media.av1.enabled is true (default), the 'AV1 Demo by Mozilla and Bitmovin' appears blank, black.

… if I start in safe mode, load _and then_ reload the page, there's this, in the black box:

Some features are disabled by default unless you're building Nightly. AV1 is one of those, see
Try adding MOZ_OPTIONS+=--enable-av1 to Makefile.local under www/firefox, www/firefox-esr, www/waterfox, etc. I'm surprised Firefox is able to play any public AV1 video given its bundled libaom copy is from before bitstream format has been finalized.
Firefox 61.0_3,1: success.
Waterfox 22.214.171.124_1: fail (I didn't expect it to work, the media.av1.enabled boolean does not exist).

Turns out Mozilla is as guilty as Google in (ab)using *draft* standards in order to promote their browser.
<https://people.xiph.org/~tdaede/av1/akiyo_cif_short.webm> is more explicit (with Firefox 61.0.2,1),
> No video with supported format and MIME type found.
Firefox 63 enabled AV1 build by default but upstream is still yet to flip the pref. Obviously, AV1 on FreeBSD is not gonna benefit from sandboxing due to lack of Capsicum integration.
Bitmovin demo was also updated to work with Firefox >= 63.
