From d134150be28e9016131b4c0b5c9273ff65cf2084 Mon Sep 17 00:00:00 2001 From: Joshua Colp Date: Sun, 11 May 2014 02:09:10 +0000 Subject: framehooks: Add callback for determining if a hook is consuming frames of a specific type. In the past framehooks have had no capability to determine what frame types a hook is actually interested in consuming. This has meant that code has had to assume they want all frames, thus preventing native bridging. This change adds a callback which allows a framehook to be queried for whether it is consuming a frame of a specific type. The native RTP bridging module has also been updated to take advantange of this, allowing native bridging to occur when previously it would not.
