It took me nearly three weeks to implement HTTP live streaming on the crtmpserver to package h264 and aac into ts streams and play them on the iPad through HTML5, because there is no ready-to-useCodeFor reference, the packaging code is all handwritten. For the packaging format, refer to ISO/ice 18318-1.pdf. During this period, I encountered many problems and took a lot of detours.

This article describes one of the simplest audio encoders based on FFmpeg. The encoder realizes the PCM audio sampling data encoded as AAC compressed encoded data. The encoder code is very simple, but each line of code is important. By looking at the source code of this encoder, you can understand the FFmpeg audio coding process. This program uses the latest version of the class library (compile time is 2014.5.6), the development platform for VC2010.
