I'd like to store training video segments that our Training Department has made. I added a couple files that are Windows Medai formats to DMX. But they don't seem to stream. If I put the files somewhere in IIS, it works ok.

I'm using the 'Show Direct Link' url as the URL for an object tag in HTML.

Hi Eric,

The module needs to manage the stream itself or security could not be enforced. i.e. I can't tell IIS to serve out file XYZ on disk or someone could access that link directly without passing through the module/security. As a result a file is transmitted over the line by the module in ASP.NET. The downside is that it does benefit from the automatic streaming of IIS.

Regards,

Peter

We are using the "Alive Media Player" module for playing streaming podcasts and videos. The files to be streamed will have to be uploaded separately (outside of DMX) to a folder available to the media player module. Then a reference can be created in DMX that links to the media player module with the correct mediaID in a query string.

Here is an example...scroll down to the podcast section and you can play one of the free podcasts without having to register.

Enforcing security is as Peter suggested an issue. DMX will enforce security on the links within DMX, but if someone knows (or can guess) the file ID to be streamed, then it will play if other security measures are not taken. Our content is not such that for us it's a problem, but I can imagine it would be a serious issue for other applications. For a more secure environment you could consider something like VideoGuard by http://www.hoyasoft.com.

The content of the files is meant to be seen by everyone. Can I do something like set the permissions to 'Unathenticated Users' have view permissions. Then it won't authenticate users?

Hi Eric,

Setting it to 'all users' should work as well. If you use the 'direct link' which goes through Download.aspx then I'm sure that won't challenge the user for authentication. If the link goes through Default.aspx...etc...command=Core_download.. then you need to check the webpage is visible to all users or else DNN will challenge for authentication.

When I right click and choose 'Show Direct Link', it uses a url with the 'command=Core_Download' syntax. How do I use the 'download.aspx' syntax like you suggest?

This is the pattern:

/DesktopModules/Bring2mind/DMX/Download.aspx?TabId=65&EntryId=2793&Command=Core_Download&PortalId=0
