Hello Kushagra,

This is a very broad question which is probably why no one has responded
yet, we simply don't have a good answer for you. Based on a quick look at
that project it seems like it already supports LCDs, it is shown to work
with DVI signals. Do you believe that it doesn't?

As for a way to approach the problem, all I can offer are generic steps I'd
take to solve most problems. First, you have a working codebase which does
(almost?) what you want. Get it working and then study how it does the
signal processing. This will probably involve finding and understanding
some documents about the types of video signals which it supports decoding.
Then, if it doesn't do what you want, look for similar documents for the
video signals you want to decode and look at extending the module to
support the extra signal processing.

Regards,
Derek
