+1
Error raises on closing a camera window.
There's already an open issue #14919

[jiriteach]

+1 rpi_camera no longer works throwing this error.

[xcray]

remains on 0.72.1

[xcray]

since #14919 is already there, this issue should be closed, I think.

Hi,

I still have this error when running Hass.io 0.73.1.
Error output:

Traceback (most recent call last):

This in my configuration for MJPEG:

I had this error on 0.74 with ffmpeg cameras (three different ones). Now, with 0.75 there is no longer error in log, but when I click the picture to view video, nothing is shown. Just a title with camera name but no video.

Maybe open a new issue as this one is closed already ?

This issue should be fixed in 0.75 (#15577). Anyone still experience similar problem, please open a new issue with all detail information.

I am going to lock this thread.
