From 5fa6d211f35c296c2e543f263d38708daf207d5c Mon Sep 17 00:00:00 2001 From: Sean Bright Date: Tue, 27 Dec 2011 17:17:13 +0000 Subject: [PATCH] Once an audiohook is attached to a channel, we continue to transcode all of the frames, even after all of the hooks are detached. This patch short-cicuits us out before we transcode unnecessarily. ........
