Android：播放Rtsp视频流的两种方式

一.SurfaceView + Mediaplayer

XML中添加SurfaceView:

<SurfaceViewandroid:id="@+id/surface_view"android:layout_width="match_parent"android:layout_height="match_parent"/>

Activity代码：

package com.android.rtsp;import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.widget.Toast;import androidx.activity.EdgeToEdge;
import androidx.appcompat.app.AppCompatActivity;import com.android.rtsp.R;public class RtspActivity extends AppCompatActivity implements MediaPlayer.OnPreparedListener {private final String TAG = this.getClass().getSimpleName();private MediaPlayer mediaPlayer;private SurfaceView surfaceView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);EdgeToEdge.enable(this);setContentView(R.layout.activity_rtsp);surfaceView = findViewById(R.id.surface_view);SurfaceHolder holder = surfaceView.getHolder();holder.addCallback(sfvCallBack);}private SurfaceHolder.Callback sfvCallBack = new SurfaceHolder.Callback() {@Overridepublic void surfaceCreated(SurfaceHolder holder) {playVideo();}@Overridepublic void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {}@Overridepublic void surfaceDestroyed(SurfaceHolder holder) {if (mediaPlayer != null) {mediaPlayer.stop();mediaPlayer.release();mediaPlayer = null;}}};private void playVideo() {if (mediaPlayer == null) {mediaPlayer = new MediaPlayer();try {//公共Rtsp，后附多个目前可用的公共RtspmediaPlayer.setDataSource("rtsp://stream.strba.sk:1935/strba/VYHLAD_JAZERO.stream");mediaPlayer.setDisplay(surfaceView.getHolder());mediaPlayer.setOnPreparedListener(this);mediaPlayer.prepareAsync();} catch (Exception e) {e.printStackTrace();Toast.makeText(this, "Error loading video", Toast.LENGTH_SHORT).show();}}}@Overridepublic void onPrepared(MediaPlayer mp) {mediaPlayer.start();}@Overridepublic void onDestroy() {super.onDestroy();}
}

二.VideoView

源码可以看到，VideoView是SurfaceView的封装，并且实现了MediaPlayerControl的方法
所以本质还是SurfaceView+MediaPlayer

XML添加VideoView:

<VideoViewandroid:id="@+id/video_view"android:layout_width="match_parent"android:layout_height="match_parent"/>

Activity代码：

package com.android.rtsp;import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ImageButton;
import android.widget.VideoView;import androidx.activity.EdgeToEdge;
import androidx.appcompat.app.AppCompatActivity;import com.android.rtsp.R;public class RtspActivity extends AppCompatActivity {private final String TAG = this.getClass().getSimpleName();private VideoView mVideoView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);EdgeToEdge.enable(this);setContentView(R.layout.activity_rtsp);mVideoView = findViewById(R.id.video_view);}@Overridepublic void onResume() {super.onResume();if (mVideoView != null) {videoConfig();}}private void videoConfig() {//公共Rtsp，后附多个目前可用的公共RtspmVideoView.setVideoURI(Uri.parse("rtsp://stream.strba.sk:1935/strba/VYHLAD_JAZERO.stream"));//本质还是SurfaceView+MediaPlayermVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {@Overridepublic void onPrepared(MediaPlayer mp) {Log.i(TAG, "onPrepared ... ........   ");mVideoView.requestFocus();mVideoView.start();}});//简化写法/*mVideoView.setOnPreparedListener(mp -> {mVideoView.requestFocus();mVideoView.start();});*/}@Overridepublic void onDestroy() {super.onDestroy();mVideoView.suspend();}
}
