This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

MPEG Video Software Decoder
(Version 2.1; Feb 1 1995)

Computer Science Division-EECS, Univ. of Calif. at Berkeley
RISC OS version 1.0 (Apr 13 1995)
Description
-----------
This is a port of the MPEG Video Software Decoder, as released by the
University of California at Berkeley. The decoder can be used in two
ways:
1. After the !MPEGplay directory has been seen by the filer, double
clicking on a MPEG file (filetype &BF8, or simply MPEG) will
start playback.
2. By means of the !MPEGplay application. After this application has been
started, all playback is handled through this program. The main task
of !MPEGplay is to provide a quick way of setting the command line
options of the decoder. As an extra option, it offers the possibility
to enter the preferred screenmode for playback. Double clicking on or
dragging a MPEG file to the iconbar icon, will start playback.
This version is not optimal though:
- Support for RISC OS 3.50 is minimal. It's not possible to enter mode
strings yet. As I own a 'humble' RISC OS 3.10 machine, I can't test this.
In the future it will be included, of course.
- I will soon replace the existing DCT routines in the decoder by faster
(ARM coded) routines.
- Better support for the Computer Concept's ColourCard and the new
improved video hardware of the Risc PCs. I have seen a version for a
Risc PC fitted with VRAM, which displayed the MPEG stream by directly
writing to VRAM. If people like this idea, it can be included.
Note: this port is partly based on the work done by Paul LeBeau. However,
his port is dated somewhere in 1993, and I decided it was time for a new
version. This was also caused by the fact, that Berkeley has just released
the decoder as part of a number of tools:
mpegplay - software-only MPEG-1 video decoder
mpegencode - software-only MPEG-1 video encoder
mpegstat - a bitstream analysis tool
mpegblocks - an interactive tool to examine macroblock coding
mpegbits - an interactive to examine bit allocation to blocks
I'm planning to port all these programs to the Acorn Archimedes/RiscPC
platform. I have also the source code of a MPEG sound player. As it's
difficult to handle playback of these samples in real-time on a RISC OS
machine, I would like to get in touch with people interesting in making
this work.

Usage
-----
mpegplay [ -nob ] [ -nop ] [ -loop ] [ -start num ] [ -end num ]
[ -gamma num ] [ -at xpos,ypos ] [ -leave ] [ file_name ]
Options
-------
-nob
Causes the player to ignore and not display any B frames.
-nop
Causes the player to ignore and not display any P frames.
-loop
Makes the player loop back to the beginning after reaching the end.
-start num
Waits to start display until this frame number (previous frames are parsed).
-end num
Ends display at this frame number (continues parsing, for no good reason).
-gamma num
Gamma correction. Raise the luminance component of each pixel to num.
-at xpos,ypos
Postition the bottom-left corner of the displayed MPEG stream at these
coordinates (in OS units).
-leave
Leave last frame on screen when movie finishes.
Notes
-----
The player expects video streams only. It can handle multiplexed MPEG
streams (video+audio streams) by discarding the audio.
Some streams do not end with the proper sequence end code and will probably
generate an "Improper sequence end code." error when done playing.
This player can play XING data files. Be aware that XING makes no use of
temporal redundancy or motion vector information. In other words, they do
not use any P or B frames in their streams. Instead, XING data is simply a
sequence of I frames. Since I frames take significantly longer to decode,
performance of the player using XING data is not representative of the
player's ability.
