for the user to click the mouse button. How can I accomplish
this?
----------------------------------------------------------------------
Subject: -1- Is there a QuickTime movieplayer available for SGI?
Date: Fri May 3 10:23:53 PDT 1996
SGI provides QuickTime movie support as part of Movieplayer in IRIX
5.1 and later. If you can't or don't wish to upgrade, you may wish
to investigate a public domain program called Xanim which offers
QuickTime capability.
The XAnim Home Page is:
http://www.portal.com/~podlipec/home.html
and it's available for anonymous ftp from:
ftp.portal.com /pub/podlipec/xanim2703.tar.?
/pub/podlipec/cinepak.readme
/pub/podlipec/indeo.readme
If you are running IRIX 4.0.5 (any variant) or earlier, please
consider upgrading to IRIX 5.3 (if you have an R3000-based system)
or best of all, to IRIX 6.2. Both releases contain a more
full-featured set of movie tools bundled with the system.
If you upgrade to IRIX 5.3, you should download the Digital Media
Tools 5.5 product from SGI. They can be found at the following
URL:
http://www.sgi.com/Products/Evaluation/dmedia/
This is an enhanced set of digital media tools for IRIX 5.3 systems.
It provides additional support for QuickTime features and MPEG.
You do not need to download the Digital Media Tools 5.5 product
if you have IRIX 6.2.
IRIX 6.2 contains all of the enhancements in Digital Media Tools
5.5, as well as additional features and updated applications.
(Note: if you need to create content in MPEG-1 or CinePak format,
you will still need to purchase codec licenses).
------------------------------
Subject: -2- I cannot play a QuickTime movie on my Silicon Graphics
computer. How can I make it work?
Date: Thu May 2 16:33:54 PDT 1996
Here is a checklist of things to try:
- You should be using the 5.1 MR version of the OS or later. Later
versions, in particular Irix 6.2 support more QuickTime files.
- The QT movie must be "flattened". Use the Apple Movie Converter
program and choose BOTH "Make playable on non-Apple systems" and
"Make self-contained" in the Save As dialog. The file must
also be compressed with an algorithm we support. For example,
do not choose "Cinepak" or "Compact Video".
- Try changing the compression to something else, say "none" to see
if that may be the problem.
SGI has licensed the QuickTime movie file format and three
compressors from Apple. In IRIX releases 5.1 through 5.3, you can
display QuickTime movies compressed with the RLE or RPZA algorithms
(Apple Graphics and Apple Video) with the bundled SGI movieplayer.
If you have IRIX 5.3, you can download the Digital Media Tools 5.5
product. This will allow you to create and view QuickTime movies
using Cinepak compression, and it can also read QuickTime movies on
Macintosh filesystems which have not been "flattened". See the first
question in this FAQ for information on downloading the tools.
If you have IRIX 6.2, CinePak and Indeo3.2 decompressors are included.
The CinePak compressor requires a license which is included with SGI's
WebForce software product.
Prior to OS release 6.2, the SGI movie tools did not support QuickTime
movies which contain an edit list; version 6.2 and beyond supports
QuickTime movies with edit lists, and with multiple image tracks.
Typically, a QuickTime file on the Macintosh stores all of the movie
parameters and header information in the resource fork, and the
actual media (sound + video) in the data fork. To be used on a
computer which has a conventional file system (such as the Indigo),
you must first "flatten" the movie on the Macintosh before
transferring it to the Indigo. This is what the "Make playable on
non-Apple systems" option in the Apple Movie Converter does.
The Apple Movie Converter is part of the QuickTime Starter Kit, a
software package sold by Apple Computer for Macintosh systems. It is
available from retail software distributors.
------------------------------
Subject: -3- I cannot play a QuickTime movie created on a Silicon
Graphics computer on my Macintosh. How can I make it
work?
Date: Thu Feb 16 15:37:32 PST 1995
When going from an SGI to a Mac, the file must have a creator and
file type. This can be done in "ResEdit".
To move a file to the Mac...
1. Save the file in a QuickTime format. See elsewhere in this FAQ
for more details on how to create QuickTime files.
