FFMPEG on Ipad 4

Hi have an old Ipad 4 that I wanted to repurpose as a wall mounted tablet. The issue is with my FFMEG vidéo feed. I am using the latest version of Home Assistant and using the Entity Card to display the Vidéo Feed.

I have no issue on more recent devices but the iPad 4 wont display the video feed. See the attached screen capture:

My “Simple thermostat card” are also in error which is not a big deal but might be related…

Does anyone know the what is the limitation the prevents the iPad from displaying the video feed ?

You may need to make sure this works with what kind of video the iPad 4 supports.

You pointed me in the righ direction. The video encoding is not the issue. Comparing the specs of the iPad 4 with newer generations I realized the the max supported resolution is 1080P on the iPad4.

So, adjusting the vidéo feed resolution fixed the display issue.
