使用议案上的树莓派摄像头流媒体问题
我有一个USB摄像头（未知的，无标记），在我的Raspberry Pi上被发现很好。
这是lsusb的输出
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001 Device 004: ID 0c45:608f Microdia PC Camera (SN9C103 + OV7630)
Bus 001 Device 005: ID 1267:0103 Logic3 / SpectraVideo plc G-720 Keyboard
但是，当我运行议案，使用/ dev / video0与唯一的默认配置改变了分辨率，并设置网络摄像头主机，以便我可以在网络上流。 这是我运行动作时的日志

照相机上的灯在开始时亮起，然后再次熄灭，有人识别出我收到的任何错误吗？
谢谢！
我认为您需要将conf文件中图像的高度和宽度设置为您的相机规格。 我没有工作，直到我把高度640宽度480.流很好！ 只需要弄清楚webstream认证的补丁。 目前我有这个流媒体到我的网络服务器，需要登录，但如果有人输入我的IP加端口即时通讯，这可以被绕过。
即使配置文件的配置不同，运动也会使用它在运行时检测到的可能分辨率（至少在我的经验中）。
此外，似乎在conf文件中设置了不受支持的调色板，并且动作会选中它检测为支持的两个调色板之一。 您是否尝试将配置文件中的调色板设置更改为“0”（S910）？
最后，Pi的USB支持有一些已知的问题，并且至今尚未解决有关大块数据的问题。 降低帧速率也可能有助于其他情况（在这种情况下，我认为，我不会帮助，因为该过程已经失败并显示第一个图像）。
尝试v2l4-ctl --list-format-ext查看相机支持像素格式和图像大小的组合。 S910是一款便宜的旧相机，您可能需要升级。