2. Move the file to a Mac (using the floptical, or ftp).
NOTE: If using ftp, make sure the mode is binary, *not* macbinary
3. Open the Mac program "ResEdit".
4. Select "Get File info..." from File menu.
5. Type "MooV" into file type field, and "TVOD" into creator field.
6. Close dialog (Choose Yes to save changes).
7. Quit "ResEdit".
It should just work from here.
------------------------------
Subject: -4- What version of QuickTime does Silicon Graphics support?
Date: Thu May 2 16:26:48 PDT 1996
Silicon Graphics does not provide support for the QuickTime
programming library, but only for the QuickTime file format.
The definition of the QuickTime file format has not changed since its
original release. Apple's enhancements have mostly been in the form
of performance improvements and new features to QuickTime which have
not changed the basic file format. So, in some sense SGI supports
every version of QuickTime. But to answer the question practically,
we do not support every features which Apple has introduced in later
releases of QuickTime, such as MIDI tracks in QuickTime files,
or QuickTime VR.
SGI is working very hard to enhance its QuickTime support over time.
In the Digital Media 5.5 tools software product for IRIX 5.3, SGI
provides support for reading and writing QuickTime movies with
Cinepak compression, as well as support for reading "non-flattened"
movies which contain separate resource and data forks.
To download the Digital Media 5.5 tools, see the first question in
this FAQ.
In IRIX 6.2, SGI also provides support for reading QuickTime files
stored with Indeo3.2 compression, and also other features of QuickTime
which were not previously recognized.
------------------------------
Subject: -5- How can I create a QuickTime file on an SGI?
Date: Thu May 2 16:28:17 PDT 1996
The answer to this question depends upon the IRIX system
release you have:
- If you are using IRIX 5.2 or earlier, you must obtain
quicktime_dev, SGI's QuickTime development option, or else
find or purchase a tool which supports QuickTime output.
SGI does not provide a method to create QuickTime movie
files in the 5.2 release of the Movie Tools. If you
obtain the Digital Media Development Option, together
with the QuickTime Development option, you can obtain a
tool which will create QuickTime files on an SGI system.
See elsewhere in this FAQ for more information on both
the Digital Media Development Option and the QuickTime
Developer's Option.
- If you are using IRIX 5.3 or later, you can use the
Movie Maker or Movie Convert applications to write a
QuickTime file.
- If you use IRIX 5.3 with any of the following:
- WebFORCE software product,
- Desktop Special Edition 1.1,
- the Digital Media 5.5 Tools
or if you use IRIX 6.2 or later, you can also use the
Movie Master/mediaconvert, dmconvert, and makemovie
utilities to create the QuickTime file. You can also
record a QuickTime movie using the Capture Tool. See
the first question in this FAQ for information on obtaining
the Digital Media 5.5 tools, or IRIX 6.2.
- If you use IRIX 6.2, note that the QuickTime Development
option has been incorporated into the Digital Media
Development option, and is no longer needed; additionally,
it supports the features found in Digital Media Tools
5.5.
There is a commercially available tool called Image Independence
which will allow creation of both SGI and QuickTime movies
under IRIX 5.2 and later. It is a batch image converter with A
GUI and command-line versions. It can also convert movies from
one type to another, or split movies into separate frames. It
comes with over 20 image formats, is fast and flexible. It lists
for $495, and it can be purchased from Elastic Reality, Inc. at
(608) 273-6585.
------------------------------
Subject: -6- I need to play MPEG movies. Does SGI offer MPEG
support?
Date: Thu Feb 16 15:42:49 PST 1995
Again, the answer to this depends on the IRIX system release
that you have.
- In all releases of IRIX up to and including IRIX 5.3,
the SGI movieplayer does not support MPEG movies.
- If you use IRIX 5.3 with the Digital Media Tools 5.5
software product or IRIX 6.2, the SGI movieplayer
supports MPEG-1 movies.
You can also create MPEG movies using the dmconvert or
Movie Master (mediaconvert) tools. See the first question
in this FAQ for information on downloading the Digital
Media Tools 5.5 software product from SGI.
