树莓派下使用openCv启动摄像头, 读取实时视频流, 报错

树莓派下使用openCv启动摄像头, 读取实时视频流, 报错, 信息如下 :

[ WARN:0] global /home/pi/opencv/modules/videoio/src/cap_gstreamer.cpp (935) open OpenCV | GStreamer warning: Cannot query video position: status=0, value=-1, duration=-1

百度查说是修改分辨率和帧率 , 改了改还是不行 ,一直提示这个错误 . openCv版本是4.4.0

报错内容发过来

GStreamer警告：嵌入式视频播放暂停；模块v4l2src0报告：内部数据流错误。

报这个错

你好，请问你解决了吗，我被这个问题困扰好久了
