Add VP9 codec support to JVB 2.0

[erotavlasme]

Hi,
it would be very important to add VP9 codec support to jitsi-meet as discussed here. There is already a patch for old JVB 1.0 and a developer is available to adapt it.
Right now, the VP9 codec support would allow to close the gap between jitsi and its competitors.
Thank you

Dear sir:
Which version of jvb1.0 supports vp9? How can i enable vp9
Thanks!

We would love to support vp9 in jitsi-meet, and it is on our roadmap. But note that the PR in libjitsi meet is just one small step, and full support will require a more substantial effort.

[erotavlasme]

Any idea about the release date? It would be very useful right now.

VP9 is really important to bring down bandwidth requirements.

[daynis-olman]

Do we know when we can expect an alpha release for this?
Really excited this is being implemented! This will be a game changer, and really put JITSI Meet on the map.

In jitsi-media-transform a draft PR is opened to enable VP9: jitsi/jitsi-media-transform#258

Also, not sure you all are following this thread but it seems the community can help quite a bit but feels ignored and is losing motivation to help. @JonathanLennox I believe you're working on this. Perhaps you can take a look and give Syonyk some feedback?

Good luck and thanks

With support in Safari on macOS and iOS VP9 seems to work on all relevant browsers. So VP9 could actually be the default codec by now.

Isn’t it (unfortunately) already the default since JVB 2.1-358-g3abd64a9-1? At least about:webrtc in Mozilla Firefox showed something like this.

So the issue about implementing support could be closed?

Anyway, I strongly advice against using VP9 by default, as older hardware with no VP9 hardware acceleration suppord (and often only H264 and VP8 hardware acceleration support), will have a lot of trouble to decode several VP9 streams.

[bbaldino]

VP9 definitely isn't the default codec anywhere. The VP9 PRs in the bridge/JMT haven't been merged yet.

[alfredonodo]

Hi,
any new about this important feature? Now it should be merged.

[damencho]

The support for VP9 landed few weeks ago in jvb2.

[paulmenzel]

I could have sworn VP9 was used already with the unstable packages (deb https://download.jitsi.org unstable/) before submitting that merge/pull request. At least that is what I gathered from the browser developer tools and the system load.

Besides that, in my experience, I still prefer VP8 (or even H.264), so old devices can use GPU hardware acceleration for decoding (and even encoding).

(Looks like I already commented that in October 2020. No idea, what I did wrong in my testing.)
