ultracam distorted image
Using Kernel 2.4.19, IBM UltraPort Camera (I), ultracam, usbvideo, videodev compiled in and as modules (neither works). . .
I looked at the MAINTAINERS file, and this device is not even listed so I have no options left but to bug you (sorry).
when using the gqcam app, I get a distorted image (a sample can be found on http://home.attbi.com/~gnuman/webcam.html ) and the error ioctl (VIDIOCSWIN): Invalid argument
which seems to point to autoscaling brightness. . .
the image looks like it is not synching properly and the brightness does not matter that much to me.
When I use the CVS usbvideo package (the module is named ultradrv instead of ultracam), I get a smaller black screen and "error reading image. . ."
when using the 2.5.45 kernel, I get a white one, with the same results.
Having done a Google search on UltraPort Camera and Linux, as well as one on the error, I found Karl Gutwins page (where I got the CVS package), and quite a bit of discussion that stopped a over a year ago, about things not working. I found no one that could give me any more advice on how to get this working for me. I get the same results when I'm using the camera from the ultraport or USB.
hasciicam works, but that is useless to me as I need to use this with a webcam and several other v4l applications. I have run out of places to look for information and clues, and I cannot find the author for the kernel driver (not listed in the code, or the maintainers file). It seems to me that *someone* must have gotten this running, but they seem to want to keep that info to themselves?
Please reply to me personally as well as the list, to ensure that I see any response.
Thank you for all your efforts in making Linux so great!
PS: is there any work being done on a DRM for the S3 Savage IX chipset? That is the only other thing not working right on my laptop.

Sanjay [email protected] I'm pretty sure that for a 747, IFR actually doesn't mean "I Follow Roads."

It always was experimental, as I recall. Karl Gutwin is the author. See http://www.linux-usb.org/

[email protected] is a more appropriate forum.

It's better than most :-) You probably have a different version of the camera, with a different firmware, hardware or sensor.

Indeed, the decoder of the camera datastream is not working. Everything else, past the decoder, seems to work.

Check the dates, maybe in-kernel driver is more recent. Contact Karl.

This is a rare camera, as I understand. Nobody else has it.

Karl Gutwin. His email is at the URL that I gave above.

If there is that mysterious "someone", it is not anyone I know. As I said, virtually nobody has the device. I don't even know how the driver was developed in first place, using specs, reverse engineering or just black magic...
