Android录制视频MediaRecorder+SurfaceView的使用方法，供大家参考，具体内容如下
先看效果图：
<1>将视频动画显示到SurfaceView控件上
<2>使用MediaRecorder类进行视频的录制
常用的方法：
mediaRecorder.reset(); mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); //从照相机采集视频 mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); mediaRecorder.setVideoFrameRate(3); //每秒3帧 mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263); //设置视频编码方式 mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); File videoFile = new File(Environment.getExternalStorageDirectory(), System.currentTimeMillis()+".3gp"); mediaRecorder.setOutputFile(videoFile.getAbsolutePath()); mediaRecorder.setPreviewDisplay(surfaceView.getHolder().getSurface()); mediaRecorder.prepare();//预期准备 mediaRecorder.start();//开始刻录 mediaRecorder.stop();//停止刻录
下面看代码：
public class MediaRecorderActivity extends AppCompatActivity {
private SurfaceView sv_mediarecorder_surface;
private MediaRecorder mediaRecorder;
private boolean isStartAndStop=false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
setContentView(R.layout.activity_mediarecorder);
//获取SurfaceView
sv_mediarecorder_surface = (SurfaceView) findViewById(R.id.sv_mediarecorder_surface);
//实例化媒体录制器
mediaRecorder = new MediaRecorder();
}
//视频录制与暂停的方法
public void startMediaCorder(View view){
Button button= (Button) view;
if (!isStartAndStop) {
if (mediaRecorder==null){
//实例化媒体录制器
mediaRecorder = new MediaRecorder();
}
mediaRecorder.reset();
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); //从照相机采集视频
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);//设置麦克风
//设置保存的格式
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
//设置编码格式
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mediaRecorder.setVideoFrameRate(3);
//获取根路径
String sdPath= Environment.getExternalStorageDirectory().getAbsolutePath();
//设置保存的路径
mediaRecorder.setOutputFile(sdPath+"/taoge"+System.currentTimeMillis()+".mp4");
//将画面展示到SurfaceView
mediaRecorder.setPreviewDisplay(sv_mediarecorder_surface.getHolder().getSurface());
//准备
try {
mediaRecorder.prepare();
mediaRecorder.start();
} catch (IOException e) {
e.printStackTrace();
}
button.setText("结束");
}else{
// 为其它应用释放摄像头
mediaRecorder.release();
mediaRecorder = null;
//关闭
button.setText("开始");
}
isStartAndStop=!isStartAndStop;
}
}
