Compile ffmpeg for iOS 6, support Simulator & armv7 & armv7s

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:

git clone [e-mail]:lvjian700/ffmpegc.git
cd ffmpegc
./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:

[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 ...

可以运行，但是没有声音，是否是声音未解码，还是我编译的有问题

只做了图像解码。 声音你要自己研究了。
推荐项目: https://github.com/kinglonghuang/kxmovie (编译好后可以直接用他的静态库)

请问一下，似乎编译不出 libswresample.a 这个库，kxmovie 要用到。怎么解决啊？

我的没有编译libsresample.a这个库

看这个工程, 用他自己的编辑脚本。
