Thanks for your answer Sebastian. I agree with you but is there no risk to do
like it's done right now because if several threads tried to ref or unref
GST_CAPS_ANY that might lead to memory corruption. No?

Actually, the issue was coming from my own local code where GST_CAPS_ANY was
used without referencing it and later on unref...

By the way, I would expect from elements to always have a padtemplate on their
sink and src pads. In the description of input-selector there is a padtemplate
for each sink and src pads but when asking for its src pad template caps with
gst_pad_get_pad_template_caps () we can see there is no one and the function
returns a new reference of GST_CAPS_ANY. I didn't check the code of
input-selector but I'm wondering if it's normal.

So this bug is not from GStreamer if there is no risk of memory corruption as
discussed in the first part of this comment. I apologize for disturbing :)
