Zaurus - pdaXrom / Playing video in 320x240 fullscreen
« on: April 20, 2004, 06:19:17 pm »
Thanks for the tip, I\'ll do it. I\'ve found out that the width and height in the w100 vidix driver are sent to 480 and 640 respectively. But mplayer is comparing this to the X width and height which is 640 and 480. Because of the difference the vidix driver is failing. If I rotate the screen to portrait mode and run the xvidix or console vidix then the video plays using the direct access to the video memory.

I modified the driver to switch the 640 and 480 around and video plays ok using vidix in normal vga now. Issues at the moment are the video is not overlaying the mplayer window. For some reason the overlay is rotated 90 degrees out from the mplayer window. It looks like the x and y coordinates passed to the ATI funtions have 0,0 at the lower left of the screen in landscape mode. I\'m not sure what to do about that and the 640x480 issue.

I\'m also unable to get hardware scaling working at the moment so full screen doesn\'t work. The issue with that is the internal memory for the ati w100 only handles 320x240. Using external memory for 640x480 works but the video plays \'wavey\' and corrupted. I suspect something is wrong with the driver code there and would need to investigate.

qvga still doesn\'t work - probably the memory offsets are different for writing to the screen in that mode. More playing needed. Still it looks promising for using the ATI acceleration functions to get better performance out of the video.

I\'ve recompiled the latest CVS mplayer with the w100 ATI vidix driver from ( to try and get w100 support. Using the vidix driver from the console mplayer tells me I\'m in an unsupported resolution (640x480). I switch to QVGA using the command line above and the fb.modes file and it runs. Unfortunately no image. I get a white screen with a purple square about the size of the mpg file I\'m trying to play to test it out. When I quit out I\'m back to the garbled qvga terminal.

Has anyone seen the white screen with purple square before? Any ideas what I could look at to fix it?

If you want to try it the ipk is at:

You\'ll need libsdl and libmad installed. I also haven\'t tuned what drivers to include/not include. The common line to try is:

  mplayer -vo fbdev:vidix -fbmode qvga -vm -nosound mympg.mpg

I\'m using nosound for testing. I haven\'t tested \'mad\' support but sdl support for sound works fine. You could also try \'X\' vidix support:

  mplayer -vo xvidix -fbmode qvga -vm -nosound mympg.mpg

But that\'s even more broken I think.

I\'ve compiled wxWindows for the pdaxrom. It and a few of the example programs are available at:

Found this page with a newer version of mplayer with support for the Zaurus graphics chip (apparently). I haven\'t tried it though:

Where did you get the v1.00 mplayer with the ATI code from? Is there an IPK available?

I have ported some beaming utilties at:

I use these for transferring to/from my phone quite a bit and it works well.

Zaurus - pdaXrom / SD /mnt/card has become read-only
« on: March 20, 2004, 06:15:57 pm »
If that doesn\'t work and your card is formatted with ext2  unmount and fsck the file system (basically checks for internal errors):

umount /mnt/card
e2fsck /dev/mmcda1
mount /mnt/card

The development environment for cross compilation is pretty good and not too hard to use. The older zgcc image for running on the machine works fine too. That said, I\'m looking forward to seeing what the new development environment is too.

The buffalo card still requires the patch .ipk in pdaxrom 1.0.0.

Zaurus - pdaXrom / python version in pdaxrom 1.0?

The pdaxrom doesn\'t have \'find\' or \'python\' or pygtk preinstalled.

That\'s great! I\'m looking forward to trying it.

Zaurus - pdaXrom / IoVM for pdaxrom available

I\'m working on getting IoServer compiled so we get socket support, etc. Hopefully it won\'t be long.

I\'ve compiled IoVM, an interpreter for a prototype-based object system language, combining ideas from Newton Script, Self, etc. You can download it from:

With regards to the buglist, an nice option would be to be able to add comments to a bug. For example, bug number (5), being required for mplayer. This library is supplied with gqview. Install that and mplayer works.

I like the battery applet changes. Instead of the usual 4 steps of \'full\', \'nearly empty\', \'really nearly empty\' and \'empty\' you get a correct reading at 1% or so intervals. Great!
