Documentation Release Note

Thank you for using RealOne Player! This guide explains RealSystem clip types, such as RealVideo and RealText, and covers the use of the SMIL 2.0 standard, along with the RealNetworks extensions to SMIL 2.0. Although RealOne Player currently supports most SMIL 2.0 features, some additional features will be added at a later date, and will be made available automatically through RealOne Player's autoupdate feature. The following sections describe known issues with content production in this release of RealOne Player.

Tip: See Chapter 1 for summaries of new SMIL 2.0 features, as well as for information about additional changes to this guide from RealSystem Release 8.

Known Issues

You may find discrepancies between the instructions in this guide and RealOne Player performance. Known issues include the following:

Using a Ram file in a SMIL file, which is described in "Using a Ram File as a Source", is not fully functional.

Using a SMIL file in a SMIL file, which is described in "Using a SMIL File as a Source", is not fully functional.

Secondary windows, which are described in the section "Secondary Media Playback Windows", are currently plain windows that do not include the standard RealOne Player skin.

The <area/> tag's nohref attribute, described in "Leaving Out a URL Reference for Hot Spots", does not function.

Hyperlink access keys, which are described in "Opening a Link on a Keystroke", are not functional.

Targeting an HTML frame through SMIL, as described in "Targeting a Frame or Named Window", is not functional.

Contrary to the information in "Replacing the Source Presentation", a source clip stops, rather than pauses, when another clip replaces it in the media playback pane.

Linking to part of a SMIL file, as described in "Linking to a SMIL Fragment", is not functional.

Modifying clip sound levels when a link is traversed is not yet working. This feature is described in "Adjusting Audio Volumes in Linked Presentations".

Push wipe transitions, described in "Fade, Push, and Slide Transition Effects", are not yet functional.

Using a <switch> group to test the viewer's computer hardware and software, which is described in "Switching Based on the Viewer's Computer", is not fully functional.

Prefetching, which is described in Chapter 19, is not functional.

Undocumented Features

The following aspects of RealOne Player functionality have not yet been documented, and in most cases are not fully functional:

Support for media markers. The section "Using Media Markers" is a placeholder for this information.

Support for wallclock timing. The section "Coordinating Clips to an External Clock" is a placeholder for this information.

The min and max timing attributes. The section "Setting Minimum and Maximum Times" is a placeholder for this information.

Time manipulations for animations. The section "Manipulating Animation Timing" is a placeholder for this information.

The skip-content attribute.

The <metadata> tag.

Netscape Navigator 6 Issues

There are two issues currently associated with using Netscape Navigator 6:

If you embed a presentation in a Web page as described in Chapter 20, the path to the .rpm file cannot contain spaces or even escape codes for spaces (%20). This causes Navigator 6 to search for a missing plug-in.

If you browse the HTML version of this guide with Navigator 6, you may not be able to play the linked sample files. If this occurs, you can open the sample files directly from the samples folder. You can also use Navigator 4.7 or Microsoft Internet Explorer (version 5.5 or higher recommended) to browse the guide.

Note: This linking problem affects only local, relative URLs to clips played in RealOne Player. It does not affect streamed presentations in which the viewer launches the presentation from a Web page rendered in Navigator 6.

For More Information: The section "How to Download This Guide to Your Computer" explains how to get a local copy of the HTML guide that includes sample files.
