SiverlightMediaFramework - How to control HSS download strategy in case of chunk errors (e.g. http 404) RRS feed

  • Question

  • Hi silverlight community,

    Could please assist with next situation during SmoothStreaming playback.


    SMF starts to download HSS manifest & chunks, then chunks start to be unavailable in one moment:


    So many of 404 responses in short time (about 1 second) & message: "Exception - 3050 Failed to download 50 consecutive chunks for stream type Video - halting playack"

    50 Consecutive Chunks Error


    We need somehow control download strategy during an error: specify count of retries and interval between them. E.g. 5 retries with interval of 3 seconds. But not 50 requests!

    This feature/hack could decrease server payload.

    More details:

    SMF version: 2.2012.605.0

    Target Browsers:

    IE11 on Win, Safari on Mac

    Almost the same SMF is hosted here:

    Best regards,

  • Hi AlexKch,

    As far as I know, Silverlight Media Framework (SMF) is an open source framework that allows developers to build great custom media players for IIS Smooth Streaming delivery. Now, it is called Microsoft Media Platform.

    Microsoft Media Platform : Microsoft's open source media player framework - a component of the Microsoft Media Platform. This project was formerly known as the Silverlight Media Framework (SMF).

    So, I suggest you can visit the Microsoft Media Platform issue center for getting suitable help.

    Your understanding and cooperation will be grateful.
