gstreamer destroy threads

[wzho0776]

As from this page
https://gstreamer.freedesktop.org/documentation/application-development/advanced/threads.html?gi-language=c,
gstreamer automatically created new threads when necessary. Element can also
create their own thread.

Is there any way to manually destroy the thread that has been used by
gstreamer? Let's say after playing, i set pipeline to be NULL, i wanna clean
the threads and memory, then do some other tasks in the same process..

Is there any way to achieve this?

Generally, no.  All threads are managed internally by GStreamer itself
and should be destroyed when putting the pipeline into the NULL state.

Thanks Matthew!

As from the document, there exists a `GST_STREAM_STATUS_TYPE_DESTROY`
message. are we able to see this message when the pipeline set to NULL or
it's just not shown?

That depends.  Sometimes threads are created and destroyed without using
the stream status messages.  It's also possible that threads are created
using stream status messages but when the destroy messages are posted to
the pipeline's bus, the bus is flushing (to avoid reference cycles) so
the messages are simply dropped.  In all other cases, you should see the
appropriate destroy message.
