使用最新版ffmpeg-0.11 libx264-125,使用默认编码时,用Eyecard发现profile-idc一直是PROFILE_H264_HIGH (profile-idc=100),但是项目要求是baseline,设置了AVCodecContext的->profile=FF_PROFILE_H264_BASELINE也没用,经过多方查找,需要如下解决方法:
SDP中的H.264的SPS和PPS串,包含了初始化H.264解码器所需要的信息参数,包括编码所用的profile,level,图像的宽和高,deblock滤波器等。 由于SDP中的SPS和PPS都是BASE64编码形式的,不容易理解,附件有一个工具软件可以对SDP中的SPS和PPS进行解析。 用法是在命令行中输入: spsparsersps.txtpps.txtoutput.txt 例如sps...

1、BaselineProfile:基本画质。支持I/P 帧,只支持无交错(Progressive)和CAVLC; 2、Extendedprofile:进阶画质。支持I/P/B/SP/SI 帧,只支持无交错(Progressive)和CAVLC;(用的少) 3、Main profile:主流画质。提供I/P/B帧,支持无交错(Progressive)和交错(Interlaced),也支持CAVLC 和CABAC 的支持; ...
