GetLatestRecord

Retrieves the latest record that has been added to a track, or the latest records for all tracks.

NOTE:

This action only returns records from requests that have a status of processing. Media Server does not return records from requests that have a status of finished. You can use this action to confirm that Media Server is processing video correctly. You should not use this action to retrieve results from Media Server. If you need to retrieve results through ACI, Media Server provides an ACI response output engine.

Type: synchronous

Parameter Description Required
Compress A Boolean value (default true) that specifies whether the action returns image data in compressed JPEG format, rather than PNG format. No
Token The asynchronous action token, returned by the process action, that specifies the processing request to return records from. If you do not set this parameter, Media Server returns records for all processing requests. No
Tracks A comma-separated list of tracks to return the latest records from. If you do not set this parameter, Media Server returns the latest record from each output track. To return the latest records from all tracks, set this parameter to an asterisk (*). No

Example

/action=GetLatestRecord
              &Token=...
