    Default Axis IP Camera -> Wowza 4.1 -> HLS -> JW Player..... Buffering......

    I have an Axis IP Camera Q6044 being pulled from Wowza and then pull to the end user via HLS and JW Player. When playing back through JW Player I get lots of spinning wheels every so often. When playing back on VLC, there is no problem. Is there some smoking gun that I am missing? Server resources are plenty.

    Axis Camera:

    wowza Stream Profile:
    Limit Frame Rate to 10 FPS
    GOV Length: 10
    Rate Control: CBR 1500
    Priority: Image Quality

    -------------------------------------

    Stream File:
    rtsp://user:password@camera-ip-address:554/axis-media/media.amp?videocodec=h264&streamprofile=wowza

    -------------------------------------

    Wowza Server Live Application:
    Live Application
    HLS Only checked

    -------------------------------------

    JW Player:
    jwplayer('player123456789').setup({
    file: 'http://wowza-server:1935/Live/camera.stream/playlist.m3u8',
    image: 'http://image-url.com/image.jpg',
    title: 'Live',
    width: '960',
    height: '540',
    mute: 'true',
    autostart: 'true',
    androidhls: 'true',
    ga: '{}',
    sharing: '{}'

    Do you see in your logs if Wowza is having source connectivity issues? If you are unsure, zip up your conf/ and logs/ (include your .stream file) and send it to support@wowza.com for further review.

    Thanks,
    Matt

    in ios playback cupertinoChunkDurationTarget , cupertinoMaxChunkCount , cupertinoPlaylistChunkCount settings are important .Also keyframe interval, and fps of stream is important , recommended keyframe 1 ~ 4 . fps 25-30 as I remember .
    What's your current configuration listed above?

    At first I used the default Application.xml then I added:

    <LiveStreamPacketizer>
    <Properties>
    <Property>
    <Name>cupertinoChunkDurationTarget</Name>
    <Value>10000</Value>
    <Type>Integer</Type>
    </Property>
    <Property>
    <Name>cupertinoMaxChunkCount</Name>
    <Value>10</Value>
    <Type>Integer</Type>
    </Property>
    <Property>
    <Name>cupertinoPlaylistChunkCount</Name>
    <Value>3</Value>
    <Type>Integer</Type>
    </Property>
    <Property>
    <Name>cupertinoRepeaterChunkCount</Name>
    <Value>3</Value>
    <Type>Integer</Type>
    </Property>
    </Properties>
