iOS Safari 12.2 blurry/laggy webcam video
On an iPhone X running iOS 12.2, open Safari.
Go to https://webrtc.github.io/samples/src/content/getusermedia/gum/
Click the "Open camera" button.
Click "Allow" on the permission modal dialog.
The camera frame rate seems to be slow and the camera capture rate seems to be slow causing blurriness in the video and making it a bit harder to get a sharp picture if using this as a preview for a selfie capture (which is what I am doing).
The frame rate should be at a normal'ish frames per second (I don't know, I guess 30 or above?).
Task switching away from Safari and back, makes the video play at a high frame rate again, but the video now has black bars on the sides.
This reproduces on another project I am working on that is using a very similar code path.
This reproduced on everyone's phone in the office that is running iOS 12.2.
iPhone X (MQA52LL/A)
