4.0 FUNCTIONS INCLUDED IN THIS RELEASE
__________________________________________________________________
The OS/2 Plug-in Pack v. 2.1 enhances Netscape Communicator by
enabling it to play many video and audio files. It also enables
Communicator to use many Windows 3.1 plug-ins.
The Plug-in Pack includes the following features:
o OS/2 video plug-ins supporting various movie file formats
o OS/2 audio plug-ins supporting various audio file formats
o OS/2 MIDI plug-ins supporting MIDI file formats
o Windows 3.1 plug-in support
o Open MPEG support
5.0 MULTIMEDIA PLUG-INS
__________________________________________________________________
The native OS/2 Multimedia Plug-ins in this package provide
support for multimedia MIME Types and file extensions such as
.mpg, .avi, .voc, .aif, .wav, .MID, and many others.
The OS/2 Multimedia Plug-ins provide support for streaming
multimedia. 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
[X:]\MMOS2\INETTEMP (where X is the drive where multimedia
support is installed).
Note: When files are downloaded using the native OS/2 Multimedia
Plug-ins, they are not deleted by the system even after you
have exited Netscape Communicator. This can cause additional
disk space to be consumed. The Multimedia Internet Manager
in the System Setup folder, allows you to remove some or
all of these files, as well as change the directory that
contains this multimedia data.
6.0 SUPPORT FOR WINDOWS 3.1 PLUG-INS
__________________________________________________________________
OS/2 Warp 4.0, OS/2 Warp Server, OS/2 Warp Server Advanced, and
OS/2 Warp Server Advanced SMP Feature support the use of Windows
3.1 Plug-ins.
Some Windows 3.1 Plug-ins require specific installation steps:
o 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.
o Sizzler: Sizzler displays a test window for an extended
period of time the first time it is used. A Timeout
message box might display. Click Retry until the
test window completes its test.
If you prefer not to use the Windows 3.1 Plug-ins support after
installation, delete the Windows 3.1 Plug-in Support component
using the Plug-in Pack installation utility in the directory
where you installed Netscape Communicator.
To delete the Windows 3.1 Plug-in Support:
1. Double-click the Installation Utility located in the
folder where you extracted the os2pip21.exe file.
2. Click Windows 3.1 Plug-in Support, and then click delete.
3. Restart your system.
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 Recommended Hardware Configuration
------------------------------------------------------------------
A Pentium(R) or compatible microprocessor is required. Software
MPEG support can be used with a 486 microprocessor, but the video
quality is minimal.
Software MPEG audio support is available, but performs best on
systems with a Pentium or compatible microprocessor at 90MHz or
higher.
Hardware MPEG audio is supported with IBM Mwave cards or REALmagic
cards.
MPEG hardware is used transparently, if it is available. An
updated REALmagic driver set is provided and installable if the
hardware configuration includes the REALmagic 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 choppy for
polling CD-ROMs.
7.2 Backward Compatibility for MCI applications
------------------------------------------------------------------
A video Media Control Device (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.
7.3 MPEG Limitations
------------------------------------------------------------------
o MPEG-2 Transport streams with buffered play works only 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.
7.4 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.
7.5 Software MPEG Performance
------------------------------------------------------------------
To decrease software MPEG usage, go to the OpenMPEG page in
the Multimedia Setup notebook 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.
7.6 Multimedia Setup Page
------------------------------------------------------------------
If audio fails to play:
1. Open the Multimedia Setup notebook in the System Setup
folder.
2. Click the OpenMPEG tab to go to the OpenMPEG page.
3. Select Software Only.
This change could be necessary for systems containing Audiovation
sound cards.
7.7 Video CD/CD-i Support
------------------------------------------------------------------
Video CD and CD-i content is supported with Software Video CD
in the Multimedia folder. Systems with MPEG hardware, such as
a ThinkPad 760, might have Video CD Player. This allows Video CD
to run through the existing MPEG device. If Software Video CD is
used on systems with MPEG hardware, OS/2 Multimedia MPEG Support
attempts to play the content using hardware. Use Software
Video CD if the system has been customized with OS/2
Multimedia MPEG Support as the default MPEG device.
