Streaming using livepkgr Cache issues

[Guest]

[root@localhost channel777]# ls -l

[root@localhost channel777]#

This feild -rw-rw---- 1 ams ams 274679787 Oct  8 11:59 channel777Seg1.f4f really concerns me for 2 reasons

Reason

#1 Why does the file get so large? IE: 14 GB before i restart FMLE and Delete the stream data manually. if i don't delete cache iphone/ipad doesn't play correctly when i restart stream.

#2 When i restart FMLE it doesnt delete cache automaticly like Wowza Server.

Im using AMS Extended 5.0.1 r1076

Any suggestions or comments are welcome

Thanks

You do not have diskmanagment enabled for the livepkgr application in the /application root folder.   It needs to reside in /applications/livepkgr/events/_definst_/liveevent/Event.xml

Google search for samle Event.xml for the livepkgr application.  You can then slice and dice the segments in an array for configurations to suite your server application.

This is what i see in livepkgr Application.xml..

I don't see an option for diskmanagment..

<Application>

    <StreamManager>

        <Live>

            <!-- When enabled, the server will assume that incoming live streams have -->

            <!-- timestamps that are based on an absolute clock, such as a SMPTE time -->

            <!-- signal contained within the encoder's input source.                  -->

            <!-- Default is false.                                                    -->

            <AssumeAbsoluteTime>true</AssumeAbsoluteTime>

            <!-- Allow take over so that encoders that go down (for some reason) and  -->

            <!-- and come back up can immediately republish.                          -->

            <PublishTimeout>0</PublishTimeout>

            <!-- This configuration takes care of situation when the timestamps of    -->

            <!-- certain messages in internally or externally published streams don't -->

            <!-- honor absolute clock contract.                                       -->

            <!-- The possible values are listed below:                                -->

            <!-- 0 disables the work around and is default if the configuration is    -->

            <!--   not present.                                                       -->

            <!-- 1 handles the scenario for externally published streams only         -->

            <!-- 2 handles the scenario for internally published streams only         -->

            <!-- 3 handles both of above                                              -->

            <AdjustForZeroTimeStampMessages>2</AdjustForZeroTimeStampMessages>

            <!-- When enabled along with AssumeAbsoluteTime, the server will          -->

            <!-- assume that incoming live streams will always maintain the           -->

            <!-- timestamps based on an absolute clock across server and stream       -->

            <!-- restarts.                                                            -->

            <!-- Default is true.                                                     -->

            <AdjustForRecordingRollover>false</AdjustForRecordingRollover>

        </Live>

    </StreamManager>

</Application>

Please advise Thanks

It is not Application.xml

<Event>

  <EventID>liveevent</EventID>

  <Recording>

    <FragmentDuration>4000</FragmentDuration>

    <SegmentDuration>400000</SegmentDuration>

    <DiskManagementDuration>1</DiskManagementDuration>

  </Recording>

<HLS>

    <MediaFileDuration>8000</MediaFileDuration>

    <SlidingWindowLength>0</SlidingWindowLength>

</HLS>

</Event>

It is Event.xml located in the livepkgr instance    /opt/adobe/fms/applications/livepkgr/events/_definst_/liveevent/Event.xml

Obviously you will substitute "livepkgr" to the name of your application.

Oh ok i see that my DiskManagementDuration>1</DiskManagementDuration>

is set to 3 by default do i need to change it to 1?

what other things will i change?

[Guest]

No, Diskmanagment is the length in hours that files will be deleted. It will only keep 1 hour of 4 second 400,000kbyte files, in my example.

Ok so you said i dont have diskmanagment enabled?

[root@localhost liveevent]# nano Event.xml

<Event>

  <EventID>liveevent</EventID>

  <Recording>

    <FragmentDuration>4000</FragmentDuration>

    <SegmentDuration>400000</SegmentDuration>

    <DiskManagementDuration>3</DiskManagementDuration>

  </Recording>

</Event>

[Guest]

That is enabled yes.

What also could be skipping the Event.xml

is you are not adding the string identifer in the rtmp sream URI     rtmp://foo.bar/livepkgr/channel777?&adbe-live-event=liveevent

If you don't specificy the string 'liveevent', then it will not use <EventID>liveevent</EventID>

rtmp://foo.bar/livepkgr/channel777?&adbe-live-event=myevent

<EventID>myevent</EventID>

rtmp://foo.bar/livepkgr/channel777

No identifier... Defaults to NULL, no diskmanagment.

I understand now trying it out

[Guest]

Wow. 10gig.. Big file. 

are you missing the main.far or main.asc file in the /livepkgr root?

What is the full RTMP URI?

I have the main.far file in root dir rtmp://foo.foo/livepkgr/channel777?adbe-live-event=carb0n

[bullbelly]

just a quick question was that 45 second delay also in Wowza or just in AMS, I did have on average a 35 second delay with iphones with Wowza, curious if the same will happen in AMS

[Guest]

I forgot what wowzaserver was sorries

Is that normal for iOS devices tho?
