Based on the analysis of the FLV format in the previous article, the FLV format includes file header and file body. Therefore, you can define file header and previous tag size #0 as follows: Const static unsigned char flvfilehdr [] = {0x46, 0x4c, 0x56, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0x00}; The file body consists of the tag header and tag data. Therefore, the tag header can be defined as follows: Unsigned char flvtaghdr [] = {0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0 x, 0x00}; Note:
