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?

Current state on this:
- still hoping to deploy the libvpx+ffmpeg backport first so we start
with
best performance; Moritz made a start on libvpx but we still have to resolve ffmpeg (possibly by patching 3.2 instead of updating all the
way
to
3.4)
I've completed this today. We now have a separate repository component for stretch-wikimedia (named component/vp9) which includes ffmpeg 3.2.10 (thus allowing us to follow the ffmpeg security updates released in
Debian
with a local rebuild) with backported row-mt support and linked against libvpx 1.7.0.
I tested re-encoding
Pitts_Todeswand_2017_-_Jagath_Perera.webm
(which is a nice fast-paced test file) from VP8 to VP9, which results in a size reduction from 48M to 31M.
When using eight CPU cores on one of our video scaler servers, enabling row-mt gives a significant performance boost; encoding time went down from 5:31 mins to 3:36 mins.

Cheers, Moritz