For free, you have several options which work regardless of the
IRIX release you have:
1) You can use the Berkeley mpeg_play. You can get the file
mpeg_play.Z by anonymous ftp from
ftp://sgigate.sgi.com/pub/Mosaic/mpeg_play.Z
Please use the binary transfer mode to get that file, and then
enter:
uncompress mpeg_play.Z
to get mpeg_play. You can use mpeg_play to play MPEG files specified
in Mosaic documents.
2) Another MPEG player is available via FTP. Here is its URLs:
http://www.geom.umn.edu/software/download/mpeg_play.html
ftp://geom.umn.edu/priv/daeron/src/mpeg_play-src.tar.Z
This MPEG player has Motif frame controls.
3) You might want to check out sgimpeg, a program based on
mpeg_play, with all graphics replaced with IrisGL calls. It also
features some limited frame controls. The full package, bit, also
offers conversions of any frames within the MPEG stream to
jpeg/pnm/rgb and other formats. Both bit and sgimpeg are available
from
ftp://monte.svec.uh.edu/pub/bit/
via anonymous ftp.
[ Editors note: at the time of latest revision, sgimpeg was not
available at this Internet location. ]
4) Here is yet another MPEG player from Greg Ward
(greg@pet.mni.mcgill.ca):
I have also written a GL-specific MPEG player -- same general idea as
sgimpeg, but it has a cruder user interface (all keyboard) and a lot
more features (memory or disk buffering, pixel doubling/tripling/
whatever, pause, single step forward or backward).
It's available by anonymous ftp from yorick.mni.mcgill.ca, in
/pub/mpeg.
------------------------------
Subject: -7- I created a movie with Capture, but now I can't edit it
with Movie Maker or play it with Movie Player.
Date: Mon Mar 25 10:04:18 PST 1996
Check to see that you are using compatible versions of the tools.
Odds are that you created the movie with Capture (an application in
IRIX 5.1 and later), but are trying to use the tools from an IRIX
4.0.5 to view and manipulate them.
The IRIX 5.x and 6,x versions of the movie tools can read files
created by the 4.0.5 tools, but the reverse is not true.
Also, in order to edit a movie, be sure to check that you have write
permission to the file.
------------------------------
Subject: -8- How can I write a program to create, edit, convert, or
play movies? Where can I get a copy of the SGI Movie
Library?
Date: Thu May 2 16:33:54 PDT 1996
The Digital Media Development Option contains the Video,
Audio, Audio File, MIDI, CD, DAT, Movie, and Compression
Libraries. It allows you to perform tasks like these
inside your application:
- perform audio, video, MIDI I/O on SGI machines (including
programming the IndyCam)
- convert audio/video data between different formats
(this includes software and hardware
compression/decompression for audio and video)
- read/write digital media file formats (SGI movie,
QuickTime, AIFF/AIFF-C sound files)
- read/write DAT audio tapes using SGI SCSI DAT drive, read
CD audio disks using SGI SCSI CD drive.
The part number for the Digital Media Development Option is
SC4-DMDEV-2.0. For releases prior to IRIX 6.2, if you would
like to develop applications which manipulate QuickTime files,
you must also order the companion product, QuickTime 1.0 Compressor
Library, part number SC4-QTCL-1.0. The Digital Media Development
Option requires IRIX 5.2 or later (both part numbers above are
for the IRIX 5.2 versions).
In order to use the Digital Media Development Option, you
also need to have IDO 5.2. This is the basic IRIS
developer option, including compilers, basic C library
headers, graphics libraries, etc.
In the United States, you can order these products by
calling Silicon Graphics toll-free at 1-800-800-SGI1
(1-800-800-7441). If you live in a country other than the
United States, contact your nearest Silicon Graphics
office, or call one of these regional telephone numbers:
Europe (41) 22-798.75.25 (Geneva, CH)
North Pacific (81) 3-5420.71.10
South Pacific (61) 2-879.95.00
Latin America 1(415) 390.46.37
Canada 1(416) 625-4747
Starting with IRIX 5.3, the Digital Media Development
Environment has been included as a standard piece of IDO,
and you no longer need to order it separately. However,
the QuickTime 1.0 Compressor Library remains a separate
product in IRIX 5.3.
