No audio with swf when I go live!

Tags: #flash #audio #dreamweaver #shockwave

My webinar works fine in dreamweaver when I preview in browser but when I go live there is no audio.

The webinar a swf file, all related files are within the same folder, and the entire folder is on the server.

    Can you change it to something other than SWF and try a non-Flash method?

     

    Additionally, (and this is an occasional issue with certain servers) have you told your server that the audio portion of the Flash file is playable? With .ogg video and audio, with many Linux-Apache systems, you have to enable that kind of MIME type in the .htaccess file.

    Can you give us a link to your test page?

    To be honest, I have zero experience with Webinar.  But I work with media all the time, and I'm wondering if you have actually loaded all the necessary files to the correct folder on your server.

     

    I can see these by direct URL:

    http://lakestatesfiresci.net/webinars/Recordings/20120119REDPINE/index.html

    http://lakestatesfiresci.net/webinars/Recordings/20120119REDPINE/replay.swf

     

    But I can't find any of these:

    numbers.flv

    coverimage.jpg

    webinar.swf

    Make sure you upload the files to the server with the exact same file structure that was present in your desktop version. The sound would have had to be linked in the .swf file so it's not that, but the actionscript used to play the sound will use a relative path. If you change any of the folder names, locations etc, it could mess up the file.

    If the directory structure is the same, I think this might be a MIME issue.  Contact your web host and tell them to enable both SWF & FLV MIME types (audio & video).   You probably can't do it yourself because you're on Win IIS.

    Is the audio in the .flv container? Looks like the .flv is only audio and the graphic elements are completely in the .swf, correct?

    While all the other files do download,

    http://lakestatesfiresci.net/webinars/Recordings/20120119REDPINE/a9e42 14527.flv

    returns file not found.

    While it could be a MIME issue, I'd have to question any Web host in this day and age that hasn't yet set the correct MIME type for .flv files.

    But however you slice it, the .flv file is not loading in the browser.

    Until you/we can do a direct download at the URL listed above, the audio will not work.

    There are a handful errors that occur when the .swf communicates with the browser and other internal files. Please see screenshot:

    1. If your .swf links to certail files from your webinar provider, you need crossdomain.xml to be present in your root folder. Also, I'm assuming your webinar provider already stores a copy of crossdomain.xml on their server as they're a webinar host. In your case, reference to crossdomain.xml is present in your code or your .swf is already looking for it (it must be hard-coded into your .SWF), but the file path is invalid. See here for Adobe's specifications on making a crossdomain.xml file - Download Adobe Crossdomain Policy File Specs from Adobe
    2. A couple of .flv files are missing in the path that your .swf is looking at. Assuming your webinar provider only gives you .swf and not .fla, there's not much you can do but to keep the file paths intact the way you receive it from your webinar service provider.

    Did you try resetting your browser's cache? If not, can you try this and then reload your page locally to see if it still works?

    Testing the index.html file on your local machine simply means that all the files needed to play your project are on your local machine. That does not give any indication as to what's on the server.

    http://lakestatesfiresci.net/webinars/Recordings/20120119REDPINE/a9e42 14527.flv

    still returns file not found.

    Most likely the audio is in that .flv file and without that file you will have no audio. It's not a cross domain issue it's a missing file issue.

    You will have to look on the server and make sure that the correct file is in the correct folder and that it's correctly named.

    All of the .flv files linked to above return "File not Found"...

    in other words they do not exist at the links above.

    So it's not that the .flv files don't work, they don't exist.... at least at the links you provided.

    Hello Elisabeth,

     

    you are right, the swf files are there, BUT your videos are very long, and it will take a very long time to load them. So it might be necessary to split your video into chapters or segments.

     

    And I for my part can't find - like others -  a flv file.

    Well there are only a few possibilities if you say that you've transferred them....

    The .flv files didn't transfer correctly or the Web host doesn't have the correct MIME type set for .flv.

    Can you see and compare file size of the files on local and files on server? They should be the same size. If files on server are smaller, then they didn't upload correctly.

    You might also want to try using a real FTP program rather than DreamWeaver to upload files to the server. For PCs, use Filezilla:

    http://filezilla-project.org/

    For Mac:

    http://cyberduck.ch/

    For MIME issues, contact your Web host.

    But the browser will not be able to download the .flv file until you can also do a direct download.... as in posting the like above.

    As long as those links return file not found... you won't have audio.

    So I nailed it.
