Mediastream Image Capture
Image Capture API specifies list point of interests, where each point (it seems) is responsible for running 3A algorithms. All other OS platform APIs allow to specify POI / area...
The spec is not very clear about how PTZ permission is asked as part of the getUserMedia call. It would be good to identify how this is supposed to work...
Would be useful if the `ImageCapture` interface was `[Transferable]`, as this would allow offloading grabbing frames from the main thread. Trying to grab frames on the main thread is always...
The current implementation of `ImageCapture.grabFrame` in Chromium will always wait for the next frame from the video stream, which was unexpected. The spec doesn't say anything about timing, but I...
The current Chromium implementation of `grabFrame` waits until a new frame is available before resolving, which means if `frameRate` is 1, it may take up to 1 second for the...
The current Chromium implementation will reject `grabFrame` for a muted stream, [here's the relevant line](https://cs.chromium.org/chromium/src/third_party/blink/renderer/modules/imagecapture/image_capture.cc?l=43). The spec currently says nothing about rejecting on a muted stream. This behavior is problematic...
AFAIK there is no way to control the power line frequency of the video capture device to reduce the light flickering. The idea would be to add a new `powerLineFrequency`...
Hey 👋 I kind of accidentally stumbled across the Image Capture API and I'm amazed by the amount of controls that are technically available. However I wonder if there's somewhere...
It is possible for a camera to have the capture permission enabled, but PTZ disabled. In this case the PTZ capabilities should not be exposed. Once PTZ permission is given,...
While the current W3C [Media Capture and Streams API](https://www.w3.org/TR/mediacapture-streams/) and [Media Capture Image API](https://w3c.github.io/mediacapture-image/) allow control over certain camera properties such as exposure, ISO, and focus distance, they lack the...
