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

Why is this being removed? It's an essential feature and works great. Use case: pitchable DJ-player style use, akin to how a record player works. All browsers should implement it.

It is a proprietary feature with no known plans from other vendors to support it (certainly not with a "moz" prefix). If there's a reason to assume that this will be specified and other browsers will implement it unprefixed, we'll probably add the unprefixed API before removing the prefixed one, though.

This came up today again in the AudioWG, with valid use-cases. Not that it's hard to re-implement if removed.

Context: https://www.w3.org/Bugs/Public/show_bug.cgi?id=15318 (rejected in 2012 for inclusion in HTML), but https://github.com/whatwg/html/pull/3881 is a non-merged but accepted PR on the subject. It's "just" missing tests.

In the meantime, I agree that we certainly should get rid of prefixed APIs, maybe simply un-exposing it from the web. Best to start with a telemetry probe.

I'm working adding preservesPitch in Chromium, un-prefixed.

[Philip Jägenstedt [:foolip]]

The unprefixed variant has shipped in Chromium 86, and bug 1652950 is about unprefixing this in Gecko.

Closing this, because it's now standard. We'll un-prefix in bug 1652950, as Philip said.
