javacv写mp4_使用JavaCV和FFmpeg播放视频

首先创建CanvasFrame然后使用“canvas.showImage(captured_frame);”而不是“recorder.record(captured_frame);”

下面是代码&＃xff1a;

public class GrabberShow implements Runnable

{

final static int INTERVAL&＃61;40;///you may use interval

IplImage image;

static CanvasFrame canvas &＃61; new CanvasFrame("JavaCV player");

public GrabberShow()

{

canvas.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);

}

public static void convert(File file)

{

FFmpegFrameGrabber frameGrabber &＃61; new FFmpegFrameGrabber(file.getAbsolutePath());

IplImage captured_frame &＃61; null;

FrameRecorder recorder &＃61; null;

//recorder &＃61; new FFmpegFrameRecorder("/mnt/sdcard/external_sd/videosteste/primeiroteste.mp4", 300, 300);

recorder &＃61; new FFmpegFrameRecorder("D://temp.mp4", 300, 300);

recorder.setVideoCodec(13);

recorder.setFrameRate(30);

recorder.setFormat("mp4");

try {

recorder.start();

frameGrabber.start();

while (true) {

try {

captured_frame &＃61; frameGrabber.grab();

if (captured_frame &＃61;&＃61; null) {

System.out.println("!!! Failed cvQueryFrame");

break;

}

//recorder.record(captured_frame);

canvas.showImage(captured_frame);

Thread.sleep(INTERVAL);

} catch (Exception e) {

}

}

recorder.stop();

recorder.release();

} catch (Exception e) {

e.printStackTrace();

}

}

&＃64;Override

public void run()

{

convert(new File("D://aes.mp4"));

}

public static void main(String[] args) {

GrabberShow gs &＃61; new GrabberShow();

Thread th &＃61; new Thread(gs);

th.start();

}

}
