i can't open JW streams with VLC directly. For example your test file generates the following error.
Your input can't be opened:
VLC is unable to open the MRL 'https://support.jwplayer.com/customer/portal/articles/1403727-what-is-jw-player-
i am simply going Media/Open Network Stream and then Network Tab.
i am running 2.2.4 which is the latest version at this time.
thanks in advance
