README
------
- This document provides a description of the MLT project organisation.
-
- It provides *CRITICAL* architecture information, so please read carefully
- if you plan to extend or use the MLT code base.
-
-Directories
------------
-
- The directory heirarchy is defined as follows:
-
- + docs - Location of all documentation
- + src - All project source is provided here
- + framework - The mlt media framework
- + modules - All services are defined here
- + core - Independent MLT services
- + dv - libdv dependent services
- + ffmpeg - ffmpeg dependent services
- + avformat - libavformat dependent services
- + vorbis - vorbis dependenent services
- + sdl - SDL dependent services
- + resample - libresample dependent services
- + gtk2 - pango and pixbuf dependent services
- + xine - xine-derived services
- + bluefish - Bluefish dependent services (*)
- + mainconcept - mainconcept dependent services (*)
- + inigo - A media playing test application
- + valerie - Client API to access the server
- + miracle - The server implementation
- + humperdink - The evil demo
- + albino - The simple but nice demo
- + tests - Reserved for regression and unit tests
-
- Additional subdirectories may be nested below those shown and should be
- documented in their parent.
-
- (*) Not posted to CVS due to licensing issues.
+ This document provides a quick reference for the minimal configuration,
+ build and installation of MLT.
Configuration
-------------
- Configuration is triggered from the top level directory via a
- ./configure script.
-
- Each source bearing subdirectory shown above have their own configure
- script which are called automatically from the top level.
+ Configuration is triggered by running:
- Typically, new modules can be introduced without modification to the
- configure script and arguments are accepted and passed through to all
- subdirectories.
+ ./configure
- Top level usage is:
+ Usage is:
./configure --help - report all configure options
./configure --prefix=[dir] - target install directory (default: /usr/local)
Compilation
-----------
- Makefiles are generated during configuration and these are based on
- a per directory template which must be provided by the developer.
+ Once configured, it should be sufficient to run:
+
+ make
+
+ to compile the system.
Testing
-------
To execute the mlt tools without installation, or to test a new version
on a system with an already installed mlt version, you should run:
- . setenv
+ . setenv
- NB: This applies to your current shell only.
+ NB: This applies to your current shell only and it assumes a bash or
+ regular bourne shell is in use.
Installation
------------
- * NOT IMPLEMENTED YET *
-
- The install is triggered by running make install or make install-strip
- from the top level directory.
-
- The framework produces a single shared object which is installed in
- $prefix/lib/ and public header files which are installed in
- $prefix/include/mlt/framework.
-
- The client produces a single shared object which is installed in
- $prefix/lib/ and public header which are installed in
- $prefix/include/mlt/client.
-
- The server produces a single exectuable which is installed in
- $prefix/bin/. This is linked against the framework shared object and
- posix libs but not against any of the modules.
-
- The modules produce a shared object per module and update text files
- containing a list of modules provided by this build. These are installed
- in $prefix/share/mlt/. It is at the discretion of the module to install
- additional support files.
+ The install is triggered by running:
- To allow the development of external components, mlt-client-config and
- mlt-framework-config scripts are generated and installed in $prefix/bin.
-
- After install, only those modules listed are usable by the server. No
- module is loaded unless explicitly requested via server configuration
- or usage.
-
- External modules are also placed in this $prefix/share/mlt, and the
- installation of those must modify the text file accordingly before they
- will be considered at runtime.
-
-Development
------------
-
- All compilation in the project has {top-level-dir}/src on the include path.
- All headers are included as:
-
- #include <framework/file.h>
+ make install
- All external modules have {prefix}/include/mlt on the include path. All
- headers should also be included as:
-
- #include <framework/file.h>
- This allows migration of source between external and internal modules.
- The configuration and Makefile template requirements will require
- attention though.
-
-Summary
--------
+More Information
+----------------
- 1. The server will interact with public interfaces from the framework only;
- 2. The modules must expose public framework interfaces only;
- 3. All modules are dynamically loaded at runtime.
+ For more detailed information, please refer to docs/install.txt.
