Question

Publishing video live stream by HLS

We've setup an AMS 5 environment and publish a live video on an URL like : rtmp://<my_ams_host>/livepkgr/events/_definst_/liveevent/testlive02 then we were able to read the stream by RTMP as well.

But we wanted to read the live stream using HLS protocol. We've setup the bundled apache (with AMS) as recommaned in the technical documentation.

Normaly we would be able to read the stream at the URL : http://<my_ams_host>/events/_definst_/liveevent/testlive02.m3u8.
But we got 404 errors as if the resource was not found.

The "hls-live" location is configured as following

<Location /hls-live>

    HLSHttpStreamingEnabled true

    HttpStreamingLiveEventPath "/opt/adobe/ams/applications"

    HttpStreamingContentPath "/opt/adobe/ams/applications"

    HLSMediaFileDuration 8000

    HLSSlidingWindowLength 6

    HLSFmsDirPath "/opt/adobe/ams"

    HttpStreamingUnavailableResponseCode 503

    HLSM3U8MaxAge 2

    HLSTSSegmentMaxAge -1

    HLSMetaMaxAge 3600

    HLSMaxEventAge 300

    Options -Indexes FollowSymLinks

</Location>

The hls module is loaded. Vérication made by the following command

sshams@mv271:~$ sudo /opt/adobe/ams/Apache2.2/bin/apachectl -M

    Hi Mamisoa,

    Welcome to adobe forums.

    Kindly check your HLS url it should be like this : http://<my_ams_host>/hls-live/livepkgr/_definst_/liveevent/livestream.m3u8 and make sure that you play HLS stream on Mac safari browser.

    And please place the crossdomain.xml file inside your server webroot so that It can allow connections from other domain, you can edit this xml file based upon your requirement.

    Here is the sample crossdomain.xml:

    <?xml version="1.0"?>

    <!-- http://www.osmf.org/crossdomain.xml -->

    <!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">

    <cross-domain-policy>

        <allow-access-from domain="*" />

        <site-control permitted-cross-domain-policies="all"/>

    </cross-domain-policy>

    Let me know if you need any help.

    Regards,

    Puspendra

    Hi Pushpendra and thanks for your answer.
    But, unfortunately I keep on to have the same error.

    Actually, I've made a mistake in my message above. My HLS-LIVE URL is http://<my_ams_host>/hls-live/livepkgr/events/_definst_/liveevent/testlive02.m3u8.
    Could you explain me why I had the following line in my apache's error_log

    ...

    Why did Apache try to find the resource under the "webroot" directory. I thought it's a kind of "virtual resource". Isn't it ???

    Thanks in advance.

    Mamisoa.

    Did you placed crossdomain.xml file inside webroot of AMS.
