答案1
如果幸运的话，您的捕获设备会在您插入后立即被识别并准备使用。如果是这样，ls /dev/video*您应该会看到该设备。假设它是唯一插入的设备，它将是 /dev/video 或 /dev/video0。
如果您没有看到该设备，您可能需要寻找合适的驱动程序。这个帖子表明它实际上是一个已重新命名的 Geniaech EZ Grabber，并且它使用 uvcvideo 驱动程序。
要测试该设备，您可以使用 mplayer：mplayer /dev/video应该可以。
我喜欢甚高频液晶它可以用于大多数事情，并且可以从捕获设备进行视频流传输。您可以从 Synaptic 安装 VLC。VLC 的使用非常简单，但是此条目来自 VLC 文档 Wiki应该可以帮助你开始。
