我有一个 USB 网络摄像头（未知品牌，没有标记），在我的 Raspberry Pi 上检测到很好。

这是 lsusb 的输出

Bus 001 Device 005: ID 1267:0103 Logic3 / SpectraVideo plc G-720 Keyboard

但是，当我运行运动时，使用带有唯一默认配置的 /dev/video0 更改了分辨率并将网络摄像头主机设置为关闭，以便我可以在网络上流式传输它。这是我跑步时的日志

相机上的灯在开始时亮起然后又熄灭，有人知道我遇到的任何错误吗？

谢谢！

您的问题在日志中：

config image height (120) is not modulo 16

所以你需要不同的图像分辨率。

查看您的设备支持什么

$ uvcdynctrl -f

选择一个 y 分辨率为 16 倍数的分辨率。例如，如果为您的相机列出了 640x480。

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。在我设置高度 640 宽度 480 之前，我的没有工作。流很棒！只需要弄清楚webstream身份验证的补丁。目前我有这个需要登录的网络服务器的流式传输，但是如果有人输入我的 IP 加上我正在流式传输的端口，这可以绕过。

即使在conf文件中配置不同，motion 也会使用它在运行时检测到的可能分辨率（至少根据我的经验）。

此外，似乎在conf文件中设置了一个不受支持的调色板，并且动作选择了它检测为受支持的两个调色板之一。您是否尝试在conf文件中将调色板设置更改为“0”（S910） ？

最后，Pi 的 USB 支持存在一些关于大数据块的已知问题和目前尚未解决的问题。降低帧速率在其他情况下也可能有所帮助（在这种情况下，我认为我无济于事，因为该过程已经因第一张图像而失败）。

尝试v2l4-ctl --list-format-ext查看您的相机支持哪些像素格式和图像大小的组合。这S910是一款便宜的旧相机，您可能需要升级。

我建议您尝试 guvcview 而不是运动。它运行得更快，并且在我的 Pi 上提供了更好的图像。它在 X 下运行。

guvcview 的两个注释 - 将 POWER LINE FREQUENCY 设置为您当地的电源频率。- 将分辨率设置为 640 x 480。

guvcview 需要大约 50% 的处理器功率。是的，也可以使用 USB 集线器！

嗯。
