    Here you can see, VLC is always waiting on buffering, while other players can get buffers from my RTSP server, also I can see RTP packets on wireshark that server is continuously sending data to VLC.

    Can someone help me on this issue ?

    Very much thanks in advance.

  • VideoWriter OpenCV - cannot put pipeline to play in function CvVideoWriter_GStreamer::open

    24 octobre 2019, par 021

    Almost exactly the same question : OpenCV error - cannot put pipeline to play in function CvVideoWriter_GStreamer::open

    Context : I’m trying to create a video and save it in a .avi file with OpenCV 3.3.0 and Python 2.7.

    Problem : This code :

    fourcc = cv2.VideoWriter_fourcc(*'XVID')
    
out = cv2.VideoWriter('data/out/output.avi', fourcc, 30, (800, 600))

    Raises :

    (python2.7:12345): GStreamer-CRITICAL **: gst_element_make_from_uri: assertion 'gst_uri_is_valid (uri)' failed
    

    
** (python2.7:12345): CRITICAL **: gst_ffmpeg_cfg_set_property: assertion 'qdata->size == sizeof (gint64)' failed 
    
OpenCV Error: Unspecified error (GStreamer: cannot put pipeline to play ) in CvVideoWriter_GStreamer::open, file /soft/OpenCV3.3/opencv-3.3.0/modules/videoio/src/cap_gstreamer.cpp, line 1690
    
VIDEOIO(cvCreateVideoWriter_GStreamer (filename, fourcc, fps, frameSize, is_color)): raised OpenCV exception:
    

    
cap_gstreamer.cpp:1690: error: (-2) GStreamer: cannot put pipeline to play
    
 in function CvVideoWriter_GStreamer::open

    Question : How do I solve this problem so I can write video files with OpenCV ?
