Demo
@Test
public void testGrabApe() throws FileNotFoundException, FrameGrabber.Exception {
// Example file is downloaded from https://example-files.online-convert.com/audio/ape/example.ape, also see attach file at the end.
FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(new FileInputStream("/path/to/example.ape"));
grabber.start();
Frame frame = grabber.grabSamples();
while (frame != null) {
System.out.println("frame.timestamp=" + frame.timestamp / 1e6);
frame = grabber.grabSamples();
}
}
Output
