Thanks to all people involved, I just read about this new video format in the making/released [0].
Of course, I am not asking to support this, as this seems like the future, and not the present, but being a complete noob on video formats and codecs, I would like to know if someone more knolegeble has some insight about this and if it is something to keep in mind/someone has tested it and has experiences to share/client and vendor support? -- Jaime [0] <url: https://blog.mozilla.org/blog/2018/07/11/royalty-free-web-video-codecs/> On Fri, Jun 29, 2018 at 6:46 PM, Brion Vibber <bvib...@wikimedia.org> wrote: > Awesome sauce.
