Thanks to Dimitri, and Chris the raw image format was deciphered for the test images, b&w and color. The color still has a rolling effect in one direction, but its certainly recognizable. Chris thinks he can figure it out completely real soon. The data, at least in snapshots does not appear to be compressed at all. I read an old press release about VLCE - the proprietary lossless compression technology, but it occurs to me that QuickCam's didn't use their VIDEC color compression except when transferring streaming video, not with simple snapshots... so this makes sense. We aren't proposing to decipher that codec it may not be necessary for the ultimate goals, rather a series of well timed snapshots at the descretion of the Linux driver or application would be better. Maybe: #cat /dev/usb/3cam > /home/mypics/frame.raw We are going to capture more data at various resolutions and color depths and work out a general procedure for converting them to frames tonight. If that works, I guess the next step would be to start trying to send commands to the USB device within Linux and simply capturing the frame dumps to a file. After that, bolt on a V4L interface, and we'll call it quits. Thats the plan sort of, if anyone would like to make suggestions regarding communicating with USB devices under Linux in a testing mode.. it would be appreciated. Since I'm a very new person to USB, something in the way of "the simplist" C/C++ program ever written to communicate with a USB device would be very welcome. I have to say the authors of USB Snoopy really made this progress possible, Dimitri has been on target with every suggestion, and Chris has been relentless at finding the "correct" headers to bolt onto the raw.bin files to turn them into viewable images. We'll post more results as they become available. =================================================== John Willis Microcomputer support Internet Publishing Technologies Group TXU Communications icq : 47700679 web : www.txucom.com, www.johntwillis.com email: [EMAIL PROTECTED] Phone: 409.788.7523 FAX : 409.788.7566 this is my digital finger print: C219 3E66 C570 9CFF B0C4 A947 01C5 A0B3 6173 34B9 =================================================== --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
