# Java Media Framework

From Sun JMF site: "The Java Media Framework API (JMF) enables audio, video and other time-based media to be added to applications and applets built on Java technology. This optional package, which can capture, playback, stream, and transcode multiple media formats, extends the Java 2 Platform, Standard Edition (J2SE) for multimedia developers by providing a powerful toolkit to develop scalable, cross-platform technology."

## Installation

Install jmfAUR[broken link: archived in aur-mirror] from AUR.

## Configuration

In order to setup JMF for the first time (to recognize audio and capture devices) you will need to run as root:

    jmfinit

(An active X11 session is needed)

### JMFRegistry

You can manually setup JMF (GUI) running as root:

    jmfregistry

JMFRegistry User's Guide

## Adding audio/video codecs support to JMF

### Sun MP3 Plugin

Sun MP3 Plugin is included in the JMF package and installed by default with it.

If there is any trouble you can reinstall the MP3Plugin running as root:

    jmfRegisterMp3Plugin

### JFFMpeg

"Jffmpeg is a plugin that allows the playback of a number of common audio and video formats. It is based around a Java port of parts of the FFMPEG project, supporting a number of codecs in pure Java code. Where codecs have not yet been ported, a JNI wrapper allows calls directly into the full FFMPEG code."

Install jffmpegAUR[broken link: archived in aur-mirror] from AUR.

The install script will register the plugins and associate the mimetypes in the JMF registry and the uninstall script will unregister the plugins from the JMF registry.

#### Reinstalling JMF and JffMpeg

If you reinstall JMF you will have to run as root:

    jmfRegisterJffmpegPlugin

in order to register again all the jffmpeg plugins in the JMF registry

## Testing JMF capabilities

A demo player is available to test JMF audio/video playback capabilities.

    java JMStudio

You can also check if JMF is properly installed in: http://ku-prism.org/virtualprism/explorations/JavaTest/javatestpage.html (it currently works on Firefox2/3 and Opera)

If your JMF installation is OK you should get something like:

    JMF Version... 2.1.1e
    All Java Build
    Native Libraries Found