Starting with WebForce 1.1 (and including IRIX 6.2), the
QuickTime codecs have been moved into the CL, so the
QuickTime 1.0 Compressor Library option is no longer needed.
------------------------------
Subject: -9- I can't use images exported with Moviemaker in any of my
applications. What image format does Moviemaker use?
Date: Thu May 2 16:33:54 PDT 1996
In IRIX 5.2 and earlier, Moviemaker exports images using the
ImageVision FIT file format. This library is supported by the
SGI ImageVision Library and its assorted tools.
To convert FIT files to another file format, such as SGI rgb or TIFF,
use the imgcopy(1) program, part of the ImageVision Tools (imgtools)
product. The ImageVision Tools are bundled with the basic IRIX
distribution.
The following shell script will convert a batch of image files to SGI
format, using imgcopy:
#----------------------- cut here ---------------------------
#!/bin/csh
#
# iv2sgi - convert a batch of imagevision-supported files to SGI
# .rgb format using imgcopy
#
# usage: iv2sgi <filenames>
#
foreach image ($argv)
imgcopy -fSGI $image $image.rgb
end
#----------------------- cut here ---------------------------
Moviemaker 2.1, which is available in the IRIX 5.3 release,
supports image export in SGI and TIFF, as well as FIT formats.
NOTE: the IRIX 5.3 version of Moviemaker contains a bug which
prevents it from exporting images to TIFF format. Exported images
will look all black or all white. If this is important to you,
you can download the Digital Media Tools 5.5 software product,
which contains a version of Moviemaker which corrects the bug.
See the first question in this FAQ for details on downloading
the Digital Media Tools 5.5 software product.
If you have IRIX 5.3 or later, you can also use Movie Convert to
extract image frames from movie files. Moviemaster converts between
movies and images. 32 different image formats are currently
supported. All sgi movie formats are supported. Moviemaster can
extract frames from a movie, build a movie from frames, or image
convert from one format to another.
In IRIX 6.2, moviemaker allows you to choose an image file format
to output to (TIFF, RGB, etc); choose "Collection of Images" from the
pop-up menu in the dialog box, and then choose the appropriate format
from the pop-up menu in the Image Settings dialog.
------------------------------
Subject: -10- Can anyone provide details on the SGI movie format?
Date: Thu May 2 16:33:54 PDT 1996
The contents of the SGI movie file format are not documented. To
create and manipulate SGI movie files in your own application, we
recommend that you use the SGI Movie Library, part of the Digital
Media Development environment. This will not only save you work in
your application, but will ensure that your program remains
compatible with any revisions SGI makes to its movie file format.
If you need to manipulate movie files for cross-platform purposes, we
recommend that you obtain the QuickTime Developer's Option to create
QuickTime movies which can be used cross-platform. Additionally,
if you have the WebFORCE software product, or Digital Media Tools 5.5
software product for IRIX 5.3, you can create MPEG movies which can
be used cross-platform.
See elsewhere in this FAQ for more information on both the Digital
Media Development Environment and the QuickTime Developer's Option.
------------------------------
Subject: -11- Can anyone provide details on the QuickTime movie
format?
Date: 20 May 1994 00:00:01 EST
For more details on the Apple implementation of QuickTime and its
file format, see "Inside Macintosh: QuickTime" (ISBN 0-201-62201-7)
and "Inside Macintosh: QuickTime Components", both by Apple Computer
and published by Addison-Wesley. The former book contains a detailed
description of the QuickTime file format.
------------------------------
Subject: -12- How can I convert from SGI movie format to MPEG?
Date: Fri May 3 11:12:41 PDT 1996
- If you are using IRIX 5.3 with the Digital Media Tools 5.5
software product, or IRIX 6.2, you can use the Movie Master
or dmconvert utilities to create MPEG movies. See the first
question in this FAQ for information on downloading the
Digital Media Tools 5.5 software product from SGI.
- If you are using IRIX 5.3 or earlier, SGI provides no bundled
tools to convert SGI movies to MPEG.
