Hello,

I somehow can't get the USB Video Genie to work with VLC or xawtv, so I suppose the problem starts in v4l. The device is a small USB box with a grey button and a S-Video and a Composite input jack. Plugging the USB box in, I get

kernel: usb 6-2: new full speed USB device using uhci_hcd and address 2
kernel: usb 6-2: new device found, idVendor=0573, idProduct=0003
kernel: usb 6-2: new device strings: Mfr=0, Product=0, SerialNumber=0
kernel: usb 6-2: configuration #1 chosen from 1 choice
kernel: Linux video capture interface: v2.00
kernel: usbvision_probe: USBGear USBG-V1 resp. HAMA USB found
kernel: USBVision[0]: registered USBVision Video device /dev/video0 [v4l2]
kernel: USBVision[0]: registered USBVision VBI device /dev/vbi0 [v4l2] (Not Working Yet!)
kernel: usbcore: registered new interface driver usbvision
kernel: USBVision USB Video Device Driver for Linux : 0.9.9
kernel: saa7115 1-0024: saa7111 found (1f7111d1e200000) @ 0x48 (usbvision #0)

That's all I find in the log. From v4l-info I get

### v4l2 device info [/dev/video0] ###
general info
VIDIOC_QUERYCAP
driver : "USBVision"
card : "USBGear USBG-V1 resp. HAMA USB"
bus_info : "6-2"
version : 0.9.9
capabilities : 0x5020001
[VIDEO_CAPTURE,AUDIO,READWRITE,STREAMING]

...

VLC does not open a window when I select the device for play; doing a plain "cat /dev/video0" does not produce anything. Tried the different inputs, no result. Am I missing something here? Do I require a special firmware for this device?

Thanks for any help,

Michael

Please try with mplayer for example:
mplayer -tv driver=v4l2:width=320:height=240:norm=SECAM:outfmt=yuy2:channels=21-F2 tv:// Customize the norm, and channel to your needs.
vlc should work with a line like this:
vlc v4l2:///dev/video0:width=320:height=240:standard=PAL:input=2
this for looking at the S-video input.
