网络摄像头罗技和Linux

我有罗技C310相机，声称特性为720p 30fps .

如果您将相机连接到窗口，录制完全符合规定的720p 30fps - 图像清晰 .

挑战是将相同的相机连接到OrangePI（服务器Armbian）并在其上保存视频文件 .

相机显示为/ dev / video0 .

sudo ffmpeg -f v4l2 -s 1280x720 -i /dev/video0 output.wmv

结果，我得到一张频率为5 fps的易碎图片 .

也许我正在使用ffmpeg错误？请帮助我在Linux上有网络摄像头经验的人...提前谢谢 .

USB摄像头配置：

v4l2-ctl --all --device=/dev/video0