There is a publically available program which can convert SGI
movie files to MPEG. It was developed by Andreas Paul
<paula@informatik.tu-muenchen.de>. It can be obtained from:
ftp://ftp.rus.uni-stuttgart.de/pub/systems/sgi/animation/mv2mpeg_final.tar.gz
It is for IRIX 5.x systems, and supports all versions of the SGI
movie file format.
If you are using IRIX 4.0.x, then get mov2mpeg from
ftp://ftp.gvu.gatech.edu/pub/people/kooper/mov2mpeg.tar.gz
Finally, another way to convert to MPEG is to export all of
the images and audio track from the SGI movie file by using
moviemaker or makemovie, and feed the result (a sequence of
still frames) into one of the public domain MPEG encoders
available on the net.
There is yet another freely available tool, mv2mpeg, for creating
MPEG files. Here is a quote from its README file:
mv2mpeg is a tool to convert a SGI-movie-file into a mpeg-movie.
It consists of a shell-script ('mv2mpeg') and two binaries:
mpeg_encode
mv2frames
mpeg_encode has been compiled with the '-mips2' switch, so if
you are using a R3000 machine get the mpeg_encode package and
compile it yourself. (shouldn't be much of a problem)
It can be found at:
qiclab.scn.rain.com:/pub/graphics/mpeg_encode-1.2.tar.Z
liasun3.epfl.ch:/pub/graphics/mpeg/mpeg_encode-1.2.tar.gz
If you don't find it there use 'archie' to locate the nearest
site that has it.
Regardless of IRIX software release, there is at least one
commercial product which can create MPEG files, called MpegExpert:
MpegExpert is the highest performance and most featured MPEG
playback solution for SGI platforms. It plays compressed MPEG-1
audio, video or system level multiplexed audio+video bitstreams in
realtime with stereo CD quality sound. With the integrated
CAPTURE_TOOL it lets the user cut and save pictures or sequences
from an MPEG source, allowing a simple form of editing. And with
the CD_TOOL user can play Video_CD and CD-I digital movies from a
CDROM player. Its specially designed data input architecture
enables smooth MPEG playback from video servers over networks.
MpegExpert can be integrated into other applications or it can be
used interactively through its motif based user interface.
MpegExpert software, documentation, and demo version are available
on line via anonymous ftp from ftp.portal.com:/pub/apvision or
ftp.netcom.com:/pub/ap/apvision. Any further inquiry if required,
can be sent to apvision@netcom.com
For more information on MPEG, and a list of places where you can
obtain MPEG encoder software, consult the MPEG Frequently Asked
Questions document. You can FTP it from
ftp://ftp.cs.tu-berlin.de/pub/msdos/dos/graphics/mpegfa11.zip
ftp://ftp.cs.tu-berlin.de/pub/msdos/dos/graphics/mpegfa20.zip
ftp://ftp.cs.tu-berlin.de/pub/msdos/dos/graphics/mpegfa30.zip
ftp://ftp.cs.tu-berlin.de/pub/msdos/dos/graphics/mpegfa31.zip
These documents are versions 1.1, 2.0, 3.0, and 3.1 of the MPEG FAQ
document.
------------------------------
Subject: -13- How can I convert from Microsoft AVI movie format to SGI
movie format?
Date: Mon Mar 25 10:04:18 PST 1996
Starting with IRIX release 6.2, we can read Microsoft AVI files
compressed with CinePak or Indeo3.2. (We do not have the rights
to CRAM or ULTI, which are Microsoft proprietary algorithms.) All
of our tools support reading the supported AVI files, and writing
them out to other formats.
------------------------------
Subject: -14- Is there a way to bring up a movie (using movieplayer)
within Showcase using a button click...and having it
place itself automatically in a certain location and
start?
Date: 20 May 1994 00:00:01 EST
Not that I know of. When we want to play a movie, we usually
hyperscript the object to run a script, and in the script we place
the movie where we want to. Here is an example of the script. Call
it with the movie name as an argument.
/usr/sbin/movieplayer -fNv -S$X1,$Y1,360,243 -l 1 -z $ZOOM $1
Define your zoom factor ($ZOOM) and position ( X1 Y1 ) in front of
this.
------------------------------
Subject: -15- I am using Mosaic. When I try to view a movie,
movieplayer starts, but then shows a message: no movie.
