Proper way to clean up a GstPipeline

[Alexander Sack]

Hello all:

Really simple, dumb question:

For all of my pipelines, I shutdown/clean like so:

pipeline.state = Gst.NULL
pipeline = None

But I just read here:

https://gstreamer.freedesktop.org/documentation/gstreamer/gstpipeline.html?gi-language=python

I should also include a pipeline.unref()? But that yields things like:

(foobar:20365): GStreamer-CRITICAL **: 15:56:51.646: gst_object_unref:
assertion '((GObject *) object)->ref_count > 0' failed

What is the official/correct way to completely clean-up a pipeline from
within a Python application? The pipeline is created using parse() (and the
pipeline has been validated witih gst-launcher-1.0).

Also, if I don't care about EOS can't I just clean up the pipeline without
handling any bus messages (think a viewer where capturing any flushed out
frames is immaterial and I just want to close immediately and free all
resources).

Thanks!
