Detect when LIVE event is ended

[zishanj]

I am using HlsMediaSource class to render Live events. At the backend I am using Flash Media Live Encoder. Initially when the user click the play button and event is not started, the Flash Media Live Encoder would remove the url due to which ExoPlayer will get 404 message which I can trace easily in onPlayerError listener.

The problem is, once the event is started and later it get ended, is there any specific event that will trigger to notify that the event has ended?

Have you tried ExoPlayer.EventListener.onPlayerStateChanged(). You can look at the demo app for a usage example.

[zishanj]

Yes, its STATE_ENDED only triggered when pre-recorded source is played, for Live content its never triggered.

Perhaps the server is not correctly adding the #EXT-X-ENDLIST tag to the media playlists when the stream ends. In this case the server is technically indicating that it could still add segments, and the player will therefore wait in the buffering state.

Thanks, this explains it well.

This should be easy to check. onTimelineChanged passes a copy of HlsManifest, from which you can access the media playlist, which has the property hasEndTag. Please update this issue if ExoPlayer is not behaving as expected.

I am using Wowza media server and unfortunately they have not implemented this tag yet. All they do is, remove the stream when Live event ended. We can only detect for 404 response code, perhaps through timer, which is not a good idea. :(

In my older app, in which I was using ExoPlayer 1.5.15, it used to trigger STATE_IDLE after few seconds when it does not receive any more stream data. In this version 2, it returns only STATE_BUFFERING even if there is no more stream data for longer period of time.

Is there any setting for idle state in duration of seconds in this version 2 library?

[ojw28]

No. You should ask Wowza to implement the HLS spec properly.

Wowza have not given any timeline yet for its implementation yet but they have added it in their to-do list since March last month and there is no update yet.

I have been using STATE_IDLE as an alternate solution in older 1.5.15 ver. I used to check for response code 404 in this state and display the notification. But this state is not triggering in this version 2 even for longer period of no stream data.

I am looking into exoplayer not transitioning into IDLE state after not being able to refresh the live window.
