Camera.record creates video but cannot attach to Andriod notifications

The camera.record is records a video that is still viewable ut cannot be used as a standard attachment for the notify command. Other videos saved can be seen but the recorded
videos using camera.record do not work. Thanks in advance.

Update: converted recorded .mp4 video to .mp4 using online converter and uploaded to home assistant and it worked. So problem must be the original .mp4 video creation from camera.record

I had the same problem and after I converted the mp4 file to mp4 I got it to work.

Did you find any solution to fix this?

Any idea? @dshokouhi
