Exoplayer doesn't play Widevine HLS (no errors, no callbacks, only black screen)

[tipoc123]

[REQUIRED] Issue description

Exoplayer doesn't play Widevine HLS content (Axinom DRM). It shows only a black screen.

There are no errors in logcat. None of drm callbacks (onDrmSessionAcquired, onDrmSessionManagerError, onDrmKeysRestored, onDrmKeysRemoved, onDrmKeysLoaded, onDrmSessionReleased) are called (only onLoadStarted and onLoadCompleted).

The same content as Widevine DASH works fine.

[REQUIRED] Reproduction steps

Play content protected by Axinom DRM.

Sorry, no publicly available link, only playlists (mpd and m3u8 files): playlists.zip

I can send you mp4 files if you need it.

It sounds as if the key requests are not working for the Axinom servers for some reason. There are currently no callback events telling you that. This is tracked by #5399 and may be the reason why you don't see any events related to that.

If you can provide us with a working example (you can send it to dev.exoplayer@gmail.com), we can take a look and verify if that's the issue. Otherwise, you can also try to debug it yourself by checking which DrmSession calls are actually being made.

I've logged invokes of executeKeyRequest and executeProvisionRequest (methods in HttpMediaDrmCallback). 1) Widevine DASH - there are executeKeyRequest calls 2) Widevine HLS - there are NO executeKeyRequest calls

What else should I log?

[tonihei]

Looking at the provided HLS playlist, it seems to me that is does not contain any #EXT-X-KEY tag to define the initialization vector. You need to add this to support encryption.

[tipoc123]

You can see #EXT-X-KEY in stream_0.m3u8 and stream_1.m3u8 files.

Sorry, you're right. I was looking at the wrong place.

Could that be related to the issue in #6130? If the initialization segments don't load, the player will never reach the point where it tries to make the key requests.

No, we've already resolved that issue :)

Is it at all possible to get a publicly accessible example? There could be many issues which are difficult to see without actually stepping through the code ourselves.

I've sent you an email.

I managed to play both the provided DASH and HLS streams without any issues. In both cases I used the same drm configuration as discusses in the email thread. Given that it works fine in the ExoPlayer demo app, it's probably an app issue of some sort.

[tipoc123]

OK. I'll try again later and give you an answer.

Now it's working. The problem was in our playlist.
