Have a problem getting Exoplayer to work. I managed to load the video from a url. But it only plays the audio. So i am doing something wrong.
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveVideoTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
LoadControl loadControl = new DefaultLoadControl();
SimpleExoPlayer exoPlayer = ExoPlayerFactory.newSimpleInstance(simpleExoPlayerView.getContext(), trackSelector, loadControl);
Uri mp4VideoUri = Uri.parse(videoUri);
DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory("ExoPlayerDemo");
ExtractorsFactory extractor = new DefaultExtractorsFactory();
MediaSource videoSource = new ExtractorMediaSource(mp4VideoUri, dataSourceFactory, extractor, null, null);
exoPlayer.prepare(videoSource);
exoPlayer.setPlayWhenReady(true);
This is how i where able to only play the audio. Not sure what i should change.
Looks like you miss to bind player to player view
Attaching player to view
The ExoPlayer library provides a SimpleExoPlayerView, which encapsulates a PlaybackControlView and a Surface onto which video is rendered. A SimpleExoPlayerView can be included in your application’s layout xml. Binding the player to the view is as simple as:
// Bind the player to the view.
simpleExoPlayerView.setPlayer(player);
If you require fine-grained control over the player controls and the Surface onto which video is rendered, you can set the player’s target SurfaceView, TextureView, SurfaceHolder or Surface directly using SimpleExoPlayer’s setVideoSurfaceView, setVideoTextureView, setVideoSurfaceHolder and setVideoSurface methods respectively. You can use PlaybackControlView as a standalone component, or implement your own playback controls that interact directly with the player. setTextOutput and setId3Output can be used to receive caption and ID3 metadata output during playback.

Hi I am creating an app that will broadcast live and another user can view it
I am currently using flash to push it into WOWZA and I am using exoplayer for viewing it
I am using RTMP because it's the only one supported by exoplayer which has low latency
everything works perfect however when I mute the microphone in the live side the video in exoplayer will freeze and will go to status
STATE_BUFFERING but it will not proceed to STATE_READY
and if I unmute it will go back to normal and can view it again from
STATE_BUFFERING to STATE_READY
And anyway I tried the stream to view in VLC and it does work it doesn't freeze
I tried other solution but doesn't work
my code is this
//initiate Player
//Create a default TrackSelector
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
//Create the player
SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);
PlayerView playerView = findViewById(R.id.simple_player);
playerView.setPlayer(player);
RtmpDataSourceFactory rtmpDataSourceFactory = new RtmpDataSourceFactory();
// This is the MediaSource representing the media to be played.
MediaSource videoSource = new ExtractorMediaSource.Factory(rtmpDataSourceFactory)
.createMediaSource(Uri.parse(URL));
player.prepare(videoSource);
//auto start playing
player.setPlayWhenReady(true);
I hope someone helps me!!!
thank you in advance
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 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 have integrated android exoplayer in my application. I have to detect the HLS (.m3u8) stream received is for Live or VOD or Event, so depending on that controller has to be modified for the player. I have only one instance of player so that should handle all the supported media like vod or live or event.
I am looking for some debug points to know working of m3u8 parser in exoplayer so that I can able to receive this parameters.
You can use below code to play .m3u8 file:-
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
//Create the player using ExoPlayerFactory
videoPlayer = ExoPlayerFactory.newSimpleInstance(context,trackSelector);
Handler mHandler = new Handler();
String userAgent = Util.getUserAgent(context, "Exo Player");
DataSource.Factory dataSourceFactory = new DefaultHttpDataSourceFactory(
userAgent, null,
DefaultHttpDataSource.DEFAULT_CONNECT_TIMEOUT_MILLIS,
1800000,
true);
HlsMediaSource mediaSource = new HlsMediaSource(Uri.parse(mediaUrl),dataSourceFactory, 1800000,mHandler, null);
if (mediaUrl != null) {
videoPlayer.prepare(mediaSource);
videoPlayer.setPlayWhenReady(true);
}
Live vs Event differentiation is not supported, yet. For Live vs Event you can check the current Timeline, but that's not HLS specific. For distinguish a live stream from a vod one by querying the player's duration after it is prepared. Live streams will return UNKNOWN_TIME, where-as vod streams will return the known duration of the stream.
I am currently looking to develop an application that utilises Dash through the ExoPlayer in Android.
To begin with I am going through the demo project however am having trouble with even creating a simple working instance of ExoPlayer that can stream mp3 or similar.
Would really appreciate any help anyone can give relating to getting a very simple exoplayer instance working from which i can adapt and build upon or if anyone has any leads for more references or guides which I can follow as there seems to be very little documentation available.
Thanks very much for all and any help!
First of all instantiate your ExoPlayer with this line:
exoPlayer = ExoPlayer.Factory.newInstance(RENDERER_COUNT, minBufferMs, minRebufferMs);
If you want to play audio only you can use these values:
RENDERER_COUNT = 1 //since you want to render simple audio
minBufferMs = 1000
minRebufferMs = 5000
Both buffer values can be tweaked according to your requirements
Now you have to create a DataSource. When you want to stream mp3 you can use the DefaultUriDataSource. You have to pass the Context and a UserAgent. To keep it simple play a local file and pass null as userAgent:
DataSource dataSource = new DefaultUriDataSource(context, null);
Then create the sampleSource:
ExtractorSampleSource sampleSource = new ExtractorSampleSource(
uri, dataSource, new Mp3Extractor(), RENDERER_COUNT, requestedBufferSize);
uri points to your file, as an Extractor you can use a simple default Mp3Extractor if you want to play mp3. requestedBufferSize can be tweaked again according to your requirements. Use 5000 for example.
Now you can create your audio track renderer using the sample source as follows:
MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(sampleSource);
Finally call prepare on your exoPlayer instance:
exoPlayer.prepare(audioRenderer);
To start playback call:
exoPlayer.setPlayWhenReady(true);
Here is how you would do it using the new ExoPlayer 2 API, and the SimpleExoPlayer.
First create the player:
DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(context, bandwidthMeter);
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
DefaultTrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
LoadControl loadControl = new DefaultLoadControl();
SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(context, trackSelector, loadControl);
player.addListener(...); // To receive events from the player
Then create your MediaSource. For MP3 you can use ExtractorMediaSource:
ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
Uri uri = Uri.parse(mp3UriString);
Handler mainHandler = new Handler(Looper.getMainLooper());
MediaSource mediaSource = new ExtractorMediaSource(uri, dataSourceFactory, extractorsFactory, mainHandler, mediaSourceListener); // Listener defined elsewhere
Then prepare and play when ready:
player.prepare(mediaSource);
player.setPlayWhenReady(true);
For DASH you would use DashMediaSource instead of ExtractorMediaSource.
Today while working on a project, I found that this.myExoPlayer = ExoPlayerFactory.newSimpleInstance(getActivity()); and some others are now deprecated and Android studio suggested to use new way. So I did a quick Google for it but everywhere I found the old way. So I looked into the SimpleExoPlayer.java file, read some methods. So this is how you initialize simpleExoPlayer:
Activity activity = getActivity(); // if you are in a fragment
// Or, activity = YourActivity.this; if you are in an Activity
SimpleExoPlayer simpleExoPlayer = new SimpleExoPlayer.Builder(activity).build();
I hope this is helpful.
