update, fixed it.
aplied new firewall rule;
iptables -I INPUT -p udp -m udp --dport 32768:61000 -j ACCEPT
wasn't nessesary before but videostream runs ok now.

I use Solydk (debian testing) and videostream was working perfect before.
I do get a popup with select chromecast, but when I select my chomecast , no video plays on tv.

I use videostream on a linux system and it also stoped working.
chromecast works ok but plays no video with videostream app , just the videostream logo appears on tv.
Non off the above solutions work either.
Please help.
