It looks like an issue specific to this class of videos.
Whether a video file is .avi or .mp4, it can have the audio/video compressed in
different ways.
Since the test video is 190MB, you can post the video details. Install _ffmpeg_
and run _ffmpeg -i myvideo.avi_.
Here is the output:

Here it says that the audio is compressed with AAC (VLC is fine with
that) and the video is compressed with h.264 (by an encoder created by
Citrix).
VLC (VLC media player 2.2.1 Terry Pratchett (Weatherwax) (revision
2.2.1-0-ga425c42)) did not work either for me; the audio was fine but no
video.
I was able to play the video with mplayer2 (command line player,
MPlayer2 2.0-728-g2c378c7-4build1 (C) 2000-2012 MPlayer Team) and ffplay
(command line player, ffplay version 2.7.6-0ubuntu0.15.10.1 Copyright
(c) 2003-2016 the FFmpeg developers). Both audio and video worked.
In addition, I managed to play the video in Totem (Ubuntu 15.10). Totem
is based on gstreamer, so gstreamer is also fine.
Therefore, the problem is likely to be with VLC and not the graphic drivers.
If you disable _Accelerated video output_ in VLC, the video still does not play
(audio is fine, but no output; just black).
