Two processors, one becomes unresponsive..

Question

Hello all,
I'll try to keep it to the very basics, otherwise we may get lost in the details.
I have two classes; WebcamImageGrabber & WebcamStreamer.
Both are to be constructed with a DataSource as argument and create a processor.
The WebcamImageGrabber is a Thread and basically gets the stream and converts it to a still image and updates a JLabel.
The WebcamStreamer sets up a DataSink to stream with.
Both classes use the FormatControl[]'s to set the tracks to a desired format; the WebcamImageGrabber for the image size and such, and the WebcamStreamer for streaming format (currently VideoFormat.H263_RTP, though I need to sort out if that's the propper one).
Both classes work but only if one of them is disabled. Apparently, the other class's functionality is broken when a class Configure() it's own processor.
No errors, no warnings. Hmm.
I wonder if it's even possible to have two Processors, or, if it's desireable at all.
Now, I searched these forums but all I found were a lot of unanswered threads.
Are these forums dead? Am I looking in the wrong place? Anyone who knows, please do tell.
Thanks in advance,
Onno

Answer 1

Ah, yes, I see now.
I've modified my code as following:
The class that initializes (or rather, 'finds' it) the webcam and sets up a private datasource now has this method:
public DataSource getRawDataSource() {
     return ((SourceCloneable)this.ds).createClone();
}this.ds is initialized in the constructor like this:
public Webcam() {
        dataSource = Manager.createDataSource(loc);
        this.ds = Manager.createCloneableDataSource(dataSource);
}When using a cloned datasource, neither streaming or the grabbing works.
Grabbing locks up at stream.read(b);
Any ideas?
