A FFMPEG build for windows phone runtime.

#FFMPEG for Windows Phone

FFMPEG_WindowsPhone consists of:

• FFmpeg v2.4 for Windows Phone 8.0+
• A .NET Windows Runtime Component that exposes FFmpeg as an API for use by Windows Phone applications

To get started right away with the .NET Windows Runtime Component, simply:

1. Add FFMPEGRuntime as a reference in your Windows Phone project.

2. Create an instance of FFMPEGRuntime.

3. Invoke the Run() method, passing whatever command-line arguments you'd like (see the [FFmpeg documentation] (https://ffmpeg.org/ffmpeg.html) for more details). The FFMPEGDemo application provides an example usage.

For convenience, this repo includes all native library dependencies including the debug and release binaries of FFmpeg (built for Windows Phone ARM). However, if you'd prefer, you can build the FFmpeg native libraries yourself by following the instructions below.

Prerequisites

1. Visual Studio 2012 with Update 2

2. MinGw + MSYS (http://www.mingw.org/).

3. Install c99-to-c89-1.0.3 and add the location to the PATH environment variable.

4. Install vsyasm-1.3.0-win64 and add the location to the PATH environment variable.

5. Download gas-preprocessor.pl (https://github.com/FFmpeg/gas-preprocessor), and copy it into msys bin folder.

6. zlib library that is required for png support is already checked-in to the 3rd Party folder. The current version of the library is obtained from Nuget Package Manager: https://www.nuget.org/packages/zlib_wp8/

External dependencies ( c99-to-c89-1.0.3  +  vsyasm-1.3.0-win64 + gas-preprocessor.pl)  used for building the currently checked-in libraries are stored in ffmpeg-dependencies.zip 

Building

1. cd into ffmpeg folder

2. Apply the patches from Git command line client by invoking:

./applyPatches.sh

3. Open "VS2012 ARM Cross Tools Command Prompt"

4. Start an msys window by invoking: C:/MinGw/msys/1.0/bin/msys.bat

5. Using the newly opened msys+mingw window, change directory to ffmpeg.2.4:

cd ffmpeg/ffmpeg.2.4

6. Invoke the build script (no option means debug):

./build_ffmpeg_msvc.sh

If the build fails due to duplicate link.exe in msys, need to rename msys version of link.exe so that the visual studio link.exe is used.

7. In order to build in release mode:

./build_ffmpeg_msvc.sh release

8. For a quick build without re-configuring:

./build_ffmpeg_msvc.sh quick

9. Output static libraries will be stored in ffmpeg/build/<debug/release> folder

Currently checked-in ffmpeg.2.4.tar is derived from https://github.com/qyljcy/FFmpeg
