  • Streaming to YouTube using FFmpeg Problems

    12 septembre 2022, par jason

    I am trying to stream to a live event I have created inside of YouTube. I am trying to stream a already created video. The command I am using is noted below.

    



    The problem I have is that YouTube is showing the Streaming status as good (picture attached) and it seems to be receiving the data. But there is no sound and no picture in the live event. I'm not sure what the issue could be.

    



    ffmpeg -re -y -i input.mp4 -vcodec libx264 -b:v 600k -r 25 -s 640x360 -filter:v yadif -ab 64k -ac 1 -ar 44100 -f flv "rtmp://a.rtmp.youtube.com/live2/KEY"
