Yeah , I thought something was wrong when the window didnt resize for the larger sizes! the windows partition was re-installed. Maybe the wrong drivers were installed. I'll try to find the right drivers and see if i can get new traces. But the 1280x1024 didnt work either , it causes a horizontally cut image which stutters and has a dark green tint on the lower half. With these errors at times: Jun 26 15:37:49 vish-laptop kernel: [ 391.855609] gspca-2.9.45: ISOC data error: [12] len=1024, status=-71 Jun 26 15:38:05 vish-laptop kernel: [ 407.987624] gspca-2.9.45: ISOC data error: [57] len=1024, status=-71 Jun 26 15:44:50 vish-laptop kernel: [ 812.635584] gspca-2.9.45: ISOC data error: [9] len=1024, status=-71 Jun 26 15:45:13 vish-laptop kernel: [ 835.899634] gspca-2.9.45: ISOC data error: [91] len=1024, status=-71 (In reply to comment #3) > But the 1280x1024 didnt work either , it causes a horizontally cut image > which > stutters and has a dark green tint on the lower half. This may mean that the bridge vc0321 cannot handle images bigger than 640x480...

I get these stutters , cut line during 640x480 mode too , but it is rare.[dont get the green tint on half picture though] . With the 1280x1024 , this happens almost all the time. I added back the 1280x1024 resolution in gspca-2.10.9 for your webcam with the po3130nc sensor. Have you the same result?

Its the same stuttering as observed earlier. Also, seeing that since we are now using the driver from .33 kernel , the 640x480 is also stuttering as i had mentioned earlier on the other bug. [which was expected.] But the two stuttering differ. 640x480 had various cut lines and keeps repeating , but in the 1280x1024 , the image is cut in half and stutters the same more of two static frames. And the frames change only at very long intervals |
