    Question nDVR manifest.txt file contains <PurgeTime>-1</PurgeTime>

    Hi:
    I am using a nDVR add-on to record 4 hours streams. I found some of the manifest.txt files in dvr folder contains the wrong time value like this:
    <dvrManifest version="1.0" >
    <CanRecord>true</CanRecord>
    <CanPlay>true</CanPlay>
    <HasEncryption>false</HasEncryption>
    <ChunkGrouping>600</ChunkGrouping>
    <PurgeTime>-1</PurgeTime>
    <CurrentTime>-1</CurrentTime>
    </dvrManifest>
    I've tried to reset the stream, and the value do not change. But the stream can play normally. Is this right?
    I've seen the normal stream's manifest.txt is as follows:
    <dvrManifest version="1.0" >
    <CanRecord>true</CanRecord>
    <CanPlay>true</CanPlay>
    <HasEncryption>false</HasEncryption>
    <ChunkGrouping>600</ChunkGrouping>
    <PurgeTime>2001786295</PurgeTime>
    <CurrentTime>2016186295</CurrentTime>
    </dvrManifest>
    And if the -1 value is right, how can I distinguish the normal stream from abnormal stream.
    Thank you.

    Default

    Value of -1 (or greater) is valid for PurgeTime and CurrentTime properties. The manifest.txt file is an internal file managed by Wowza Server and what is in memory will overrule the values in this file. Do not edit or leave this file open while running Wowza Server with nDVR.

    If you have problematic streams, look in [install-dir]/logs/wowzamediaserver_access.log file for hints. The Wowza nDVR Quick Start Guide has a Best Practices section which provides tips for a successful nDVR recording.
