An {@link IMediaCoder} that reads and decodes media from an{@link IContainer}.

An {@link IMediaReader} opens up a media container,reads packets from it, decodes the data, and then dispatches information about the data to any registered {@link IMediaListener} objects. The main method ofinterest is {@link #readPacket()}.

Here's an example of a very simple program that prints out a line when the {@link IMediaReader} decides to open a container.

 IMediaDebugListener myListener = new MediaListenerAdapter(){ public void onOpen(IMediaGenerator pipe) { System.out.println("opened: " + ((IMediaReader)pipe).getUrl()); } }; IMediaReader reader = ToolFactory.makeReader("myinputfile.flv"); reader.addListener(myListener); while(reader.readPacket() == null) ;

And here's a slightly more involved example where we read a file and display it on screen in real-time:

 IMediaReader reader = ToolFactory.makeReader("myinputfile.flv"); reader.addListener(ToolFactory.makeViewer()); while(reader.readPacket() == null) ;

    File outputFile = new File(args[1]);


    // create a media reader and configure it to generate BufferImages


    IMediaReader reader = ToolFactory.makeReader(inputFile.toString());
    reader.setBufferedImageTypeToGenerate(BufferedImage.TYPE_3BYTE_BGR);


    // create a writer and configure it's parameters from the reader
    
    IMediaWriter writer = ToolFactory.makeWriter(outputFile.toString(), reader);


    // create a tool which paints video time stamp into frame


    IMediaTool addTimeStamp = new TimeStampTool();


    // create a tool which reduces audio volume to 1/10th original


    IMediaTool reduceVolume = new VolumeAdjustTool(0.1);


    // create a tool chain:
    //   reader -> addTimeStamp -> reduceVolume -> writer


    reader.addListener(addTimeStamp);
    addTimeStamp.addListener(reduceVolume);
    reduceVolume.addListener(writer);


    // add a viewer to the writer, to see media modified media
    
    writer.addListener(ToolFactory.makeViewer());


    // read and decode packets from the source file and
    // then encode and write out data to the output file
    
    while (reader.readPacket() == null)
      do {} while(false);
