- Now there is the MPEG AUdio Player for Win3.1 !
-
- This program is Shareware. To encode your own MPEG Audio files, you need
- to buy the MPEG Audio Software Encoder program for Win3.1 .
-
- [ Look above. Get some freeware encoder in software, much better !]

- [The June 30 edition of mpeg2w11 does not contain encoder port]
-
- MPEG Software Simulation Group codecs
- for Windows 32s
- (MPEG-L@netcom.com)
-
- MPEG2DEC.EXE and MPEG2ENC.EXE are Windows 32s ports with integrated
- display functions of the MPEG Software Simulation Group's programs.
-
- MPEG2PLY.EXE is the port of mpeg2play---Stefan Eckart's variation of
- mpeg2decode which optimizes speed through fast decoding methods such as
- approximation techniques, loop unravelling, et al.
-
- All Win32s programs were ported with Microsoft Visual C++. Only the
- main() program and display files (mpeg2dec.c, mpeg2enc.c, or mpeg2ply.c)
- differ from the standard "Unix distribution."
-
- If you do not have a 32-bit Windows environment (e.g. Win 4.0 Chicago,
- Windows NT), but plain old Windows 16 (e.g. Windows 3.1), yet you do
- possess either a 386, 486, or Pentium-based PC, you can download the
- Microsoft 32-bit extension program, "Win32s" from the Microsoft FTP

- About the windows icon:
- The 32x32 4-bit icon for MPEG2DEC.EXE and MPEG2ENC.EXE is a silhouette

-
- MPEGPLAY V1.61 (c) 1993,1994 Michael Simmons
-
- Please READ ALL of this file!
-
- This is Release Version 1.61 of my port of the Berkeley mpeg player.
-
- Note this version requires the WIN32s V1.15a Windows(tm) Extender.
- Also this version will only work under (beta 612) of Windows NT(tm) V3.5 or later.
-
- Features added in this version include
- (1) Support for MPEG1 System Layer files (you don't have to split them now).
- (2) Support for the Microsoft(tm) WinG(tm) Windows(tm) gaming library.
- (3) Improved colours for the Ordered and 2x2 Order dithers.
- (4) "Save As" For all the Mosaic Users.
- (5) Improved Error handling for corrupt/non standard mpeg files.
- (6) Support for CDI(tm) and VideoCD Streams. Either as an extracted MPEG
- sequence or as a RAW CDROM grab.
- (7) Recompiled using the Microsoft Daytona(tm?) (beta 612) SDK Compiler.
-
- Please Email me with any suggestions you may have on improving the player!
- (See the section CONTACTING ME).
-
- This player can play standard mpeg files that include P and B frame
- encoding, and large 354x288 movie files.
- It has several display options including mono, gray scale, color dither and
- Full colour (for Hicolor graphic cards).
- 8MB of Ram or greater is recommended if large Image size MPEG files
- are played.
-
- This program is SHAREWARE Please read the REGISTER.TXT file for
- information on registering your copy.
-
- To install the player.
- If you don't have Win32s V1.15a installed, install it first.
- Unzip the file disk1.zip to a floppy disk.
- Then run the setup.exe file via the Progman File-Run Menu
- Item.
- Note: This will also install the Microsoft WinG(tm) extensions to Windows(tm)
- Should you wish to remove these extensions at a later date
- please refer to the section near the end of this Readme.txt file.
-
- Read the Disclaimer in the online Help before loading any mpeg movie files.
-
- The latest version of this software can be found first on
-
- URL=ftp://ftp.ecel.uwa.edu.au/users/michael/
-
- UNREGISTERED VERSION LIMITATIONS:
- The unregistered version will display the About box at startup.
- IT WILL ALSO NOT HANDLE FILES BIGGER THAN 1MB!
-
- DISTRIBUTION:
-
- The Unregistered Version of the Player may be freely Re-Distributed so long as
- (1) None of the files are modified.
- (2) All files in this archive are re-distributed together.
- (3) None of the files are removed from this archive.
- (4) It is clearly stated that this program is Shareware, extended use of
- which requires payment to myself Michael Simmons as described in the
- players about box and the REGISTER.TXT file.
- (5) If any additional files are added it must be clearly stated
- which files have been added, who added these files and why!.
- It must be stated that I "Michael Simmons" am in no way responsible
- for these additional files.
- (6) None of the added files can instruct the user or modify the player
- in any way possible to enable the Unregistered Version Limitations
- to be overcome.
-
- The Registered Version may only be Re-Distributed with my written
- approval.
-
- KNOWN BUGS:
- The player does not like certain PD/Shareware desktop addons (Clocks etc).
- A small number of people are getting a GPF in POINTER.DLL. If you have
- this problem and solve it please contact me. So far I can not reproduce
- the fault.
- The player does not multitask while scanning a file to determine whether
- or not it is a system layer or straight video file. This is only a problem
- on large misaligned RAW CDI or VideoCD grabs.
- RAW CDI or VideoCD grabs have only be tested on 4 CDI Disks. Given the
- variation found between these disks I would not be surprised if there
- are problems with some disks.
- If you are having a problem with a certain CDI/VideoCD disk please send a
- copy (both original CD's) of it to me. If I don't already have it I will treat
- it as a registration fee.
- If you have a problem and are really stuck
- try and find a machine on which it works and compare the two configurations.
- If you really really get stuck then see the section CONTACTING ME.

