Logitech B990 (UVC) slow initialization, WebRTC problems

Hi,

I have a Logitech B990 webcam, it is a UVC webcam:

ID 046d:0828 Logitech, Inc. HD Webcam B990


When I start guvcview, the webcam's blue lights flash for 5 - 7 seconds
and then a greenish picture appears.

If I go to the video tab in guvcview and change it from MJPG to YUYV or
H264 then the picture looks normal.

My WebRTC browser often tries to initialize the webcam but gives a
JavaScript error before it becomes ready.  It doesn't appear to work
with cheese either.

I've attached the following details:


lsusb.log  (from lsusb -v -d 046d:0828)

dmesg.out  (uvcvideo traces)

guvcview.out  (stdout/stderr from guvcview)


Is this a defect with the webcam or is it simply not supported?  I
notice it is not in the list[1].  This was originally discussed on the
Jitsi Users list[2]

Regards,

Daniel
