I was Playing a video in VLC but it displayed the error message
VLC does not support the audio or video format "MSS2"
How to solve this error
VLC does not support MSS2 codec for now. It should be supported in release 2.1 as can be seen from the comments here https://trac.videolan.org/vlc/ticket/750. The latest version available for download for now is 2.0.4. So wait for version 2.1 or try some other player for example MPlayer which supports MSS2 codec.
