    OSMF 1.6.1/2.0 / Strobe Live issue : Framework can't handle an empty f4m descriptor?

    digitalbise

      Hi,

       

      suppose that in a live media stream, the f4m descriptor just contains the following:

       

      <?xml version="1.0" encoding="utf-8"?>

      <manifest xmlns="http://ns.adobe.com/f4m/1.0">

      <id>live2</id>

      <mimeType>video/mp4</mimeType>

      <streamType>live</streamType>

      <deliveryType>streaming</deliveryType>

      </manifest>

       

       

      The official Strobe Player can’t handle this situation (see answers to comments in http://www.osmf.org/dev/1.5gm/setup.html, I tried Strobe 1.5 and I get an error when connecting) so I wonder if this is a general issue with OSMF, as I haven’t been able to make it work with my own OSMF-based player (I tried both 1.6.1 and 2.0).

       

      On the other hand in my attempts, after Flash Media Live Encoder has started streaming and the Wowza server fills the f4m descriptor with media-related data, I can load Strobe or my own OSMF-based player and the playback starts without problems.

       

      <manifest xmlns="http://ns.adobe.com/f4m/1.0">

      <id>live2</id>
      <width>480</width>
      <height>360</height>
      <mimeType>video/mp4</mimeType>
      <streamType>live</streamType>
      <deliveryType>streaming</deliveryType>
      <bootstrapInfo id="bootstrap478000" profile="named" url="playlist_b478000_w478000.abst" />
       <media bootstrapInfoId="bootstrap478000" width="480" height="360" bitrate="466" url="media_b478000_w478000.abst/">
      <metadata>AgAKb25NZXRhRGF0YQMACXRyYWNraW5mbwoAAAABAwAEdHlwZQIABWF1ZGlvAAZjb25maWcCAAQxNDA4AAtkZXNjcmlwdGlvbgIAV3tBQUNG

      </manifest>

      So my conclusion is: currently I must not open the player before the event starts (which I cannot know in advance of course), or it will find an empty f4m and will get stuck unless the web page embedding it gets reloaded.

       

      Is there a way to solve it? I tried with OSMF 1.6.1 and OSMF 2 in my custom player and strobe 1.5 .

       

       

       

      1. p.s.
