Hello!

I am trying to capture an sdp file with vc2.VideoCapture using Python 2.7.13 and opencv 3.2.0 in win10 using:

cap = cv2.VideoCapture(“my_file.sdp”)

but cap.isOpened() never becomes true.

The program exits with code 0 and a message:

[rtp @ 07902760] Protocol not on whitelist 'file,crypto'! 
warning: Error opening file (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:779) 
warning: my_file.sdp (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:780)

The sdp file plays ok from command line with ffplay –protocol_whitelist file,udp,rtp my_file.sdp

(For some unknown reason vlc shows only one frame…)

Any clues on how to proceed?

Thanks in advance, Vagelis
