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

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

  2. Install build dependencies:

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

  3. 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

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

  2. Install build dependencies:

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

  3. Make sure that the development package of your libcamera is installed, otherwise install the default one:

    sudo apt install -y \
libcamera-dev

  4. 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

  1. You can be on any machine you like

  2. Install Docker and make

  3. Build for every supported architecture:

    make -f utils.mk build

    This will produce the build/mtxrpicam_32 and build/mtxrpicam_64 folders.

Install

  1. Download MediaMTX source code and open a terminal in it

  2. Run go generate ./...

  3. Copy build/mtxrpicam_32 and/or build/mtxrpicam_64 inside internal/staticsources/rpicamera/, overriding existing folders

  4. Compile MediaMTX

    go build .
