BUG: Video start delaying after iphone display rotated to horizontal

[imananoosheh]

Description of the Bug I'm facing

I have a fresh Raspberry Pi OS (64-bit) installed on Raspberry Pi 400
Device Info:
Raspberry Pi 400 | quad-core 64-bit ARM Cortex-A72 @ 1.8GHz | 4GB RAM
I have installed the Gstreamer libraries mentioned below and then I cloned and followed the instructions to build and run the rpiplay. it mirrors the iPhone screen fine in a vertical position but when it's rotated to a horizontal position (such as in YouTube) the video starts delaying and the below errors pop in the terminal mentioning this needs to be filed as a bug; so I did. Also CPU goes to the roof in this stage.

Note: Please let me know if any further details are needed.

It could be the OS bookworm has some compatibility issues. You could try it with OS Buster to see if that resolved the issue. Check out this post for more info:
