This is an example that demonstrates how to transcode mp4 to flv using Xuggler. This is a very easy and common transcoding.
To do that, one should follow these basic steps:
- Create a
IMediaReaderto read the video file. - Create an
IMediaWriterusingToolFactory.makeWriter. - Add a writer to the reader, to create the output file
- Create a
IMediaViewerwith stats enabled - Add a viewer to the reader, to see the decoded media
- Read and decode packets from the source file and dispatch decoded audio and video to the writer .
Let’s see the code:
package com.javacodegeeks.xuggler;
import com.xuggle.mediatool.IMediaReader;
import com.xuggle.mediatool.IMediaViewer;
import com.xuggle.mediatool.IMediaWriter;
import com.xuggle.mediatool.ToolFactory;
public class TranscodingExample {
private static final String inputFilename = "c:/myvideo.mp4";
private static final String outputFilename = "c:/myvideo.flv";
public static void main(String[] args) {
// create a media reader
IMediaReader mediaReader =
ToolFactory.makeReader(inputFilename);
// create a media writer
IMediaWriter mediaWriter =
ToolFactory.makeWriter(outputFilename, mediaReader);
// add a writer to the reader, to create the output file
mediaReader.addListener(mediaWriter);
// create a media viewer with stats enabled
IMediaViewer mediaViewer = ToolFactory.makeViewer(true);
// add a viewer to the reader, to see the decoded media
mediaReader.addListener(mediaViewer);
// read and decode packets from the source file and
// and dispatch decoded audio and video to the writer
while (mediaReader.readPacket() == null) ;
}
