У меня на сервере есть зашифрованное видео, и я хочу воспроизвести это видео с помощью exoplayer, но не могу найти код, полностью отвечающий на мой вопрос. Я понятия не имею, как использовать customDatasource и как мне точно подключить его к exoplayer.
Я попробовал несколько примеров кода из Интернета, но это дает мне нераспознанное исключение формата.
Недавно я внедрил экзоплеер в свой проект.
Сначала создайте фрагмент или активность
class VideoViewFragment : Fragment() {
var dataSourceFac: DataSource.Factory? = null
companion object {
var nPlayer: ExoPlayer? = null
}
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
return inflater.inflate(R.layout.fragment_video_view, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
getBundledArguments()
ivCancel.setOnClickListener {
if (nPlayer != null) {
nPlayer!!.release()
nPlayer = null
}
activity?.onBackPressed()
}
}
private fun getBundledArguments() {
if (arguments != null) {
if (arguments?.getString(Constants.VIDEO_URL) != null)
playVideo(arguments?.getString(Constants.VIDEO_URL)!!)
else
activity?.onBackPressed()
}
}
private fun playVideo(videoUrl: String) {
val player: ExoPlayer
if (nPlayer != null) {
nPlayer!!.release()
nPlayer = null
}
val defaultBandwidthMeter = DefaultBandwidthMeter()
val dataSourceFactory = DefaultDataSourceFactory(activity, Util.getUserAgent(context, context!!.getString(com.app.tourguide.R.string.app_name)), defaultBandwidthMeter)
dataSourceFac = dataSourceFactory
val videoTrackSelectionFactory = AdaptiveTrackSelection.Factory(defaultBandwidthMeter)
val trackSelector = DefaultTrackSelector(videoTrackSelectionFactory)
val contentMediaSource = buildMediaSource(Uri.parse(videoUrl))
val mediaSources = arrayOfNulls<MediaSource>(2) //The Size must change depending on the Uris
mediaSources[0] = contentMediaSource //uri
val subtitleSource = SingleSampleMediaSource(Uri.parse("https://www.iandevlin.com/html5test/webvtt/upc-video-subtitles-en.vtt"),
dataSourceFactory, Format.createTextSampleFormat(null, MimeTypes.TEXT_VTT, Format.NO_VALUE, "en", null),

// mediaSources[1] = subtitleSource
