ExoPlayer 2.18.4 无法播放某些视频和音频

Question

我想更新 playstore 中的一个旧应用程序（将近 3 年）。除了这个 ExoPlayer 库之外，我已经修复了不推荐使用的代码和库。我遵循了这个tutorial并且它没有问题。但是当我使用我的实际 mp3/mp4 文件时，我遇到了一个对我来说是新的错误。我已经在互联网上搜索过这个问题，但没有运气。

这是我的代码

   private lateinit var binding: PlayerActivityBinding
    private var exoPlayer: ExoPlayer? = null
    private var playbackPosition = 0L
    private var playWhenReady = true

// some override ...

  private fun preparePlayer() {
        exoPlayer = ExoPlayer.Builder(this).build()
        exoPlayer?.playWhenReady = true
        binding.playerView.player = exoPlayer
        val defaultHttpDataSourceFactory = DefaultHttpDataSource.Factory()
        val mediaItem = MediaItem.fromUri(URL)
        val mediaSource =
            DashMediaSource.Factory(defaultHttpDataSourceFactory).createMediaSource(mediaItem)
        exoPlayer?.setMediaSource(mediaSource)
        exoPlayer?.seekTo(playbackPosition)
        exoPlayer?.playWhenReady = playWhenReady
        exoPlayer?.prepare()
    }

    private fun  releasePlayer(){
        exoPlayer?.let { player ->
            playbackPosition = player.currentPosition
            playWhenReady = player.playWhenReady
            player.release()
            exoPlayer = null
        }
    }

companion object{
        const val URL =
            "https://bitmovin-a.akamaihd.net/content/MI201109210084_1/mpds/f08e80da-bf1d-4e3d-8899-f0f6155f6efa.mpd"
    }

    implementation 'com.google.android.exoplayer:exoplayer:2.18.4'
    implementation 'androidx.media3:media3-exoplayer-ima:1.0.0'
    implementation 'com.google.android.exoplayer:extension-ima:2.18.4'

请注意，旧版本的 exoplayer 正在处理我实际的 mp3 文件。但在这个最新版本中，它不会。
