## Limitations

WebShow Slide Viewer

#### WebShow has the following limitations.

####

###
- Individual Audio Recordings

Audio recordings must be partitioned into individual files which are then matched with each slide. WebShow does not support playback of a single long recording with automatic slide advance.

###
- Unattended Operation

Unattended (automatic) operation may be possible depending upon the version of internet browser and media player installed on the machine. In many cases, the slides will auto-advance once the playback for each slide finishes. In cases where this does not work, or where you want to auto-sequence slides without audio, you can set a custom timeout value in the slides.js file The automatic advance will be based on the number of seconds you specify and will not take into account the varying length of any associated audio files. Obviously this is of only limited use. Automatic advance is based on a set time is disabled by the setting window.advance=0.

###
- Slides Without Audio Files

If an individual slide will not have an associated audio recording, set the window.audios = value for that file to point to the empty audio.htm file.

###
- Playing Audio Files

WebShow does not actually control or launch the associated audio playback. It simply tells the web browser to load the audio file. Therefore, the web browser must know how to associated the audio format you are attempting to play with a built-in player. This association is usually automatically set up when the audio player is installed.

###
- Stopping Audio During Playback

The slides.js file contains an entry specifying window.silence = 'silent.mp3' This entry must point to an audio recording of "silence". This file is loaded for audio playback whenever the audio is turned off in the midst of playback. (The only way to stop audio playback is to load a new audio file to play "silence" When using an audio player which does not play MP3 files, you will need to make your own short and silent recording and point this entry to your custom silence file. (Without this file, there is no way for the WebShow to stop an audio playback already-underway. However, the user can always stop it manually.)
