Interesting - I've just checked the code and although buffers are set after port_format_commit when an instance of PiCamera is first created, they're not modified at all when the still...

Some interesting results from playing with this: Firstly, I think we're on the right track. I forced a few port encoding switches manually in picamera and watched the resulting buffer...

Many thanks for looking into this - what you've described is definitely the behaviour I'm seeing. I'll implement your suggested handling of buffer_num and buffer_size in picamera for 1.5. P.S....

I'll open a ticket on picamera to remind me to test this before the next release; I'm a bit busy with picraft (and dealing with a 2 month old!) at...

Sorry it's taken me so long to get around to testing this (she's now 10 months old!). The buffer_num_recommended fix has certainly changed something - it now resets to lower...

Good question -- I know jammy and noble both do, but you're correct that focal's still in the list (though if we're going to break keyboard on a release, I'd...

Yes, I'm afraid gpiozero and rpi-lgpio both assume gpiochip4 at the moment (which is almost certainly terrible laziness on my part, but the latter in particular has been a bit...

We're seeing a similar issue on Ubuntu ([LP: #2063365](https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2063365)), but I can also reproduce the appearance of the set chanspec messages on RaspiOS Bookworm lite on a Pi 5 powered...

It doesn't appear to be network-manager specific; I can reproduce the same messages with networkd in control of the interface, but it's notable in both cases wpa_supplicant is handling the...

Aha! [This thread](https://lore.kernel.org/all/[email protected]/T/) looks particularly relevant. Unfortunately it doesn't have a definite resolution (at the time of writing), but from a skim through I think it's describing this exact issue...
