You can use the HTTP **get** method and URL querystring parameters to record live streams. See this section of the Live Stream Record API article: [Recording live streams using URL queries](https://www.wowza.com/docs/how-to-record-live-streams-httplivestreamrecord#livestreamrecordhttpprovider) Salvadore ---

The only real advice I can give in regards to the LiveStreamRecord question is to upgrade Wowza to 3.5 at least. Even better would be to upgrade to Wowza 4.0. To require user authentication for RTSP streams you need to change /conf/[app-name]/Application.xml /RTP /Authentication /PlayMethod to “digest” Salvadore ---

Sir i am operating upon WMS 2.2.4 and am using LiveStreamRecord\_2.0.zip. HTTP method works just fine, but using the API would be a great help. I have made the changes as suggested in the document but the issue still persists. Guide me on the changes i needed make it work. All other features on the server work. And one more thing WMS authenticates all in coming streams through FMLE and goCoder but when ever i am streaming from a android app like OS Broadcaster, no authentication event occurs. How do i get it to authenticate from all streaming apps mobile or non mobile ?
