  • 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 :

    VBR="1000k"
    
FPS="30"
    
QUAL="ultrafast"
    
YOUTUBE_URL="rtmp://b.rtmp.youtube.com/live2"

    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 ?
