Firefox is working on it, and enabling in Nightly 21:09:00 ... Safari's behaviour when they set the session to an ambient type, which allows mixing, and you call getUserMedia() it rejects with InvalidStateError 21:09:59 ... Discussed at TPAC, should it reject? Make a PR for getUserMedia()? Or change the audio session type 21:10:24 Chris: Apple folks not in the call today, it seems 21:10:34 Alastor: Any plans from the Chrome side? 21:11:04 Sangwhan: No plans, we'd want to see some large sites using it, then we'd reconsider. It's a matter of staffing 21:11:20 Alastor: I'm happy to share info as we progress with implementation 21:11:44 As of today, who uses this API? Anyone know? 21:12:03 Chris: You have an alternative proposal? 21:12:18 Alastor: No, just want to confirm the TPAC 2024 decision 21:12:29 ... I'll comment in the issue 21:13:09 Topic: Media Session 21:13:11 Chris: https://github.com/w3c/mediasession/issues/377 21:15:21 Tommy: If it's an enumerated set, you could have them as inidividual action handlers. I don't see how having a separate list of actions changes much 21:15:51 ... They seem to be looking for more control over the PiP experience, so maybe consider Document PiP instead? 21:19:28 Chris Looking at Media Session, more generally, we have a lot of open issues. Jan-Ivar raised #376 21:19:52 Tommy: On #376. we've tried not to overconstrain, so not sure what the right level to specify it would be 21:20:45 Chris: Let's organise doing a review of open issues 21:21:07 Topic: Media Playback Quality 21:21:17 Sangwhan: https://github.com/w3c/media-playback-quality/pull/30 21:21:59 ... I want to remove corruptedFrames. I did due diligence to check for usage. One is in Brightcove, we'll do some outreach there. And Yandex 21:22:34 ... It doesn't seem the information is used, so returning undefined should be OK 21:22:47 ... Marcos suggested returning zero, but we've been doing that for the last 6 years 21:24:14 https://chromestatus.com/metrics/feature/timeline/popularity/3117 is the usage data 21:24:29 ... It would be fine I think for us to remove from the spec 21:24:38 ... Safari is returning zero 21:26:01 ... I'll do the outreach. Yandex Advertising might be harder to contact. We can unship and see what happens 21:27:56 Topic: WebCodecs 21:28:08 TL:DR we want to bring WebCodecs to CR 21:28:17 Eugene: I want people to look through the WebCodecs issues that are marked as CR blocking 21:28:25 ... I intend to address those before TPAC 21:28:37 ... If people think something is missing, apply the tag more issues 21:28:46 CR blocking issue list: https://github.com/w3c/webcodecs/issues?q=is%3Aissue%20state%3Aopen%20label%3A%22CR%20Blocking%22 21:29:18 Chris: Thank you for progressing that 21:29:42 Eugene: I hope at TPAC to talk with Mozilla and Apple folks so they're happy with how the issues are addressed 21:31:37 availability: https://developer.mozilla.org/en-US/docs/Web/API/VideoDecoder#browser_compatibility (just VideoDecoder) 21:32:12 Chris: Will schedule an earlier meeting time, during week of August 31 21:32:30 Sangwhan: Does Mozilla have intent to ship WebCodecs on Android? 21:32:46 Alastor; I can find out from the engineers working on it 21:33:01 Topic: TPAC 2026 21:33:17 Chris: TPAC is 26-30 October 21:34:46 ... There's a planning issue in GitHub: https://github.com/w3c/media-wg/issues/62 21:36:30 Sangwhan: I'll dial in. I want to discuss trimming the Charter. Many specs could be ready for CR. Now's a good time 21:36:38 Chris: Sounds good 22:02:43 [Adjourned] 22:03:43 i/Alastor: For Audio Session/https://github.com/w3c/audio-session/issues/3 22:03:49 rrsagent, draft minutes 22:03:51 I have made the request to generate https://www.w3.org/2026/08/11-mediawg-minutes.html cpn 22:03:57 rrsagent, make log public
