AV1 support?

[DanielMcAssey]

Is there any plans to support AV1 codec, considering the bitrate benefits?

[alfredonodo]

I agree, nowadays the AV1 codec is very important, especially for very high resolutions, 2k+. The implementation of AV1 was part of GSoC 2022, but I don't know if anyone has implemented it.

@DanielMcAssey @alfredonodo if anyone has time to lend, see here: jitsi/jicofo#994

The code above was merged in, which I think means can signal the beginning of AV1 support for the video bridge.

This is just a small part that enables the signaling. The bridge still doesn't support it, but there's ongoing work.

Just keeping this up-to-date, two new PRs are being worked on:

• Support for video described by the AV1 Dependency Descriptor #1998
• AV1 rebased with jmt #1996

Hi,
any news about this?
Thank you

[darkBuddha]

AV1 support would be awesome !!

[alfredonodo]

Now we should be very close. Great.

Is there any umbrella ticket tracking what is left to do to offer support throughout the whole Jitsi stack?

From a brief look, it seems that full support is covered by #1998 and jitsi/lib-jitsi-meet#2350 (and these are both merged to master now).

If @JonathanLennox / @jallamsetty1 could confirm (?) I would definitely be happy to start some early testing :)

[jallamsetty1]

Yes, Av1 is fully supported in master with the exception of the case when a visitor (visitor mode that hasn't been released) joining the call doesn't support Av1.
The testing flag for the client side needs to be set - https://github.com/jitsi/jitsi-meet/blob/master/config.js#L88 in addition to the settings mentioned in this post - https://community.jitsi.org/t/how-to-enable-av1-codec/128518.
Happy testing!

[alfredonodo]

Is there any update on the release in the stable version?

[damencho]

That was already release in stable. You can enable it be following the steps above

[alfredonodo]

That's great. I thought there would be a blog post. Also, in theory it should be on by default and clients should negotiate the supported codec.

[jallamsetty1]

We will be enabling AV1 by default in the next stable. You will still have to set it as the preferred codec on your deployment. We plan to publish a blog post about it soon.

[outlaw-dame]

Do you have an idea how soon?

[damencho]

It is enabled now on meet.jit.si and the release candidate version that is deployed on meet is in our debian testing repo. And we will push the stable this weekend or on Monday with docker coming up soon after it.

There is nothing actionable in this issue, so I'm closing it.
If you see some issues ping us in the forum, thank you.
