Hi:

I am still playing with pjsip 2.0 with the video. I am triying to setup de
camera under linux, but I have a problem. When I run ./vstreamutil.c I get
the next output.


 16:43:50.888     v4l2_dev.c  Found capture device UVC Camera (046d:0990)
 16:43:50.889     v4l2_dev.c    Enumerating formats:
 16:43:52.211     v4l2_dev.c     Unsupported: MJPEG
 16:43:52.211     v4l2_dev.c     Supported: YUV 4:2:2 (YUYV)
 16:43:52.211     v4l2_dev.c     Unsupported: RGB3
 16:43:52.211     v4l2_dev.c     Supported: BGR3
 16:43:52.211     v4l2_dev.c     Unsupported: YU12
 16:43:52.211     v4l2_dev.c     Unsupported: YV12
 16:43:52.211     v4l2_dev.c  Video4Linux2 initialized with 1 devices
 16:43:52.211 colorbar_dev.c  Colorbar video src initialized with 1 devices:
 16:43:52.211      sdl_dev.c  SDL initialized

and as ffmpeg only suppor I420 and YV12 (if I am not wrong) I get the
problem that the pixel format from the camera and the codec doesn' t match
so it launchs an error.

>From my point of view I think that mz v4l2 is doing something wrong because
when I look the dev I see some references to YV12 but it sais that is
unsupported.

Could you help me?

Regards

Jorge
