Introduction

This project is forked from https://github.com/lajos/iFrameExtractor. I update the code for the latest ffmpeg and iOS version. The source code is tested on

Mac OS 10.7.4(Lion)
for
ffmpeg 0.11.1
and
iOS 5.1
with
Xcode 4.3.2
.

Build steps

  • Download the code using

git clone git://github.com/PinkyJie/iFrameExtractor.git
  • Download the latest ffmpeg (0.11.1 tested) using

git clone git://source.ffmpeg.org/ffmpeg.git
  • Put the ffmpeg source code into the folder

    ffmpeg
  • Copy the perl script

    gas-preprocessor.pl
    into
    /usr/local/bin
    folder
  • Change directory to your

    ffmpeg
    folder, select your target platform and follow the scripts below
