我用的是2.6.30.4内核,摄像头是中芯微的,插入USB摄像头后,显示的内容是:
[root@EmbedSky /]# usb 1-1: new full speed USB device using s3c2410-ohci and add
ress 4
usb 1-1: New USB device found, idVendor=0ac8, idProduct=3330
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1: Product: Sirius USB2.0 Camera
usb 1-1: Manufacturer: Vimicro Corp.
usb 1-1: configuration #1 chosen from 1 choice
uvcvideo: Found UVC 1.00 device Sirius USB2.0 Camera (0ac8:3330)
input: Sirius USB2.0 Camera as /devices/platform/s3c2410-ohci/usb1/1-1/1-1:1.0/i
nput/input3
接着,我输入WebCam_USB进行测试时,如果出现如下问题:
[root@EmbedSky /]# WebCam_USB
MJPG-streamer [547]: starting application

MJPG-streamer [547]: MJPG Streamer Version.: 2.0

MJPG-streamer [547]: Format............: MJPEG
Unable to set format: Invalid argument
Init v4L2 failed !! exit fatal
i: init_VideoIn failed
MJPG-streamer [547]: init_VideoIn failed
请问这是什么原因,如何解决? |