How can I make it work?
Date: 20 May 1994 00:00:01 EST
Check the following:
- Is your system running IRIX 4.0.5? The movieplayer in IRIX 4.0.5
does not support QuickTime movies. You will need to upgrade to
IRIX 5.2 in order to receive QuickTime support in movieplayer.
- Check to see that the movie file was copied over completely by
Mosaic. Sometimes Mosaic will fail to transfer the file completely
if the network load is very high.
- Finally, the following information submitted by Dave Babcock
(daveb@merlin.mti.sgi.com) may prove helpful:
xmosaic includes the capability to automatically play SGI movie files
referenced by a html document. Unfortunately, there is a "bug" which
keeps it from actually working.
Fortunately, there is an easy fix. Just edit the
/usr/local/lib/mosaic/mailcap file and change the following line:
video/x-sgi-movie; movieplayer -l 1 %s; compose=moviemaker %s; \
to be:
video/x-sgi-movie; movieplayer -f -l 1 %s; compose=moviemaker %s; \
that is just add the -f.
For those who care, the problem is: mosaic copies the movie file to a
local temp file; spawns movieplayer passing it the name of the temp
file; when it sees movieplayer "terminate" mosaic nicely deletes the
temp file. But by default movieplayer runs in background mode which
mosaic interprets as it being done and deletes the temp file just
before the background task trys to open the temp file. The symptom
is that you get the error message:
Could not open: /usr/tmp/gaaa000-0.mv: No such file or directory
could not open movie file
and nothing happens.

Read the misc FAQ for information about the FAQs themselves. Each FAQ is
posted to comp.sys.sgi.misc and to the news.answers and comp.answers
newsgroups (whose purpose is to store FAQs) twice per month. If you
can't find one of the FAQs with your news program, you can get it from
ftp://viz.tamu.edu/pub/sgi/faq/
ftp://rtfm.mit.edu/pub/usenet/news.answers/sgi/faq/
(rtfm.mit.edu is home to many other FAQs and informational documents,
and is a good place to look if you can't find an answer here.) The FAQs
are on the World Wide Web at
http://www-viz.tamu.edu/~sgi-faq/
If you can't use FTP or WWW, send mail to mail-server@rtfm.mit.edu with
the word 'help' on a line by itself in the text, and it will send you a
document describing how to get files from rtfm.mit.edu by mail. Send the
command 'send usenet/news.answers/sgi/faq/misc' to get the SGI misc FAQ,
and similarly for the other FAQs. Send the command 'send
usenet/news.answers/internet-services/access-via-email' to get the
"Accessing the Internet by E-Mail FAQ".
You may distribute the SGI FAQs freely and we encourage you to do so.
However, you must keep them intact, including headers and this notice,
and you must not charge for or profit from them. Contact us for other
arrangements. We can't be responsible for copies of the SGI FAQs at
sites which we do not control, and copies published on paper or CD-ROM
are certain to be out of date. The contents are accurate as far as we
know, but the usual disclaimers apply. Send additions and changes to
sgi-faq@viz.tamu.edu.

Subject: -1- How can I quickly find the information I want in the SGI
FAQs?
Date: 11 Feb 1995 00:00:01 EST
- The FAQs follow the RFC1153 recommendations for message digests and
thus can be viewed easily with newsreaders that understand message
digests.
- Each question has a Subject: line, so you can easily step through
the answers with rn's ^G command.
- Each question is marked with a "dash number dash" so that you can
find any answer with a simple search pattern.
- Questions marked with a '+' in the subject line are new this
posting; those marked with a '!' have significant new content since
the last posting. Similarly, '+' and '!' in the left margin mark
added or changed text. Questions marked with a '-' in the subject
line will be removed in the next edition or so unless someone
convinces us otherwise.
- Don't forget about text searching! There's an excellent chance the
information you want is in the FAQs, but not obvious from the table
of contents. Every file viewer, editor and WWW browser has a way of
finding arbitrary text in a file.
------------------------------
Subject: -2- What about the SGI FAQs and the World Wide Web?
