"ioctl(ret=-1, errno=22): Can't queue buffer." with v4l2 camera interface #85

Open CelloVerb opened 1 year ago

CelloVerb commented 1 year ago

Looking for help and suggestions:

libcamera streaming works properly with camera-streamer, but v4l2 doesn't, and gives "ioctl(ret=-1, errno=22): Can't queue buffer." when trying to start capture. Am wanting that very low latency with v4l2. I don't see any errors on stdout with v4l2 startup.

Hardware: raspberry pi zero W System: Raspbian GNU/Linux 11 (bullseye) / 11.6 Camera: Arducam imx219 8MP

Any suggestions for what would cause this, or other places to look?

Thanks for starting this great project and filling this niche! Cello

OK, I've dug further and realized that disabling the media-controller interface in /boot/config.txt fixes this - changing dtoverlay=imx219 to

But now I can't use libcamera apps - is there a way to have both?

same issue while use camera-streamer in Docker container... But I don't know how can we fix /boot/config.txt in any image? I'd try to use that images: balenalib/rpi-raspbian:latest, balenalib/raspberrypi4-64-debian

It's not possible to have both the legacy camera stack and the libcamera stack configured at the same time. It would probably be more beneficial to look at how to lower the latency with libcamera.

I could envisage a low latency mode in libcamera being implemented. I think at the moment libcamera on RPi prefers extra buffering to ensure there is no loss of data over a leaky but shorter pipe.

Ultimately that's a design choice by Raspberry Pi in the RPi pipeline handler presently, but could be configurable.
