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

n 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


git clone git@github.com: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:

Java代码


git@github.com: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 ...
