6. Which library to use?
7. Media3 media3-exoplayer media3-ui media3-session media3-common androidx.media3 exoplayer-dash media3- exoplayer-dash
8. Media3 • tools for transcoding and video editing with media3-transformer • easy to migrate from ExoPlayer • Jetpack will be the home for ExoPlayer future releases
9. Media3 Adding dependency def media3_version = "1.0.0-alpha03" implementation "androidx.media3:media3-exoplayer:$media3_version" implementation "androidx.media3:media3-ui:$media3_version" implementation "androidx.media3:media3-exoplayer-dash:$media3_version"
10. Media3 Setup playback val player = ExoPlayer.Builder(requireContext()).build() binding.playerView.player = player val mediaItem = MediaItem.fromUri("url_here") player.setMediaItem(mediaItem) player.playWhenReady = true player.prepare()

14. Media Session • a universal way of interacting with a video/audio player • playback control can be delegated to external sources
 (buttons from remote controls, voice commands from Google Assistant)
15. Media Session Setup val session = MediaSession.Builder(requireContext(), player).build() // session is ready to use now, eg. session.connectedControllers def media3_version = "1.0.0-alpha03" implementation "androidx.media3:media3-session:$media3_version"