Date: 04 May 1996 00:00:01 EST
The SGI FAQs are on the World Wide Web in hypertext form at
http://www-viz.tamu.edu/~sgi-faq/. The hypertext version (as well as
the plain text) may be FTPed from ftp://viz.tamu.edu/pub/sgi/faq/ for
offline reading. You can also get the FAQ source from the same place
and build the hypertext yourself.
There are several archives of FAQs from news.answers converted to
hypertext, including the SGI FAQs, listed at
http://www.jazzie.com/ii/internet/faqs.html, and some mirrors of
just the SGI FAQs:
http://reality.sgi.com/employees/jm/sgi-faq.html/
http://www.sgi.com/Archive/FAQs/ (and at www.sgi.com's mirrors)
Anyone is welcome to set up their own mirror, public or not. Please
note that the SGI FAQ group does not administer any of these sites, so
we can't guarantee that any of them are complete or up-to-date.
You can read the hypertext SGI FAQs with any WWW browser, e.g. Mosaic
(which you can get from ftp://ftp.ncsa.uiuc.edu/Web/Mosaic/), Netscape
(ftp://ftp.netscape.com/netscape/unix/ for the generic version or
http://www.sgi.com/Products/Evaluation/netscape/page1.html for the
custom SGI version) or, for text terminals, Lynx
(ftp://ftp2.cc.ukans.edu/pub/WWW/lynx/). A Mosaic binary for IRIX
4.0.x, including WAIS support, is in IBD's SGI collection; see below
under "WWW pages".
Some types of references in the SGI FAQs are formatted so that our
hypertext conversion software (and perhaps others') recognizes them
and turns them into links:
- References to Internet services are written as URLs.
('protocol://site/path/file'). If you're reading the SGI FAQs as
plain text, you can paste URLs into your browser. If you're not
using a WWW browser and you want to access an FTP URL
('ftp://site/path/file'), just do 'ftp site', 'cd /path' and 'get
file' as usual to get a file. References to directories end with
slashes so you know what you're getting into. Some FTP servers are
incompatible with some WWW browsers; use 'ftp' or another browser.
At this writing viz.tamu.edu does not accept FTP connections from
Netscape; use 'ftp', Mosaic or lynx.
- Manpages are written 'foo(1)' in the traditional Unix manner and
linked to the "uman" database of IRIX manpages at
http://reality.sgi.com/cgi-bin/uman.
- Internet RFCs ("Requests for Comment") are written 'RFC####' and
linked to the collection of RFCs at http://ds.internic.net/rfc/.
------------------------------
Subject: -3- With what version(s) of IRIX do the SGI FAQs deal?
Date: 13 Jul 1996 00:00:01 EST
Unless otherwise specified, the FAQs discuss IRIX 5.2 or later. A few
entries deal with IRIX 3.x and 4.x, and they should all say so.
Versions of IRIX 5 before 5.2 are rarely discussed because everyone
should have upgraded by now. IRIX 6.x is not covered as well as it
should be, but since 6.0.1 is based on 5.2 and 6.1 is based on 5.3,
discussions of problems with 5.2 and 5.3 are often relevant to 6.0.1
and 6.1 respectively.
------------------------------
Subject: -4- What about material which doesn't fit in the FAQs?
Date: 13 Feb 1995 00:00:01 EST
Entries in the FAQs should be relatively short and genuinely
"frequently asked". Some material which is of less general interest
or which is too long is archived at ftp://viz.tamu.edu/pub/sgi/. If
information you're looking for isn't in the FAQs, look there. The
FAQs may direct you there as well. You can submit material to that
archive just as you can an FAQ: mail it to sgi-faq@viz.tamu.edu, or
put it in ftp://viz.tamu.edu/incoming/ and let us know by mail. If
you have a lot, perhaps it should be its own FAQ. If you like we can
post your SGI-related FAQ for you.
------------------------------
Subject: -5- What are the comp.sys.sgi.* newsgroups?
Date: 04 May 1996 00:00:01 EST
The active SGI newsgroups are
comp.sys.sgi.announce Announcements for the SGI community.
(Moderated)
comp.sys.sgi.admin System administration on Silicon
Graphics' Irises.
