Openvino MFX: Unsupported extension: rtsp://cris:pass@192.167.1.175:444/live/ch0 , Ubuntu

[Calincan]

HI I'm running python Opencv motion detection script on Ubuntu 20.04.1 LTS  which is working fine ,

after running source /opt/intel/openvino_2021/bin/setupvars.sh and 

 if I run it with OpenVINO 2021.2.185 then I got Openvino MFX: Unsupported extension: rtsp://cris:pass@192.167.1.175:444/live/ch0  and If I change it from IP camera src='rtsp://cris:pass@192.167.1.175:444/live/ch0'  to  webcam  src=0  then everithing works fine .

Can you please help me please ??

Below is the error

Try to install FFmpeg package, it should be able to grab frames from network source:

sudo apt install ffmpeg

[Calincan]

Many thanks ! what I see is that ffmpeg is already the newest version (7:4.2.4-1ubuntu0.1).

[Maksim_S_Intel]

Try to play the stream using ffmpeg directly, e.g.:

ffplay <uri>

 You can capture more logs from OpenCV and FFmpeg by setting environment variables:

OPENCV_VIDEOIO_DEBUG=1
OPENCV_LOG_LEVEL=debug
OPENCV_FFMPEG_DEBUG=1

Special environment variable can be used to pass extra options to underlying FFmpeg backend: OPENCV_FFMPEG_CAPTURE_OPTIONS. See this thread for some examples: https://answers.opencv.org/question/186903/opencv-streaming-h264-over-rtsp-using-ffmpeg-in-version-34/

Many thanks for the answer , the solving solution was described by the link shared specificaly by : uninstalling the curent version :l_openvino_toolkit_p_2021.2.185 and installing older version: l_openvino_toolkit_p_2020.3.341
