How to extends DefaultHlsExtractorFactory?

[goodibunakov]

Everywhere just write that it solves some problems with hls streams (#3712 (comment)). But how to realize this? Can somebody show the example?

[tonihei]

You can't extend it because it's final. But if you'd like to reuse the functionality, consider wrapping it in a new HlsExtractorsFactory.

[goodibunakov]

@tonihei actually i'd like to see example of realizing this #4861 (comment).

[tonihei]

These flags can be set when creating the DefaultHlsExtractorFactory in the constructor. Does that help?

[goodibunakov]

@tonihei May i use 2 flags for DefaultHlsExtractorFactory() constructor?

[tonihei]

Yes, these flags can be combined using the | operator.

[goodibunakov]

@tonihei i did:
DefaultHlsExtractorFactory defaultHlsExtractorFactory = new DefaultHlsExtractorFactory(FLAG_DETECT_ACCESS_UNITS | FLAG_ALLOW_NON_IDR_KEYFRAMES); Uri uri = Uri.parse(url); MediaSource mediaSource = new HlsMediaSource.Factory(dataSourceFactory) .setExtractorFactory(defaultHlsExtractorFactory) .setAllowChunklessPreparation(true) .createMediaSource(uri);
But my hls stream does not work. I get:

[tonihei]

Looks like your device may just not support this format. It would be helpful to get the output of the EventLogger. Can you attach one with player.addAnalyticsListener(new EventLogger(trackSelector));?

If i missed something, here is full log file log android6.txt

[tonihei]

There should be more logging especially about tracks, state changes etc. Can you enable the INFO log level for the output? Or even better, provide a full bugreport (with "adb bugreport").

[goodibunakov]

There was not any state changes as i think, playback does not start. We have "loading" and then onPlayerError.
Help me, where i have to enable INFO log? Or how to provide a full bug report?..

[tonihei]

https://developer.android.com/studio/debug/bug-report

[goodibunakov]

I hope this helps bugreport-2018-11-22-11-12-54.txt

[tonihei]

That bug report doesn't contain the failing playback. Can you try to get one immediately after the error occured? And also with the EventLogger attached.

[goodibunakov]

I did:
eventLogger = new EventLogger(defaultTrackSelector); player.addAnalyticsListener(eventLogger);

I get:
Logs logs.txt

XML
<com.google.android.exoplayer2.ui.PlayerView android:id="@+id/video_view" android:layout_width="match_parent" android:layout_height="190dp" app:auto_show="false" app:controller_layout_id="@layout/exo_playback_control_view" app:resize_mode="fill"/>

where {INPUT} is a stream from a video camera in the rtsp format.

[tonihei]

The logs still don't tell anything new. But as said above, I suspect the device doesn't support the video resolution (2688x1520) and there is probably nothing we can do about that.

[goodibunakov]

Well, i took logs from Logcat. Why there does not shows what you need?

And may be we have to correct our m3u8 for success on this phone?

I also need to fix to not receive onPlayerError on other devices. I get it so often.

[tonihei]

We can't help you with content creation, but it's usually a good idea to have multiple formats (including low-res formats) such that all devices support at least one of them.

Why there does not shows what you need?

I was looking for the list of available formats and whether they are supported. This list should be reported when using the EventLogger. But it's not part of your logs.

[goodibunakov]

What should i do besides this: eventLogger = new EventLogger(defaultTrackSelector); player.addAnalyticsListener(eventLogger); ?

[tonihei]

Have you done this before calling player.prepare? That could be a reason for not reporting everything.

[goodibunakov]

logs.txt

Now I did addAnalyticsListener after prepare.
