Description Judy Liqiong Hao 2011-12-09 15:49:21 PST
There is a memory leak in function "webkit_web_src_init" of "WebKitWebSourceGStreamer.cpp" 
with setting pad-templates for ghostpads.

gst_static_pad_template_get() is used to get a GstPadTemplate out of static pad
template. This is then passed as a parameter to gst_ghost_pad_new_from_template, 
which does a ref, but does not take ownership. 

Attached is a patch that unrefs the pad template after it's used.

Thanks for spotting this!
The pad template is still leaked in the case where appsrc is not created though?

Can you use GRefPtr for this GstPadTemplate pointer? You'd need to add support for it in GRefPtrGStreamer.
