Has anyone had success actually taking the FPV video feed and piping that to LFLiveKit or Streamaxia (or another live streaming SDK) on iOS?

I'm aware there have been some posts on here that were somewhat inconclusive as well as the objective C example DJI put out which is a bit dense and i'm a newer developer only fluent in Swift.

Anyone have tips/code snippets in swift to successfully stream the video feed to an RTMP destination?

I have no test with LFiveKit or other, but you can try to fetch the original video buff from the videoFeed:didUpdateVideoData method and then implement your own live stream.
