What is Castlify?

Castlify helps you distribute an existing video stream to one or multiple live destinations without running extra streaming infrastructure.

When to use Castlify

Use Castlify if you already have a video stream or compatible video input, and you want to send it to:

  • RTMP destinations (YouTube Live, Facebook Live, Twitch, and many others)

  • SRT destinations (for contribution-style endpoints or professional workflows)

What you need to get started

Have these ready:

  • A supported input source, such as:

    • An HLS input URL (a link ending in .m3u8)

    • A DASH input URL (a link ending in .mpd)

    • An MP4 or other compatible video file source, depending on your workflow. You can see here more info about the video formats supported.

  • At least one destination:

    • RTMP: RTMP URL (server) + Stream Key (or a full RTMP URL depending on the platform)

    • SRT: Host + Port (and any required parameters such as StreamID or passphrase)

How Castlify works (in one line)

Video stream input → Castlify → RTMP/SRT output(s)

You can start with one destination and add more later.

What Castlify is not

Castlify is focused on distribution. It does not replace a full live production stack.

  • It’s not a video editor or live switcher.

  • It doesn’t require OBS/vMix/Wirecast if you already have a video stream link.

Next step

Go to Create your first stream to send your video stream to your first RTMP or SRT destination.
