要获取H265的nal_unit_type,我们需要了解H265码流的结构,特别是NAL单元头部分,并编写代码来解析它。以下是基于你的提示的详细步骤和相应的代码片段: 1. 了解H265的nal_unit_type结构和作用 nal_unit_type是NAL单元头中的一个6位字段,用于标识NAL单元的类型。它决定了该NAL单元是哪种类型的数据,比如序列参数集...
由《音视频入门基础:H.264专题(4)——NALU Header:forbidden_zero_bit、nal_ref_idc、nal_unit_type简介》可以知道,nal_unit_type表示NALU的类型,在H.264官方文档《T-REC-H.264-202108-I!!PDF-E.pdf》第65页定义为: 二、NAL Unit Type 在RTP封包中,nal_unit_type被附加了扩展含义。根据《RFC 6184》第...
1. **NAL单元(NAL Unit)**:H.264编码的视频数据被分割成NAL单元,每个NAL单元是独立传输的最小单位。NAL单元的开始通常由一个起始码(通常是0x000001)标识。2. **NAL头**:每个NAL单元的第一个字节是NAL头,它包含了关于NAL单元的重要信息,如下所示: - **禁止位(F)**:1位,用于指示NAL单元中是否有比特...

2. The method according to claim 1, wherein each picture for each of the at least one of the one or more enhancement layer bitstreams has a same value of nal_unit_type as the picture of the base layer bitstream.Description: CROSS-REFERENCE TO RELATED APPLICATIONS None. BACKGROUND OF THE...
type for slices in a picture may be determined on the basis of NAL unit type-related information relating to whether the picture has a mixed-NAL unit type, and a type mixed with another type of NAL unit as well as an IRAP for a picture having the mixed-NAL unit type may be provided...
NAL unit type restrictionsA system for encoding and/or decoding video that include NAL unit types.doi:US20140301451 A1Sachin G. DeshpandeUS
A method includes receiving a first network abstraction layer (NAL) unit of a first slice of a coded picture and a second VCL NAL unit of a second slice of the coded picture, the first VCL NAL unit having a first VCL NAL unit type and the second VCL NAL unit having a second VCL ...
With current H.264/AVC, scalable video coding (SVC), and multi-view coding (MVC), a redundant coded slice can be identified by parsing a slice header. However, the parsing of the slice header aggravates the burden on a processor and increases costs. A NAL unit type is used to indicate...
