media information on decoder

[quang_openstack]

Hi everyone,
I am using gstreamer to decode video and audio from udpsrc like this

gst-launch-1.0 udpsrc port=5000 ! tsdemux name=demuxer demuxer. ! queue !
h265parse ! omxh265dec ! nvoverlaysink demuxer. ! queue ! faad !
audioconvert ! alsasink device=aux_plug

But how can I get media information like video resolution, framerate,
bitrate, ...
Any suggestion is appreciated.
Thank in advance

Yes it will, as GstElement inherits from GInitiallyUnowned.

If for one reason or another your call to gst_bin_add() fails unreffing the element remains your responsibility.

Well you can either use gst-discoverer with a udp:// uri, or see the caps exchanged between the elements by passing  -v to gst-launch I would say
