如何在VLC中捕获视频流？

Question

我想从网络摄像机捕获视频流。 我正在通过控制台使用vlc。

我使用以下命令：

cvlc /dev/video0

我有以下例外情况...

VLC media player 2.0.5 Twoflower (revision 2.0.5-0-g1661b7d)
[0x8731db8] dummy interface: using the dummy interface module...
[0xb5000af0] filesystem access error: cannot open file /dev/video0 (Invalid argument)
[0xb5000af0] main access error: Reading from a file failed
[0xb5000af0] main access error: VLC cannot open file "/dev/video0". (Invalid argument)
[0xb4f005f0] main input error: open of `file:///dev/video0' failed
[0xb4f005f0] main input error: This source is not open
[0xb4f005f0] main input error: VLC could not open the MRL 'file:///dev/video0'. Look for more details in the log file.

有人知道如何解决吗？
