[Linphone-users] webcam not working with linphone (but with other apps)

[Florian Hollerweger]

Hi all,

The webcam on my Samsung Q45 laptop running Debian works under luvcview,
Skype, and other applications, but under linphone (version 3.3.2 from
the Debian repositories), I just get a black screen.

I presume that this is related to the following debug printout:

message: v4l_start: open, fd=13
message: Found Vega USB 2.0 Camera. device. (maxsize=1280x1024,
minsize=48x32)
message: Default picture properties:
brightness=32768,hue=32768,colour=13797,contrast=31710,depth=16, palette=8.
warning: Could not set picture properties: Invalid argument
warning: Could not set picture properties: Invalid argument
message: Driver supports YUV422, using that format.
message: Trying to set capture size to 352x288

message: v4l_configure: cannot set HW frame rate control
message: MSV4l: Webcam is Vega USB 2.0 Camera..
message: v4l_thread starting
error: Could not get mmap properties: Invalid argument


Here are some hardware details:

Manufacturer:   Vimicro
Model:          Vega USB 2.0 Camera
VID:            0AC8
PID:            C302
driver:         uvcvideo


I would appreciate any help on this one. Thanks for this amazing piece
of software!

best,