-
- This version of the Berkeley MPEG Tools packages together the decoder

- and over 15,000 copies of the encoder have been FTP'd since it was released
- in July 1993.

- MPEG-1 Video Software Encoder
- (Version 1.5; May 8, 1995)
-
- Lawrence A. Rowe, Kevin Gong, Eugene Hung, Ketan Patel, Steve Smoot
- and Dan Wallach
- Computer Science Division-EECS, Univ. of Calif. at Berkeley
-
- This directory contains the freely distributed Berkeley MPEG-1 Video
- Encoder. The encoder implements the standard described in the ISO/IEC
- International Standard 11172-2. The code has been compiled and tested
- on the following platforms:
-
- DECstation 5000 and Alpha
- HP PA-RISC (HP/UX 9.X) (i.e., HP 9000/7XX and 9000/3XX)
- SGI Indigo running IRIX 5.0.1
- Sun Sparc (SunOS 4.X)
-
- In addition, Rainer Menes from the Technical University of Munich has
- ported the encoder and decoder to the Macintosh. You can get that code
- directly from him (menes@statistik.tu-muenchen.de), or from the
- Berkeley FTP archive (mm-ftp.CS.Berkeley.EDU). If you decide to port
- the code to a new architecture, please let us know so that we can
- incorporate the changes into our sources.
-
- This directory contains everything required to build the encoder
- and run it. We have included source code, makefiles, binaries
- for selected platforms, documentation, and test data. Installation
- instructions are given in the file named src/mpeg_encode/INSTALL. A man
- page is given in the file doc/mpeg_encode.1. A detailed user
- manual is provided in postscript format in the file doc/user-manual.ps.
-
- The encoder will accept any input file format as long as you provide
- a script to convert the images to PPM, YUV, JPEG, or JMOVIE format. Input
- file processing is described in the file doc/INPUT.FORMAT. Options to
- control input file processing and compression parameters are specified in
- a parameter file. Very little error processing is done when reading
- this file. We suggest you start with the sample parameter file
- examples/template.param and modify it. See also examples/default.param.
-
- The convert directory of Mpeg-Tools contains utilities you might find
- useful including:
-
- programs to do PPM/YUV conversion and programs to convert Parallax
- XVideo JPEG files into PPM, YUV, or JPEG frames.
-
- The motion vector search window can be specified, including half-pixel
- block matching, in the parameter file. We have implemented several
- search algorithms for P-frames including: 1) exhaustive search,
- 2) subsampled search, and 3) logarithmic search. We have also implemented
- several alternatives for B-frame block matching including: 1) interpolate
- best forward and best backward block, 2) find backward block for best
- forward or vice-versa (called CROSS2), and 3) exhaustive cross product
- (i.e., go out for coffee and a donut!). The search algorithms are controlled
- by options in the parameters file. For tips on choosing the right search
- technique, see the user manual.
-
- The encoder can be run on one computer (i.e., sequential) or on several
- computers (i.e., parallel). Our goal is to produce a portable, easy-to-use
- encoder that we can use to encode large volumes of video material for
- the Berkeley VOD system (see paper VodsProp93.ps.Z on the FTP archive).
- The parallelism is done on a sequence of pictures. In other words, you
- can spawn one or more children to encode continuous runs pictures. The
- uncompressed data can be accessed either through NFS or TCP sockets.
- The goal is to allow you to encode using multiple processors, think
- spare cycles on workstations, to speed up the encoding time. Although
- performance depends on the speed of individual processors, the file system
- and network, and the P/B frame search methods, we have encoded 3.75
- frames/second on 8 HP Snakes running in parallel as compared with 0.6
- frames/second on 1 Snake. These are preliminary results. We are continuing
- to experiment with and tune the code. Instructions to run the parallel system
- are given in the man page and the parallel.param example parameter file.
-
- We have done some tuning to produce a reasonable encoder, but there are
- many more optimizations that we would like to incorporate. These
- extensions are listed in the file doc/EXTENSIONS. If you succeed in
- implementing any of them, please let us know!

