当我尝试将 HLS 视频从我的应用程序投射到 chromecast 时发生崩溃。我使用 ExoPlayer cast 扩展。

我正在使用 exoplayer 版本2.11.1和播放服务演员框架版本18.0.0。该代码是从动态模块中调用的(apply plugin: 'com.android.dynamic-feature'在模块中build.gradle)。这是我的实现:

当我们创建 Fragment 时:

private fun initCast() {
    mediaRouteButton = view?.findViewById(R.id.media_route_button)

    CastButtonFactory.setUpMediaRouteButton(activity?.applicationContext, mediaRouteButton)
    val castContext = CastContext.getSharedInstance()

    castContext?.addCastStateListener { state ->
        if (isAdded) {
            if (state == CastState.NO_DEVICES_AVAILABLE) {
                isCastAvailable = false
            } else {
                isCastAvailable = true
                mediaRouteButton?.visibility = videoTitle.visibility
            }
        }
    }
}

当用户单击 Cast 按钮时:

private fun prepareCast(title: String) {
    CastContext.getSharedInstance()?.let {
        castPlayer = CastPlayer(it)
    }

    val movieMetadata = MediaMetadata(MediaMetadata.MEDIA_TYPE_MOVIE)
    movieMetadata.putString(MediaMetadata.KEY_TITLE, title)
    videoThumbnail?.let {
        movieMetadata.addImage(WebImage(Uri.parse(it)))
    }
    val mediaInfo = MediaInfo.Builder(videoUrl)
        .setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
        .setContentType(MimeTypes.VIDEO_UNKNOWN)
        .setMetadata(movieMetadata).build()

    val mediaItems = arrayOf(MediaQueueItem.Builder(mediaInfo).build())

    castPlayer?.setSessionAvailabilityListener(object : SessionAvailabilityListener {
        override fun onCastSessionAvailable() {
            castPlayer?.loadItems(mediaItems, 0, playerViewModel.getVideoPosition(), Player.REPEAT_MODE_OFF)
            playerViewModel.pauseVideo()
        }

        override fun onCastSessionUnavailable() {
            castPlayer?.currentPosition?.let {
                playerViewModel.setVideoPosition(it)
                playerViewModel.playVideo()
            }
        }
    })
}

当用户单击我的应用程序中的投射按钮,然后在对话框中他们想要投射的设备上单击时,应用程序会系统地崩溃。这是堆栈跟踪

该应用程序在 Pixel 3 和 Pixel 3a 上崩溃,但在三星 S9 上不会崩溃。

有人可以告诉我我错过了什么吗?

经过一周的调查,发现了两个 Github 问题(在GlideExoPlayer上)我仍然没有找到任何解决方案。所以我最终将播放服务演员框架版本从18.0.0. 17.0.0至少我的应用程序停止崩溃并且它的行为符合我的要求。

我希望找到更好的解决方案。
