1. mux 相关函数逻辑 - write header 如图 2. mux 相关函数逻辑 mux 层给我最直观的感觉就是比较“碎”,最上层用户接口的与内部实现几乎结成了一个“网状结构”,这也代表很多函数都是可以复用的。 简要描述一下几个内部实现函数的各自目的,以防在正式解读 mux 用户接口时,内部互相调来调去难以理解。 Mux 相...

简单的说，ffmpeg有视频采集功能、视频格式转换、视频抓图、给视频加水印 值得注意的是，ffmpeg只是提供了编码解码的接口。decode--译码，解码工具 如：H264 decode encode--解码 值得一提的是：encode+decode=codec（编码方式）demux是“解析格式”，比如MKV，MOV是格式（专业的叫法是容器）格式内有stream...

I tracked the ffmpeg code and found that in the function "av_write_frame->mov_write_packet->ff_mov_write_packet", it will call function "ff_avc_parse_nal_units" to obtain the size of nal unit, but the return value is very small(such as 208 bytes). ...
