Wowza does not support adding cuepoints to a file. It has to be done during recording of a live stream.

Please take a look at these guides for setting this up:

[How to inject cue points or metadata](https://www.wowza.com/docs/how-to-inject-cue-points-or-metadata)

[How to configure closed captioning for live streaming](https://www.wowza.com/docs/how-to-configure-closed-captioning-for-live-streaming)

There are 3rd party tools, e.g. [Captionate](http://www.buraks.com/captionate/), that will add cuepoints to files.

Hi,

The way to get CEA-608 into a live stream (if you don’t have an encoder that does this) is to setup for closed captions using OnTextData by first following [this guide.](https://www.wowza.com/docs/how-to-configure-closed-captioning-for-live-streaming#ontextdata)

Then inject [OnTextData using this method.](https://www.wowza.com/docs/how-to-configure-closed-captioning-for-live-streaming#publishing_ontextdata)

The tool in the above can be adapted to accept text in different ways. The full configuration will convert the OnTextData to CEA-608 in real-time.

The CEA-608 will then make it through the transcoder process.
