Android 尝试使用ExoPlayer播放RTMP流

我有以下代码：

SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(this);
    PlayerView playerView = findViewById(R.id.simple_player);
    playerView.setPlayer(player);

    RtmpDataSourceFactory rtmpDataSourceFactory = new RtmpDataSourceFactory();
 MediaSource videoSource = new ProgressiveMediaSource.Factory(rtmpDataSourceFactory)
            .createMediaSource(Uri.parse("https://player.cdnmedia.tv/embed/a77aa67c"));
player.prepare(videoSource);
player.setPlayWhenReady(true);

这是我的渐变文件：

apply plugin: 'com.android.application'

android {
compileSdkVersion 28
defaultConfig {
    applicationId "my.company.streaming"
    minSdkVersion 26
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])

testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

我的stacktrace崩溃了：

AbstractMethodError

AbstractMethod“void com.google.android.exoplayer2.upstream.DataSource.addTransferListener（com.google.android.exoplayer2.upstream.TransferListener）

意味着您必须实现抽象方法/

.addTransferListener（TransferListener）

.Class将已经实现了

接口

（这可以是任何其他实现该接口的类）

请尝试另一个构造函数：

BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);

我已经这样做了，现在我收到了“源错误”“。流媒体当前未联机，这可能是原因吗？如果我将URL粘贴到浏览器中，我会看到彩色条，而我在应用程序中看不到。我正在等待客户端启动一个测试流，看看它是否工作，如果有一些内容实际上是流的。将使用结果进行更新，如果有效，将接受答案。谢谢你的帮助。尝试在邮递员返回“无法得到任何回应”。在Postman的设置中不允许SSL认证看起来我得到了一些东西（html代码）。客户端开始流式处理，我收到了源错误。更新我的问题。

BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);
