If I detect if the MMS link is connected successfully? What to do with it

If I detect if the MMS link is connected successfully?
For example, an address like this
Mms://live.cri.cn/oldies

If there is a change in the source station I would like to check if this link can be linked successfully

Previously used the Get_headers () function to detect HTTP files
But this function doesn't seem to work for MMS.

Is there any other way to test it?

------Solution--------------------
Get_headers: The sending server responds to HTTP requests
Get_headers (string url[link format])
Get_headers () returns the server HTTP request in the form of an array. If execution fails, it will return false and an error in the horizontal e_warning ".
The optional parameter is set to 1,get_headers () to analyze the system's response speed and the keys in the set array.

That MMS is a streaming media protocol right?!
