• Stream SRT content to Twitch or YouTube Live

Supports SRT streams in caller and listener mode. Runs on MacOS and Ubuntu.

Compliance Table

Here we have a list of supported production software.

Install

cargo install srt_rtmp

# recommended for pretty log viewer (optional)
cargo install bunyan

Generate an SRT test source for example using our testsrc Docker container:

docker run --rm -p 1234:1234/udp eyevinntechnology/testsrc

An SRT stream (in listener mode) is then available at srt://127.0.0.1:1234.

Set your Stream key as ENV STREAM_KEY. Then run the srt-rtmp application:

export STREAM_KEY=$YOUR_STREAM_KEY

srt-rtmp -i 127.0.0.1:1234 -s caller -o live.twitch.tv/app | bunyan

It will connect to the SRT test stream in caller mode as the generated SRT stream is in listener mode. A live stream will be available at rtmp://live.twitch.tv/app/$STREAM_KEY.
