Connect your video source to Castr

There are 3 options to connect your video source to Castr:

  • Publish: Stream directly from your hardware/software encoder to Castr through RTMP and SRT entry points. To start, paste the RTMP URL and Streaming Key or the SRT URL to your encoder.

Click Recommend settings for the best streaming setup with Castr.

  • Pull: Castr can pull HLS, RTMP, RTSP, MPEG-TS streams from other sources. Paste the URL in Pull mode and your stream will appear in Castr.

  • Webcam: Use your device's webcam (video and audio) to start streaming right away without having to setup an encoder.

Get RTMP Pull of your Multistream

Castr provides RTMP Pull link if you need to use Castr as a live video source. Simply click Get RTMP Pull to have the URL saved to your clipboard.

Please note that Castr does not allow embedding RTMP Pull links in public players.

Chat overlay

You can sync chat messages from one or multiple platforms to Castr while multistreaming.

To use the chat overlay with Facebook Page, YouTube, and Twitch, you must add the platforms using API (login method) and not the custom RTMP method.

1. Connect the platforms you are multistreaming to, and toggle them ON

2. Go to Chat Overlay and click Generate Chat URL

Copy the URL to the browser plugin of your encoding software, or click Open Chat App to open a new chat browser.

(Note: Chat Overlay only works on Facebook Page, YouTube, Twitch streams, and not Facebook Timeline.)
