If you use gst-launch-1.0, use the -e switch on it. Otherwise the muxer
has no chance to finalize the file when you shut down the application.
In the case of MP4 you will get a broken file, in the case of Matroska
it is only missing some metadata like the duration.
In your own application you would need to ensure to send an EOS event
to the pipeline and only shut it down once you get an EOS message back
