[KBA-00971] How to increase the amount of buffered video in Security Desk - Security Center 5.9 - 5.12

Applies to

Security Center 5.9 - 5.12

Summary

When a user requests video playback or is viewing archives, the workstation downloads the recording from the Archiver. To deliver smooth playback, the workstation buffers the video, and when ready, begins to play the recording. By default, the workstation buffers five seconds of video. You can modify this value to increase or decrease the amount of buffering that takes place.

To modify the amount of buffered video in Security Center:

1. Close Config Tool and Security Desk.
2. Back up the GeneralSettings.gconfig file by copying it to another folder.

   The file is found in C:\Program Files (x86)\Genetec Security Center 5.x\ConfigurationFiles on a 64-bit computer and in C:\Program Files\Genetec Security Center 5.x\ConfigurationFiles on a 32-bit computer.

   CAUTION:
   Only modify a .gconfig file if you are sure that the changes are valid. Incorrect code in a .gconfig file can cause issues on your system or cause your system to go offline.
3. Open the GeneralSettings.gconfig file and add the following code within the <configuration> tags:
   Code

   
   <PlaybackCacheConfiguration PlayableCacheLength="00:01:00" 
   MinimumCacheItemLength="00:00:05" 
   ReverseMinimumCacheItemLength="00:00:20" />
   

   

   PlayableCacheLength

   Minimum amount of video cached during forward playback at 1x.

   MinimumCacheItemLength

   Minimum amount of video downloaded each time the cache gets smaller than PlayableCacheLength during forward playback at 1x.

   ReverseMinimumCacheItemLength

   Minimum amount of video downloaded each time the cache gets smaller than PlayableCacheLength during reverse playback at 1x.

   NOTE: Do not increase the default values unless it is necessary because it will take longer to start playback video.

   Values are automatically adjusted by Security Center when the playback speed changes. For example, when using playback at 2x the values are doubled.

4. Save and close the file.
5. Restart Security Desk.
