I can confirm that the issue remains, at least in my case, in current version.

I have an automation that records 15 seconds. Since yesterday I have the error Call-service API error. Error Message: Stream already recording to /config/www/images/security/casa/video/casa_video_20200916_145343.mp4!

So the message is several hours old. There is no such file in the folder, so it seems the recording has failed and it thinks it is recording.

This is not the first time I have this error. The only way to make it work again is to reboot the system.

Out of curiosity, did any of you have a RuntimeError: dictionary changed size during iteration error message from in your logs? It could cause this, as the worker thread will stop without closing the stream outputs. If that’s the case, #38766 may fix the issue.

Would prefer to have a camera.record_stop and camera.record_start service. In that way you get more control. The default 30 sec recording can still be applicable but can be overruled by a camera.record_stop service… I also face the issue that although I programmed a duration and lookback period that the record doesn’t finish and blocks any new records until I turn off and on the automation

Still happens with Home Assistant 2022.3.5 Once the record stuck it fails with the error when you trying to record again and it says: Stream already recording to /media/camera/latest_motion_salon.mp4! Please advise what is required for the further debug.
