升级到 20.04LTS 服务器后,我的 Kodicom 4400R 相机卡无法工作

升级到 20.04LTS 服务器后,我的 Kodicom 4400R 相机卡无法工作

这些卡在 16.04 服务器下工作,但是该服务器死机了,因此我建立了一个运行 20.04 的新机器,当我安装这些卡时,它们不工作了。

我尝试使用 zoneminder 查看摄像头,但没有成功。为了解决问题,我删除了 zoneminder 中的监视器(以确保设备未被使用),下载了 v4l-utils*,构建了 v4l2grab,当我运行它时,保存的文件不包含任何图像。

*我克隆了 v4l-utils repo,cd 到 v4l-utils,检出 v4l-utils-1.18.0(20.04LTS 使用的版本),运行 make(无错误),cd 到 contrib/test 并运行 ./v4l2grab(无参数)。

这是自系统启动以来我第一次尝试运行 v4l2grab 时的 dmesg 输出(启动时和此处之间的 dmesg 中还有更多内容,但我现在无法发布。

看起来 v4l 驱动程序中的某些东西正在崩溃,但我没有足够的知识来自己解决这个问题。

如果我应该发布更多信息,请告诉我,例如

  • 来自 dmesg 的更多内容
  • 修改信息 bttv
  • systool-vm bttv
  • v4l-信息 lspci
  • 扫描

或者其他的。我会密切关注这个问题。

答案1

我在新盒子上重新安装了所有东西,现在卡可以正常工作了。想想吧。
