=================================================
This release of the OS/2 Plug-in Pack for Netscape Navigator offers you:
o Native OS/2 Multimedia Plug-ins
o Support for Windows 3.1 Plug-ins
o OS/2 Multimedia MPEG support
4.0 MULTIMEDIA PLUG-INS
=================================================
The native OS/2 Multimedia Plug-ins in this package provide
support for multimedia MIME Types and file extensions such
as .MPEG, .avi, .voc, .aiff, .wav, and .midi.
The Native OS/2 Multimedia Plug-ins provide support for streaming multimedia.
This means that certain files that support streaming can be played
while they are downloaded. A Multimedia Internet Manager program is
provided to access these files and it can be started from the System setup
folder after you install the plug-ins. The Multimedia Internet Manager
stores temporary files in the [d:]\MMOS2\INETTEMP directory.
This table describes the media types supported by the OS/2
Multimedia Plug-ins:

Note 1: This media type support requires additional software. One
example is the AnpoCodec shareware package. Visit
http://www.shareware.com and search in the OS/2 section for "codec".
Note 2: This media type support requires additional software. One
example is the QuickMovie package from Practice Corporation available
at http://www.practice.xo.com.
Note 3: This media type support requires additional software. Ensure
that you have the Warp Bonus Pack or FixPack 17 installed.
Notes:
o If you prefer to use helper applications you can
remove the native OS/2 multimedia plug-ins by renaming
the following OS/2 Multimedia plug-ins DLLs in the
plug-ins subdirectory of the install directory:
NPOS2AUD.DLL - all audio formats except MIDI
NPOS2MID.DLL - MIDI audio
NPOS2VID.DLL - video
For example, rename NPOS2AUD.DLL to NPOS2AUD.SAV.
o When files are downloaded using the native OS/2
Multimedia Plug-ins, they can be retained by the
system even after you have exited Netscape Navigator.
This can cause additional disk space to be consumed.
The Multimedia Internet Manager, in the System
Settings folder, allows you to remove some or all
of these files, as well as change the directory
that contains this multimedia data.
5.0 SUPPORT FOR WINDOWS 3.1 PLUG-INS
====================================================
All versions of OS/2 Warp, OS/2 Warp Server, and OS/2
Warp Server Advanced Version 4 SMP Feature support
the use of Windows 3.1 Plug-ins. Support for Windows
3.1 Plug-ins on OS/2 Warp Version 3.0 and OS/2 Warp
Connect Version 3.0 requires installation of FixPak 26.
If you need to install FixPak 26, remove Netscape Navigator
for OS/2 from your system and re-install it. This ensures that
the OS/2 Warp system updates are made in the correct
sequence.
Some Windows 3.1 Plug-ins require specific installation
steps:
Shockwave: The Shockwave installer should be run from
WIN-OS/2 File Manager or from the Program Manager
Command line. After installation is completed, exit
Program Manager.
Sizzler: Sizzler displays a test window for an extended
period of time the first time it is used. A Timeout
message box might display. Press Retry
until the test window completes its test.
Note: If you prefer not to use the Windows 3.1 Plug-ins
support, you should rename the file NPPROXY.DLL in the
plug-ins subdirectory of the install directory to NPPROXY.SAV.
6.0 PLUG-IN APIs AND TOOLKIT
====================================================
Developers who want to develop native OS/2 Plug-ins for
the Netscape Navigator for OS/2 can use a Plug-in Toolkit
that includes header files, libraries, and sample code for
building OS/2 native plug-ins that can be downloaded.
To download the toolkit, go to the URL:
http://www.internet.ibm.com/browsers/netscape/warp
and select OS/2 Plug-in Developers Kit.
7.0 OS/2 MULTIMEDIA MPEG SUPPORT
============================================================
The new IBM MPEG support includes software MPEG video file
playback that does not require special MPEG hardware.
7.1 Software Requirements
-------------------------
OS/2 Multimedia MPEG Support requires OS/2 Warp Version 3 or
later. However, OS/2 Warp Version 3 systems also require the
OS/2 Warp Multimedia fixes that are available for this installation.
