SOURCE:
- Choosing an Input Jack -- documents/video/lurker/ij/, src code example, from The Lurker's Guide to Video, information gold mine of what you need to know about video.
- public:
- Chaos: The Chaotic Music Generator, Version 1.0
- rsynth: Rsynth speech synthesizer ported to SGI, Version 1.0
- public/freeware1.0:
- Cspect -- real-time oscilloscope/spectrum analyzer
- mpegaudio -- mpeg encoder/decoder does LayerI&II audio
- sono -- generate a score from electroacoustic piece
- sox10, v1.0-ircam -- universal sound converter
- tracker, v4.31 -- modfile-player
- src/apps/CDio, software for Writing and Reading CDs enables one to make an SGI efs OR ISO or Audio CD
- src/exampleCode/movies/cineswipe,
allows you to record your GL or OpenGL based application's graphics
into a digital movie file (SGI, QuickTime, JPEG) without
touching the application itself. This functionality is exemplified
by a technique for substituting DSO functions in any DSO-based
application.
- src/demos/audio contains,
- amesh
and ameshC, provide C++ and
"straight C" versions of an "audio mesh" spectrum analysis of an
incoming audio signal and displays it in a real-time "waterfall"
of frequency spectrums.
- synthia, a midi
synthesizer, plays a midi sound file and simultaneously displays the
notes on a simulated keyboard.
- video, contains video demo progs including:
- specialfx, demos many of the special effects features possible
with Galileo, Indigo2 Video and IndyVideo, particularly in the areas of
chroma keying, luma keying, and transitions (also known as wipes & fades,
blends, and/or switches),
- vidpaint, captures video into memory at the 1/4 by 1/4 size
(1/8 the area of the full size of the source you are using), and then
draws the frames into a window,
- vidtmesh, captures video into memory at the 1/4 by 1/4 size,
(1/8 the area of the full size of the source you are using) and places
the frames onto a 3D triangle mesh (tmesh) grid, which you can then
manipulate in space,
- bigvideoin, simple mini app shows a zoomed up videoin window
nearly filling your display with video, and,
- trails, a specialty program, sets up a feedback loop so that
you can see trailing effects.
- src/exampleCode/audio
contains,
- DAT:
3 DAT example programs,
- ascope:
displays left channel of data coming in from an audio port,
- harmonizer:
real-time audio pitch bender example,
- midi:
example programs using libmidi.a illustrate basic use of the MIDI library,
- reverb:
simulated reverberation for real-time audio input and output<
- rock:
the indigo memorial barbeque theme song rapp, a study in random
looping of musical "melodies" and rhythms,
- somePlayback:
code to generate a bunch of oscillators, waveforms, change playback
rate, mix, change pitch, loop audio samples and send them to the speaker,
- sonic:
simple real time audio spatialization example with graphics, and,
- tablenet:
generates small series of waveforms and writes them into a 16-bit
AIFF file.
- sgi src/exampleCode/speech
speech recognition examples, IRIX 5.3 inst images, and
utilities.
- src/exampleCode/video
subtree contains,
- contcapt: a
converted OpenGL version of the VL contcapt program.
- scrollmon:
creates realtime scrolling credits or titles (graphics) for video
production,
- seqgrab:
VL sequential frame accurate capture source (Galileo/VLAN),
- simpleVideo:
library + examples to provide the video programmer with a simple
programmatic interface on top of the VL,
- vidmap:
texture mapping of video -- selection can be a live source such as
IndyCam, any other live video source, or a (SGIMF, QuickTime, or MPEG),
movie file which is then texture mapped to the polygon.
- src/haeberli subtree contains,
- movies:
sample movie files for the imgtools/expmov program,
- mpeg:
a public domain MPEG video software decoder,
- vidiot:
"video feedback" prog animates a face w/audio input,
- vidpan:
tools for controlling a Panasonic Video disc recorder,
- vidsony:
tools for controlling a SONY LVR-5000 Video disc recorder,
- vidtools:
tools for processing streams of video images.
