Examples of PluggableAssetTranscoder

com.volantis.mcs.integration.PluggableAssetTranscoder
This interface permits different transcoder products to be integrated with MCS. It is assumed that a single instance of an implementation of this interface will be used by a given instance of MCS. The implementation should, therefore, be thread safe and should not maintain state between invocations.
In order to use a specific implementation of this interface in a deployed instance of MCS, the implementation must be defined as the asset transcoder plugin in the instance's configuration file. See the MCS Administrator's Guide for details.
