If you have your own application, you can easily use a pipeline ending with
fakesink and do something in the have-buffer callback of the fakesink. You
can even play around with QoS by setting qos=true and sync=true on the
fakesink. Attached is some code for the have-buffer callback.
If you're calling gst-launch on the command line and can't be bothered with
creating an application, and accuracy is not essential, then you can do
something like this:
gst-launch uridecodebin uri=... ! fakesink num-buffers=$BUFFERS > $LOGFILE
TIME=$(sed -n 's/Execution ended after \([0-9]*\)[0-9][0-9][0-9] ns./\1/p' \
echo FPS: $(( $BUFFERS * 1000000 / $TIME ))
