I am using openSUSE Leap 42.2 and Opera 46.0.2597.57.

Some videos on the internet (maybe the half on YouTube) do not work on Opera.
YouTube tells me that I cannot watch the video and suggests me visiting https://www.youtube.com/html5.
H.264 and MSE & H.264 are not supported by my browser as the page mentions, although Opera is listed as suported.

I did some research and installed the following packages (which were not the sollution):

• chromium-ffmpeg-extra


• chromium-ffmpeg-extra-debuginfo


• chromium-ffmpegsumo

Maybe I need to mention that Firefox works pretty fine with YouTube and other videos that do not work on Opera.

Thanks a lot for your help.

PS:
If this issue is fixed with openSUSE Leap 42.3 this would be an option for me, but I still hadn't enough time for an update.

This unfortunately is a known problem in Opera spanning to OpenSuse 42.3. YouTube reports that H.264 and MSE & H.264 both are unsupported when accessed from that OS. This is using Opera 46.0.2597.26, not quite as fresh as yours, but newer OS.

Looking around the web, there is reference to a Chromium codec patch. Uninstalling Chromium makes no difference on my setup, nor force reinstalling ffmpeg after uninstall of Chromium's extra codecs. For those not feint of heart, there is a manual-linking solution [1] involving libffmpeg.so, which seems to have success there (but must be redone each time Opera is updated). I have not tried the manual linking.

I had same issue on Fedora 27, so I followed the instructions provided in link by @doug0 and tried out libffmpeg prebuilt with proprietary codecs. Here is essentials:

• go to https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases


• copy link to latest release (in my case 0.26.6)


• close Opera browser


• 
  

  open terminal, and enter the following:

  
  
  

  $ curl -L -O https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases/download/0.26.6/0.26.6-linux-x64.zip
  $ unzip 0.26.6-linux-x64.zip
  $ sudo mv libffmpeg.so /usr/lib64/libffmpeg_h264.so
  $ sudo mv /usr/lib64/opera/libffmpeg.so /usr/lib64/opera/libffmpeg.so.orig
  $ sudo ln -s /usr/lib64/libffmpeg_h264.so /usr/lib64/opera/libffmpeg.so

Another option is to install the snap version of Opera (https://snapcraft.io/opera) this worked for me

You can check your browser id at opera://about/ and download proper libffmpeg.so version from http://ppa.launchpad.net/saiarcot895/chromium-beta/ubuntu/pool/main/c/chromium-browser/.

For example my browser id is "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36 OPR/56.0.3051.52" and I need libffmpeg.so from chromium-codecs-ffmpeg-extra_69.0.3497.72-0ubuntu1~ppa1~16.04.1_amd64.deb .
You should extract and replace (with backup) libffmpeg.so in your opera directory(in Debian /usr/lib/x86_64-linux-gnu/opera/ ) and restart opera.

mkdir /tmp/libffmpeg
cd /tmp/libffmpeg
wget http://ppa.launchpad.net/saiarcot895/chromium-beta/ubuntu/pool/main/c/chromium-browser/chromium-codecs-ffmpeg-extra_69.0.3497.72-0ubuntu1~ppa1~16.04.1_amd64.deb
ar x chromium-codecs-ffmpeg-extra_69.0.3497.72-0ubuntu1~ppa1~16.04.1_amd64.deb
tar xJvf data.tar.xz
sudo cp -b ./usr/lib/chromium-browser/libffmpeg.so /usr/lib/x86_64-linux-gnu/opera/
