Hello.
I have raspberry compute module 4 with connected camera.

 rpicam-hello --list-cameras
Available cameras
-----------------
0 : imx708_wide [4608x2592 10-bit RGGB] (/base/soc/i2c0mux/i2c@1/imx708@1a)
    Modes: 'SRGGB10_CSI2P' : 1536x864 [120.13 fps - (768, 432)/3072x1728 crop]
                             2304x1296 [56.03 fps - (0, 0)/4608x2592 crop]
                             4608x2592 [14.35 fps - (0, 0)/4608x2592 crop]

Debian GNU/Linux 12 (bookworm) with
Linux raspberrypi 6.12.20+rpt-rpi-v8 1 SMP PREEMPT Debian 1:6.12.20-1 rpt1 bpo12+1 (2025-03-19) aarch64 GNU/Linux.
On this version legacy camera stack is disabled. So baresip cant use /dev/video0 device.

_libcamera is a new software library aimed at supporting complex camera systems directly from the Linux operating system. In the case of the Raspberry Pi it enables us to drive the camera system directly from open source code running on ARM processors.

libcamera presents a C++ API to applications and works at the level of configuring the camera and then allowing an application to request image frames. These image buffers reside in system memory and can be passed directly to still image encoders (such as JPEG) or to video encoders (such as h.264), though such ancillary functions as encoding images or displaying them are strictly beyond the purview of libcamera itself._

I trying to use this camera different ways.

FIrst, I can use with emulator legacy stack running command:

libcamerify baresip

/usr/local/bin/libcamerify: Load an application with libcamera V4L2 compatibility layer preload
/usr/local/bin/libcamerify [OPTIONS...] executable [args]
 -d, --debug    Increase log level

With thit config i get 18-25 fps at 640x480. Rasp cpu is not loaded. I need more resolution and 30 fps.

Looking old issuues and forum i see that baresip can get video from gstreamer or using v4l2_codec (#283)
But in current baresip verison i can see this modules.
Is this modules was deleted?
I cant understand why at this resolution 25 fps dont stable and no 30 fps.
Also at bigger resolution i need also 30 fps.

I am trying making like this (chatgpt help) libcamera-vid with h264 to stdin/stdout or v4l2loopback like

sudo modprobe v4l2loopback devices=1 video_nr=25 card_label="VirtualCam" exclusive_caps=1

libcamera-vid --width 640 --height 480 --framerate 30 --codec yuv420 --output /dev/video25

also with ffmpeg (chatgpt help)
libcamera-vid → named pipe → baresip with FFmpeg

and gst

gst-launch-1.0 libcamerasrc ! video/x-raw,width=640,height=480,framerate=30/1 \
  ! v4l2h264enc extra-controls="controls,video_bitrate=1000000" \
  ! h264parse config-interval=1 \
  ! v4l2sink device=/dev/video25

Any ideas?
Thank you)

I will look. Thanks.
How you think - can baresip make videocalls with 1024x768, 720, 1080 at 30 fps with raspberry compute module 4?
I need only capture video with SIP.
It has


- Broadcom BCM2711 quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
- H.265 (HEVC) (up to 4Kp60 decode), H.264 (up to 1080p60 decode, 1080p30 encode) 
- OpenGL ES 3.1, Vulkan 1.0
- Options for 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM (depending on variant)

https://www.raspberrypi.com/products/compute-module-4/?variant=raspberry-pi-cm4001000

Or you know other small boards that can do this?

Sorry, i will continue question about v4l2_codec .
As i understand i can use this for the camera with h264 encoding,
I have usb camera with such options.