7.2 Recommended Hardware Configuration
--------------------------------------
A Pentium hardware configuration is recommended because
software MPEG is very CPU-intensive. Software MPEG can be
used on a computer with a 486 microprocessor, but the video
quality is minimal.
Software MPEG audio support is available, but performs
poorly on systems slower than a Pentium 90MHz.
Hardware MPEG audio is supported with IBM MWAVE cards or
ReelMagic cards.
MPEG hardware is used transparently, if it is available.
An updated ReelMagic driver set is provided and
installable if the hardware configuration includes the
ReelMagic drivers. These drivers should not be installed
unless the hardware exists in the machine where the
drivers are being installed. For hardware video support,
VSDOM1.INI must be installed in the \MMOS2 directory. Using
the OS/2 Multimedia MPEG Support installation, select the
MPEG card installed in the system.
A 2-speed CD-ROM is required to play CD-i or Video CD
content. This CD-ROM must support long reads. Some OS/2
CD-ROM drivers do not support the long reads that CD-i
requires. CD-i content is not readable through the file
system. Playing this content requires a dummy file named
_VIDCDI.MPG. Playback quality is very jerky for
polling CD-ROMs.
7.3 Installation
----------------
MPEG support can be selected during the installation of
the Plug-in Pack.
7.4 Backward Compatibility for MCI applications
-----------------------------------------------
A video MCD is provided for backward compatibility for
existing applications that utilize the Media Control
Interface (MCI). This means the existing media
player provided with OS/2 Multimedia can be used to
play MPEG content.
7.5 MPEG Limitations
--------------------
o MPEG-2 Transport streams with buffered play only works
with 188 byte size buffers. All others are rejected.
o Playback from content on slow CD-ROMS (less than 4X)
results in poor video playback quality.
7.6 Configurations With Existing MPEG Hardware Support
------------------------------------------------------
To configure OS/2 Multimedia MPEG Support to be used as the
default hardware MPEG device, do the following:
1. In the Multimedia Setup, on the Association page for the
existing MPEG hardware, select the MPEG data type and
remove all current extensions.
2. On the OS/2 Multimedia MPEG Support Association page,
select the MPEG data type and add the following extensions:
MPG, CDI, VBS, DAT, M1T, M2T, M2P.
7.7 About Plugins
--------------------
The About Plugins section states that you have QuickTime support.
This means that QuickTime is enabled, but QuickTime plugins
are not be supported unless a QuickTime support is installed.
Companies that provide OS/2 QuickTime support are Practice Corp.
and MainActor.
7.8 Software MPEG Performance
-------------------------------
To decrease software MPEG usage, go to the Multimedia Setup notebook
on the OpenMPEG page and change the synchronization factor to
greater than 40 or to the maximum. This slider is not proportional
in changes. Increasing the synchronization factor decreases
the video quality, but improves CPU performance so that software
MPEG is not taking the maximum out of the CPU. This synchronization
factor has no effect on hardware MPEG.
7.9 Multimedia Setup Page
-------------------------
If audio fails to play, try specifying the Software Only
mode for audio for the OpenMPEG Video device in the
Multimedia Setup object (in the System Setup folder).
This change could be necessary for systems containing
Audiovation sound cards.
7.10 Video CD/CD-i Support
--------------------------
Video CD and CD-i content is supported with the Software
Video CD icon in the Multimedia folder. Systems with MPEG
hardware such as a Thinkpad 760 can already have a Video CD
Player icon. This allows Video CD to run through the existing
MPEG device. If the Software Video CD icon is used on
systems with MPEG hardware, OS/2 Multimedia MPEG
Support attempts to play the content using hardware.
Use the Software Video CD icon if the system has been
customized with OS/2 Multimedia MPEG Support as the default
MPEG device.
7.11 Future Hardware Support
----------------------------
OS/2 Multimedia MPEG Support installs hooks for the
following hardware devices:
o Thinkpad 760CD MPEG
o Thinkpad 760ED MPEG
o Sigma Designs ReelMagic
o Sigma Designs ReelMagic Pro
o Visual Circuits ReelTime
If MPEG hardware is installed later, the VSDOM1.INI file
must be created by running the MKVSDINI.CMD file in the
\MMOS2 directory. For new MPEG hardware not in the preceding
list, modify the MKVSDINI.CMD file with the appropriate PDD
and VSD DLL. The PDD and VSD are defined in the
MMPM2.INI file. Do not include the $ character for the PDD.
