_m_e_d_i_a_p_l_a_y_e_r, also known as _m_o_v_i_e_p_l_a_y_e_r for backwards compatibility, is a
player application for SGI, QuickTime, AVI and MPEG-1 movie files, as
well as Audio files supported by the SGI audiofile library (eg, AIFF,
AIFC, WAVE, MPEG1-audio, Sun .snd/Next .au, etc.).
_m_e_d_i_a_p_l_a_y_e_r can be used as a stand-alone application with a graphic user
interface for interactive control of the playback. It can also be used as
a command line utility for launching playback from within other
applications, such as IRIS Showcase or your favorite World Wide Web
browser, or from your own shell scripts.
CCCCOOOOMMMMMMMMAAAANNNNDDDD LLLLIIIINNNNEEEE AAAARRRRGGGGUUUUMMMMEEEENNNNTTTTSSSS AAAANNNNDDDD FFFFLLLLAAAAGGGGSSSS
----nnnnooooffffoooorrrrkkkk
Specifies that _m_e_d_i_a_p_l_a_y_e_r should run in the foreground, when
invoked from the shell. This option is consistent with the rest of
the bundled media tools. The deprecated option -f is equivalent and
is provided for backward compatibility.
----NNNN Provide no window borders for the visual portion of the playback.
Even though the window has no border, you can still use the standard
window manager commands to move and close the window.
----vvvv Specifies view-only mode. In this mode, the menu bar and transport
controls are hidden, leaving only the display of the media inside
the window (if needed). By using the pop-up menu on button 3
(usually the right button), the user may show these at a later time.
This pop-up menu will also enable the user to save the file under a
different name, or quit the application.
----zzzz zzzzoooooooommmmffffaaaaccccttttoooorrrr
Specifies zoom factor for the visual display of the media. The size
of the display will be scaled up or down by the specified amount in
both the X and Y dimensions. The zoom factor can be expressed in a
floating point value from 0.1 to 4.0. (Not applicable to audio
files.)
----llll llllooooooooppppccccoooouuuunnnntttt
Play the movie the specified number of times, then exit. A value of
0 means to loop forever. This option automatically places the
player into view-only mode.
----WWWW sssswwwwiiiinnnnggggccccoooouuuunnnntttt
Play the movie forward and reverse the specified number of times,
then exit. A value of 0 means to alternately play the media
PPPPaaaaggggeeee 1111
mmmmoooovvvviiiieeeeppppllllaaaayyyyeeeerrrr((((1111)))) mmmmoooovvvviiiieeeeppppllllaaaayyyyeeeerrrr((((1111))))
forwards then backwards forever. A swing count value of 2 will play
the media forward once, backward once, and then quit the program.
This option automatically places the player into view-only mode.
----bbbb bbbbaaaannnnddddwwwwiiiiddddtttthhhh
Play the movie with the given audio bandwidth, which may be "f"
(full), "h" (half), or "q" (quarter). Lower bandwidths require less
computation and may result in better video quality. This option is
currently used for MPEG-1 movies only. The default is half
bandwidth.
RRRREEEESSSSOOOOUUUURRRRCCCCEEEESSSS
If you want private customizations, create or edit the file to
$HOME/.desktop-`hostname`/MediaPlayer to add resources with your desired
values (eg, "audioBandwidth: full", etc).

