Getting Started with FFMPEG-Java
Note : FFMPEG-Java is not the same thing as Jffmpeg. FFMPEG-Java is a sub-project of
Freedom for Media in Java, FMJ in short.
This project is licensed under the LGPL. It has optional GPL components for using FFMPEG's GPL swscale library.
If you wish to use swscale and the GPL, use ffmpeg-java-gpl.jar. The standard LGPL jar for this project
FFMPEG-Java is a Java wrapper around FFMPEG, using JNA. It assumes that dynamic libraries for FFMPEG have been compiled, and are in your library path.
Note : mmx is disabled in this example, as it has caused problems in the past.
Step 1 : Get FFMPEG sources from http://ffmpeg.mplayerhq.hu
Step 2 : Build/install FFMPEG
./configure --disable-mmx --enable-shared
sudo make install
Step 3 : Run one of the sample programs with a media file as the first parameter.
In several *nix systems, sometimes have to set your library path explicitly. For example :
Plays a movie in a window :
java -cp ./ffmpeg-java.jar:./lib/jna.jar net.sf.ffmpeg_java.example.PlayerExample http://www.javasaver.com/testjs/jmf/anim/2005-11-26.mov
Creates 5 ppm files in the current directory with the first 5 frames of the movie :
java -cp ./ffmpeg-java.jar:./lib/jna.jar net.sf.ffmpeg_java.example.AVCodecSample http://www.javasaver.com/testjs/jmf/anim/2005-11-26.mov
Very good documentation how to setup build environment - msys and mingw - and how to build FFMPEG on Windows can be found in here. The FFMPEG builts provided there have worked too, but some image codecs/formats were missing.
