• Ffmpeg live streaming to Youtube - "Connect streaming software to start preview"

  10 septembre 2019, par Zoltan Fedor

  I have an rtsp feed (H.265) which I am trying to stream to YouTube Live, but whatever I do YouTube Studio just showing the waiting icon with "Connect streaming software to start preview".

  .sh file for streaming :

  Basically all looks good to me - still, in YouTube Studio only the waiting icon with the "Connect streaming software to start preview" message is visible, not video feed.

  Any ideas ?
