- Intro
- =====
-
- This is the second release of the first public domain MPEG viewer
- for the Commodore Amiga. Please also read the file "README" for
- some general information about this software.
-
- Changes against V1.21 (first release):
-
- - Now runs on OS2.0 and up
- - Now needs reqtools.library
- - Screen mode & depth choosable
- - Version string (1.22)
-
- I had to implement sort of a color allocation scheme for 2.x like
- OS3.x has. It isn't perfect yet, but it seems to work ok.
-
- I have now included a version which will run on any processor.
- Don't expect miracles on a 68000.

- Amiga Specials
- ==============
-
- The Amiga version of this player has (up to now) one additional
- option called "-amiga window", that tells the player to open it's
- output window on your workbench (better: default public screen).
- Otherwise it will prompt you to specify the screen mode, depth
- and size of the custom screen, the animation should be displayed
- on.
-
- If opening on workbench, you'll get the better results the deeper
- your workbench screen is (pen sharing: the player tries to
- allocate 128 colors).
-
- There's still no HAM support, but I'll think about it.
-
-
- Amiga Bugs
- ==========
-
- Bugs? In *my* code? You must be kidding! Er... okay, ahem. :*)
-
- The breaking problem seems to be gone - but you never know...
-
- Mono dithering isn't functional yet.
-
-
- Speed
- =====
-
- Don't expect this player to be the Speedy Gonzales of anim
- players. On an Amiga 4000, you get a maximum of about 5.4 frames
- per second (dithering gray on 128 colors NTSC lores screen).
-
- Nevertheless, this release of the player is on my A4000 nearly as
- fast as on a SUN Sparcstation IPC. I think, many time is spent
- converting the data to plane format. I would love to see future
- Amigas using byte-per-pixel-modes...
-
-
- Source
- ======
-
- I included the necessary X11 header files (don't think, many
- Amiga programmers have them around). The Makefile and code are
- for Markus Wild's port of the famous GNU GCC C compiler (thanks
- again, Markus!). Don't forget to build an amiga.lib version 39.x
- for your GCC before trying to compile the code.
