CircularOutput() limitations ...

[lmitcham]

My project is using a Raspberry Pi Zero 2W and a Picamera HQ. My OS is Bullseye and I am using Picamera2. I am not having any issues except when I ask for a circular buffer of less than 10 frames, to store video prior to a triggering event.

I am using the CircularOutput() routine to capture a single, or just a few frames, of video. However, it appears that 6 is the minimum number of frames that the engine can process consistently.

Is there in fact a limitation of the CircularBuffer()?

Thank you,
