Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, enhancement, P3)

Description

[Bryce Seager van Dyk [:bryce] (he/him) - Not reading bugmail]

Starting with Widevine CDM 4.10.1582.2 we should have AV1 support in the CDM and need to plumb the correct info to it as well as surfacing support to the web.

Hi,

We're interested in adding AV1 support for our video delivery and I was wondering if you have a timeline for supporting encrypted AV1?

Thanks

We don't have a specific date at this time. More backend work is required in Gecko, though some has already taken place. Do you have a specific time frame you're targeting?

If you expect to have a test stream available, that would be useful for testing and ensuring compat as this is implemented.

If you'd like to discuss more via email, please email at the email on my bugzilla profile. I'm happy to discuss here, but longer discussions can make bugs hard to follow down the line.

Unassigning bugs assigned to Bryce because he no longer works at Mozilla.

Does bitmovin currently use encrypted AV1? How commonly used is it?

Hi Jeff, We (bitmovin) do support it. Still fairly limited use right now, but think it will be needed for SVOD services/Hollywood content in the near future. We can provide some samples if that would help.

Yes, please.

Given some demo site where I can verify my patches and Bryce's work in bug 1643410, I would be happy to finish up the work needed for this.

Attachment: Bug 1601817 - Add plumbing to expose Widevine and Clearkey AV1 support.

This patch adds in the necessary plumbing to allow attempting to use the
Widevine plugin for EME decryption with AV1 codecs.

This will load it the Bitmovin player, but you can copy the manifest and drm server if you want to test anywhere else.

Thank you very much! I was able to fix the missing bits from my patches, and get this working.

Did you want to nominate this for the Fx125 relnotes? Please set the relnote-firefox flag to ? if yes.

Comment 19

[Alastor Wu [:alwu]]

Yes I think this is something worth to mention in the release note.

Release Note Request (optional, but appreciated)
[Why is this notable]: Added another new video codec format which can be used in the encrypted playback, so the video content provider can start use that newer and better codec on streaming.
[Affects Firefox for Android]: Yes
[Suggested wording]: Firefox now supports AV1 codec for Encrypted Media Extensions (EME).
