Frame rate = One picture in 5 seconds?

Question

Hi, I am capturing video from a web cam in rgb. I want to send only one picture in five seconds across the network (Frame Rate = 0,2). This does not seem to work. My code:
          Object frameRate = processor.getControl("javax.media.control.FrameRateControl");
          if(frameRate != null)
Logger.getInstanceOf().writeLog(Constants.LOG_INFO, this.getClass(), "createProcessor()", "Current frame rate is: " + String.valueOf(((FrameRateControl) frameRate).getFrameRate()) + " frames per second ...");
          FrameRateControl frc = (FrameRateControl) frameRate;
          frc.setFrameRate(0.2f);
Logger.getInstanceOf().writeLog(Constants.LOG_INFO, this.getClass(), "createProcessor()", "New frame rate is: " + String.valueOf(((FrameRateControl) frameRate).getFrameRate())+ " frames per second ...");
It seems as if I can only reduce the Frame Rate to 5. I am using a H263 video format. Does anybody know how to further reduce the frame rate?

Answer 1

Hi, I found the answer myself.
When you capture with RGB in Frame Rate 15 and 320x240 Dimensions and you want to transmit using H263, you can only reduce the Frame Rate to 5 FPS. I do this using the code above on a realized player. When you want to further reduce the frame rate you need to create a second processor taking the H263 Stream with 5 FPS as input. Using the code above on the second realized processor enables you to further reduce the Frame Rate.
This worked for me.
I also used the following code WITH NO SUCCESS:
     Format checkForVideoSizes(Format original, Format supported) {
          int width, height;
          Dimension size = ((VideoFormat) original).getSize();
          Format jpegFmt = new Format(VideoFormat.JPEG_RTP);
          Format h263Fmt = new Format(VideoFormat.H263_RTP);
          return (new VideoFormat(VideoFormat.H263_RTP, new Dimension(width, height),
                    Format.NOT_SPECIFIED, null, Format.NOT_SPECIFIED))
                    .intersects(supported);
Anyway ... the problem is solved.
