@lukeharrison1122 is it still working? even in desktop mode opera still stop yt background video for me.

@arpy2w not true.
even in desktop version of youtube.com forced in opera via 3 dots it still stop playing when window is minimized, switched tab or just off the screen.
Other chrome based browsers don't have this problem.

Opera please allow us to play background yt!

Why it works on FF and not on Opera ?
Do FF buy license for h.264 ?

I was trying woth another repos including that one. As far as I see they only update ffmpeg binary, but not other libraries like libavcodec that is needed by opera and in final it still doesn't work.

Yes, it looks like this is the source of problem. Version of ffmpeg library.
I have on my linux mint (most popular linux distro) version 2.4.3 and only latest ubuntu has never one.
There is no way right now to install next versions on mint.
Is there any chance to make next betas to be compatible with ffmpeg 2.4.3 or when do you plan to release stable (which I hope will remain to be compatible with 2.4.3) with sidebar support ?

thanks

hi Guys, we need sidebar from beta and working webm (h264 video) as in stable.

I have more news. Following that tutorial I have installed another ffmpeg library:

http://www.webupd8.org/2014/12/how-to-get-flash-and-h264-to-work-in.html

now pera stable works fine, opera beta has sound but black screen, opera developer crash.
The point is that opera stable doesn't have sidebar, so I need beta or developer.

Any idea why they have might have issues here ?

After some research now I know that those videos are 'webm' types. They play well in all browsers except Opera.

it seems like file library responsible for that format is in Opera's folder and it's names libffmpegsumo.so

I have tried to replace that file with the one from chromium folder like in first post here:

https://forums.opera.com/topic/4627/can-you-summarize-for-me-opera-25-under-linux-with-flash-and-html5-videos

but that only craches Opera on opening that page.
It seems like Opera has broken that lib and I don't know how to fix it.

I have flash player installed via Pepper Flash Plugin package in Mint Linux.
All flash based websites like youtube etc. work without problems.

Your opera is playing that twitter video using flash player ? Maybe i have to install some additional codecs in my Linux ?

Hello,

I just installed both stable and developer versions on mint linux. I have working flash player, but there are some websites where video doesn't start on Opera, while it works on Firefox and Chrome/Chromium.

Here are two exaple websites:

Does anyone know what could be a reason ?
