Thanks for the great hint. It works line charm. Here are the steps that what I've done:

1. run Opera, click "about" and scroll up to look for the install path. Here: /usr/lib/x86_64-linux-gnu/opera, then run: killall opera
2. cd /usr/lib/.../opera
3. sudo mv libffmpeg.so libffmpeg.so_original
4. snap install chromium-ffmpeg
5. cd /snap/chromium-ffmpeg/current/
6. look for the most actual version:chronium-ffmpeg-XXXXX. Here: chromium-ffmpeg-108372//chromium-ffmpeg
7. sudo ln -sf /snap/chromium-ffmpeg/current/chromium-ffmpeg-108372/chromium-ffmpeg/libffmpeg.so libffmpeg.so

Finish. Start opera Opera, goto www.bbc.com and try with any REEL video....to see if it might work and...it works!

hi,
I have noticed that Opera on Linux (Mint cinnamon 21.1) has problem with videos of BBC (e.g. REEL) or CNN (e.g. news) and shows a weird error code.
Because Firefox won't have this problem I believe that it must be an Opera bug.
