I have an IPTV service that worked flawlessly for a long time but for the last month or so most IPTV clients can't even open the streams, not even the latest VLC or Kodi in Windows. The only place I can play it is with PerfectIPTV for Android and with Kodi in a RaspberryPi running a fairly old build.

I've contacted the provider and he says no one has complained so he doesn't know what I'm talking about.

Is there any way I can detect the encoding/codecs of the stream? I've tried MediaInfo and GSpot but both work with local files only.
