    hello world,
    I would like to know if is possible with wowza, stream HTTP real time streaming?
    when I use HLS .m3u8 and compare with rtmp,
    rtmp -> is live, but .m3u8 is everytime delayed, not direct open,...

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

    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.

    Thank you for you reply,
    but what's the best configuration, for good and fast http live stream?

    Chunks must start on a key frame. So it is best to use a key frame interval that is factor of the cupertinoChunkDurationTarget setting.
    Try 2 second key frame frequency and cupertinoChunkDurationTarget "2000" (2 seconds)

    I suggest trying a much lower bitrate. Something more along the lines of 400 - 800kbs.

    Also take a look at this guide:
