无法使用HLS流运行FFmpegFrameGrabber

如何解决无法使用HLS流运行FFmpegFrameGrabber

我需要使用FFmpegFrameGrabber将实时流http livestreaming转换为10秒的图像和音频片段。我总是在下面的代码中获取grabpedimage null。我需要使用javacv下载实时流的帮助。

URL streamUrl = new URL("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4");

URLConnection connection = streamUrl.openConnection();

InputStream is2 = connection.getInputStream();
FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(is2);
Frame grabbedImage = null;
grabber.start();
grabber.setFrameRate(grabber.getFrameRate());

Java2DFrameConverter c = new Java2DFrameConverter();
while ((grabbedImage = grabber.grab()) != null) {
    ImageIO.write(c.convert(grabbedImage),"png",new File("/mnt/test/" + System.currentTimeMillis() + ".png"));
}
grabber.close();
