HEVC:High Efficiency Video Coding,是个通称,相对于上一代的AVC(高级视频编码),意译为(高效率视频编码)
以HEVC编码的视频有个PROFILE,有不同的LEVEL,这个LEVEL定义了此视频的最大参数的上限。LEVEL从1到6.2不等共十三级用于不同用途,你可以理解为拳击比赛里的羽量级,重量级等等。
此视频标准还切分为2种,MAIN和HIGH,其中LEVEL 4以下只能定义为MAIN。简略理解为高低码率区别即可。
The HEVC standard defines two tiers: Main and High. The Main tier is a lower tier than the High tier.The tiers were made to deal with applications that differ in terms of their maximum bit rate.The Main tier was designed for most applications while the High tier was designed for very demanding applications.
profile:main 10,level:5.1,这个定义是家用视频里最常见的,通俗理解为低TIER里第十级即可。
