网络摄像头仅适用于 luvcview

网络摄像头仅适用于 luvcview

有人知道为什么我的网络摄像头可以在 luvcview 中工作,但在 cheese、vlc、firefox 等中却不能工作吗?

VLC 似乎根本无法从相机捕获任何东西。cheesy 可以工作大约 2 秒钟,但视频是半黑的,并且有水平线穿过。Firefox getUserMedia 示例从不调用 loadeddata 回调。

luvcview 可以正确显示网络摄像头视频,并能够将其捕获到 avi 文件中。有什么线索告诉我应该从哪里开始查找吗?以下是网络摄像头的 lsusb 转储和 luvcview 支持的格式列表:

答案1

我的 Razer Blade 2015 中有一个类似的 Realtek 设备,只要将其设置为 720p,它就可以与所有设备配合使用。它可能可以在较低的分辨率下工作,但这就是我测试的全部内容。

我有一个 1080p USB 摄像头,有时会用到,但这个摄像头的分辨率设置太高了。我将其切换到 720p,然后重启 cheese,它就可以正常工作了。