In addition, if the DSP requires special loading, use the
appropriate numbers for the .dsp field to signify the
following 1 Load DSP Only 2 Load With MPEG Stream Info.
8.0 CID INSTALLATION
================================================
The following response file keyword must be specified to
allow the OS/2 Plug-in Pack to be installed in a CID environment.
The possible values for the keyword are TRUE or FALSE:
NAV_PRESENT - Netscape Navigator for OS/2 has already been
installed
Refer to section 9.0 of the Netscape Navigator for OS/2 READ.ME file
for additional CID installation details.
The following is an example of a response file used
to install Netscape Navigator for OS/2 Plug-in Pack
where Netscape Navigator for OS/2 is installed in the
C:\NETSCAPE directory and Multimedia support is
installed in the C:\MMOS2 directory:
COMP = OS/2 Multimedia Plug-Ins for Netscape Navigator *
COMP = 16-bit Plug-In Support for Netscape Navigator *
COMP = OS/2 Multimedia MPEG Support *
FILE = C:\NETSCAPE *
AUX1 = C:\MMOS2 *
CFGUPDATE = AUTO *
DELETEBACKUP = NO *
OVERWRITE = YES *
SAVEBACKUP = NO *
NAV_PRESENT = TRUE *
* Indicates a required keyword. Do not include the
"*" within the response file.
Notes:
o The FILE response file keyword should point to the directory
where Netscape Navigator for OS/2 was installed. For
example:
FILE = d:\netscape
o The AUX1 response file keyword should point to the directory
where OS/2 Multimedia was installed. For example:
AUX1 = c:\mmos2
o The value given in the COMP keyword in the response file
must exactly match the string specified by the NAME
keyword of the COMPONENT entry of the appropriate .PKG file.
Refer to approximately lines 77 and 325 in the OS2PIP.PKG
file, and approximately line 2 in the OS2MPEGC.PKG file for
the possible component names to specify.
9.0 KNOWN PROBLEMS
=========================
o Some Windows 3.1 Plug-ins require OLE 2.0. If you do not
have OLE 2.0 for Win-OS2, you can install any 16-bit
Windows 3.1 application that ships OLE 2.0 (such as the
Netscape Navigator for Windows 3.1).
o You may experience problems with the Digigami
install program. You must have OLE 2.0 installed to use
the Digigami Plug-ins.
o The Software MPEG Plug-ins can cause your system to hang
while attempting to close the movie player.
o Sometimes pages that contain plug-ins do not display
correctly. This happens because the webmaster for the
server did not add the MIME types correctly to the web
server software.
o Some Windows 3.1 Plug-ins do not install under OS/2
because they check for the version of Netscape Navigator for Windows
that is installed. You may need to install Netscape Navigator
for Windows 3.1 before you install the plug-ins for OS/2.
o Buffered play is not supported for MPEG-2 and single
stream MPEG devices.
o Sliders do not update with OS/2 multimedia applications on
slower systems.
o Poor video support for software playback with movies over
a LAN.
o Reel Magic Pro and Reel Magic may need a new
AMPMXMCD.DLL fix which corrects the jerky video problem.
o If video problems occur with the OS/2 Multimedia MPEG Support
installation on OS/2 Warp Version 3 systems with S3 cards,
try renaming the YUV_LUT8.LUT file.
o Some content from the Thinkpad CD Sampler has video
corruption during playback of MPEG-2 Transport streams
(files with 2_30 in filename).
o Systems with installed MPEG hardware can hang when
switching between the existing MPEG device and OS/2
Multimedia MPEG Support on Warp 4. The workaround is to
set up the associations (defined in previous section) for
OS/2 Multimedia MPEG Support to be the default MPEG device.
o Problems can occur when opening MPEG-2 content with MPEG-1
only hardware.
