From 5473387b9382a35967d1fcd550482efa3a31d44f Mon Sep 17 00:00:00 2001 From: Zahari Doychev Date: Mon, 3 Aug 2015 08:57:19 -0300 Subject: [PATCH] [media] coda: drop zero payload bitstream buffers The buffers with zero payload are now dumped in coda_fill_bitstream and not passed to coda_bitstream_queue. This avoids unnecessary fifo addition and buffer sequence counter increment.
