The code

BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
                TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
                TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
                SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(getContext(), trackSelector);
                PlayerView playerView = inflate.findViewById(R.id.simple_player);
                playerView.setPlayer(player);
                RtmpDataSourceFactory rtmpDataSourceFactory = new RtmpDataSourceFactory();
                MediaSource videoSource = new ExtractorMediaSource.Factory(rtmpDataSourceFactory).createMediaSource(Uri.parse("rtmp://******* live=1"));
                player.prepare(videoSource);
                player.setPlayWhenReady(true);