_m_e_d_i_a_p_l_a_y_e_r is able to play QuickTime movies for which an available
decompressor has been installed. Such decompressors may include one
of the following:
_C_i_n_e_p_a_k
_A_p_p_l_e _A_n_i_m_a_t_i_o_n (_R_L_E _e_n_c_o_d_i_n_g)
_A_p_p_l_e _V_i_d_e_o (_R_P_Z_A _e_n_c_o_d_i_n_g)
_A_p_p_l_e _C_o_m_p_a_c_t _V_i_d_e_o
_A_p_p_l_e _P_h_o_t_o (_n_o_n-_i_n_t_e_r_l_a_c_e_d _J_P_E_G) _N_o_t_e *
_S_t_a_n_d_a_r_d _Q_u_i_c_k_T_i_m_e _M_o_t_i_o_n _J_P_E_G_A (_M_J_P_E_G_A)
_I_n_t_e_l _I_n_d_e_o _V_i_d_e_o (_R_3._2)
_D_V/_D_V_C_P_r_o _d_a_t_a
``_R_a_w'' (_u_n_c_o_m_p_r_e_s_s_e_d)
Note *: JPEG decompression is done using hardware on O2 machines if
the image size is a multiple of 8 high and 8 wide.
In addition, _m_e_d_i_a_p_l_a_y_e_r can play movies in the QuickTime format
that have been compressed with the Cosmo Compress board, using
hardware playback support on Indy's with Cosmo Compress boards, or
on O2 systems using its built in hardware support. This interlaced
JPEG encoding will not be playable on other platforms supporting
QuickTime; for cross-platform use, these movies should be converted
to either Motion JPEG-A or Photo-JPEG, or one of the other standard
compression schemes (uncompressed, CinePak, etc).
_m_e_d_i_a_p_l_a_y_e_r does not require that the QuickTime file be flattened
before it can be played. However, the resource fork must exist in
its proper location. If the file was copied to the IRIX file system
using the IRIX Interactive Desktop, the appropriate resource files
should be in place. (But note that rcp or cp will _n_o_t automatically
copy the resource fork file!) However, it should be noted that, in
many cases, playback performance as well as file size will be
improved on flattened files. Therefore, before publishing movies, it
PPPPaaaaggggeeee 2222
mmmmoooovvvviiiieeeeppppllllaaaayyyyeeeerrrr((((1111)))) mmmmoooovvvviiiieeeeppppllllaaaayyyyeeeerrrr((((1111))))
is generally advisable to flatten them. _m_o_v_i_e_m_a_k_e_r(_1)'s ``Export
As'' command, as well as _m_e_d_i_a_c_o_n_v_e_r_t and _d_m_c_o_n_v_e_r_t can flatten
QuickTime movies.
_m_e_d_i_a_p_l_a_y_e_r now also supports playing QuickTime movies with
compressed audio, for the audio compression schemes IMA4:1 (common
on some sites on the Internet), and DV-Audio (normally only seen in
DV/DVCPro QuickTime files).
SSSSGGGGIIII MMMMoooovvvviiiieeee
When the Cosmo Compress hardware is present, _m_e_d_i_a_p_l_a_y_e_r will play
interlaced JPEG files created by or for use with Cosmo Compress.
These movies will also play using the built in hardware support in
the O2 platform.

_m_e_d_i_a_p_l_a_y_e_r supports playback of MPEG-1 movies (video bitstreams, or
systems bitstreams with a video track). Unlike SGI and QuickTime
movies, MPEG-1 movies generally do not include index table
information which facilitates track length determination and frame-
accurate random access.
AAAAVVVVIIII MMMMoooovvvviiiieeee
_m_e_d_i_a_p_l_a_y_e_r is able to play AVI movies that use these compression
schemes: JPEG, Apple Compact Video, Indeo R3.2 or none
(uncompressed).
DDDDVVVV////DDDDVVVVCCCCPPPPrrrroooo DDDDIIIIFFFF MMMMoooovvvviiiieeeessss
_m_e_d_i_a_p_l_a_y_e_r is able to play DV or DVCPro DIF movies (streams). This
is an industry-standard raw file format commonly used to store data
copied from DVC format camcorders and VCRs. It can contain image and
audio data.
AAAAuuuuddddiiiioooo FFFFiiiilllleeeessss
_m_e_d_i_a_p_l_a_y_e_r supports all file formats supported by the SGI audio
file library, including AIFF-C, AIFF, NeXT/Sun format, WAVE, BICSF,
MPEG1 bitsream, SoundDesigner2, and others. Please see
aaaaffffIIIInnnniiiittttFFFFiiiilllleeeeFFFFoooorrrrmmmmaaaatttt(3dm) for more details.
KKKKEEEEYYYYBBBBOOOOAAAARRRRDDDD CCCCOOOOMMMMMMMMAAAANNNNDDDDSSSS
_m_e_d_i_a_p_l_a_y_e_r and _m_o_v_i_e_m_a_k_e_r support left-arrow and right-arrow keyboard
equivalents for "step forward" and "step backward" when viewing a movie
file. Note that this functionality applies only to movie files, not audio
files.

When the user makes a selection using the timeline, _m_e_d_i_a_p_l_a_y_e_r will
activate the "Copy" entry on the "Edit" menu. _m_e_d_i_a_p_l_a_y_e_r supports
copying the current selection to the X-Clipboard, so that users may paste
from _m_e_d_i_a_p_l_a_y_e_r into other X-based applications, such as moviemaker,
imgworks, soundeditor, inperson, etc. When a user chooses "Copy,"
_m_e_d_i_a_p_l_a_y_e_r will advertise a number of formats of data that it makes

available to other applications to paste:
MMMMoooovvvviiiieeee DDDDaaaattttaaaa
A Movie of the current selection. (SGI or QuickTime)

An audiofile of the current selection, assuming that the current

_m_e_d_i_a_p_l_a_y_e_r supports all of the command-line options that were supported
in _m_o_v_i_e_p_l_a_y_e_r (which _m_e_d_i_a_p_l_a_y_e_r obsoletes) with one notable exception.
The command flag -S is no longer supported. Use the standard X -geometry
method instead. These should proceed the _m_e_d_i_a_p_l_a_y_e_r command-line
options.

To show a simple movie window at a specific area on the screen, without
borders or a control panel, use a command like:

To make a movie appear on the screen, play itself three times, and
disappear, use a command like:
