This method is similar to runner_printf() but can be used
only once. The user needs to make sure all the pipeline
are in NULL state when this is called.
The method emits a "STOPPING" signal and at that point
overrides or monitors should do extra processing/checks if
needed.
+ Make use of it everywhere where it makes sense.
API:
gst_validate_runner_exit
GstValidateRunner::stopping signal
We do not want to know if the file is seekable etc, but in that case we
want to see that the results are stable throughout the various runs
Also make sure to report an understandable error if the media file info
could not be parsed
