Bug 197703

Created attachment 369408 [details] iOS Safari 12.2 blurry/laggy webcam video Steps: 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. Source Code: https://github.com/webrtc/samples/tree/gh-pages/src/content/getusermedia/gum Result: 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). Expected Result: The frame rate should be at a normal'ish frames per second (I don't know, I guess 30 or above?). Additional Notes: 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. Environment: This reproduced on everyone's phone in the office that is running iOS 12.2. iPhone X (MQA52LL/A) iOS/Safari 12.2 Thank you!
