Run Analysis on All Supported Video Files

CFS includes a Lua script, scripts/VideoAnalysis.Lua, to run analysis on all video files that Media Server can process. The script reads settings for the task from the [VideoServerSettings] section of the CFS configuration file.

To run video analysis on all supported video files

  1. Open the CFS configuration file.
  2. Find the [ImportTasks] section of the configuration file, or create this section if it does not exist.
  3. In the [ImportTasks] section, configure a Pre or Post import task to run the Lua script scripts/VideoAnalysis.Lua.

    For example:

    [ImportTasks]
    Pre0=Lua:scripts/VideoAnalysis.lua
  4. Create a new section in the configuration file, named [VideoServerSettings].
  5. In the new section, set the following parameters:

    VideoServerHost The host name and ACI port of your Video Server. To distribute requests between several servers, specify a comma-separated list of servers.
    VideoAnalysisTransform (Optional) To transform the metadata produced by Video Server, before CFS adds the data to your documents, set this parameter to the path of the XSL transformation to use.
  6. Specify the Video Server configuration file to use for running analysis:

  7. Specify how to send video to Media Server:

  8. Save and close the configuration file.

Examples

The following example configuration runs video analysis for all supported files ingested by CFS, using a configuration named broadcast that exists on the Media Server machine:

[ImportTasks]
Pre0=Lua:scripts/VideoAnalysis.lua

[VideoServerSettings]
VideoServerHost=localhost:14000
VideoServerConfigurationName=broadcast
ReadFromOriginalLocation=TRUE

If your CFS and Media Server are running on separate machines, you can configure CFS to copy video files to a shared folder:

[ImportTasks]
Pre0=Lua:scripts/VideoAnalysis.lua

[VideoServerSettings]
VideoServerHost=videoserver1:14000,videoserver2:14000
VideoServerConfigurationName=broadcast
VideoServerSharedPath=\\server\videofiles
