I don't exactly know how your encoder is working, but this may mean
you're re-sending a key frame each time.

I know you already made this check previously, but was the received

looks like this is replying to my former question, but maybe you can

I suggest you to try and terminate it nicely from an application as
To build a gst-launch style pipeline in your C application, use the following:
Indeed you won't get an EOS here, but maybe you can simply terminate
the g_main_loop after a stdin event (e.g. pressing "ENTER"). More
evolved methods based on probes and I/O stats are still possible but
imho useless so far.
