**Description of problem, include YAML if issue is related to notifications:**

I want to attach a video in a message. I use this code to create a video when the front door opens and the alarm is on.

```
- service: camera.record
target:
entity_id: "camera.grovkok"
data:
filename: '/media/cctv_grovkok/video.mp4'
duration: 30
```
That works perfect and I get a video when I trigger it. Then I use this code to send the video to my android phone. I have a delay so the video will stored.

```
- delay:
seconds: 59
- service: notify.mobile_app_pixel_6_pro
data:
message: Någon kom in
data:
url: "/lovelace/camera"
priority: high
video: '/media/local/cctv_grovkok/video.mp4'
```

I get the message but no video. The logg shows this.

```

If I [convert the video on the internet](https://video-converter.com/) and put I back in the same folder and trigger the automation I get the video in the message. I converted the file from mp4 to mp4. Logg show this.
