Is it possible and is there example code about injecting cue points / metadata using the GoCoder SDK? All I can find is old articles ([https://www.wowza.com/docs/how-to-inject-cue-points-or-metadata](https://www.wowza.com/docs/how-to-inject-cue-points-or-metadata)) that describe adding cue points later, but I want to be able to add the cue points through the SDK while recording. ---

Metadata API is a prioritized feature for GoCoder SDK. This is work in progress. We are planning to deliver this feature in the coming weeks or months. ---

Hi, This is currently not supported for the GoCoder SDK, although it is in our product roadmap. Do keep an eye on our [release notes for GoCoder SDK](https://www.wowza.com/resources/gocodersdk/docs/1.0/) and see when this feature is added. Michelle ---

I’ve been using metadata insertion in GoCoder SDK for a long time now. Became available for testing sometime in the beginning of this year, not sure when it became official. ---

Interesting! Mind sharing some code how you do this? ---

As I’m not an IOS/android developer, here’s some code sample from my colleague doing the actual development - I’ll put it in a separate post, as reply here has limited number of characters. ---

Metadata is now an included feature in the SDK. Please refer to the sample app included in the SDK zip file for examples on how to use this. Michelle
