Interesting - the version in OE-core is 84 revisions behind the master/HEAD.
Should I bother debugging what's in OE-core or see what's up with the latest
code?
If you want to know what elements get dynamically created then I believe turning on debug (see the packageconfig) will let you write out dot files for each stage of the pipeline.
I don't see any 'debug' PACKAGECONFIG settings, only GSTREAMER_1_DEBUG
variable and that seems to only affect the core.
