From bf65acf11fd107376e5591e24f0d93de05057fab Mon Sep 17 00:00:00 2001 From: Sjoerd Simons Date: Mon, 10 Oct 2011 19:01:23 +0100 Subject: [PATCH] gstrtpg722pay: Compensate for clockrate vs. samplerate difference The RTP clock-rate used for G722 is 8000, even though the samplerate is 16000. Compensate for this by pretending G722 has 8 bits per sample instead of the 4 bits as if it were a codec that ran at half the speed, but with twice the number of bits.
