MediaConch_SourceCode README

MediaConch is an open source software project consisting of a toolset that aims to further develop the standardization and validation of preservation-level audiovisual files used within various memory institutions and communities. The software consists of an implementation checker, policy checker, reporter and fixer that will work together to offer its users an advanced level of ability to validate, assess and find solutions to repair the digital files within their collections. Accessible via either the command line, a graphical user interface (GUI), or web-based shell, the MediaConch project will serve to provide detailed individual and batch-level conformance checking analysis using its adaptable, flexible and interoperable software application interface. With a project focus dedicated to furthering the longevity of Matroska, Linear Pulse Code Modulation (LPCM) and FF Video Codec 1 (FFV1) as recommended digital preservation audiovisual formats, MediaConch will anticipate and contribute to the further development of the standardization of these formats. The MediaConch open source project was created and is currently under development by MediaArea, notable for the creation of MediaInfo, an open source media checker software application.

How to build MediaConch

Build under Unix (Mac and Linux)

First, you must create a directory which will receive the MediaConch directory, and some of its dependencies depending on your configuration: ZenLib and MediaInfoLib if you decide to compile them yourself, and under Mac libxml2 and libxslt.

In this document, this directory will be referred as $BUILD_DIR.

Dependancies under Mac

Build MediaConch CLI

Use the srcXX.zip and their compile.sh scripts

Unzip the corresponding srcXX.zip, and then launch

./CLI_compile.sh
./Server_compile.sh
./GUI_compile.sh

in order to compile, respectively, the CLI, the server and the GUI.

Build manually from GitHub

When you have done all the prerequisite for you configuration, you can build MediaConch. We start with the CLI.

cd $BUILD_DIR
git clone https://github.com/MediaArea/MediaConch_SourceCode.git
cd MediaConch_SourceCode/Project/GNU/CLI
./autogen.sh

Then, under Mac:

./configure --enable-staticlibs
make

Under Linux:

./configure
make

If you also build ZenLib and MediaInfoLib:

./configure --enable-staticlibs
make

Or, with shared ZenLib and MediaInfoLib:

./configure
make
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$BUILD_DIR/ZenLib/Project/GNU/Library/.libs:$BUILD_DIR/MediaInfoLib/Project/GNU/Library/.libs

Launch the CLI

./mediaconch

Build MediaConch GUI

If you have already build the CLI, no need to run git twice. In fact, if you re-run git with an existing MediaConch_SourceCode directory, git will complain and exit.

To compile MediaConch GUI under Mac and Linux:

cd $BUILD_DIR
git clone https://github.com/MediaArea/MediaConch_SourceCode.git
cd MediaConch_SourceCode/Project/Qt

Without online checker

Run:

./prepare
make

Under Mac, or if you also build ZenLib and MediaInfoLib, run:

./prepare STATIC_LIBS=1
make

With shared ZenLib and MediaInfoLib:

./prepare
make
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$BUILD_DIR/ZenLib/Project/GNU/Library/.libs:$BUILD_DIR/MediaInfoLib/Project/GNU/Library/.libs

With online checker

You must install the online checker dependencies. Then run:

./prepare
make

Under Mac, or if you also build ZenLib and MediaInfoLib, run:

./prepare STATIC_LIBS=1
make

With shared ZenLib and MediaInfoLib:

./prepare
make
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$BUILD_DIR/ZenLib/Project/GNU/Library/.libs:$BUILD_DIR/MediaInfoLib/Project/GNU/Library/.libs

Launch the GUI

Under Mac:

./MediaConch.app/Contents/MacOS/MediaConch

Under Linux:

./mediaconch-gui

Optional : build ZenLib and MediaInfoLib

ZenLib

To compile ZenLib under Mac and Linux:

cd $BUILD_DIR
git clone https://github.com/MediaArea/ZenLib.git
cd ZenLib/Project/GNU/Library
./autogen.sh
./configure --enable-static
make

MediaInfoLib

To compile MediaInfoLib under Mac and Linux:

cd $BUILD_DIR
git clone https://github.com/MediaArea/MediaInfoLib.git
cd MediaInfoLib/Project/GNU/Library
./autogen.sh

Without online checker

Run:

./configure --enable-static
make

With online checker

Under Mac:

./configure --enable-static --with-libcurl=runtime
make

Under Linux:

You must install the online checker dependencies. Then run:

./configure --enable-static --with-libcurl
make

Build under Windows

You need to install Microsoft Visual Studio 2013.
