    You could play the stream for awhile in a Flash RTMP client, then look at the access log, find the x-event "destroy" for that session and look at sc-bytes (server to client bytes) and x-duration fields

    sc-bytes * 8 / x-duration = bitrate

    hi,
    We use WOWZA to restreaming a rtmp source from internet.
    we look at the access log and find the "x-event","sc-bytes"=3322526,"x-duration"=1.115
    the bitrate of this stream is 2314087bit/s or ??


    Thank you

    Hi,
    I can see you have a typo you put "sc-bytes"=3322526" which has an extra "3" at the start.

    sc-bytes x 8 = sc-bits /1.115 = bits per per second
    322526 x 8 = 2580208 /1.115 = 2,314,087 which is 2.3 Mbps.

    I recommend a much longer connection time to make the reading more accurate as you will get a burst of data at the start for a new connection.
    I think around 60 seconds should be enough to get a clear average bitrate.

    Thank you Jason,
    May I know more specification of myStream in WOWZA??
    ex: resolution of stream, frames per second, audio bitrate

    You can get a lot of info in the Wowza logs by turning cupertinostreamingpacketizer in the Application.xml /LiveStreamPacketizers. When packetizing begins Wowza show audio and video details;

    Hi,
    In any of the live tutorials you will see they are all configured for packetizing cupertino, smooth and sanjose.
    You only need to add cupertinostreamingpacketizer to the "Streams/LiveStreamPacketizers" section of the Application.xml and make sure "cupertinostreaming" is in the "Streams/HTTPStreamers" section as well.

    You can find the live RTMP based encoder tutorial for reference here,
    configuration guide
