Here an example:


Note that actual url was mms://
Usual microsoft tactic.

How about to detect this, and use rtsp as a fallback to mms:// ?

What do you gstreamer developers think?

It seems that things are rather inactive here.

When trying to watch media on the web, I run into lots of unsupported
files, some, and maybe many are supported, but for some reasons don't

I try to provide you with links and detailed explanation of issues.

Also I want to note that for some reason seek doesn't work with the asf
over rtsp, maybe the rtsp is guilty as it never sends PLAY with range
params, instead it sends TEARDOWN

Hope you don't ignore me, as I want to help at least a bit to make
linux on-line video experience a bit better.
