#11383: Unable to achieve specified fps with AVFoundation camera on iOS

-------------------------------------+-------------------------------------
My goal was to stream 1080p at 120fps from the iPhone's main camera to a
local network server with minimal latency. However, I encountered issues
when trying to achieve the specified frame rates using AVFoundation. With
the BGR0 pixel format, I’m seeing around 57fps when the camera is set to
60fps mode, while with the NV12 pixel format, I’m getting 60fps as
expected in 60fps mode. The main problem arises with 120fps and 240fps
modes, where I’m only able to achieve between 70fps and 77fps, which is
far below the expected frame rates. Interestingly, with an earlier version
of FFmpeg, I was able to achieve just under 120fps in 1080p at 240fps
mode. Also of note, these tests were done on iPhone 14 Plus main back
camera, the application built using ffmegkit.
The expected behavior is to achieve the specified frame rate in the
corresponding frame rate mode using AVFoundation.
How to reproduce (change framerate and pixel format to reproduced the
results):
{{{
ffmpeg -f avfoundation -video_size 1920x1080 -framerate 60 -pixel_format
nv12 -i "0" -f null -
}}}
bgr0 1080p@60fps mode:
