liblvc: Video goes black just before buffering

Postby fasteque » 09 Aug 2016 15:08

Hello all,

I've compiled libvlc for Android (https://wiki.videolan.org/AndroidCompile/) and I'm using the produced AAR (3.0.0-2.1.0) in my own application.

Everything works fine except on an HTC One M8 (Android 6.0 - HTC Sense 7.0), where sometimes, when the player needs to buffer, the video goes black. Then the playback continues without any issue, but it's annoying to see the screen black instead of the last played video frame.
On other devices/Android versions (i.e. Samsung S7 Edge - 6.0.1, Samsung S4 Mini - 4.4.2, Nexus 6 - 7.0) this issue is not reproducible.

I've tried to play the same video (4K video shot with a Sony Xperia Z5) using the VLC Player application, version 2.0.5, downloaded from Google Play and I can reproduce the issue as well.

You can find the video here: https://drive.google.com/open?id=0B935D ... 1p3aVNfUHc

Here's the log of: buffering > video playback > video goes black > buffering
