Adding WaterMarks/Text to live stream with Vp6

[Annie]

Hi All,
1. I need to ask if there is any encoder which can transcode live
stream from flash in SorensenSpark?Nelly Moser format to VP6 with
water marks

2.Is it possible to add watermarks(images/text) to stream in Vp6 ?


Thanks

People say that with xuggler it is possible. I am also on the same
track.

Thanks
But I have read that Xuggler doesnt support VP6

Xuggler doesn't support encoding VP6, that's true.  You can encode to SorensenSpark or H264 and you can add WaterMarks.

And before Prassad says so, no, we don't have the exact code you need already written for you, but review the tutorials and demo code, get familiar with the Java AWT image library, and you should be able to figure it out.

Hmm, I have a bad reputation.

Add a watermark is kind easy!!! if you look into examples you might
see you have almost all that you need to perform it!

Simple solution:D



public static void main(String[] args) throws IOException{
if (args.length < 2){
System.out.println("Usage: ModifyAudioAndVideo <inputFileName>
<outputFileName>");
System.exit(-1);
}

File inputFile = new File(args[0]);

if (!(inputFile.exists())){
System.out.println("Input file does not exist: " + inputFile);
System.exit(-1);
}

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

IMediaReader reader = ToolFactory.makeReader(inputFile.toString());
reader.setBufferedImageTypeToGenerate(5);

IMediaWriter writer = ToolFactory.makeWriter(outputFile.toString(), reader);


File waterMarkFile = new File("pearls-watermark.png");
BufferedImage waterMark = ImageIO.read(waterMarkFile);
IMediaTool addWatermark = new WatermarkTool(waterMark);

reader.addListener(addWatermark);
addWatermark.addListener(writer);

//show conversion result window
writer.addListener(ToolFactory.makeViewer());

while (reader.readPacket() == null);

}


static class WatermarkTool extends MediaToolAdapter{

BufferedImage waterMark = null;

private static final int __WATERMARK_WIDTH = 100;
private static final int __WATERMARK_HEIGHT = 50;

public WatermarkTool(BufferedImage waterMark) {
this.waterMark = waterMark;
}


public void onVideoPicture(IVideoPictureEvent event){

BufferedImage image = event.getImage();
Graphics2D g = image.createGraphics();


g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER,
0.4f));// 40% transp
g.drawImage(waterMark, image.getWidth() - waterMark.getWidth(),
image.getHeight() - waterMark.getHeight(), null);// draw in lower
right corner

//Image watermarkLogo =
waterMark.getScaledInstance(__WATERMARK_WIDTH, __WATERMARK_HEIGHT, 0);
//g.drawImage(watermarkLogo, image.getWidth() - __WATERMARK_WIDTH,
image.getHeight() - __WATERMARK_HEIGHT, null);// draw in lower right
corner

super.onVideoPicture(event);

Thankyou All,

Just need to know that Is it possible to add water mark to the
stream in VP6 format?
Which encoder does it best

Thanks

[Art Clarke]

As far as I know, ON2 makes the only available (and commercial) VP6 encoder, but you need to use their software APIs to use it.  We have not integrated ON2 with Xuggler.
