- MediaPlayer (invoked from the command line as _m_e_d_i_a_p_l_a_y_e_r)
- is a graphical tool that allows you to play back movie or
- sound files. Movie files can be created using MovieMaker,
- MediaConvert, _d_m_c_o_n_v_e_r_t(_1), or MediaRecorder (see below).
- Sound files may be created by the above tools, SoundEditor
- or SoundTrack (multiple track sound editor).
-
- See the man page _m_e_d_i_a_p_l_a_y_e_r(1) or MediaPlayer's on-line
- help for more information.
-
- The directory /_u_s_r/_s_h_a_r_e/_d_a_t_a/_m_o_v_i_e_s contains sample movies,
- if the subsystems dmedia_eoe.data.movies and/or
- dmedia_eoe.data.moremovies are installed. There is an SGI
- movie file, _s_o_m_e_r_s_a_u_l_t._m_o_v_i_e, and a sample QuickTime movie,
- _s_a_m_p_l_e_Q_T._m_o_v. _s_t_u_d_i_o._m_p_s is an MPEG systems stream movie.

- This section lists problems in the MediaPlayer software and
- ways to work around them.
-
- +o In order to play movies to video out on an O2, the
- video ouput signal's Output Sync must be set to
- "Internal". Failing to establish this setting will
- cause Media Player to hang. To adjust or verify the
- Output Sync setting, open _v_c_p(_1), choose Pro -> Video

-
- Output -> Signal Controls. Then from the Video Output-
- Signal panel choose "Internal" on the Output Sync
- pulldown menu.
-
- +o The "-S" command line flag is no longer supported. Use
- the standard X mechanism using "-geometry +X+Y".
-
- +o MIDI playback has some problems. If you should
- encounter problems playing a MIDI file, you may use
- _s_o_u_n_d_p_l_a_y_e_r(_1) instead.
-
- +o The current SGI movie format version number is 3.
- Movies made or edited with IRIX 5.1 or later releases
- of Movie Maker might not play or might play incorrectly
- with the IRIX 4.0.5 version of MediaPlayer However,
- the current version of MediaPlayer plays all versions
- (1, 2 and 3) of SGI movies correctly.
-
- +o MediaPlayer does not work correctly over the network.
- The user interface and images will display on the local
- machine, but the audio will play on the remote machine.
- In addition, if you are displaying MediaPlayer from an
- IRIX 6.2 or later system to an IRIX 5.3 system, you may
- need to install one of the following patches on your
- IRIX 5.3 system which fixes an OpenGL problem: number
- 450, 720, or 926.
-
- +o MediaPlayer does not support the playback of FIT image
- sequences in this release. You can work around this
- problem by using MovieMaker or dmconvert to convert
- your FIT images to a supported movie format.
-
- +o If you choose "Play Every Frame" from the "View" menu,
- audio is disabled while the movie is playing. To
- restore audio, deselect "Play Every Frame."
-
- +o For MPEG movies only: the "Copy" command will only
- provide a still image; it will not provide movie-file
- or audio-file targets of the selection.
-
- +o MediaPlayer is not able to play certain MPEG movies
- where the MPEG information starts at an offset other
- than 0. For these movies, Movie Player may hang or
- crash.
