问题 I have a class, which watching rtmp stream with help of ExoPLayer: player = ExoPlayerFactory.newSimpleInstance(context) val rtmpDataSourceFactory = RtmpDataSourceFactory() val videoSource = ProgressiveMediaSource.Factory(rtmpDataSourceFactory) .createMediaSource(Uri.parse(streamURL)) player.prepare(videoSource) player.setVideoTextureView(playerView) player.playWhenReady = true playerView is TextureView, picked instead of SurfaceView, because i also need to take screenshots from stream. As far
