Android：播放Rtsp视频流的两种方式

一.SurfaceView + Mediaplayer

XML中添加SurfaceView:

<SurfaceView
    android: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;

    @Override
    protected 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() {
        @Override
        public void surfaceCreated(SurfaceHolder holder) {
            playVideo();
        }

        @Override
        public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
        }

        @Override
        public 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Rtsp
                mediaPlayer.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();
            }
        }
    }

    @Override
    public void onPrepared(MediaPlayer mp) {
        mediaPlayer.start();
    }

    @Override
    public 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:

<VideoView
    android: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;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);
        setContentView(R.layout.activity_rtsp);

        mVideoView = findViewById(R.id.video_view);
    }

    @Override
    public 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Rtsp
        mVideoView.setVideoURI(Uri.parse("rtsp://stream.strba.sk:1935/strba/VYHLAD_JAZERO.stream"));

        //本质还是SurfaceView+MediaPlayer
        mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {
                Log.i(TAG, "onPrepared ... ........   ");
                mVideoView.requestFocus();
                mVideoView.start();
            }
        });

        //简化写法
        /*mVideoView.setOnPreparedListener(mp -> {
            mVideoView.requestFocus();
            mVideoView.start();
        });*/

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mVideoView.suspend();
    }
}
