Python Openvino MFX:不支持的扩展：rtsp://cris:pass@192.167.1.175:444/live/ch0，Ubuntu

您好，我正在Ubuntu 20.04.1 LTS上运行python Opencv运动检测脚本，运行良好，运行

source/opt/intel/openvino_2021/bin/setupvars.sh

后，如果使用openvino 2021.2.185运行它，则得到

openvino MFX:不支持的扩展：rtsp://cris:pass@192.167.1.175:444/live/ch0

如果我从IP摄像头更改它rtsp://cris:pass@192.167.1.175:444/live/ch0'至网络摄像头

src=0

然后一切正常

你能帮帮我吗

下面是错误
