So I have 2 Problems. Unreleated. But perhaps this thread can summarize it, because the information differs.
The current Linux Mint has adobe-flashplugin 11. Opera 25 doesn't recognize Flash.
Firefox says in about:plugins: /usr/lib/adobe-flashplugin/libflashplayer.so
Opera 25 says in opera://plugins/: Nothing.
How can I enable flash in Opera with my current setup? I heard something about pepper and something else but I haven't looked deeper in it. What does Opera 25 under Linux support and how?
Second: HTML5 Videos.
The current installation and the two installations before couldn't play HTML5 videos (youtube saying: error). I made a:
% cd /usr/lib/x86_64-linux-gnu/opera-developer
% ln -s /usr/lib/chromium-browser/libffmpegsumo.so
Works fine (I have no Chromium installed, only these ffmgeg stuff). Is it true, that Operas version of libffmegsumo.so is a bit broken? Is this above a thing to do? Or should it work without that hack?
Thanks in advance if you can answer some of my questions.