-
- MPEG Video Software Decoder
- (Version 2.1; May 1 1995)
-
- Lawrence A. Rowe, Ketan Patel, Brian Smith, Steve Smoot, and Eugene Hung
- Computer Science Division-EECS, Univ. of Calif. at Berkeley
-
- This directory contains a public domain MPEG video software
- decoder. The decoder is implemented as a library that will
- take a video stream and display it in an X window on an 8, 24
- or 32 bit deep display. The main routine is supplied to
- demonstrate the use of the decoder library. Several dithering
- algorithms are supplied based on the Floyd-Steinberg, ordered
- dither, and half-toning algorithms that tradeoff quality and
- performance. Neither the library nor the main routine handle
- real-time synchronization or audio streams.
-
- The decoder implements the standard described in the Committee
- Draft ISO/IEC CD 11172 dated December 6, 1991 which is
- sometimes refered to as "Paris Format." The code has been
- compiled and tested on the following platforms:
-
- HP PA-RISC (HP/UX 9.X, X11R5) (i.e., HP 9000/7XX and 9000/3XX)
- Sun Sparc (SunOS 4.X, X11R5)
- DECstation 5000 and Alpha
- Silicon Graphics Indigo
- MIPS RISC/os 4.51
-
- If you decide to port the code to a new architecture, please let
- us know if there are any significant changes, so that we can incorporate
- them into our sources.
-
- This directory contains everything required to build and
- display video. We have included source code, a makefile, an Imakefile,
- installation instructions, and a man page. Data files can
- be obtained from the same ftp site this was located in.
- See the INSTALL file for instructions on how to
- compile and run the decoder.
-
- The data files were produced by XING. XING data does not take
- advantage of P or B frames (ie, frames with motion compensation).
- Performance of the player on XING data is significantly slower
- (half or less) than the performance when motion compensated MPEG
- data is decoded. We are very interested in running the software
- on other MPEG streams. Please contact us if you have a stream
- that does not decode correctly. Also, please send us new streams
- produced by others that do utilize P and B frames.
-
- Our future plans include porting the decoder to run on other
- platforms, integrating it into a video playback system that
- supports real-time synchronization and audio streams, and
- further experiments to improve the performance of the
- decoder. Vendors or other organizations interested in supporting
- this research or discussing other aspects of this project should
- contact Larry Rowe at Rowe@CS.Berkeley.EDU.
-
- Other Versions:
- There are three variations of the old mpeg_play:
- One added a very nice Motif interface (variously named
- mpeg_play-2.0.1 and xmpegplay).
- One was mpegvga.patch and let linux play straight to a VC.
- One was an X interface (mpegplayer.tar.gz on linux sites)
- We have notified the authors of those programs, and will
- have new versions of them here as soon as they can find the time
- to update them.
-
-

-
- This directory contains a public domain tool to monitor and modify
- MPEG video streams. mpeg_bits takes as input an mpeg stream and
- presents graphical feedback on the distribution of bits in the
- stream, on a macroblock-by-macroblock level. mpeg_bits also provides
- a simple user interface to generate specifics files that can be
- used by mpeg_encode to re-encode a stream, modifying the encoding
- on a macroblock-by-macroblock level. [The present version of mpeg_encode
- does not support this..]
-
- This tool does not support system layer streams.
-
- mpeg_bits supports the standard described in the Committee
- Draft ISO/IEC CD 11172 dated December 6, 1991 which is
- sometimes refered to as "Paris Format." The code has been
- compiled and tested at least once on the following platforms:
-
- HP PA-RISC (HP/UX 9.X, X11R5) (i.e., HP 9000/7XX and 9000/3XX)
- Sun Sparc (SunOS 4.X, X11R5)

