  • No sound when running ffmpeg on youtube live

    28 mai 2020, par Bartonsen

    Despite my limited knowledge in ffmpeg, I've managed to livestream my birdbox camera to youtube using ffmpeg running on a raspberry pi. The camera has also audio and by using local vlc in windows with rtsp, the audio is ok.

    



    However, on youtube there is no sound (same rtsp command as used locally in windows), and I see this "warning" in youtube studio : "The current bitrate (0) of the audio stream is lower than the recommended bitrate. We recommend using a 128 Kbps bitrate for the audio stream."

    



    How can I get the sound through youtube ?
This is the command I run. The command was found on the net, and I adopted it for my usage, and got video working straight away :
