cv2.VideoCapture('rtsp://192.168.60.70/channel1') gets MFX: Unsupported extension error

Hi,

I am running python yolo_v3 demo with OpenVINO 2020.3 LTS, I can run the demo successfully with the standard demo video "PedestrianTracker.mp4" and try to feed video from an IP cam. Slightly modified the demo code to capture video from IP cam:

#cap = cv2.VideoCapture(input_stream)
cap = cv2.VideoCapture('rtsp://192.168.60.70/channel1')

referred to OpenCV VideoCapture()  usage:

https://docs.opencv.org/master/d8/dfe/classcv_1_1VideoCapture.html#ac4107fb146a762454a8a87715d9b7c96

confirmed the rtsp stream works with VLC media player.

But it failed run python demo,

any specific configuration for IP cam? 

I got same failure even set to same FPS 25 and resolution 720p for IP cam and the  PedestrianTracker.mp4 file.

 

Thanks,

Chandler

This is a warning, not an error.

On Windows you need to download FFmpeg plugin for OpenCV to work with network streams. Run the ffmpeg-download.ps1 script located in the <openvino>/opencv directory.

Hi Chandler,

 

There should not be a particular issue when running on IP camera as some user managed to run using

"-i rtps://localhost:85444/live/stream" argument.

 

You could try running a standalone opencv code snippet to test the stream.

Hi Maksim,

Thanks for input.

after installing ffmpeg it works capturing video.........to some extend.

I can now see a picture and some inference results?

or I still need to tweak the IP cam streaming format to some specific format?