- mpeg_bits. We have included source code, a makefile, installation
- instructions, and a man page.
-
- See the INSTALL file for instructions on how to
- compile and run the analyzer.
-
- Our future plans consist of more fully supporting an interactive
- editor paradigm; specifying changes directly on the display,
- seeing the results of edits on the video stream immediately
- as they occur, etc. We would also like to port the code to
- run on more platforms, and add support for system layer streams.

- ~Subject: xmg
-
- XMG v1.0 - The X MPEG Grabber
- *******************************
-
- DESCRIPTION
- +++++++++++
-
- XMG is a utility for the X Window System which allows you to create MPEG-1 video streams by repeatedly
- grabbing a window on the screen and then joining the frames into an MPEG sequence. XMG has several
- options that modify its behaviour, but it also provides sensible defaults for most of them. The two switches that
- you'll use most of the time are -fps (or -fpm) and -frames. These specify the number of frames per second (or
- per minute) and the total number of frames to grab. Here's an example invocation :
-
- xmg -fps 1 -frames 20
-
- This specifies that we want to grab 20 frames, one per second, and also that we want to see what's going on
- during the grabbing process. At this point the XMG window will appear :
-
-
-
- Click on the "Grab" button and then click with the left mouse button inside the window that you want to grab.
- Once you've done this, the grabbing process will begin immediately, displaying some progress information as
- it does it. It is possible to change a few parameters directly from inside the window, instead of specifying them
- on the command line. When all the frames have been grabbed, the MPEG encoding process begins: go off and
- make yourself a nice cup of tea and come back later. By default the program creates a file called xmgout.mpg
- in the current directory. This file can then be viewed with any MPEG player which supports I,P and B frames
- of any size (Xing for example, doesn't support them). You can specify a different name for the output file with
- the -output switch. For example, the command :
-
- xmg -fps 1 -frames 20 -output mympeg.mpg
-
- will create a file called mympeg.mpg. When XMG is grabbing the frames, it stores them in a temporary RLE
- compressed and archived format called XLA. This file can become quite large very quickly, especially if you're
- grabbing several frames of a certain size. This file will be created by default in the /tmp directory with the
- name xmgtmp.$$$. This can be changed with the -tmp option :
-
- xmg -fps 1 -frames 20 -tmp /empty/xmpeggrab.tmp
-
- which will create it in the /empty directory with the name xmpeggrab.tmp. Make sure you've got plenty of
- space on the device ! To actually perform the encoding, XMG requires a parameter file. By default this file is
- called xmg.param and has to be in the current directory. Don't worry if you haven't got one : XMG will create
- a default one for you and use that. A different parameter file can be specified with the -param switch :
-
- xmg -fps 1 -frames 20 -param flower.param
-
- This will use the file flower.param. A description of the possible contents of the paramter file is provided later
- on.
-
- SYNOPSIS
- ++++++++
-
- xmg
- -help
- -display host:dpy
- -frames nframes
- -fps nfps
- -fpm nfpm
- -terse
- -output filename
- -tmp filename
- -param filename
-
- OPTIONS
- +++++++
-
- -fps nfps : specifies the number of frames per second to grab. Even if the machine you're using is slow, XMG
