    Hello there,

    HTTP streaming sends chunks to the client. The client needs 3 chunks cached before it starts playing.

    By default Wowza is set to send 3, 10 second chunks in each packet sent to the client. You can modify this behavior by editing the Application.xml file.
    This guide explains how to control how the Sanjosestreaming (Adobe HDS) segmenter segments an incoming live stream:

    Chunks must start on a key frame. So it is best to use a key frame interval that is factor of the sanjoseChunkDurationTarget setting.

    Kind regards,

    Salvadore
