I just downloaded and looked at the SDK AAF 1.1, so I'm pretty new to the SDK and still learning about it.  I was hoping that experienced users would please point me to a right direction.

I have a few questions if you please would point me or give your inputs:

1.  I have a series of NITF files (the basic format of NITF file is that it contains a header metadata, and one or more images with metadata).  Can I add one or more NITF files as essences to the AAF file?

2.  I look at the sample codes, it looks like you can add MPEG and JPEG  files?  These already have the plugin codecs.  So, does it mean that I have to implement my own plugin if I want to add NITF files to AAF?  Please explain.

3.  Can I not implement the plugin codec for NITF?  can I just wrap them as files into AAF?   Or does AAF has to understand the file format for all files inserted?

4.  Is there anyways that I can tell AAF the general format or default format when adding the samples? 

I'm not sure if I make any senses, but please provide your inputs.  I'll verify and confirm for any unclear points.

Any help would be appreciated.

Thank you.
