1..This is the code which we used for capturing and saving video in the disk..But we got a mov file created zero size..what is the reason for that..Can any one suggest a better way for this..
2..Is Creative Webcam II supported by JMF 2.1 ..
3..Suggest any other format for audio and video capturing and saving..
Thanks in advance..

Answer 1

Thanks T.B.M..
It worked..My webcam details are as follows:
{color:#ff6600}Name = vfw:Microsoft WDM Image Capture (Win32):0
Locator = vfw://0
{color}
It suports the following formats..
{color:#ff6600}
0. javax.media.format.RGBFormat
RGB, 320x240, Length=230400, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=960, Flipped
1. javax.media.format.RGBFormat
RGB, 160x120, Length=57600, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=480, Flipped
2. javax.media.format.RGBFormat
RGB, 176x144, Length=76032, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=528, Flipped
3. javax.media.format.RGBFormat
RGB, 352x288, Length=304128, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=1056, Flipped
4. javax.media.format.RGBFormat
RGB, 640x480, Length=921600, 24-bit, Masks=3:2:1, PixelStride=3, LineStride=1920, Flipped
{color}
So made the following changes in my code..
dl=CaptureDeviceManager.getDeviceList(new VideoFormat(VideoFormat.{color:#ff6600}RGB{color}));
ml=((CaptureDeviceInfo)dl.firstElement()).getLocator();
formats=new VideoFormat(VideoFormat.RGB);
model = new ProcessorModel(ml,new Format[]{formats}, new FileTypeDescriptor(FileTypeDescriptor.{color:#ff6600}MSVIDEO{color}));
p=Manager.createRealizedProcessor(model);
source=p.getDataOutput();
sink = Manager.createDataSink(source, new MediaLocator("file:///c:/Adiyae.{color:#ff6600}avi{color}"));
p.addControllerListener(this);
p.realize();
Now the file is getting created with its size depending upon how long i capture..This is fine..But when i try to play the file using a media player it doesnt open.. when i tried opening it with JMStudio i get the following message..
{color:#ff6600}Controller Error:
Failed to realize:Failed to parse the input media..
{color}Also can you tell me how to choose the FileTypeDescriptors for a particular video format.. The only FileTypeDescriptor that works with mine is the MSVIDEO..
Thanks in advance..
