| Methods Summary |
|---|
| public void | close()Closes the plug-in component and releases resources. No more data
will be accepted by the plug-in after a call to this method. The
plug-in can be reinstated after being closed by calling
open.
if (source != null) {
try {
source.stop();
// stop each of the tracks, so that readFrame() can be
// released.
for (int i = 0; i < tracks.length; i++)
((FrameTrack)tracks[i]).stop();
source.disconnect();
} catch (IOException e) {
// Internal error?
}
source = null;
}

return NAME;

| public javax.media.Track[] | getTracks()
return tracks;
|
| public void | open()Opens the plug-in software or hardware component and acquires
necessary resources. If all the needed resources could not be
acquired, it throws a ResourceUnavailableException. Data should not
be passed into the plug-in without first calling this method.

tracks[i] = new FrameTrack(this, (PushSourceStream)streams[i], 5);

|
| public void | start()Start the parser.
source.start();
for (int i = 0; i < tracks.length; i++)
((FrameTrack)tracks[i]).start();
|
| public void | stop()Stop the parser.
try {

|
| protected boolean | supports(javax.media.protocol.SourceStream[] streams)Override this if the Parser has additional requirements
from the PushSourceStream
return ( (streams[0] != null) &&
(streams[0] instanceof PushSourceStream) );
