Thread: Error found in Silverlight VOD example

  1. #1

    Question Error in Silverlight VOD example - Failed to download manifest: d

    Hello,

    I tried the Silverlight example for VOD, but it failed to start streaming.

    http://localhost:1935/vod/mp4:sample.mp4/Manifest

    The error is Failed to download manifest: d

    What's wrong with it?

    Thanks.

    Try opening the Manifest URL in a browser.

    Does sample.mp4 exist in the /content folder?

    Hi, Richard

    >>Try opening the Manifest URL in a browser.
    That manifest can be shown in a browser like Firefox.

    >>Does sample.mp4 exist in the /content folder?
    Yes, it exists.

    Please help on this strange situation. Thanks.

    Is there any clue in the Wowza access log show when you try to play the smoothstream?

    Try running Wowza in stand-alone (/bin/startup.bat) mode instead of as a service so you can see log output in the console.

    Hi, Richard,

    I installed the Wowza on another PC, but I still could not run the Silverlight example. Same error as previous.

    The log does not provide much information, only the followings.
    INFO application app-start _definst_ vod/_definst_
    INFO smoothstreaming connect 1950900243 -
    INFO stream create sample.mp4 -
    INFO stream destroy sample.mp4 -
    INFO smoothstreaming disconnect 1950900243 -
    INFO application app-stop _definst_ vod/_definst_

    Any clue?

    Thanks.

    What version of Wowza are you using?

    Are you using the Wowza player: /examples/SimpleVideoStreaming/clientSilverlight/Default.html ?

    Have you added any Modules to /conf/vod/Application.xml ? If so, test without those.

    Hi, Richard,

    Please see my answers.

    >>Are you using the Wowza player: /examples/SimpleVideoStreaming/clientSilverlight/Default.html ?
    Yes.

    >>Have you added any Modules to /conf/vod/Application.xml ?
    No.

    I tried the Wowza 3.1.0 in different OS and the results are as below. I only followed the default instructions to install and no modification was made. Firewall is disabled in
    all OS.

    A) Windows XP = failed
    B) CentOS 6 = works
    C) Ubuntu 10 = works

    It is very strange that the Silverlight player works on CentOS 6 and Ubuntu 10. Do you have any idea why XP does not work?

    Thanks.

    Based on "_definst_ vod/_definst_" it looks like you have a typo in your stream URI.

    Try this: ht tp://[wowza-address]:1935/vod/mp4:sample.mp4/Manifest

    The URLs are identical among all browsers, as I had done the tests many many times.

    Sorry that your answer does not really help.

    Ahh, sorry. I read too quickly.

    Can you mention what streams do work on the XP box? How about RTMP?

    I see that before your edit, your message stated CentOS did not work, but you seem to have fixed it. What change enabled the fix? Perhaps it is related?

    Posting your Application.xml and more complete logs could lead to some insight.
