    Unhappy Lip Sync issue - Cisco telepresence content server

    We are using cisco telepresence content server 6.2 . Flash content is streamed live from Cisco TCS to wowza .. then it is published to CDN network .
    Voice and video doesnt sync . video is faster than voice.
    I tried sort buffer and packetisation as specified in the forum but i couldnt resolve the issue . Let me know if
    Sort buffer - 250/750 /2500 - tried them all

    Video is fine for first 2 hours and lip sync occurs beyond that time .
    Also am not sure if this is tc(0) or tc(1)..
    tc(a/v/d):15576632/15576627/15576483

    Hi,

    How to make the Keyframe Constant in wowza .

    We are using transcoder add on . each encode in Transcoder has the following settings

    Key Frame Interval
    Use key frame interval of:
    60 frames per second

    We wanted to make this constant . Akamai specifies the keyframe varies drastically .
