请问我每次运行的时候都出这个提示
MJPG Streamer Version.: 2.0
i: Using V4L2 device.: /dev/video0
i: Desired Resolution: 640 x 480
i: Frames Per Second.: 5
i: Format............: YUV
i: JPEG Quality......: 80
ERROR opening V4L interface: No such file or directory
Init v4L2 failed !! exit fatal
i: init_VideoIn failed
是因为我的摄像头不支持吗?
