Subject: Initialize offset for adaptive jitter buffer
X-Git-Tag: 1.4.39-rc1~3^2~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=59db525cc08ef3472ff130d4a62ad7c97f98dddb;p=thirdparty%2Fasterisk.git

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.
