Frigate card : no recorded video with IOS and with the Frigate card

1

Hello,
I have installed Frigate on a dedicated remote machine and I use the proxy on HA.
Everything works fine: I can read the videos recorded on the Frigate interface and with the Frigate card in HA on my PC, but I can’t play the recorded videos on the mobile application on IOS with the Frigate card.
I use a reolink camera.
Are there any parameters to set to improve this ? Do you have this issue ?
Here are my ffmeg parameters:

ffmpeg:
  hwaccel_args:
    - -hwaccel_output_format
    - yuv420p