7.8 Installing MPEG Hardware
------------------------------------------------------------------
OS/2 Multimedia MPEG Support installs hooks for the following
hardware devices:
o ThinkPad 760CD MPEG
o ThinkPad 760ED MPEG
o Sigma Designs REALmagic
o Sigma Designs REALmagic Pro
o Visual Circuits ReelTime
If MPEG hardware is installed after the Plug-in Pack is installed,
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:
o 1 Load DSP Only
o 2 Load With MPEG Stream Info
8.0 KNOWN LIMITATIONS
__________________________________________________________________
The following limitations might occur in the OS/2 Plug-in Pack
v. 2.1.
o During installation, if a message is displayed stating that
you do not have the correct FixPak level installed and you
have verified that you have the correct software requirements
(see section 1.0 Hardware and Software Requirements), then
edit the OSPIP21.PKG file. Delete the following three lines:
FILE
EXITWHEN = INSTALL,
EXIT = WIN16FIXPAK
o LiveAudio/LiveVideo is not supported by the Multimedia
Plug-ins.
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 includes OLE 2.0 when it is installed (such
as Netscape Communicator for Windows 3.1).
o You might experience difficulty with the Digigami CineWEB
installation program. You must have OLE 2.0 installed to use
the Digigami CineWEB Plug-ins.
o The Software MPEG Plug-ins can cause your system to hang
when you attempt 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. For example, the Multimedia Plug-ins support MIME
types such as video/x-flc.
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.
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 The video playback with movies over a LAN is poor.
o REALmagic Pro and REALmagic might need a new AMPMXMCD.DLL
fix which corrects the choppy video problem.
o Some content from the ThinkPad CD Sampler may corrupt video
during playback of MPEG-2 Transport streams (files with 2_30
in filename).
o Systems with installed MPEG hardware can hang when users
switch between the existing MPEG device and OS/2 Multimedia
MPEG Support on OS/2 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 Difficulty may occur when opening MPEG-2 content with devices
that support only MPEG-1.
o AVI video files will not play on OS/2 Warp Server.
9.0 CID INSTALLATION INFORMATION
__________________________________________________________________
CID installation is accomplished by using response files to install
the Plug-in Pack in a CID environment.
A response file is a flat ASCII file that consists of a series of
lines separated by newline sequences (0x0A, 0x0D, or a combination
of these two sequences).
Each line in a response file has a maximum line length of 255
bytes.
A response file has two kinds of lines:
o Comment lines contain only white space characters or have
either an asterisk (*) or a semicolon (;) as the first nonwhite
space character on the line.
o Response lines are used by Software Installer to determine
the options and configurations to install on the target
system.
Response lines have the following syntax:
keyword = value
o Keywords cannot contain imbedded spaces.
o Keywords are not case-sensitive.
You can group keywords together in value lists using the following
syntax:
keyword = (
keyword1 = value
keyword2 = value
.
.
keywordn = value
)
Keyword-value pairs used in a response file can be in any order.
However, only one pair is allowed per line.
If you use any keyword names other than the supported keywords,
they are treated as installation variables. For example,
MONITOR = VGA creates a installation variable with the name of
MONITOR and a value of VGA.
Note: Do not use quotes around the component name, even when the
name is more than one word with blanks between words.
9.1 Sample Response File
------------------------------------------------------------------
The following command is an example of the command needed to start
a response file installation of the Plug-in Pack:
INSTALL /X /A:I /NMSG /O:DRIVE /R:responsefile /L2:outputfile
The following is an example of a response file used to install
OS/2 Plug-in Pack v. 2.1 in a US English environment:
Sample Response File
COMP = OS/2 Multimedia Plug-Ins for Netscape Communicator
COMP = 16-bit Plug-In Support for Netscape Communicator
COMP = OS/2 Multimedia MPEG Support
CFGUPDATE = AUTO
DELETEBACKUP = NO
OVERWRITE = YES
SAVEBACKUP = NO
NAV_PRESENT = TRUE
9.2 OS/2 Plug-in Pack v. 2.1 keywords
------------------------------------------------------------------
The following response file keyword is required to install the
Plug-in Pack in a CID environment. The possible values for the
keyword are TRUE or FALSE:
NAV_PRESENT - Netscape Communicator 4.04 for OS/2 Warp has
been already installed
Notes:
o The FILE keyword should point to the directory where
Netscape Communicator was installed.
