    Post RTMPT http tunneling result very high http get requests


    I'm using rtmpt protocol streaming live and vod video ( reason, to pass a corporate reverse http proxy).
    However, I've performance issues, the http get request is extremly high with relative low number of connections! How can I increase the http get buffer size to reduce the get request? I'm using Wowza version 2.2.4.

    Thanks in advance.

    Try a longer key frame frequency (i.e., higher gop) because Wowza breaks chunks on key frames for RTMPT delivery.

    Hi Richard,

    I've tried with your suggestion to increase the key frame interval, here is my test data :

    The live stream is rtp stream : 500kb/s, resolution 320*240

    playback with Wowza provided test flash player using rtmpt protocol :

    Key frame interval http request
    1 sec ~ 525 requests/60s
    2 sec ~ 540 requests/60s
    3 sec ~ 560 requests/60s
    4 sec ~ 530 requests/60s
    5 sec ~ 620 requests/60s

    Clearly these data didn't show me the effects of decreased number of http requests by increased key frame interval,
    did I something wrong? Can you give me some more advice?
