We are going to first implement this on Windows. “Real” support is dependent on 
driver support. If on your client machine, the camera app can do it, then this 
API can also do it.
I don’t have a Mac, but there’s platform 
support<https://bugs.chromium.org/p/chromium/issues/detail?id=1281408>, so we 
can collaborate once the initial Blink CLs lands.

Subject: Re: [blink-dev] Intent to Prototype : Background Blur API.


Thank you for starting this effort!

Quick question: Will this feature be supported on all six Blink platforms 
(Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Not just 
exposing backgroundBlur properties but also it "real" support.

Specification
https://w3c.github.io/mediacapture-extensions/#exposing-mediastreamtrack-source-background-blur-support
Summary

Background Blur API gives web developers a choice to use the native platform's 
API for background segmentation. Background Blur has become one of the most 
used features on Video conferencing apps like Teams, Meet, Zoom, Webex, etc. We 
want give Web apps similar capabilities as their native counterparts, 
leveraging the same platform APIs and to delight users without completely 
relying on ML frameworks like TensorFlow.js, Mediapipe, WASM libraries or cloud 
based solutions.

Motivation
A vast majority of communication these days happens on our client devices. 
During video meetings, participants are usually aware of how they look and what 
their environment (usually their home) is revealing to the audience. Most 
folks, especially ones without a dedicated office space would be inclined to 
hide messy rooms with pets and kids. Video meetings like face to face meetings 
are important for non-verbal communication but participants would rather focus 
on the important subject by removing the distractions in the background and 
prevent any accidental snafus. Microsoft 
says<https://www.microsoft.com/en-ww/microsoft-365/business-insights-ideas/resources/how-custom-backgrounds-keep-the-focus-on-you>
 in a 38 minute conference call, 13 minutes are wasted dealing with 
distractions and interruptions. Background Blur goes a long way to cutting down 
those disruptions. Zoom 
says<https://support.zoom.us/hc/en-us/articles/360061468611-Using-blurred-background>-
 "When a custom virtual background is unavailable or not suiting your needs, 
but you still want to maintain some privacy with regards to your surroundings, 
the blur background option can be a great alternative. This option simply blurs 
the background of your video, obscuring exactly who or what is behind you. It's 
great for hiding a cluttered dorm room, taking a meeting in a coffee shop, or 
just keeping things professional." . In fact, NCSC (National Cyber Security 
Centre UK) suggests using background Blur or a background 
image<https://www.ncsc.gov.uk/guidance/video-conferencing-services-security-guidance-organisations>
 for staff meetings to add a degree of personal privacy.
On the Web, due to a lack of a standardized API for Background Blur and 
widespread demand, developers have no options but to use ML frameworks like 
Tensorflow.js and other WASM libraries to satisfy their customers. This 
Background Blur API gives developers a choice to use the native platform's API.

WebKit: No signal but Apple co-author of explainer / PR. 
https://lists.webkit.org/pipermail/webkit-dev/2022-June/032311.html

Web developers: No signals

Other signals: Almost every video-conference app has background blur feature.

WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that it 
has potentially high risk for Android WebView-based applications?

Debuggability

Is this feature fully tested by 
web-platform-tests<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
Yes ( as part of CL )
