我正在尝试让 uv4l 与罗技相机 310 一起工作。我转到地址 XXX:8090/stream,它工作了几秒钟然后停止。为了取回它,我需要重新启动 pi。此外,它有时会输出这些:

我遵循了本指南http://www.linux-projects.org/uv4l/installation/。我看过无数关于人们做同样事情的视频,但这对我不起作用。让我知道是否需要其他任何东西来帮助解决这个问题。

你得到一个内核哎呀。这意味着内核内部发生了一些不好的事情。最有可能的是,存在与用户空间 USB I/O 相关的内核错误,因为这就是 uv4l 的 UVC 驱动程序正在使用的。尝试升级 Raspberry Pi 上的内核并检查问题是否仍然存在。

该错误可能是由相机的正常I/O触发的,但也可能是存在异常导致相机的意外数据,然后被内核处理不当。造成这种情况的可能原因可能是 USB 电缆或连接器损坏,或者 Pi 并非完全不可能,电源不足,无法保持足够高的电压以使硬件可靠运行。
