[Gnash-dev] loading byte arrays or streams directly into gnash

I was interested in the possibility of using gnash as a gui widget to
load and display medical imaging clips.

So for example in an application a medical imaging application may have
multiple clips playing at once say 3x3 clips.  but you can dynamically
set the array size via menu selection.  The clips could at the extreme
be 1024x1024  pixels in size and come from JPEG compressed or
uncompressed source files, for example.  The clips could be up to 100
frames and play cyclically any where from 15 up to 60 frames per second.

Usually in Windows you would do this by having a bitmap object in memory
and have the object write to a device context on the screen.  Would
Gnash be a practical widget(instance per clip) to use in such an
application or are there are other basic approaches in the Gnu/Linux
world? Can a byte array or stream be directly loaded into Gnash instead
of something like a swf file? One of the reasons to do so is so one can
do image processing like brightness, contrast, high pass filtering, edge
effects etc so that externally you control and load the individual
frames.  Could Gnash be made to do image processing like mentioned and
dynamically?

Thanks, I am just exploring the issue for now.
