VLC Unity crash after several video

The application crashed after several video was played. Crash visible on S8 and Oculus GO.

Can't see any crash error log in logcat with Unity, VLC, or vlcunity

Repository sample is available here: https://bitbucket.org/Lostyn/sampleunityvlc

Medias folder content must be put on device at in the Movies folder. Media are play from local drive.

Looking for good idea or solution !