- will grab the server during the grab, so that no other application can write to the screen at the same time. As
- soon as the frame has been grabbed, the server is released so that the other applications can redraw their client
- area.
-
- -fpm nfpm : specifies the number of frames per minute to grab.
-
- -frames nframes : specifies the number of frames to grab in total.
-
- -output filename : specifies a name and location for the generated MPEG stream. By default XMG creates a
- file in the current directory called xmgout.mpg.
-
- -tmp filename : specifies a name and location for the temporary storage of the grabbed frames. This file is
- deleted when XMG has completed the encoding process. The default is /tmp/xmgtmp.$$$
-
- -terse : does not display the XMG status window during the grabbing/encoding process. The default is to
- display the XMG window.
-
- -param : specifies a name and location for the parameter file. By default the file is called xmg.param and has to
- be in the current directory. If one doesn't exist, a default one will be created for you.
-
- PARAMETER FILE
- ++++++++++++++
-
- The parameter file MUST contain the following lines :
-
- PATTERN pattern
- ---------------
-
- pattern is a sequence of I's, P's and B's, that specifies the order of the frames in the MPEG stream.
-
- GOP_SIZE n
- ----------
-
- n is roughly the number of frames in a Group of Pictures (roughly because a GOP must begin with an I-frame)
-
- SLICES_PER_FRAME n
- ------------------
-
- n is roughly the number of slices per frame. Note, at least one MPEG player may complain if slices do not start
- at the left side of an image. To ensure this does not happen, make sure the number of rows is divisible by
- SLICES_PER_FRAME.
-
- PIXEL (FULL or HALF)
- --------------------
-
- use half-pixel motion vectors, or only full-pixel ones
-
- RANGE
- ------
-
- use a search range of +/- n pixels
-
- PSEARCH_ALG algorithm
- ---------------------
-
- algorithm must be one of {EXHAUSTIVE, TWOLEVEL, SUBSAMPLE, LOGARITHMIC}. Tells what kind
- of search procedure should be used for P-frames. Exhaustive gives the best compression, but logarithmic is the
- fastest. You select the desired combination of speed and compression. TWOLEVEL is an exhaustive full-pixel
- search, followed by a local half- pixel search around the best full-pixel vector (the PIXEL option is ignored
- for this search algorithm). BSEARCH_ALG algorithm must be one of {SIMPLE, CROSS2, EXHAUSTIVE}.
- Tells what kind of search procedure should be used for B-frames. Simple means find best forward and
- backward vectors, then interpolate. Cross2 means find those two vectors, then see what backward vector best
- matches the best forward vector, and vice versa. Exhaustive does an n-squared search and is EXTREMELY
- slow in relation to the others (Cross2 is about twice as slow as Simple).
-
- IQSCALE
- -------
-
- use n as the qscale for I-frames
-
- PQSCALE
- -------
-
- use n as the qscale for P-frames
-
- BQSCALE
- -------
-
- use n as the qscale for B-frames
-
- REFERENCE_FRAME (ORIGINAL or DECODED)
- -------------------------------------
-
- If ORIGINAL is specified, then the original images are used when computing motion vectors. To be more
- accurate, use DECODED, in which the decoded images are used. This should increase the quality of the image,
- but will take a bit longer to encode.
-
- The lines may appear in any order, except the following exceptions.
-
- NOTES
- +++++
-
- If XMG was compiled with the -DMITSHM switch enabled, then shared memory will be used if available and
- will increase performance noticeably.

