Understanding Locks and Threading in Gstreamer?

Hi All,

I'd like to understand more about the locks and threads in GStreamer.

Can anyone point me to some docs or code to read to help get a grip on 
it all?


I've read this 
<https://gstreamer.freedesktop.org/documentation/additional/design/dynamic.html?gi-language=python> 
that mentions it's important to understand about the application and 
streaming threads, and this 
<https://gstreamer.freedesktop.org/documentation/additional/design/events.html?gi-language=python> 
that mentions 'the STREAM_LOCK' in various places. I think I've read a 
few other pages that reference these topics too, but haven't found 
anything that gives a good grounding about what's behind the design.

I've definitely fallen foul of issues from not understanding enough of 
these low-level details while trying to move up the learning curve and 
use signals to trigger actions. Sometimes I've had lock-ups immediately 
every time and sometimes it has taken a few thousand runs to spot the 
impact of a race condition, so I'd love to get clarity!


Thanks for reading and all the help so far!

Will.
