Help ! master.m3u8 pointing to wrong video !

Hi !

I'm trying to download this football match from this website (before downloading i always try to see if livestreamer is capable of playing it)

(you may need an italian vpn):
http://www.sportmediaset.mediaset.it/mondiali-russia-2018/fifa/calendario.shtml?match_...4-5d84a42a50b9

I'm on win10 pro and using firefox (60.0.2 version) for the purpose.
Using "browser console" (tools--->web developer--->browser console) and filtering the results searching "m3u8", i get these links:

Right click on "master.m3u8" (only master.m3u8 has the whole link with hdnea exp hmac parameters) and then the weird thing:

If i use livestreamer (1.12.2 version) with this syntax:

vlc opens up but it shows a complete different video ! It's a tv-series episode broadcasted few hours before the game !


Then i tried the audio link (vlc opens only if i use hls; hlsvariant doesn't work)

and vlc plays the audio track of that same tv-series episode !

It's not only this game to have this weird behaviour, but it happens for EVERY game !

Every single game is correctly shown through website player but their matching "master.m3u8 link" points to a complete different video !

Than i tried streamlink (0.13.0 version) but this shows up:



This website requires to login (creating an account is totally free) but if you don't do this, every game starts playing anyway,
but after few minutes a message appears inviting you to login in order to keep watching the football match.

I tried both ways (logged and not) but nothing changes ! Always same wrong videos !

So it looks like login credentials have no influence on getting the right link.

So whatever match i want to download, i always get a wrong video despite using the master.m3u8 link provided by firefox browser console !

Do you have any idea how to manage to get the correct master.m3u8 ?

I really hope you can help me out !