-
- [ mpegstat.tar.Z was uploaded to mm-ftp.cs.berkeley.edu, the DOS-port ]
- [ is available on http://www.powerweb.de/mpeg ]
- [ It will probably included in the next version of Berkeley's encoder ]
-
- This is mpegstat v1.0 - an analyzing took for MPEG-I video streams for Unix.
- It is based on the Berkeley MPEG player v2.0, utilizing the Berkeley parsing
- and decoding routines for the MPEG data stream.
-
-
- MPEGSTAT is a useful utility for analyzing MPEG-I video
- streams. It is based on the Berkeley MPEG movie player.
- MPEGSTAT reads a video stream from a file or stdin and
- shows the frame type pattern as it is found while parsing.
- After the stream is completely parsed it displays the
- frame pattern as it would be displayed by a MPEG viewer.
- It then generates a summary of various mpeg format related
- statistics. MPEGSTAT works for MPEG movies that are Paris
- format compatible.

-
- Hello all.
-
- This is an announcing for all of those that have already been waiting
- on the release of my code for multiplexing one MPEG 1 Audio and one
- MPEG 1 Video Stream into a MPEG 1/SYSTEMS multiplexed data stream
- according to the ISO/IEC 11172-1 specs. Sorry for all of those that
- needed the code really bad and kept mailing me on it. I couldn't hold
- my promises because of copyright release on part of the University.
-
- But here it is: I uploaded the source code on
-
- URL=ftp://hpsystem2.informatik.tu-muenchen.de//pub/comp/graphics/mpeg/mplex/mplex-1.0beta.tar.gz
- [131.159.0.198]
- ftp.informatik.tu-muenchen.de
-
- .gz means it is compressed with GNU zip. Should somebody not have it,
- you can find it on our FTP server under
-
- /pub/comp/gnu/gzip/
-
- else, just try
-
- get mplex-1.0beta.tar.Z
-
- Our FTP server will do an on-the-fly-compressing with the 'compress'
- (.Z) format.
-
-
- Now to the code itself:
-
- I have been kept really busy with my papers on multiplexing (they will
- shortly be available on the FTP server also, I will post on that), so
- sorry if I couldn'g tighten the code up a bit. There is no real docu-
- mentation yet, please try out the code. Feel free to email me for any
- further questions.
-
- As of now, this code will only run under standard UN*X-Style platforms
- providing a (K&R-Style) C compiler (GNU CC is fine). It tested fine on
- SUN's, HEWLETT PACKARD's series 700, SILICON GRAPHICS machine's.
- There is * NO DOS PORT AVAILABLE (YET) *.
-
- Contact me if you are planning such a thing.
-
- There will be better releases, and I promise to clean up the code soon.
-
- :)
-
- This Software is released under the terms of the GNU public license,
- see the tar archive for further details. Feel free to archive the code
- on other FTP servers or post it to newsgroups, if there is such
- interest.

-
- [ Here it is !! The first, fully-featured MPEG-player with X11-interface. ]
- [ XMPLAY exists currently in Version 1.0, patches are available. The next ]
- [ Version 1.1 is currently in development. Thats the announcement ! ]
-
- XMPLAY [Version 1.1] - Sun Apr 10 14:51:22 MDT 1994
-
- This distribution is the result of a project worked out at the
- Technical University (TU) Berlin, held in Winter 93/94 by
- Tom Pfeifer. The basic idea is created by Frank Gadegast,
- the programing work was then done by Juergen Meyer, Metin
- Cetinkaya and Frank Gadegast.
-
- This software is ftp-able from:
-
- http://www.powerweb.de/mpeg
-
- [ Just to remember .gz means, its compressed using GNU's zip, called ]
- [ gzip. Use gunzip to uncompress. ]
-
-
- XMPLAY [Version 1.1]
-
- <IMG SRC="xmplay1.gif"> <IMG SRC="xmplay2.gif">
-
- XMPLAY is a very nice directory-browser under X11 to use XMPEG,
- the interactive X11-MPEG-player.
-
- MPEG is a video-format described by the ISO-standard ISO CD11172.
- This implementation here can handle MPEG-stream written down
- at the MPEG-group-meeting in Paris '92. It can handle IPB-frames
- but no system- nor audio-information.
-
- <IMG SRC="xmplay3.gif"> <IMG SRC="xmplay4.gif">
-
- Additional you get a little utility called MPEGINFO, showing you, if called
- with the filename of a MPEG-file the most important parameter it can read
- dirrectly from its header, like size, picture rate or frame-style.
-
- It should work under nearly every system, 'cause it's programed without
- MOTIF, the X11-Toolit or other stupid things, that are always causing
- problems. It only needs the X11-library, no matter if you're using
- Release 3, 4 or Release 5.
-
- In addition it has lots of defines to let it run under BSD, SYSV, ISC,
- Solaris, SunOS, A/UX, SCO or XENIX and you don't have to hack a difficult
- Imake- or Makefile and you will not have trouble with build-in pathnames !!!
-
- It's specially made for those systems, that don't have super hardware
- or that have problems with the Toolkit or MOTIF.
-
-
- XMPEG [Version 1.1]
-
- <IMG SRC="xmpeg1.gif"> <IMG SRC="xmpeg3.gif">
-
- XMPEG is a MPEG-video-player based on the MPEG-widget-implementation
- from Jim Frost and the MPEG-movie-player "mpeg_play" from the Portable
- Video Research Group at Berkeley.
-
- It just adds a few buttons and is normally getting called
- from XMPLAY, but can be used as stand-alone to include into other
- programs. Its programmed with the same methods than XMPLAY.
-
- <IMG SRC="xmpeg2.gif"> <IMG SRC="xmpeg4.gif">
-
-
- You can download XMPLAY from http://www.powerweb.de/mpeg.
