On: It's time to replace GIFs with AV1 video

[simlevesque]

The article claims that AV1 works since FF 65 but the examples do not work on FF 66.

64-bit Windows users only, according to the release notes. https://www.mozilla.org/en-US/firefox/65.0/releasenotes/

Edit: as ataylor pointed out, Mac support was added in 66.0 https://www.mozilla.org/en-US/firefox/66.0/releasenotes/

Confirm, doesn't work for me on FF on Windows.

And this is a challenge for a "new" format: if AV1 works on 90% of systems, and GIF works on 100%, then in many cases GIF is the clearly correct solution. Why would I throw away 10% of my money? Why would I ignore 10% of my customers? In many businesses, just a few customer calls because of this could seriously hurt profitability.

The article shows how to make a fallback that serves GIF in cases where AV1 is not supported. That saves you 90% of your bandwidth for 90% of your image loads.

Set `media.av1.enabled` to true in about:config.

That worked for me on Linux FF 66. Thank you.

Are you on Linux? https://caniuse.com/#feat=av1 says that FF 66 has it enabled by default only for Windows and macOS users.

I'm on Firefox 66 on Mac and the last couple AV1 videos don't play.

[milansuk → simlevesque]

I'm running Chromium 73 on Debian 9 and AV1 examples also don't work.

edit: I've downloaded first example[1] and video player won't play it neither.

edit2: Firefox 66 works!

Thier claims about encoding working in ffmpeg are also untrue..

Author here: Can you clarify this?

Can also confirm does not work on firefox 66 for me; chromium does work though.

[matthberg → simlevesque]

Odd, it's working for me:

Firefox 66.0.5 (64-bit)

on Windows 10
