Easiest way to develop new custom codec on DM6467T EVM (aka Spectrum Digital HD1080P)

(Please note that this is a breakout thread from http://e2e.ti.com/support/embedded/f/356/p/86363/298144.aspx#298144)

I'm developing a new codec for the DM6467T, and developing using the corresponding EVM.  I'll probably get my 'baseline' situation running with the encode+decode demo codec(s) that come with the EVM (aka Spectrum Digital HD1080P).  Next I need to integrate my own codec.  In a perfect world, (A) I have source code for my placeholder codec, (B) I compile, install, and confirm operation of my newly compiled version of the codec, (C) I replace the source code guts with my own codec source that I've developed in the past.  However, there's a possible issue about source code.  Spectrum Digital provides some source code, but I suspect it's only for hardware level testing of some things.  It's *not* the source code to the demo suite.  

What's the best way to navigate this step, or what's the best way to locate the perfect world situation I described?

Thanks,

Helmut

    I'm still searching for answers.  Hopefully someone just back from the New Year holiday might be able to help me.  To date, I haven't really gotten anywhere, even though I've learned a lot.  I just know more of how I don't know what to do next!

    I think I need source code to a XDAIS codec example, running under the Codec Engine, running under Linux.  I need to know how to get this onto the DM6467T EVM, and then how to debug it using CCS.  I have in the past done codec authoring and CCS debugging on the prior version of my codec, using a third party smart camera system based on the DM6446.  I'm simply looking to get that same code running on the DM6467T EVM.  However, that third party smart camera came with an existing CCS project that I simply compiled, edited the codec example code, and programmed to the camera using either CCS or an Internet connection and custom program.  I never had to get into Linux, it had no hard disk, I don't know if it had a file system, etc.

    So now it looks like a mountain to climb before I can get to this point again.  I'm looking to be transported to the top of the mountain, or else told some shortcuts and pointed to the right tools to get me there quickly, if possible, please.

    The best case for me would be a NAND image including all boot and file system stuff necessary to auto-run a single custom encode-decode codec upon powerup.  That's all my application needs to do.  The encode-decode codec is my own code, of course, and therefore some customization of the image is required.  My searching on the wiki and forum haven't yielded anything close yet.
