问题
Is there a way to run an exoplayer with both mp4 and stream m3u8 videos?
I tried but I could not find a solution.
I found the following sources for testing.
Video mp4: here
Stream m3u8: here
This is the code I wrote with the mp4 videos works, but with m3u8, no.
I made several attempts, but I did not succeed, I was thinking of using HlsMediaSource but I could not make it work.
Error, the following function is called within SimpleVideoStream.java:
public void onPlayerError(ExoPlaybackException error) {
Code:

I believe you do need to use HlsMediaSource for streaming HLS (m3u8). The following example works for me for DASH, HLS, and mp4.
// 1. Create a default TrackSelector
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new
AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new
DefaultTrackSelector(videoTrackSelectionFactory);
playerView = rootView.findViewById(R.id.videoView);
player = ExoPlayerFactory.newSimpleInstance(<context>, trackSelector);
player.setPlayWhenReady(true);
playerView.setPlayer(player);
// DASH
// DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory(
// Util.getUserAgent(<context>, "ExoPlayer"));
// DefaultDashChunkSource.Factory chunkSourceFactory = new
// DefaultDashChunkSource.Factory(dataSourceFactory);
//
// MediaSource mediaSource = new DashMediaSource(Uri.parse(<dash url>),
// dataSourceFactory, chunkSourceFactory, null, null);
// HLS
// DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(<context>,
// Util.getUserAgent(rootView.getContext(), "ExoPlayer"));
//
// // Produces Extractor instances for parsing the media data.
// ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
// Handler mainHandler = new Handler();
// MediaSource mediaSource = new HlsMediaSource(Uri.parse(
// "https://live3-mediaset-it.akamaized.net/content/hls_clr_xo/live/channel(ch09)/Stream(02)/index.m3u8"),
// dataSourceFactory, null, null);
// MP4
// Produces DataSource instances through which media data is loaded.
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(<context>,
Util.getUserAgent(rootView.getContext(), "ExoPlayer"));
// Produces Extractor instances for parsing the media data.
final ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
// This is the MediaSource representing the media to be played.
MediaSource mediaSource = new ExtractorMediaSource(Uri.parse(
"https://www.w3schools.com/html/mov_bbb.mp4"),
dataSourceFactory, extractorsFactory, null, null);
player.prepare(mediaSource);
player.setPlayWhenReady(true);
