proto4webrtc-codegen

Generates typed mediasoup producer code (pymediasoup) from protobuf messages annotated with proto4webrtc options. The generated code runs on the proto4webrtc pip package (the runtime), which this distribution deliberately does not depend on — generate at build time, ship only the runtime:

pip install proto4webrtc[compiler]   # runtime + this generator
python -m proto4webrtc_codegen --proto path/to/protos --out out/

Writes proto4webrtc_gen/producers.py under --out (plus an __init__.py re-export). proto4webrtc/options.proto is bundled, so your proto root only needs to import it.

Also installs the raw protoc plugin protoc-gen-proto4webrtc_python (--proto4webrtc_python_out).

ROS2 interfaces

proto4webrtc_codegen.ros2 renders ROS2 .msg/.srv from the same protos, so an ament interface package can be generated at colcon build time instead of hand-maintained. Optional and dependency-free — nothing imports it unless you do — and the proto4webrtc annotations are not required, so it also works on plain protos:

python -m proto4webrtc_codegen.ros2 --proto path/to/protos --out src/my_interfaces

Writes msg/<Message>.msg and srv/<RpcMethod>.srv under --out, removing generated files that are no longer produced and leaving hand-written ones alone.

Pass --ros-package my_interfaces to python -m proto4webrtc_codegen or python -m proto4webrtc_codegen.cpp to generate the conversions too: message.to_ros() returns the ROS2 message, and build_<message>_proto_from_ros(ros_message) returns the proto one.
