这个帖子是转贴:因为下列内容,没有再h264的标准上出现,所以要转, 我翻变了下列标准,都没有找到,希望网友告知我,这些内容到底在那个标准文档里面。
我已经翻阅的:
H.264官方中文版.pdf   
H.264和MPEG-4视频压缩.pdf 
H.264编解码手册.rar
T-REC-H.264-200503-S!!PDF-E.pdf

关于level_idc和Profile_IDC的解释

我在帖子上经常看到问题,现发表在这,大家可以参考一下:Class: Numeric (Integer)
Description: Set bitstream Profile IDC. Default is 88.

Note: Some profiles cannot support certain features. See MPEG-4 AVC for supported features for each profile. Reference software may perform tests for certain features for profile conformance, but it is possible that certain validations are missing. See Annex A of H.264/AVC.

Options:
66
Baseline
77
Main
88
Extended
100
High (FRExt)
110
High 10 (FRExt)
122
High 4:2:2 (FRExt)
144
High 4:4:4 (FRExt)

Class: Numeric (Integer)
Description: Set bitstream Level IDC. Default is 21.

Note: Similar with the ProfileIDC, LevelIDC sets certain restrictions during the encoding process, such as resolution supported, maximum number of references, frame rate etc. See Annex A of H.264/AVC.
