H.264 videos work on my machine now! Found my solution here: https://forums.opera.com/post/122456

Besides, I had to replace libffmpeg.so becuase youtube said, my Opera didn't support h.264, so I downloaded opera-ffmpeg-codecs-58.0.3029.81-1-x8664.pkg.tar.xz from repo.herecura.eu/herecura/x8664/... and now everything is all right!

Thank you so much for pointing that out! I am finally able to play h.264 videos with opera on my fedora machine!

@jimunderscorep do html5 videos work on your machine?

I installed the chromium-media-libs package on fedora and had to change the path in the ffmpeg_preload_config.json from lib to lib64:

cat /usr/lib64/opera/resources/ffmpeg_preload_config.json 
[
  "lib_extra/libffmpeg.so",
  "/usr/lib64/chromium-browser/libffmpeg.so",
  "/usr/lib64/chromium-browser/libs/libffmpeg.so"
]

find / -name libffmpeg.so 2> /dev/null
/home/wadka/.local/share/Trash/files/libffmpeg.so
/usr/lib64/chromium-browser/libffmpeg.so
/usr/lib64/electron/1.3.13/libffmpeg.so
/usr/lib64/opera/libffmpeg.so

So everything should work, but it still doesn't...

reason is wrong location

Did you manage to get it working? I added the lib64 paths after installing chromium via dnf but it still won't play h.264 encoded videos...
