How to stream to the stream name come in response from Youtube livestream api
7 décembre 2018, par Anirudha GuptaI am calling this API https://developers.google.com/youtube/v3/live/docs/liveStreams/insert ? to get stream name from Livestream API

}I see a response like this, When I use OBS to stream to this RMTP URL it doesn’t have the title I set in the stream as you can see come in response. I am getting stream name but not sure if I do it correctly.
If I call the path as
rtmp://a.rtmp.youtube.com/live2/steamnamefromurl/mykey
it’s work but not have the title I set by call API. Anyone please check the page and help what I am going wrong. What I am looking for is get the title and description set for stream, or verified that I am doing it correctly.
