OVP 2.22.0 - Switching between back-camera and front camera does not work on few or most Android mobiles, whereas it works well on iPhones #751

Describe the bug We recently upgraded from OVP 2.17.0 to OVP 2.22.0. Switching between back camera and front camera was working as expected in OVP 2.17.0 on all Android and iPhone devices.

Expected behavior In OVP 2.22.0, when switching from back camera to front camera and from front camera to back camera multiple times, streaming should be seamlessly done by the selected camera.

Wrong current behavior Since the upgrade to OVP 2.22.0, switching between back-camera and front camera does not work on few or most Android mobiles, whereas it works well on iPhones. We use the creation of new publisher approach to switch the camera.

Our web app streaming functionality works well when loaded for first time. It gets hold of the back camera as default and does the live streaming. When we switch camera from back to front for first time, streaming works well with front camera, but when we switch again from front camera to back camera, it does not work.

It stops the streaming and shows the default UI, when again switching the camera it starts streaming from front camera. So, once it captures the front camera it does not switch to back camera again, but front camera works well every time we switch camera.

OpenVidu tutorial where to replicate the error OpenVidu demo portal does not have switch camera capability, so unable to reproduce the issue there. However, on CE development container and as well as OV Professional, we were able to produce the issue with below steps:

  1. Load the back camera of mobile and do live-streaming by using Samsung M30.
  2. Once the streaming is established, switch to front camera.
  3. When streaming is established, again switch to back camera. This will not work.
  4. Again switch to front camera, and it works again with front camera.
  5. Switch to back camera again, it will not work, and this behaviour continues.

Did you check that your openvidu-browser dependency is in the same version as OpenVidu Server?

mallikarjungurav commented 2 years ago

Yes we reverified the openvidu-browser dependency and OpenVidu Server and our backend server dependencies. All are at 2.22.0. Moreover, camera switch works well with iPhone devices and few of the android devices but it is not working on few of the android devies as listed in Client Device Info section.

@cruizba Any finding on this issue please?

cruizba commented 2 years ago

I am thinking that maybe this is related with this similar issue: https://openvidu.discourse.group/t/issue-when-switching-cameras-on-specific-android-devices-device-already-in-use/4185/4 , the person on the issue managed to solve a similar issue.

Also, we have demo here https://demos.openvidu.io/openvidu-call/ (OpenVidu Call) which let you change the camera while in a session. You can check it there if you want.
