       This release note describes patch SG0001694 to IRIX 6.3.

       Patch SG0001694 replaces patches SG0001779 and SG0001905.

       This patch contains bug fixes for O2 systems with the R5000
       and R10000 processor.  The software cannot be installed on
       other configurations.


       1.2  _S_u_p_p_o_r_t_e_d__S_o_f_t_w_a_r_e__P_l_a_t_f_o_r_m_s

       This patch contains bug fixes for IRIX 6.3 (version
       1253422538) systems in the following areas: the Digital
       Media Execution environment (version 1253422532),
       configuration files for the Desktop (version 1253422520),
       and configuration files for the Media Warehouse (version
       1253326420).

       You must also have patch SG0001795 (O2 OpenGL) and patch
       SG0001976 (O2 Kernel Graphics Driver), or replacement
       versions of these two patches, installed along with this
       patch (SG0001694).

       The software cannot be installed on other configurations.

       This patch contains fixes for the following bugs in IRIX
       6.3.  Bug numbers from Silicon Graphics bug tracking system
       are included for reference.

          +o Plug-in effects library was unnecessarily maintaining a
            ICE context.  (Bug #481072)

          +o Audio on movies with scaled edits was bad.  (Bug
            #332051)

          +o AVI Movies (headers and audio) are sometimes created
            wrong. (Bug #456073, #487440)

          +o ICE now can encode/decode movies with a height of 486
            pixels.  (Bug #483792)

          +o ICE JPEG color space conversion code produces CCR601
            (nominal) values. (Bug #467089)













                                  - 2 -



          +o The SGI movie library mishandles "empty edits" and
            gaps.  (Bug #447642)

          +o ICE JPEG microcode decodes some images incorrectly.
            (Bug #479932)

          +o fxbuilder sometimes doesn't handle movie aspect ratios
            properly.  (Bug #425295)

          +o The SGI movie library playback engine now supports
            playback to video out. (Bug #396874)

          +o There are several OpenGL tuned Premiere transition and
            filter plug-ins provided in this patch.  (no bug #)

          +o The SGI movie library now supports the QuickTime
            MJPEG-A format.  New versions of dmplay, dmconvert, and
            mediaconvert which support MJPEG-A are provided in this
            patch.  (Bug #475569)

          +o Miscellaneous Digital Media bug fixes in support of
            Adobe Premiere.  (Bug #450878)

          +o Media Warehouse and the Desktop Previewer component now
            recognize PhotoCD, SoftImage, Alias/Wavefront, and AVI
            files.  (Bug #453118)

          +o Added mvOpenFD to list of exported functions in
            moviefile.exports. (Bug #464499, originally fixed in
            patch SG0001905)

          +o There is a race condition in libmoviefile.so that can
            cause movie playback in mediaplayer (movieplayer) or
            other apps to stop, hang, or crash. Often, in
            mediaplayer a dialog displaying "Play Error: Nothing
            Rendered" appears right before the hang or crash.  This
            incident has also been reported in SGI Bugs #445888,
            #446330, and #455702 as well as customer case number
            #717777.  (Bug #441197, originally fixed in patch
            SG0001779)

       Because you want to install only the patches for problems
       you have encountered, patch software is not installed by
       default.  After reading the descriptions of the bugs fixed
       in this patch (see Section 1.3), determine the patches that
       meet your specific needs.

       If, after reading Sections 1.1 and 1.2 of these release
       notes, you are unsure whether your hardware and software
       meet the requirements for installing a particular patch, run
       _i_n_s_t.  The _i_n_s_t program does not allow you to install
       patches that are incompatible with your hardware or
       software.

       Patch software is installed like any other Silicon Graphics
       software product.  Follow the instructions in your _S_o_f_t_w_a_r_e
       _I_n_s_t_a_l_l_a_t_i_o_n _A_d_m_i_n_i_s_t_r_a_t_o_r'_s _G_u_i_d_e to bring up the miniroot
       form of the software installation tools.

       Follow these steps to select a patch for installation:

         1.  At the Inst> prompt, type

             iiiinnnnssssttttaaaallllllll ppppaaaattttcccchhhhSSSSGGGG_x_x_x_x_x_x_x

             where _x_x_x_x_x_x_x is the patch number.

         2.  Initiate the installation sequence. Type

             IIIInnnnsssstttt>>>> ggggoooo

         3.  You may find that two patches have been marked as
             incompatible.  (The installation tools reject an
             installation request if an incompatibility is
             detected.)  If this occurs, you must deselect one of
             the patches.

             where _x_x_x_x_x_x_x is the patch number.

         4.  After completing the installation process, exit the
             _i_n_s_t program by typing

             IIIInnnnsssstttt>>>> qqqquuuuiiiitttt

       To remove a patch, use the _v_e_r_s_i_o_n_s _r_e_m_o_v_e command as you
       would for any other software subsystem.  The removal process
       reinstates the original version of software unless you have
       specifically removed the patch history from your system.

       where _x_x_x_x_x_x_x is the patch number.

       To keep a patch but increase your disk space, use the
       _v_e_r_s_i_o_n_s _r_e_m_o_v_e_h_i_s_t command to remove the patch history.
