Unable to see MP4 video uBuntu

[seemantshankar]

I have a high end (8 CPU & 8 GB RAM) server installed with uBuntu. When I try to play a .MP4 video I can see that the progress bar in the bottom is moving but I cannot see or hear anything. All I get is a black background. I have manually installed and trusted the certificate within uBuntu. I am using VLC ver.2.2.0 which I installed using the official PPA. I have taken the log in Verbose 1 (Warnings) mode and here is what they look like...
