[Ffmpeg-devel] Enhanced FLI/FLC Decoder Patch

Attached is my first patch against FFMPEG.
It provides for support of 15bpp FLX files (as generated) by Ulead Media
Studio Pro, and probably other programs.
It provides for support of the 15bpp/16bpp better compressed FLX files,
with the extensions created by Daves Targa Animator [DTA] (a program
from the early 90's).
Ive tested it against FLX's from Ulead. And FLX with DTA extensions
from EGI V4.00. (The only current programs I know that generate these
The next step, after this is accepted, if I can work out how, is to
integrate encoding of FLC(8Bpp), FLX (15Bpp), FLX+DTA(15/16/24Bpp) files.
Why would one do this. Well its not the worlds best codec, thats for
sure. But it is very easy to implement decoders. Those decoders
require very little in the way of CPU performance, and so it is an ideal
format for small embedded systems with small resolution LCD/LED Displays
(Where i primarily use them). Also, at 24Bpp it is a very fast (but
somewhat compressed) Lossless codec. Also FLC/FLX Excels with cartoon
style animation, where there are large chunks of the same colour, and it
doesnt introduce any noise artifacts at edges, for these types of files.
Note, I havent implemented 24Bpp in the Decoder yet, because i havent
ever seen a 24Bpp FLX. But the FLX format supports it, so when i do the
encoder, ill implement it then.
Ive read the MPlayer document on patches, and i believe mine complies
with the requirements.
