_d_m_p_l_a_y plays back a movie file which contains a JPEG-compressed video
track.
By default, _d_m_p_l_a_y shows the video output in a window on your monitor as
well as to video output devices connected to _m_v_p (built-in on O2
systems), _i_m_p_a_c_t (Impact or Octane Video, as well as the Impact or Octane
Compression options), _e_v_1 (Indy Video, Indigo2 Video, and Galileo Video,
for other systems). A hardware decompressor (_i_c_e for O2 systems, _i_m_p_a_c_t
for Impact and Octane Compression, _c_o_s_m_o for others) is used to decode
the image track by default.
_d_m_p_l_a_y can optionally be instructed to display the image track only in a
graphics window, or (on O2 systems) only to video. It can also
decompress the track using software JPEG decompression (to a graphics
window) if the hardware decompressor is not available.
The O2 version of _d_m_p_l_a_y can handle movies in either the old SGI format
or the new QuickTime format. Other versions may only be able to play back
movies in the SGI format.
OOOOPPPPTTTTIIIIOOOONNNNSSSS
----hhhh help
With this flag, _d_m_p_l_a_y prints a detailed description of the command
line options. It is tailored to show only what are actually
available on your system for parameters that are system-dependent,
such as, the video device, the decompressor engine, etc.
----vvvv verbose
If the verbose option is specified, information is printed about the
movie and the play back parameters. Multiple ----vvvv options may be
specified to increase the amount of information printed.

Specify video port: display the image track in a ggggrrrraaaapppphhhhiiiiccccssss window
only, or to vvvviiiiddddeeeeoooo outputs connected to the video ddddeeeevvvviiiicccceeee, which must
be mmmmvvvvpppp for O2 systems, iiiimmmmppppaaaacccctttt for Impact and Octane Video, and eeeevvvv1111
for others. The hardware decompression eeeennnnggggiiiinnnneeee must be iiiicccceeee for O2
systems, iiiimmmmppppaaaacccctttt for Impact and Octane Compression, and ccccoooossssmmmmoooo for
others. Software decompression engine, specified by sssswwww, is
available on all systems.

----pppp aaaauuuuddddiiiioooo
Enable audio port: play back audio track if present in file. This is
the default.
Audio playback is supressed if video is not displayed in real-time,
such as when software decompression engine is used, or when ggggrrrraaaapppphhhhiiiiccccssss
display is chosen for systems using ccccoooossssmmmmoooo engine. O2 systems can
play synchronized audio with video as long as iiiicccceeee is used as the
decompression engine, regardless of whether ggggrrrraaaapppphhhhiiiiccccssss or vvvviiiiddddeeeeoooo is
chosen for display.
----gggg no graphics display
For O2 systems only. This option supresses graphics window display.
If vvvviiiiddddeeeeoooo is the display port (either specified or selected by
default), this option causes the display to be sent only to video
outputs. If ggggrrrraaaapppphhhhiiiiccccssss is the display port, this option supresses the
showing of the movie's video track entirely, resulted in an audio-
only playback.
----ffff force sample rate
Forces dmplay to change the audio hardware's sample rate regardless
of whether another application is running.
----EEEE [aaaauuuuttttoooo | kkkkeeeeyyyy]
If aaaauuuuttttoooo, _d_m_p_l_a_y closes the window and exits as soon as the playback
completes. If kkkkeeeeyyyy, _d_m_p_l_a_y waits for user input (mouse click) after
playback. aaaauuuuttttoooo is the default.
----LLLL [rrrreeeeppppeeeeaaaatttt | nnnnoooonnnneeee or ssssppppiiiinnnn1111 | ssssppppiiiinnnn2222]
Loop mode: if not specified from the command-line, the loop mode
specified in the movie file header serves as the default. Swing-mode
looping is not supported. If ssssppppiiiinnnn1111 then repeat last field at end of
playback. If ssssppppiiiinnnn2222 then repeat last frame - 2 fields - at the end.
----zzzz nnnn////dddd
Zoom output to n/d. The zoom may be either greater or less than
one. Not all zoom factors are supported; dmplay will use whatever
value is closest to the one specified. The zoom factor may be
specified as a floating point value or a rational number, e.g. .25
is equivalent to 1/4.

The following playback modes, among others, are supported.
Play back using default hardware decompression engine to a window and
video outputs, with synchronized audio playback if the movie contains an
audio track:
