        static final String PROPERTY_MINIMUM_AVAILABLE_CHUNKS
        DVR Property "dvrMinimumAvailableChunks": for specifying how many chunks must be available in order to play back the DVR recording.

        It is not recommended to have this set to less than three, as players typically require this many chunks.

        Add the property to Application/DVR/Properties section of Application.xml.

        See Also:
        DEFAULT_PROPERTY_MINIMUM_AVAILABLE_CHUNKS, Constant Field Values

        DVR Property "dvrManifestPurgeCacheSize": for specifying how many purged chunks are kept around just in case they are requested.

        When purging chunks occurs, the DVR keeps a few chunks around that normally would have been purged just in case they are requested.

        Add the property to Application/DVR/Properties section of Application.xml.

        static final String PROPERTY_RECALC_DURATION_MAX_AV_DIFFERENCE_TRIGGER
        DVR Property "dvrRecalcDurationMaxAVStartDifference": for triggering recalculation of DVR chunk duration by examining each packet

        This is a fallback setting for when the aligned audio and video packets differ their start times. When this happens, fallback logic is triggered which examines the actual packets and tries to adjust the packet times and duration accordingly.

        Add the property to Application/DVR/Properties section of Application.xml

        See Also:
        DEFAULT_PROPERTY_RECALC_DURATION_MAX_AV_DIFFERENCE_TRIGGER, Constant Field Values

        This is a fallback setting for when the DVR packetizer determines the chunk is quite large, usually because the incoming packet times have done something odd like suddenly diverged. When this happens, asome fallback logic is triggered which examines the acual packets and tries to adjust the duration accordingly.
