编译ffmpeg for x264 ，H264编码解码

In the posts, I will show how to use ffmpeg on iOS.

 

This posts is a document for this project: 

https://github.com/lvjian700/ffmpegc-demo

 

Now, ffmpec support x264 module. If you use the script before, please check your version first. 

 

What is ffmpeg ?

FFmpeg is a complete, across-platform solution to record, convert and stream audio and video. 

Why use ffmpeg?

• Play h.264 video
• encoding capture video to h.264 video(It need ffmpeg h.264 module.)
• publish a av stream
• subscribe a rtsp av stream

Before use ffmpegc-demo, you should download and compile ffmpeg:

I made a repository to make the step easy:

Shell代码  

1. git clone [e-mail]:lvjian700/ffmpegc.git  
2. cd ffmpegc  
3. ./install-ffmpeg.sh  

 https://github.com/lvjian700/ffmpegc

If compile complete, you can find universal library in ffmpeg/build folder:

1. ffmpeg core library:

 

2. ffmpeg x264 module. x264 is a H.264/MPEG-4 AVC encoder 

 

Using ffmpeg

1. Clone project first:

Java代码  

1. [e-mail]:lvjian700/ffmpegc-demo.git  

2.Open in XCode and copy build/*.a and x264/build/*.a to libs/ folder of the project:

 

3. Add them to project link library

Project References -> Targets -> Build Phases -> Link Binary With Librarys

 

4. Add dependences library:

Project References -> Targets -> Build Phases -> Link Binary With Librarys

Add two library:

• libbz.dylib
• libz.dylib
• libiconv.2.4.0.dylib

 

5. Add Header Search Paths:

Project References -> Targets -> Build Settings -> Header Search Paths

1. add ffmpeg core header paths:

 

2. add x264 header paths:

 

 

 

6. Now, run project ...

 

Some useful document:

《How to prepare your mac for ios development with ffmpeg libraries》

《ffmpeg configure options》 -pdf

最后要个.sh里加上     --enable-encoder=libx264    才可以
