从sdp中的profile-level-id中识别h264配置文件和级别？

如何识别约束实际意味着什么？例如,我有一个profile-type-id: 42801e转换为:

我如何将其与此处表格中定义的功能相关联？

上述参考文献确定,这Constraint_set0_flag: 1意味着它是约束基线轮廓.但是如何将旗帜与三个不同的NO(来自表格)相关联,以区分基线轮廓和约束基线轮廓？

无法确认上述,关于识别Constrained Baseline profile,是否正确.该声明的参考(第306页):

Decoders conforming to the Constrained Baseline profile at a 
specific level shall be capable of decoding all bitstreams 
in which all of the following are true:

– profile_idc is equal to 66 or constraint_set0_flag is equal to 1,
– constraint_set1_flag is equal to 1, 
– level_idc and constraint_set3_flag represent a level 
less than or …
