  • 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 ?

  • lavfi/spp : add "quality" option in runtime change path

    lavfi/spp : add "quality" option in runtime change path

    it's stranage to use option "level" in runtime change path but used
    
"quality" in option, add "quality" in runtime change path, it's more
    
intuitive and keep the "level" for compatibility.
