1 I帧,P帧,B帧,IDR帧,NAL单元 I frame:帧内编码帧,又称intra picture,I 帧通常是每个 GOP(MPEG 所使用的一种视频压缩技术)的第一个帧,经过适度地压缩,做为随机访问的参考点,可以当成图象.I帧可以看成是一个图像经过压缩后的产物: P frame: 前向预测编码帧,又称predictive-frame,通过充分将低于图像序列中前面已编码帧的时间冗余信息来压缩传输数据量的编码图像,也叫预测帧: B frame: 双向预测内插编码帧,又称bi-directio…

最近折腾intel media sdk,主要硬件平台是在HD4600的核显上进行测试,intel media sdk是intel提供的一种基于核显的硬件编解码的解决方案,之前已经有使用ffmpeg进行了测试,可以极大的降低CPU的使用情况.只与编解码出来的画质如何,并没有做多大的对比.从其官方文档来看,可以支持的近9路1080P(H264)的转码.但是对H265的支持,则需要专业版才行,通过so插件扩展的方式才能编解码成功.因此主要做的还是H264的编解码测试. 其提供的samples代码,是使…

http://blog.sina.com.cn/s/blog_4155bb1d0100soq9.html INTEL MEDIA SDK是INTEL推出的基于其内建显示核心的编解码技术,我们在播放高清视频时得益于这个硬解码,极大地降低了CPU占用率.除了解码,它还有编码功能,有硬件编码(SDK HARDWARE)和软件编码(SDK SOFTWARE),那么,INTEL的这个技术到底有多大能耐呢? 最新的小日本TMPGEnc Video Mastering Works 5的编码引擎可以分别调用IN…
