Android 播放Rtmp流 的3种不同方式的demo

好的，以下是三种不同方式的 Android 播放 Rtmp 流的 demo：

1. 使用 Vitamio

Vitamio 是一个支持多种视频格式的 Android 播放器，它也支持播放 RTMP 流。使用 Vitamio 播放 RTMP 流需要先下载 Vitamio SDK，并在项目中引用。

示例代码：

import io.vov.vitamio.MediaPlayer;
import io.vov.vitamio.Vitamio;
import io.vov.vitamio.widget.VideoView;

public class MainActivity extends AppCompatActivity implements MediaPlayer.OnInfoListener, MediaPlayer.OnBufferingUpdateListener {

    private VideoView videoView;
    private String rtmpUrl = "rtmp://your.rtmp.url";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Vitamio.isInitialized(getApplicationContext());
        setContentView(R.layout.activity_main);

        videoView = findViewById(R.id.video_view);
        videoView.setVideoPath(rtmpUrl);
        videoView.setOnInfoListener(this);
        videoView.setOnBufferingUpdateListener(this);
        videoView.start();
    }

    @Override
    public boolean onInfo(MediaPlayer mp, int what, int extra) {
        switch (what) {
            case MediaPlayer.MEDIA_INFO_BUFFERING_START:
                // Show loading spinner
                break;
            case MediaPlayer.MEDIA_INFO_BUFFERING_END:
                // Hide loading spinner
                break;
        }
        return true;
    }

    @Override
    public void onBufferingUpdate(MediaPlayer mp, int percent) {
        // Update loading spinner progress
    }
}

2. 使用 ExoPlayer

ExoPlayer 是 Google 推出的一个支持多种格式的 Android 播放器，它也支持播放 RTMP 流。使用 ExoPlayer 播放 RTMP 流需要先下载 ExoPlayer SDK，并在项目中引用。

示例代码：

import com.google.android.exoplayer2.ExoPlayer;
import com.google.android.exoplayer2.ExoPlayerFactory;
import com.google.android.exoplayer2.PlaybackParameters;
import com.google.android.exoplayer2.SimpleExoPlayer;
import com.google.android.exoplayer2.source.ExtractorMediaSource;
import com.google.android.exoplayer2.source.MediaSource;
import com.google.android.exoplayer2.source.ProgressiveMediaSource;
import com.google.android.exoplayer2.trackselection.DefaultTrackSelector;
import com.google.android.exoplayer2.trackselection.TrackSelector;
import com.google.android.exoplayer2.ui.PlayerView;
import com.google.android.exoplayer2.upstream.DataSource;
import com.google.android.exoplayer2.upstream.DefaultDataSourceFactory;
import com.google.android.exoplayer2.upstream.DefaultHttpDataSourceFactory;
import com.google.android.exoplayer2.upstream.DefaultRawResourceDataSourceFactory;
import com.google.android.exoplayer2.upstream.DataSource.Factory;
import com.google.android.exoplayer2.util.Util;

public class MainActivity extends AppCompatActivity {

    private PlayerView playerView;
    private String rtmpUrl = "rtmp://your.rtmp.url";
    private SimpleExoPlayer player;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        playerView = findViewById(R.id.player_view);
        player = ExoPlayerFactory.newSimpleInstance(this, new DefaultTrackSelector());

        DataSource.Factory dataSourceFactory = new DefaultHttpDataSourceFactory(Util.getUserAgent(this, "your-application-name"));
        MediaSource videoSource = new ExtractorMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(rtmpUrl));
        player.prepare(videoSource);
        player.setPlayWhenReady(true);

        playerView.setPlayer(player);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        player.release();
    }
}

3. 使用 ffmpeg

ffmpeg 是一个开源的音视频处理库，它也支持播放 RTMP 流。使用 ffmpeg 播放 RTMP 流需要先下载 ffmpeg 库，并在项目中引用。

示例代码：

import android.os.Bundle;
import android.os.Handler;
import android.os.Looper;
import android.view.SurfaceView;
import android.view.View;
import android.widget.Button;

import androidx.appcompat.app.AppCompatActivity;

import com.arthenica.mobileffmpeg.Config;
import com.arthenica.mobileffmpeg.ExecuteCallback;
import com.arthenica.mobileffmpeg.ExecuteException;
import com.arthenica.mobileffmpeg.FFmpeg;
import com.arthenica.mobileffmpeg.FFprobe;

public class MainActivity extends AppCompatActivity {

    private SurfaceView surfaceView;
    private String rtmpUrl = "rtmp://your.rtmp.url";
    private String[] cmd = {"-rtmp_live", "live", "-i", rtmpUrl, "-c:v", "copy", "-c:a", "aac", "-strict", "-2", "-f", "flv", "-"};
    private boolean isPlaying = false;
    private Handler handler = new Handler(Looper.getMainLooper());

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        surfaceView = findViewById(R.id.surface_view);
        Button playButton = findViewById(R.id.play_button);
        playButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (isPlaying) {
                    stopPlaying();
                    playButton.setText("Play");
                } else {
                    startPlaying();
                    playButton.setText("Stop");
                }
            }
        });
    }

    private void startPlaying() {
        Config.enableStatisticsCallback(new ExecuteCallback() {
            @Override
            public void apply(long executionId, int returnCode) {
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        // Update statistics
                    }
                });
            }
        });

        FFmpeg.executeAsync(cmd, new ExecuteCallback() {
            @Override
            public void apply(long executionId, int returnCode) {
                isPlaying = false;
            }
        });
        isPlaying = true;
    }

    private void stopPlaying() {
        FFmpeg.cancel();
        isPlaying = false;
    }
}
