    Default DVR issues: Segments not aligned - Transcoding + nDVR + Wirecast - Wowza 3.6.2 Latest

    Hi

    Our hardware setup:
    Dell Poweredge Dual Xenon 5600
    Wowza 3.6.2 Latest production build
    Wirecast 4.3 - Latest version
    Blackmagic Decklink SDI HD stream 1x720p Picture

    Our software setup
    Windows Server 2008 R2 Enterprise
    Wowza config is tuned as recommended in the this post: http://www.wowza.com/forums/content....general-tuning
    Wirecast streaming - RTMP - h264,AAC - Key frame each 2 sec - 2000 kbits video - 96 kbit Audio - Uplink 100 mbits fiber

    Our problem
    - ?DVR is not working in 1/7 of our tests (manifest.f4m) . If we try to playbak the stream without ?DVR = no problem.. (Nothing in the error log)

    - If we run a 6-10 hour long livestream, stop the encoder. We wait 5 minutes then we start the encoder. Then the different bandwidth's (240p,360p, source) are not aligned. After a new restart of the encoder it works fine. (Error logs shows this):

    - After 3-4 hours of streaming we get alignment problems on DVR (Nothing in the access log or error log) playback without ?DVR works like a charm.

    Anyone have any ideas ?

    Test URL:
    http://flashmeeting.exss.no/strobe/?...Button=Connect

    We have been streaming for over 6 hours. Jumping from low quality up to HD is not working very well.. Audio keeps playing and picture freezes for a minute.
    DVR streaming over 3-4 hours is not very stable. This is our 8 or 10th test through version 3.5 - 3.6.2

    If we disable DVR no problem.... Test it out. Remove ?DVR.

    Nothing in the Error logs on the server.

    These messages indicate your audio and video is not aligned or has gone out of alignment. DVR requires audio/video alignment.

    You can debug alignment problems following this guide:
    http://www.wowza.com/forums/content....-packetization

    If the above shows that the audio and video is aligned at the source, then audio and video may be arriving out of sync, which you might be able to fix by setting dvrPacketSortTime Application.xml /DVR Properties container.

         <Property>
              <Name>dvrPacketSortTime</Name>
              <Value>2000</Value>

    I have checked the alingnement on the encoder side and the console show difference [0] - [1] constantly. I have not monitored for hours so if might not be aligned all the time. But is seems like the problem occurs after 3 HOURS every time.

    When I enabled the dvrPacketSortTime as you mentioned i get these messages in the error log:

    Hello, this new error indicates a problem with the encoder sending packets with odd packet times. nDVR reports the issue, but can't fix it.

    You could try setting up a Jitter Buffer to collect and store packets before they are sent to the depacketizer, and enable packet loss logging
    How to turn on an RTP jitter buffer and packet loss logging (RTP and MPEG-TS)

    We are using RTMP from Wirecast 4.3 latest build.

    Im not sure but the last tests shows no Timecode errors. Our internet line is very stable, 100mbit fiber connection .
    Does this jitter config have any impact on RTMP from the encoder ?

    Any ideas ?

    Anybody using Wirecast + nDVR addon + Transcoding + RTMP - Wowza 3.6.2?

    The encoder gives us aligned Audio/Video, how can i debug the alignment on AAC over time? Howto write to log only when its out of alignment ?

    Yes i know.

    • This is SPAMMING my console
    • Nothing of the output is logged
    • The difference is 0 or 1
    • How can i log only errors

    These debug properties only show these messages in the console. They are not written to any logs.