For example:
FILE = C:\COMM404
o The AUX1 keyword should print 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 .PKG file. Refer to the OS2PIP21.PKG
file at approximately line 125 for the OS/2 Multimedia
Plug-ins, 295 for the 16-bit Plug-in Support, and 370 for the
OS/2 Multimedia MPEG Support for the possible component names
to specify.
9.3 Software Installer keywords
------------------------------------------------------------------
Software Installer supports the following keywords:
AUXn (conditionally required)
Specifies the new default path for the auxiliary directory,
where n is any number between 1 and 18. (There are 18
possible auxiliary directories: AUX1, AUX2,...AUX18.) This
keyword is used only for installation processing.
This AUXn value is used in place of the AUXn keyword of the PATH
entry of the package file. This keyword is required if you have
specified an AUXn keyword in the PATH entry.
CFGUPDATE (required)
Specifies whether the CONFIG.SYS file is automatically updated.
Valid values for this keyword are:
AUTO Automatically updates CONFIG.SYS
MANUAL Does not update CONFIG.SYS
COMP
Specifies the unique name of a component of the product for which
passed information applies. There can be a maximum of 100
components. The COMP value must match the NAME keyword of the
COMPONENT entry in the package file.
Note: Do not use quotation marks around the component name, even
when the name is more than one word with blanks between words.
COPY
Specifies the source and target files for a copy process. The
format of this keyword is:
COPY = source_filespec target_filespec
If the target_filespec already exists, it is overwritten. If
either file specification is not valid, the copy is not made.
DELETEBACKUP (required)
Specifies whether to delete only the backup versions of the
product or to delete the entire product. Valid values for this
keyword are YES and NO. It is required because an existing
dialog requests this information in the attended mode.
If an unattended deletion is attempted and the DELETEBACKUP is not
present in the response file, the deletion fails with an
EPFIE212 error.
FILE (conditionally required)
Provides the new default path for the file directory. This
keyword is used only for installation processing.
This FILE value is used in place of the FILE keyword of the PATH
entry in the package file. This keyword is required if you have
specified a FILE keyword in the PATH entry.
INCLUDE
Specifies which general response files to include with a
specific response file. The format of this keyword is:
INCLUDE = filespec
Where filespec is the general response file to be included. If
the file specification contains any global characters (* or ?),
the first file found that matches the specification is included.
If the specification is not valid, no general response file is
included.
Note: You cannot have more than five levels of included response
files.
The following search order is used to find the general response
files specified.
1. The fully qualified file specification, if specified with
filespec.
2. The current directory.
3. The file name together with the /G: invocation parameter.
4. Each directory in the PATH environment variable.
5. Each directory in the DPATH environment variable.
OVERWRITE (required)
Specifies whether to automatically overwrite files during
installation. Valid values for this keyword are YES and NO.
This keyword is required for unattended processing.
SAVEBACKUP (required)
Specifies whether to save a backup version of the product when
it is updated. Valid values for this keyword are YES and NO. It
is required for unattended processing because an existing dialog
requests this information in the attended mode.
USEREXIT
Specifies the name of an exit that you want started. The format
of this keyword is:
USEREXIT = filespec
Where filespec is the name of a user exit. If the file
specification contains any global characters (* or ?), the first
executable file found that matches the specification is started.
If the specification is not valid, Software Installer displays an
error message.
The following search order is used to find the specified user
exit.
1. The fully qualified file specification, if specified with
filespec.
2. The current directory.
3. Each directory in the PATH environment variable.
4. Each directory in the DPATH environment variable.
If the exit does not already exist on the system, you must pack
the exit in the INSTALL.IN_ file.
WORK (conditionally required)
Provides the new default path for the data directory.
This WORK value is used in place of the WORK keyword of the PATH
entry in the package file. This keyword is required if you have
specified a WORK keyword in the PATH entry.
