I just installed Ubuntu 16.10 but it cannot play some videos from Twitter in Firefox. Instead, I get a message, something like
This media cannot be reproduced.
If I open the Firefox console, I see this message:
The video on this page can’t be played. Your system may not have the required video codecs for: video/mp4; codecs=”avc1.42E01E mp4a.40.2″
Answer
The solution is straightforward: just install ffmpeg:
sudo apt-get install ffmpeg
