pxy is a Go server that routes incoming livestream data from websockets to an external RTMP endpoint.

This project is a work in progress, I'll update more once I'm done with my sleep.

For a side-project of mine, I've to broadcast livestreams through an external service that uses the RTMP protocol. Flutter, and all the web browsers out there do not support said protocol. Therefore, I built pxy to proxy the livestreams from such clients (via websockets) to the broadcasting RTMP servers. Since RTMP is still widely used in the video streaming industry, I thought amateurs like me could benefit from an implementation like pxy for our side-projects and such.

Fundamentally, pxy works well so far. However, there are probably still bugs that needs be ironed out. If you do find any, feel free to open an issue or make a pull request. Meanwhile, pxy could be used as a reference for how a websocket-RTMP proxy could be built. Using it in production now is a really bad idea.

1. Firstly, install FFmpeg on your machine (just Google it).

2. Proceed to clone the project with the command below

git clone https://github.com/chuabingquan/pxy.git && cd pxy-master/

3. Update your RTMP endpoint address under the constants in cmd/pxy/main.go.

const (
	readBufferSize  = 1024
	writeBufferSize = 1024
	publishURL      = "rtmp://global-live.mux.com:5222/app" // This one here.
)

4. Execute the following command to build and run the pxy server

go run cmd/pxy/main.go

5. Access http://localhost:8080 in your browser and supply your stream name/stream key. pxy will append it behind the specified RTMP endpoint address that's mentioned Step 3 (e.g. rtmp://global-live.mux.com:5222/app/{YOUR_STREAM_NAME/KEY})
