Installing Ffmpeg iOS Libraries Armv7, Armv7S, I386 and Universal on MAC with 10.8

Installing ffmpeg ios libraries armv7, armv7s, i386 and universal on Mac with 10.8

After a couple of days I have made step by step instructions for this install:

FFmpeg Build Instructions MAC 10.8 or better

Copy ffmpeg-2.0.tar.bz2 (https://ffmpeg.org/releases/ffmpeg-1.0.7.tar.bz2, https://ffmpeg.org/download.html) and Unzip to Documents folder

Make sure you have the latest Command Line Tools under Xcode >; Preferences >; Downloads >; Components

Install gas-preprocessor

1. Click on the ZIP icon to download https://github.com/mansr/gas-preprocessor.
2. Copy gas-preprocessor.pl to /usr/bin directory.
3. Change permission of gas-preprocessor.pl by setting the privilege to Read & Write for all.

Bug in xcrun starting in version 10.8

open terminal and paste in following command and press enter:

export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"

cd to ffmpeg-2 folder and paste in following command and press enter:

mkdir armv7
mkdir armv7s
mkdir i386
mkdir -p universal/lib

To config armv7s library paste in following command and press enter:

./configure --prefix=armv7s --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.1" --extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1" --arch=arm --cpu=cortex-a9 --enable-pic

(Note same rule as above: if config fails go to
Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
and make sure that the sdk folder is iPhoneOS6.1.sdk, if not change
the config command to reflect iPhoneOSx.x.sdk and change all targets
to x.x)

To build and install armv7s library paste in following command and press enter:

make clean && make && make install

To config i386 (so simulator will work ) library paste in following command and press enter:

./configure --prefix=i386 --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc" --extra-cflags="-arch i386" --extra-ldflags="-arch i386 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk" --arch=i386 --cpu=i386 --enable-pic --disable-asm

(Note: this is not the same command as the previous two config
commands, if you just arrow up to them this will fail)

To build and install i386 library paste in following command and press enter:

make clean && make && make install

To make universal library ( which is the library added to xcode ) paste in following command and press enter:

cd armv7/lib
for file in *.a
do
cd ../..
xcrun -sdk iphoneos lipo -output universal/lib/$file  -create -arch armv7 armv7/lib/$file -arch armv7s armv7s/lib/$file -arch i386 i386/lib/$file
echo "Universal $file created."
cd -
done
cd ../..

Building ffmpeg iOS libraries for armv7, armv7s, arm64, i386 and universal

I have use below scripts for making FFmpeg build for arm64

https://github.com/kewlbear/FFmpeg-iOS-build-script

https://github.com/bbcallen/ijkplayer/blob/fc70895c64cbbd20f32f1d81d2d48609ed13f597/ios/tools/do-compile-ffmpeg.sh#L7

You have to add libbz2.dylib and libiconv.dylib framework in your xCode project.

To use the mooncatventures (our) ffmpegdecoderFramework, go into build settings
click on the arch and remove the armv7s.

you must also change build active architechure only to no.

How to include FFMpeg library in iphone project

Well you could have a look at the following links

And this tutorial

easiest ways to convert a mac osx app to an ios app

There's no silver bullet for this; it has to be done by hand.

You can probably reuse some of the "model" code, since both Mac and iOS use an MVC pattern, but the "view" code has to be written basically from scratch.
