最近，我在 Ubuntu 22.04.3 LTS（64 位）上的相机开始出现问题。相机会重复拍摄帧，最终不会显示任何比开头的片段更新的帧。
我用来捕获图像的程序是 Cheese，在命令行中运行时它会输出消息
(cheese:4398): cheese-WARNING **: 13:53:33.993: 许多缓冲区被丢弃。: ../libs/gst/base/gstbasesink.c(3143): gst_base_sink_is_too_late (): /GstCameraBin:camerabin/GstViewfinderBin:vf-bin/ClutterGstVideoSink:cluttergstvideosink0:
可能存在时间戳问题，或者这台计算机太慢。
但是，如果我改用 sudo 运行 Cheese，这种行为就会改变，它会输出以下内容：

奇怪的是，使用 sudo 运行它允许相机再次开始工作。
有人知道如何修复它，以便我不需要使用 sudo 来使用我的相机吗？
