But Safari says this is overconstrained even though it can do e.g. 640x480 which would satisfy it. In fact being explicit about ideal fails in the same way: { video: { width: { ideal: 320 } } } Tested on Sierra + Safari Beta, Sierra + Safari Tech Preview 38, and iOS beta 9 + Safari. 1374107 1 adam 2017-11-21 15:48:06 -0800 This seems to be resolved now actually. Can't reproduce this issue anymore. 1377281 2 ben.browitt 2017-12-02 06:55:12 -0800 GUM with video constraints still fails on iOS 11.2. 1379263 3 martin.hejral 2017-12-07 13:42:57 -0800 I confirm this bug. There is test pen https://codepen.io/hejral/pen/eeaKrx?editors=1011 which works, and another which do not https://codepen.io/hejral/pen/RjzovG?editors=1011 And yes, with "playsinline" this works also for iPhone ;-) With no playsinline this works everywhere else. I must agree with comment "The fact that you need to add playsinline is still a bug." 1379268 4 martin.hejral 2017-12-07 13:51:28 -0800 WebRTC demo with | constraints = { video: { width:320,height:240 } } output is: mediaDevices: Error -> Invalid constraint see also: https://bugs.webkit.org/show_bug.cgi?id=176843 1458057 5 adam 2018-09-09 16:51:29 -0700 This is now only happening for me on iOS, not on Mac OS.
