Background filters are lost when user turn off camera

[Vondry]

Which package/packages do you use?

• @stream-io/video-react-sdk
• @stream-io/video-react-native-sdk
• @stream-io/video-client

Describe the bug
When user selected background filter image or blur and then turn off camera (using camera.toggle() from useCameraState), then background filter are lost and user has to go and setup it up again from the begining.

To Reproduce

1. Setup any background filter (image or blur) using useBackgroundFilters()
2. Turn off camera using camera.toggle() from useCameraState()
3. Turn on camera using camera.toggle() from useCameraState()
4. Observe that filters from 1. step are lost

Expected behavior
I would expect that background filters (image or blur) are preserved during camere toggling.

Version

• "@stream-io/video-react-sdk": "^1.27.1"
• "@stream-io/video-filters-web": "^0.5.0"

Hi @Vondry, thanks a lot for reporting this! I tried to reproduce the issue on my side, but everything seems to work as expected, the filter should automatically reapply when the camera is enabled again, unless it was unregistered in the meantime.

Could you please try to reproduce it here: https://getstream.io/video/demos/

If it still happens, a small sandbox would be super helpful so we can look into it properly. Thank you!

Hi @jdimovska I was able to reproduce the issue with losing bg filter (blur in the video) also in the https://getstream.io/video/demos. Same error happens also for me locally in my app.
