[Rock-dev] Handling of Compressed Frames

[Matthias Goldhoorn]

Hi Again,
i currently working on some USB Based cameras where are the Frames 
Compressed.
This menas the size changes from image to image.
I have some conversion functions, so highlevel side is fine now.

The Question now is howto handle the data in rock:

1. extend the base/frame.h to handle compressed Frames
     a. iterator may be not working/dynamicly convert the image
     b. pixel/row-sizes may not be set or invalid
     c. new field "raw_image_size" is needed
     d. each frame needs an  "reinit" because the size changes (realtime 
problem??)
2. Convert in the producing module the Frame to RGB8
3. Add an new compressed_fram.h to base

What do you think?,
Matthias
