Hi,
I have a problem with this camera.
http://www.theimagingsource.com/en_US/products/oem-cameras/usb-cmos-color/dfm21auc03ml/
It shows a picture but I cannot set the frame size and resolution of
the camera. The camera supports
60 frames per second and a resolution of 744x480 YUV2. However I
always get 372x480 and the colors are wrong.
This is what dmesg reports:
[179400.340015] usb 6-1: new high speed USB device using ehci_hcd and address 3

This is what I get with lucview:
luvcview 0.2.4
SDL information:
Video driver: x11
A window manager is available
Device information:
Device path: /dev/video0
Stream settings:
Frame format: UYVY
Frame size: 372x480 (requested size 744x480 is not supported by device)
Frame rate: 30/1 fps (requested frame rate 60 fps is not supported by device)
Thank you!
