analyze_media_in_document

The function analyze_media_in_document performs analysis on a media file associated with a document. HPE CFS adds the results of analysis to the document’s metadata. If analysis is not successful, the function results in a Lua error.

NOTE:

You do not need to add the field AUTN_NEEDS_MEDIA_SERVER_ANALYSIS to the document to use this function.

Syntax

analyze_media_in_document(document, params) 

Arguments

Argument Description
document (LuaDocument) The document to analyze. Media analysis is performed on the file associated with the document.
params (table) A table of named parameters to configure media analysis. The table maps parameter names (String) to parameter values. For information about the parameters that you can set, see the following table. For information about how to use named parameters refer to the HPE Connector Framework Server Administration Guide.

Named Parameters

Named Parameter Description Configuration Parameter
request_parameters (table) Additional parameters to pass to the Media Server process action.  
section (string) The name of a section in the CFS configuration file. If you set this then any parameters not set in the params table are read from this section of the configuration file.  
server (table) A table of additional named parameters that configure communication with Media Server. The table maps parameter names (String) to parameter values. For information about the parameters that you can set, see the following table.  
transform (string) The filename of an XSL transform. This is applied to the response from Media Server before the metadata is added to the document. MediaAnalysisTransform

Media Server Settings

Named Parameter Description Configuration Parameter
section (string) The name of a section in the HPE CFS configuration file. If you set this then any parameters not set in the server table are read from this section of the configuration file. If you do not set this parameter, the value of section from the params table is used.  
host (string) The host name of the machine running Media Server. MediaServerHost
port (Number) The Media Server ACI port. MediaServerHost
sslSection (string) The name of a section in the HPE CFS configuration file that contains settings for communicating with Media Server over SSL. MediaServerSSLConfig
readFromOriginalLocation (Boolean) A Boolean that specifies whether Media Server can read the video file from its original location. If you set this parameter, sharedPath is ignored. ReadFromOriginalLocation
sharedPath (string) To transfer the file to Media Server through a shared folder, set this parameter to the path of the folder. Both CFS and Media Server must have access to this folder. If you set readFromOriginalLocation, this parameter is ignored. MediaServerSharedPath

Examples

The following Lua script performs analysis on all documents using the settings in the [MediaServerSettings] section of the HPE CFS configuration file.

function handler(document)
   analyze_media_in_document(document,
        { section="MediaServerSettings" });
   return true;
end

The following example is similar, but overrides the XSL transform and Media Server host set in the HPE CFS configuration file:

function handler(document)
   analyze_media_in_document(document,
        { section = "MediaServerSettings",
          transform = "transform.xsl",
          server = { host="localhost", port=14000 }
        });
end
