USB Cam ImagingSource Problem

edit

Hello, I am currently trying to get the DMK 42BUC03 link_to_camera from ImagingSource to work with an ROS package.

I tried usb_cam:

[ERROR] [1443095249.460258490]: Webcam: expected picture but didn't get it...

I tried uvc_cam:

opening /dev/video0
pixfmt 0 = 'GREY' desc = 'Greyscale 8-bit (Y800)'
  discrete: 1280x960:   1/30 1/25 1/15 1/10 
  discrete: 720x480:   1/60 1/30 1/25 1/15 
  discrete: 640x480:   1/60 1/30 1/25 1/15 
  int (Gain, 0, id = 980913): 34 to 255 (1)
  int (Exposure (Absolute), 0, id = 9a0902): 1 to 300000 (1)
Segmentation fault (core dumped)

i tried the normal vlc player for ubuntu:

I get an image but it says:

[0x7fcd5401b198] main blend error: blending RGBA to GREY failed
[0x7fcd5401b198] blend blend error: no matching alpha blending routine (chroma: RGBA -> GREY)

The camera is set to uvc mode and it is an USB2.0 camera. It is detected correctly from my linux system. Thx for your help.
