This workflow explains how send live-video from a RTMP encoder to a channel, and add real-time closed captioning created by an external operator.

Step 1:

Create a new channel or use one created before. Create a RTMP encoder video source and enable it.

Step 2:

Click on the CC tab under the preview player, select the 3rd option, copy the credentials, and pass them to your captions operator.

Important: remember that an RTMP live stream must reach Videolinq before you send closed captioning.

Step 3:

Click on the "Encoder" tab and copy the RTMP path and stream key.

Step 4:

For this demonstration we used the OBS Studio software. Read this article how to configure OBS. Copy the RTMP path and stream key to the proper window.

Step 5:

Push on "Go Live". This will send video to the player (if you use one).

Step 6:

Start destination(s) and confirm video plus closed captioning is visible.

Step 7:

To stop the stream go in reverse order - stop the destination(s), stop the channel (stop "Live"), stop the RTMP encoder, and stop the video source.
