i have little problem with exoplayer. almost everything works fine when i try to play video from hls stream. hls stream contains 3 different sets of chunklists each for different bandwidth.
but hls adaptive streaming is not working and player works only with one chunklist and with slow internet connection is this solution unusable.
source code:
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
this.simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(getActivity(), trackSelector);
this.videoPlayer.setPlayer(this.simpleExoPlayer);
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this.getActivity(), Util.getUserAgent(this.getActivity(), "appName"));
MediaSource mediaSource = new HlsMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(hlsUrl));
this.simpleExoPlayer.prepare(mediaSource);
this.simpleExoPlayer.setPlayWhenReady(true);
i tried to implement MediaSourceEventListener too and onDownstreamFormatChanged is called only once in the moment of player initialization.
thanks for any advices
The key here is you need to pass the same "bandwidthMeter" you passed in to AdaptiveTrackSelection.Factory to the dataSourceFactory too.
Only after these changes the Exoplayer does adaptive streaming as expected.
String userAgent = "XYZPLAYER";
DefaultHttpDataSourceFactory httpDataSourceFactory = new DefaultHttpDataSourceFactory(userAgent, bandwidthMeter, DefaultHttpDataSource.DEFAULT_CONNECT_TIMEOUT_MILLIS, DefaultHttpDataSource.DEFAULT_READ_TIMEOUT_MILLIS, true);
DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(this, bandwidthMeter, httpDataSourceFactory);

I am playing video on Android using ExoPlayer. But " DefaultBandwidthMeter();" is deprecated.
DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
//DefaultTrackSelector chooses tracks in the media item
DefaultTrackSelector trackSelector = new DefaultTrackSelector(this);
trackSelector.setParameters(trackSelector.buildUponParameters().setMaxVideoSizeSd());
mPlayer = new SimpleExoPlayer.Builder(this).setTrackSelector(trackSelector).build();
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "exoplayerapp"), bandwidthMeter);
MediaSource mediaSource = new ProgressiveMediaSource.Factory(dataSourceFactory).createMediaSource(Uri.parse(url));
mPlayer.prepare(mediaSource);
playerView.setKeepScreenOn(true);
playerView.requestFocus();
playerView.setPlayer(mPlayer);
mPlayer.setPlayWhenReady(true);
playBackStateListener = new PlayBackStateListener();
mPlayer.addListener(playBackStateListener);
What should I use insead of this and according to that with what I should replace the following line which is using theis bandwidthMeter?
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "exoplayerapp"), bandwidthMeter);
You should use DefaultBandwidthMeter.Builder. Source from ExoPlayer documentation.
If you use HLS Media Type you should this:
val defaultHttpDataSourceFactory = DefaultHttpDataSource.Factory()
Note: It worked this version: implementation 'com.google.android.exoplayer:exoplayer:2.18.2'
I'm using Exoplayer version 2 for playing Video from Internal Storage and it works fine but whenever video contains ac3 type audio,exoplayer not plays audio,it only display video.
please help me
DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);
dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "exoplayer2example"), bandwidthMeter);
ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory().setConstantBitrateSeekingEnabled(true);
videoSource = new ExtractorMediaSource(uri, dataSourceFactory, extractorsFactory, null, null);
player.prepare(videoSource);
Same Problem also Occurring with Android Media player
I want to play encrypted videos using ExoPlayer I am very new to ExoPlayer I don't know much about that. I found some links[https://stackoverflow.com/a/54247524/9789670] but those are not working fine.I need some help regrading this issue
Use this code for play video
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(null);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(mContxt, trackSelector);
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(mContxt,
Util.getUserAgent(mContxt, "CloudExoplayer"));
Uri videoUri = Uri.parse(url);
MediaSource videoSource = new ExtractorMediaSource.Factory(dataSourceFactory)
.createMediaSource(videoUri);
player.prepare(videoSource);
player.setRepeatMode(Player.REPEAT_MODE_ALL);
exoplayer.setPlayer(player);
exoplayer.requestFocus();
exoplayer.setPlayWhenReady(true);
I am using Exoplayer in my application and I want to show DashMediaSource.
I did it and the video will play this Code:
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, "ExoPlayer"));
Uri uri = Uri.parse(videoUrl);
DashMediaSource dashMediaSource = new DashMediaSource(uri, dataSourceFactory,
new DefaultDashChunkSource.Factory(dataSourceFactory), null, null);
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelector trackSelector = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory(bandwidthMeter));
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);
simpleExoPlayerView.setPlayer(player);
player.prepare(dashMediaSource);
But I need to show the user a selector for the quality of this vide0.
I just want to get all available qualities from my dash file and show it to the use.
In ExoPlayer 1.5.8, I used getTrackCount() to get all available qualities but in ExoPlayer 2.5.3 it is not available anymore.
How can I do that?
I really appreciate your help.
Have you tried using AnalyticsListener?
player.addAnalyticsListener(new AnalyticsListener() {
#Override
public void onBandwidthEstimate(EventTime eventTime, int totalLoadTimeMs, long totalBytesLoaded, long bitrateEstimate) {
}
});
I'm new on ExoPlayer , i'm currently heading to use it to play Native Udp Stream ( From french digital Television : 1080p 5-10 mbps in Variable bitrate )
I manage to play some udp stream with some tests videos from http://jell.yfish.us/ on different devices .
I have make some different video decoding test with HLS and Udp Streaming with this code for UDP :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.myactivity);
sufaceview = (SurfaceView) findViewById(R.id.surfaceView2);
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory =
new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector =
new DefaultTrackSelector(videoTrackSelectionFactory);
LoadControl loadControl = new DefaultLoadControl(
new DefaultAllocator(true, C.DEFAULT_BUFFER_SEGMENT_SIZE),
15000, 60000, 2500, 6000);
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl);
Uri uri =
Uri.parse
("udp://#239.192.2.2:1234");
final DefaultBandwidthMeter bandwidthMeterA = new DefaultBandwidthMeter();
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this,
Util.getUserAgent(this, "teveolauncher"), bandwidthMeterA);
extractorsFactory = new DefaultExtractorsFactory();
DataSource.Factory udsf = new UdpDataSource.Factory() {
#Override
public DataSource createDataSource() {
return new UdpDataSource(null, 3000, 100000);
}
};
ExtractorsFactory tsExtractorFactory = new ExtractorsFactory() {
#Override
public Extractor[] createExtractors() {
return new TsExtractor[]{new TsExtractor(MODE_SINGLE_PMT,
new TimestampAdjuster(0), new DefaultTsPayloadReaderFactory())};
}
};
MediaSource videoSource = new ExtractorMediaSource
(uri, udsf, tsExtractorFactory, null, null);
player.setVideoSurfaceView(sufaceview);
player.prepare(videoSource);
player.setPlayWhenReady(true);
}
For HLS I just Change the MediaSource and the datasourceFactory :
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this,
Util.getUserAgent(this, "teveolauncher"), bandwidthMeterA);
MediaSource videoSource = new HlsMediaSource
(uri, dataSourceFactory, null, null);
I Know Udpstreaming is not officialy supported by ExoPlayer but the UdpDataSource class seems to work well.
After all the test , i noticed video with a variable biterate like french DTT can't be decoded correctly but with Constatnt biterate video like Jell yfish the decoding process is perfect .
There is some coding improvement to make VBR video decoded correctly ?
Thank you by advance :)
Sorry for my bad english :)
Uri uri = Uri.parse("udp://#239.192.2.2:1234");
I think UDP is not a protocol - it's a transport, (like TCP). You can't use a tcp://host:port/ URL either.
Or does it work?
