Hello, I am using OpenCV (2.4.11) on Windows (Cygwin). I want to open a video file but I get this error message:

GLib-GObject-CRITICAL **: g_object_set: assertion 'G_IS_OBJECT (object)' failed

Editing images works great, so my installation in general should be fine. Maybe I am missing a Codec? My code looks like this:

VideoCapture cap(argv[1]);
if(cap.grab()){
    cout<<"success"<<endl;
}


./test.exe video.avi

I already searched for a solution, but I didn't found any useful ideas... Thank you for your help!

did you somehow build with gstreamer ?

(where else should such an error come from ?)

You are right, I am using gstreamer. I installed some additional plugins and now I get an other error:

GStreamer Plugin: Embedded video playback halted; module avidemux0 reported: Could not demultiplex stream.
OpenCV Error: Unspecified error (GStreamer: unable to start pipeline
) in cvCaptureFromCAM_GStreamer, file /usr/src/ports/opencv/opencv-2.4.11-1.x86_64/src/opencv-2.4.11/modules/highgui/src/cap_gstreamer.cpp, line 773

Webm Format is working fine...The error message is still cryptic to me :/

maybe you can try this overload , and see, if ffmpeg or dshow canhandle your video
