web browser #html5 audio and video #codec problems (@LondonRealTV)
web browsers (chrome, chromium, edge, firefox, opera, safari) that support html5 should be able to natively play audio and video however you can only guarantee that open www codecs / formats will work such as OGG & WEBM and NOT MP4 or VP8 or VP9
(some sites such as https://londonreal.tv/ wont play videos until you fix these settings)
mozilla firefox has a separate plugin for openh264 (https://www.openh264.org/) that is enabled by default on some distros and not others
for example on oracle unbreakable enterprise linux 7 (and red hat 7 ? and centos 7 ?) the openh264 is DISABLED by default
- run firefox
- click preferences
- click extensions
- click plugins
- locate openh264 (disabled)
- click the … icon
then chose always from the following 3 options
