    Default live stream time delay (http for ios)

    i play the live stream from wowza media server with rtsp ,there is 4s-8s delay, on my mobile device,while when i play the stream with http there is about 30s-50s delay,so what should i do to reduce the time delay when i play the stream on ios with http?
    thanks!

    hi,

    The delay is nothing but the buffer time. If you go through wowza User guide chapter 5 (Advance configuration Topics) you will see the following details:

    For HTTP Streamers such as Cupertino (Apple HLS), Smooth (Microsoft Smooth Streaming), and San Jose (Adobe HDS), the on-demand startup model doesn't work. An iOS device requires about 30 seconds of video to be pre-packetized before it can begin playback. Microsoft Silverlight clients require three times the key frame duration. Therefore, it's necessary to start the stream prior to the stream being ready for streaming to these player technologies
    Hope it helps to clear your doubts

    regards
    Jason
