thanks for your reply, roleen0317. pepperflash didn't fix my problem unfortunately. i don't know how to update to opera 33.

I tried sudo apt-get update, but i'm still on 31

Sorry for the double post, I don't know how to edit my post. This problem seems to be very random because some videos work from a specific channel and others don't. I see not pattern. Maybe it is related to some A/V codecs?

Hi, i'm using Opera 31.0 on Linux Mint 17.2 Cinnamon x64, installed from the software center.

It's nice to see 60fps videos working on Youtube in Opera compared to Firefox which still doesn't support this feature. However the majority of YouTube Videos (especially older) do not play in Opera. I always get the message "An error occured. Please try again later".

In Contrast every Youtube Video works in Firefox, with and without flash. Opera seems not to support flash on Linux. It is a little bit annoying if you type in some keywords in the searchbar and almost every video won't play.

Version: 31.0.1889.174
Update-Stream: Stable
Operating System: Ubuntu 14.04.2 LTS (x86_64; X-Cinnamon)

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.155 Safari/537.36 OPR/31.0.1889.174

Please help me, I would love to continue using Opera since it has a slick and clean UI.

Thanks guys
