Plugin Dispose & Finalize

HtGst

Hi

Just wondering if these methods need to implemented if I am using GstVideoEncoder base class?

Cheers,

Check the GObject documentation about what they mean, but basically you
will need them in this specific context if you allocate any resources
in the instance initialization or cache anything that needs to be
freed. However most things in GStreamer elements are to be freed during
state changes, symmetric to where they were allocated.

Hi

Well it’s more for  clarification purposes. I am looking at a piece of code that derives from GstVideoEncoder, which also implements _finalize callback. However, I don’t see it being called when pipeline goes to NULL or when pipeline is unreferenced.

Cheers,

This is the symptoms of a reference leak.

Hi

Could you kindly elaborate a bit, perhaps some debug suggestions.

Cheers,

Method will vary depending on GStreamer version. You could start with valgrind using GStreamer suppression file.
