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 git@github.com:lvjian700/ffmpegc.git cd ffmpegc ./install-ffmpeg.shhttps://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:
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:
