Hi, Ok so the camera isn't uvc compatible (it's using the sn9c102 driver), but all of the modes listed are supported by guvcview (BA81 and JPEG) although it seems the camera doesn't stream any data in BA81 mode, so you could try and change the output to jpeg mode, just use the GUI or from the command line: guvcview --format=jpeg
for BA81 use: guvcview --format=bggr Best regards Paulo 2009/8/21 Dotan Cohen <[email protected]>: > 2009/8/21 Paulo Assis <[email protected]>: >> Hi, >> Could you please try with guvcview: >> >> guvcview --verbose >> >> This should list all frame formats available on your camera. >> >> luvcview only supports yuyv and mjpeg, so other formats are not available. >> >> This particular model seems to support RGB24, just made available in >> guvcview 1.1.3 and completely untested :-), so this is a very good >> opportunity to contribute in the development of a GPL application, >> please just report your findings, I'm obviously very interested in the >> results. >> >> >> Anyway the camera doesn't seem to be recognized has a uvc device >> (there are no uvc messages in dmesg), you can confirm this with lsusb. >> >> > > Thanks, Paulo.
