Video input device doesn't support the value passed for constraint '' in iOS 14.3

[jay-supakorn]

Describe the bug we build 1:1 video communication application base on OpenVidu example application version

• ionic version 5
• angular version 9

Occasionally, after upgrade iOS 14.1 to 14.3 we found problem on initPublisherAsync on below.

publisher = await this.OV.initPublisherAsync(undefined, {
        audioSource: this.localUser.getAudioSource(),
        videoSource: this.localUser.getVideoSource(),
        publishAudio: this.localUser.isAudioActive(),
        publishVideo: this.localUser.isVideoActive(),
        mirror: this.platform.is("android")
          ? !this.localUser.isBackCamera()
          : this.localUser.isBackCamera(),
      });

Console :

Hi @moqshosting ,

This could be related with this iosrtc issue https://github.com/cordova-rtc/cordova-plugin-iosrtc/issues/618#issuecomment-748620749

@moqshosting @CSantosM Im having the same issue witho openvidu-ionic-call. I updated the package to include the latest release of iosrtc in package.json and still no luck. Let me know if you all have any troubleshooting advice or if theres is anything i can do. I will also continue troubleshooting

[AustinRSellers]

It ended up being iosrtc 6.0.16. Just upgrade to 6.0.17 and everything should work.

For newer ios versions (>14) you need this cordova iosrtc no longer. It works out of the box with ionic
