A. Adobe Flash® support in XVS-2
Other Format Guidelines
Since Flash® has several unique qualities that make it different than any other content formats that XVS-2
supports, there are some guidelines that need to be considered. Also there are several known issues with
Flash® support in XVS-2 that should be avoided.
• Flash® is Meant Primarily for Web Graphics – It states on Adobe’s website that Adobe Flash®
Player is optimized for publishing graphics on the web or similar computer interfaces. Therefore, if use
of the format deviates too far from this paradigm, then you are running the risk of instability problems
with the content in XVS-2. Here are some of the issues you need to watch for:
- Do not play more than one instance of the same SWF file at the same time in different channels.
- Do not “stress” the Flash® player by loading too many different files at once, or by running playlists
of flash content too rapidly, or shorter than the duration that the file was created for.
- Caution needs to be taken when creating file sizes too big or stretching the file too large in size.
- High frame-rates should normally be avoided where possible.
• Use ActionScript with Care – The scripting engine in Flash® files is extremely powerful. Caution
must be taken when using some of it’s features. For example:
- It is possible to create a Flash® content that completely ignores commands from the control interface
to Play, Pause, or set the CurrentFrame. This of course translates to loosing playback control
on the content in XVS-2.
- The Flash® content should never popup or load other programs, or other web pages, as it will
disrupt the stability of XVS-2.
• Manage Resources Wisely – Proper memory management in ActionScript becomes more important
as XVS-2 must handle potentially number of different content format types at the same time, and
resources should not be wasted.
• Be careful when using RealVNC – RealVNC (http://www.realvnc.com/) is a separate program, used
to remotely control player computers through the network. There are known issues in XVS-2 where
the Flash® ActiveX control will fail to render properly in the player after VNC has connected with the
player machine. It would be a good practice to reboot the player computer after VNC has connected
with it, or restart the player software just before closing the VNC client, so that this issue does not
occur.
