framedrop –fs filename.mpg
Because I’m usually playing back files encoded at a resolution of 740x480 and my desktop is only 640x480 a portion of the right side of the screen is cropped off unless I scale the video.
mplayer –vo x11 –framedrop –fs –zoom –xy 640 filename.mpg
It’s often a tossup between using a 800x600x24 desktop or using software scaling. Try both and see what works best for you.
You can also use nice to modify the priority of mplayer. For this to work you’ll need to be root.
sudo su
nice -n -20 mplayer –vo x11 –framedrop –fs –zoom –xy 640 filename.mpg
Kudos to everyone involved in making Damn Small Linux THE BEST small distribution available.
