Nick,
A more appropriate place to ask these questions should be
[EMAIL PROTECTED]
Your particular problem has to do with the input RGBFormat
that needs to be converted to a format that's supported by the
QuickTime file writer. You'll need to query the processor
for the supported formats and set it on the track of the
processor. Something that looks like:
Processor p;
p.configure();
:
// Set the output content descriptor to QuickTime.
p.setContentDescriptor(new ContentDescriptor(FileTypeDescriptor.QUICKTIME));
// Query for the processor for supported formats.
// Then set it on the processor.
TrackControl tcs[] = p.getTrackControls();
Format f[] = tcs[0].getSupportedFormats();
if (f == null || f.length <= 0) {
System.err.println("The mux does not support the input format: " +
tcs[0].getFormat());
return false;
}
tcs[0].setFormat(f[0]);
p.realize();

There is also a sample solutions page for JMF on the web:
http://java.sun.com/products/java-media/jmf/2.0/solutions/
Check out the sample on:
"Generating a Movie File from a List of (JPEG) Images"
It may give you some more ideas on solving your problem.
