From 59db525cc08ef3472ff130d4a62ad7c97f98dddb Mon Sep 17 00:00:00 2001 From: Terry Wilson Date: Thu, 2 Dec 2010 18:00:27 +0000 Subject: [PATCH] Initialize offset for adaptive jitter buffer When the adaptive jitter buffer is enabled in sip.conf, the first frame placed in the jitter buffer fails with something like: jb_warning_output: Resyncing the jb. last_delay 0, this delay -215886466, threshold 1000, new offset 215886466 This happens because the offset is not initialized before calling jb_put(). This patch modifies jb_put_first_adaptive() to set the offset to the frame's timestamp.
