    Default Audio delay during live streaming

    Hi

    I am using Wowza for doing live streaming and I just found some case since I got the audio delay around 2 minute after the video.
    I used Adobe flash media encoder to stream with around 200 kbps.

    How could I figure out the delay?

    Thanks

    Hi,

    The delay is usually associated with bandwidth issues. Can you please provide more details about your setup? Are you also recording the live stream?
    Does the delay manifests itself on the live stream or on the recorded vod? Both?
    What are your FMLE encoding settings?
    What about the Wowza application StreamType?

    Hi Zoran

    I just used FMLE3.2 with configuration using my webcam camera
    Format : H264
    Frame rate: 20 Frame per sec
    Input size 320x240
    Bit rate 200 kbps
    Output Size 320x420

    Audio part:
    Format: mp3
    Channel: stero
    Sample rate 44100 Hz
    Bit rate: 56

    I didn't record at all and the type of application is live
    So the bandwidth total is 256 kbps, and this is quite pretty low, and if there is the issue on configuration please help me to figure out

    Thanks,
    Mark

    What is the available bandwidth between FMLE and the Wowza server you are publishing to?
    There is more than 256Kbps available right? What about other network traffic?

    Is the delay apparent immediately, or does it start off short and become longer over time?
