Get Frame Rate and Resolution from a video file

[Chia-you Chai]

Hello, I want to get the frame rate, fps and resolution from a video file store in the local disk. Does any java api or library can help me to get such information ? Thanks a lot

Perhaps the Java Media Framework (JMF) can help you out.

Finally JMF helps a lot. You can call the getFormat method by specify a locator instance.

 	public Format getFormat(MediaLocator locator) throws NoProcessorException, IOException {
		final Processor processor = Manager.createProcessor(locator);
		processor.configure();
		final List fmts = new ArrayList();
		processor.addControllerListener(new ControllerListener() {
		    @Override
			public void controllerUpdate(ControllerEvent evt) {
				if (evt instanceof ConfigureCompleteEvent) {
					for (TrackControl o : processor.getTrackControls()) {
						fmts.add(o.getFormat());
					}
					if (fmts.isEmpty()) {
						fmts.add(null);
					}
					processor.close();
				}
			}
		});

		while (fmts.isEmpty()) {
			try {
				Thread.sleep(100);
			} catch(InterruptedException ignored) {}
		}
		format = (Format) fmts.get(0);
		return format;
    }
