How to Caption OBS Streaming Video with Falcon from EEG Video


As one of the most popular streaming encoders, the free and open source OBS Studio is being used by more content producers than ever. OBS-based producers are broadcasting to fast-expanding audiences, making closed captioning increasingly important. Captioning can be used to create highly engaging readable video, as well as to satisfy ADA accessibility guidelines for the hearing impaired.

OBS can stream easily to YouTube, Twitch, Facebook Live, and more. EEG Video’s Falcon Live Streaming RTMP Encoder makes it equally easy to add closed captioning for OBS. Read this quick tutorial to learn how.

OBS, Falcon, and the Streaming Platform: Starting the Conversation

OBS links Falcon and the streaming platform destination through the use of an RTMP Ingest URL and Stream Key. In this workflow, OBS sends the video source to Falcon where the video gets captions embedded. Next, the video with the embedded captions are returned to Falcon and sent to the stream’s destination.

To get started, connect your video source to OBS, then visit EEG Cloud to access Falcon.

After creating your Falcon instance, you are supplied with an RTMP Ingest URL and Stream Key. Next, copy and paste them into the Streaming Media Encoder—in this case, OBS.

Take these steps in OBS to complete that process:

  1. Navigate to Settings.
  2. Click Stream.
  3. Paste the copied RTMP Ingest URL into the Server field.
  4. Paste the copied Stream Key into the Stream Key field.
  5. Click Apply and then OK to complete this process.

Once that process has been completed, click Start Streaming. This will now send your video source to Falcon to be captioned by your choice of EEG’s Lexi Automatic Captioning service or by human captioners. The caption data is embedded by Falcon, then returns to the stream displaying captions.

The video and captions will then be displayed in the Input and Output windows in Falcon, and should appear on your destination.

NOTE: You must click the “CC” icon in Falcon in the Output window to see captions in Falcon.

Captions can be viewed on most web players, mobile device and VOD recordings that support 608/708 embedded closed captions.
