Raspberry Pi ZeroW Camera Focus with libcamera-vid

Several years ago I was trying to play with a camera on a Raspberry Pi Zero and was using FFMPEG to stream video to my PC. Now that I’m trying out the Bullseye release of Raspian, I’m attempting to use the camera tools that are installed by default.

I’ve got an Arducam with 160° lens connected to my Pi Zero.

pi@WimPiZeroCamera:~ $ libcamera-vid --list-cameras
[0:01:26.600607679] [701]  INFO Camera camera_manager.cpp:293 libcamera v0.0.0+3544-22656360

0 : ov5647 [2592x1944] (/base/soc/i2c0mux/i2c@1/ov5647@36)
    Modes: 'SGBRG10_CSI2P' : 640x480 1296x972 1920x1080 2592x1944 

First I ran the previous command to see that the camera is recognized, then I run the following command to set up the port on the Pi. The program produces no output in the terminal until I connect from my PC.

pi@WimPiZeroCamera:~ $ libcamera-vid --timeout 0 --nopreview --listen --output tcp://0.0.0.0:5000

On the PC, I run VLC

Open Network Stream
tcp/h264://192.168.0.63:5000
View from the camera

looking back at the console output, you can see that it’s defaulting to 640×480 resolution.

When I stop the video on the PC, libcamera-vid exits on the Pi.

I can specify the width and height of the output at the Pi, but it seems to be having problems delivering data.

libcamera-vid --timeout 0 --nopreview --width 1920 --height 1080 --inline --listen -o tcp://0.0.0.0:5000
the video starts, but rapidly freezes.

I’m including the output of dmesg here in case anyone has a solution to my problem. Most likely I’m going to switch back to the Buster release of raspian and see if everything works properly there.
