--- Comment #3 from Trung Le <ldttmt at gmail.com> ---
I have been able to reproduce this issue with just use navigator.mediaDevices.getUserMedia() and applyConstraints() API.
Repo steps:

- Call stream = navigator.mediaDevices.getUserMedia({ video: { deviceId: { exact: <deviceId string> }}}); <- exact here works.
- Call stream.getVideoTracks()[0].applyConstraints({ deviceId: { exact: <deviceId string> }}); <- throw OverconstrainedError error in Safari 15 but not Safari 14.
