Short: MPEG-2 video player (040/60/PPC)
Author: thorgal@amiga.com.pl
Uploader: thorgal@amiga.com.pl
Type: gfx/show
This is a preliminary release of Frogger - MPEG video player that supports
both MPEG-1 and MPEG-2. It is based on source code from MPEG Software
Simulation Group with quite some speedwise optimizations by me. Currently
it still is very slow and I guess it will only be of interest to 060/PPC
users.
Although there are other MPEG players available for PowerPC, I suggest that
you try this one - its stream parser is of exceptional quality and I yet
have to find standard-conforming MPEG stream that fails to work with
Frogger.
------------------------------------------------------------------------------
Frogger plays in a window on Workbench and uses only 8-bit output, which
however is much better looking than that of other MPEG players due to very
well designed palette. Full quality can be only achieved if you have at
least 224 free pens on WB, so please run it on 256 color WB. Frogger uses
WritePixelArray8() call, so AGA users are advised to install some speedup
patch, like Michael van Elst's excellent NewWPA8 from Aminet.
In the archive you will find two versions - 040 and PPC. I left out 060
version because speed difference between it and 040 one was unmeasurable.
Usage:
frogger -o4 -b <filename>
and on PPC
runelf frogger.elf -o4 -b <filename>
Have fun,
Milek
------------------------------------------------------------------------------
Some things Frogger will support in the future:
- 15/16/24-bit screens,
- scalable output,
- video hardware of CV64/3D and CVPPC
- sound
- framerate control and frame dropping
- random-access slider
- and of course MORE SPEED! :)

Thanks to:
Marcin Orlowski for letting me debug Frogger on his CS PPC (I'm still a
060 user :( ).
Steve Krueger for his continued work on SAS/C.
