Question

F4M document contains errors - URL missing from Media tag

I feel like I'm getting close to finally get a live stream to work correctly in 4.5

I can see the streams being recorded in the following directories

     C:\FMSHOME\applications\livepkgr\streams\_definst_\liveevent1

     C:\FMSHOME\applications\livepkgr\streams\_definst_\liveevent2

     C:\FMSHOME\applications\livepkgr\streams\_definst_\liveevent3

Each directory contains five files: bootstrap ,control, meta, f4f, and f4x.

I have a single file called Event.xml in the directory: C:\FMSHOME\applications\livepkgr\events\_definst_\liveevent

<Event>

<EventID>liveevent</EventID>

<Recording>

<FragmentDuration>4000</FragmentDuration>

<SegmentDuration>16000</SegmentDuration>

<DiskManagementDuration>3</DiskManagementDuration>

</Recording>

</Event>

However the client player receives the exception F4M document contains errors - URL missing from Media tag.

If this file is dynamically generated on the fly by the server what do I need to change to resolve this issue?

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

            <param name="FlashVars" value="src=http://myserver/hds-live/livepkgr/_definst_/liveevent.f4m"></param>

            <param name="allowFullScreen" value="true"></param>

            <param name="allowscriptaccess" value="always"></param>

            <embed src="StrobeMediaPlayback.swf"

                   type="application/x-shockwave-flash"

                   allowscriptaccess="always"

                   allowfullscreen="true"

                   width="600"

                   height="409"

                   FlashVars="src=http://myserver/hds-live/livepkgr/_definst_/liveevent.f4m">

            </embed>

</object>

Thanks Again!

    Hi,

    This error is usually observed when you do not have entries for all the streams in the manifest.xml file. For eg - if you are publishing 3 streams to the FMS, there should be a manifest.xml file containing entries for each one of them in a media tag, like this -

    <media streamId="liveevent1" bitrate="100" />

    <media streamId="liveevent2" bitrate="200" />

    <media streamId="liveevent3" bitrate="350" />

    If you are using the default manifest.xml that comes with FMS, inside C:\FMSHOME\applications\livepkgr\events\_definst_\liveevent\manifest.xml, then make sure you change the streamIds to your custom setup.

    Please try the following and let me know if you face any other problem.

    I've got a single bitrate stream working now I need to figure out how to configure multi bitrate streams.

    I thought you needed to remove the manifest.xml and only have an event.xml file in your event folder.

    So if I encode 3 streams using bitrates of 100, 200, and 350. I would encode useing livestream%i?adbe-live-event=liveevent

    My C:\FMSHOME\applications\livepkgr\events\_definst_\liveevent\manifest.xml file would look like:

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

         <media streamId="livestream1" bitrate="100" />

         <media streamId="livestream2" bitrate="200" />

         <media streamId="livestream3" bitrate="350" />

         </manifest>

    

    Would my client player still access the multi-bit live stream using this url? Or should my url be different.

    http://myserver/hds-live/livepkgr/_definst_/liveevent/liveevent.f4m

    

    Thanks for the help.

    Yes, the manifest file url would be the same - http://myserver/hds-live/livepkgr/_definst_/liveevent.f4m.

    Are you able to get things to work this way?
