Video 录像？

我正在尝试制作一个记录视频并将文件存储在表视图中的应用程序。我希望能够看到每个单元格上的预览，当我按下单元格时，先前录制并存储在此处的视频开始播放。最好的方法是什么？如果有教程或视频教程，有人可以将我重定向到那里吗？

以下是录制视频的代码：

package milos.stackVideo;

import java.io.FileOutputStream;
import java.io.IOException;

public class EnregistrementVideoStackActivity extends Activity implements Callback {
private SurfaceHolder surfaceHolder;
private SurfaceView surfaceView;
public MediaRecorder mrec = new MediaRecorder();
private Button startRecording = null;
//private Button stopRecording = null;
File video;
private Camera mCamera;


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.camera_surface);
    Log.i(null , "Video starting");
    startRecording = (Button)findViewById(R.id.buttonstart);
    mCamera = Camera.open();
    surfaceView = (SurfaceView) findViewById(R.id.surface_camera);
    surfaceHolder = surfaceView.getHolder();
    surfaceHolder.addCallback(this);
    surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}




@Override
public boolean onCreateOptionsMenu(Menu menu)
{
menu.add(0, 0, 0, "StartRecording");
menu.add(0, 1, 0, "StopRecording");
return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case 0:
try {

startRecording();

} catch (Exception e) {
String message = e.getMessage();
Log.i(null, "Problem Start"+message);
mrec.release();
}
break;

case 1: //GoToAllNotes
mrec.stop();
mrec.release();
mrec = null;
break;

}
return super.onOptionsItemSelected(item);
}



protected void startRecording() throws IOException 
{


    mrec = new MediaRecorder();  // Works well
    mCamera.unlock();

    mrec.setCamera(mCamera);

    mrec.setPreviewDisplay(surfaceHolder.getSurface());
    mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mrec.setAudioSource(MediaRecorder.AudioSource.MIC); 

    mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
    mrec.setPreviewDisplay(surfaceHolder.getSurface());
    mrec.setOutputFile("/sdcard/zzzz.3gp"); 

    mrec.prepare();
    mrec.start();

}

protected void stopRecording() {
    mrec.stop();
    mrec.release();
    mCamera.release();
  }

private void releaseMediaRecorder(){
    if (mrec != null) {
        mrec.reset();   // clear recorder configuration
        mrec.release(); // release the recorder object
        mrec = null;
        mCamera.lock();           // lock camera for later use
    }
}

private void releaseCamera(){
    if (mCamera != null){
        mCamera.release();        // release the camera for other applications
        mCamera = null;
    }
}


@Override

        int height) {

    // TODO Auto-generated method stub

}


@Override
public void surfaceCreated(SurfaceHolder holder) {
    // TODO Auto-generated method stub

    if (mCamera != null){
        Parameters params = mCamera.getParameters();
        mCamera.setParameters(params);
    }
    else {
        Toast.makeText(getApplicationContext(), "Camera not available!", Toast.LENGTH_LONG).show();
        finish();
    }

}


@Override
public void surfaceDestroyed(SurfaceHolder holder) {
    mCamera.stopPreview();
    mCamera.release();
    // TODO Auto-generated method stub

}

它可能对某些人有用。

为了缩小可能性的范围，你想写一个这样做的程序吗？如果是这样，您最熟悉哪种编程语言？您是否想要一个控件，可以在您的程序中完成大多数复杂的视频工作。或者你想要一个预构建的完整的软件应用程序来实现这一点并且易于使用？你的视频文件是什么格式？如果你的其他问题都是关于iPhone的，我想这就是你要问的平台。
