Which wrapper are you using for libvlc on android?

In any case you should probably look at video track information and how to switch video track.
this is how vlc-android does it https://code.videolan.org/videolan/vlc- ... yer.c#L761
libvlc doc to set the track https://www.videolan.org/developers/vlc ... 92d3f41520
