Windows Media Streaming MMS/HTTP Problem

Postby manolamancha » 11 Feb 2010 03:07

Hello! I ran into a problem recently with a stream protected with one-time-use tokens that wouldn't play properly in VLC (tried 1.0.3 and 1.0.5)
The initial link to the stream is via HTTP and it returns a link to an edge server with a token embedded in the URL. When VLC accesses the new URL and the server detects a non-Windows player, it returns an ASX playlist with a pair of HTTP streams containing the same tokens and &MSWMExt=.asf appended. Now when VLC sees the .asf extension, it looks like it automatically tries to connect with MMS instead of HTTP. It will try MMS over TCP, then MMS over UDP and finally fail back to HTTP. However in this case, when it fails back to HTTP, the tokens have already been used on the server and it rejects the HTTP calls as 401 Unauthorized.
If you use Windows Media Player 11, it will connect to the redirected URL, perform some negotiations and start streaming what looks to be MMS over HTTP. So maybe this is a feature request to support MMS over HTTP, or maybe it would be possible to add a flag to force the usage of HTTP instead of MMS? Or any other ideas? I really appreciate the help and here's a link to test:
