Description Sebastian Rasmussen 2014-08-09 11:35:03 UTC
This is another instance of gst_pad_get_pad_template_caps() returning a reference but the code does not release the reference. The attached patch aims to fix this.

This is not correct. The code goes on to modify the returned caps in some cases, so they need to be writable.

Made caps writable as per review comment. make -C tests/check elements/opus.check still succeeds.
