[Opensvcdecoder-support] MGS support

[hothaifa <alq...@ms...>]

Dear colleagues,

I'm trying to create a video with 6 SNR layers using MGS (Not possible 
using CGS because only 3 layers are supported by JSVM). i'm having a 
problem when decoding the stream (No output). Is MGS still unsupported 
in Open SVC Decoder ?. Below is my JSVM configuration
