Hello, I have using opencv 2.4.13 and 3.1. I have tried to open video file, but got some errors as below: (app:7400): GLib-GObject-CRITICAL **: g_object_set: assertion 'G_IS_OBJECT (object)' failed

Regards, Kishan Patel.

that's from gstreamer, and it means, some nessecary plugin is not installed.

Okay, so how can we identify that which plugin is require to install?

Hello berak, i have installed some libraries(gstreamer0.10-plugins-base, gstreamer0.10-plugins-good) and could not install(gstreamer0.10-plugins-bad-multiverse, gstreamer0.10-plugins-ugly-multiverse). Then i got error as below:

Actually, i have used gstreamer and convert sample video-file into BGR format using VPE and VIDEOCONVERT. This converted video-file can open by "VOOYA" software but it did not open by OpenCV application.
