Thread: Timecodes out of order

  1. #1

    Default Timecodes out of order

    How do I interpret these messages? What is the [audio}: xxxxx:yyyyy. Is the xxxxx the expected and the yyyyy the actual timestamps? Or is it something else? They always seem to be around 21 to 22 apart. Is that a clue of anything?

    Second question. What is Wowza doing when it gets this warning? Is it tossing the audio packets out? I see the video lagging the audio so it seems like the audio may be running faster because wowza is tossing packets, but that's just a theory. What actually happens?

    Hi
    Generally this indicates an encoder issue. It also could be an issue when the machine CPU utilization, or GPU utilization, is maxed out. To debug, see How to debug AAC or MP3 timecode issues with cupertino packetization.
    Try using Advanced Stream Monitor. If you see this message immediately after the stream is published before packetization starts, it can be ignored.
