Hello.

We used example from [https://www.wowza.com/docs/how-to-use-generic-stream-target-api-to-prepare-apple-hls-streams-for-ad-insertion-scte-35](https://www.wowza.com/docs/how-to-use-generic-stream-target-api-to-prepare-apple-hls-streams-for-ad-insertion-scte-35) and adjusted it for our needs with Ads insertion, but we noticed, that there is no keyframe at the beginning of the media segment after splice. It is crucial problem because if we change content between scte-35 signals we got decoding errors since first frame references on the keyframe that does not exist anymore.

How we can tell transcoder in Wowza to start new GOP after SCTE-35 event?

Thanks.
