From c8ecc9954893a5e156c5972ee8e14c0a0c358b37 Mon Sep 17 00:00:00 2001 From: Mike Scheutzow Date: Sat, 7 May 2011 11:43:31 -0400 Subject: [PATCH] Improved detection of h264 bitstream with no B frames The sps.constraint_set0_flag indicates that the bitstream is baseline profile, which means the stream has no B-pictures.
