mediamtx-rpicamera

Raspberry Pi Camera component for MediaMTX.

This is a C-based executable that pulls the Raspberry Camera video feed, encodes it and makes the compressed video available to the server, while listening for incoming commands.

This is embedded into all MediaMTX releases and shouldn't normally be downloaded unless you want to recompile it.

Compile

You must be on a Raspberry Pi, running Raspberry Pi OS Bullseye

Install build dependencies:

sudo apt install -y \
g++ \
xxd \
wget \
git \
cmake \
meson \
pkg-config \
python3-jinja2 \
python3-yaml \
python3-ply

Build:
```
meson setup build && DESTDIR=./prefix ninja -C build install
```
This will produce the build/mtxrpicam_32 or build/mtxrpicam_64 folder (depending on the architecture).

Compile against an external libcamera

You must be on a Raspberry Pi, running Raspberry Pi OS Bullseye

Install build dependencies:

sudo apt install -y \
g++ \
xxd \
wget \
git \
cmake \
meson \
pkg-config \
python3-jinja2 \
python3-yaml \
python3-ply

Make sure that the development package of your libcamera is installed, otherwise install the default one:
```
sudo apt install -y \
libcamera-dev
```
Build with --wrap-mode=default (that disables embedded libraries):
```
meson setup --wrap-mode=default build && DESTDIR=./prefix ninja -C build install
```
This will produce the build/mtxrpicam_32 or build/mtxrpicam_64 folder (depending on the architecture).

Cross-compile

You can be on any machine you like
Install Docker and make
Build for every supported architecture:
```
make -f utils.mk build
```
This will produce the build/mtxrpicam_32 and build/mtxrpicam_64 folders.

Install

Download MediaMTX source code and open a terminal in it
Run go generate ./...
Copy build/mtxrpicam_32 and/or build/mtxrpicam_64 inside internal/staticsources/rpicamera/, overriding existing folders
Compile MediaMTX
```
go build .
```
