[00000280] Obtain Thread error!
Trying now on my W500. I consistently get this error popup after about 3 seconds, using either uvcview or weblook. The camera light turns on but I get no picture (except the very first time I tried it, when I got a single frozen frame).
This webcam has a strange range of alternate interface settings. Most webcams start with the lowest bandwidth for the lowest setting and end with the highest bandwidth for the highest setting. It seems that this camera has one specific alternate interface setting for each of the reported video stream format frames.
With the 640x480 programs you could try e.g. "uvcview /i8" or "uvcview /i1 /u"
With the 320x240 programs you could try e.g. "uvcview /i9" or "uvcview /i2 /u"
Thanks.
I've just tried all four of the above. There is no change with any of them except for 'uvcview /i9' with the 320x240 program, which briefly produces a still image for a few seconds before producing the same error popup.
BTW, I previously also tried (not with these new parameters) an external USB webcam on this system. It produces the exact same error. I'm not sure how uvcview selects between the two webcams, but it does appear to use the external in this case, as the light on the external camera goes on for a few seconds (instead of the light on the built-in camera, as normal).
