  • FFMPEG stream video to Youtube Live

    13 juin 2022, par BlessedHIT

    I have a mov file and I'm using ffmpeg to stream it to youtube live using the following command,

    


    ffmpeg -re -i "episode.mov" -pix_fmt yuvj420p -x264-params keyint=48:min-keyint=48:scenecut=-1 -b:v 4500k -b:a 128k -ar 44100 -acodec aac -vcodec libx264 -preset medium -crf 28 -threads 4 -f flv "rtmp://a.rtmp.youtube.com/live2/YOUTUBE.LIVESTREAM.KEY"


    


    But im getting the following message on youtube,

    


    YouTube is not receiving enough video to maintain smooth streaming. As such, viewers will experience buffering


    


    My ffmpeg output showed my bitrate being between 800 - 1000 mbps, way lower than what i have specified in my ffmpeg command.

    


    I am using a not so powerful virtual machine, and so i thought this might be why i am not getting the desired bitrate.

    


    To overcome my hardware limitations, I then decided to encode the file for streaming using this command :

    


    ffmpeg -i episode.mov -c:v libx264 -preset medium -b:v 4500k -maxrate 4500k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 episode.flv


    


    Then I stream copy the file using :

    


    ffmpeg -re -i episode.flv -c copy -f flv "rtmp://a.rtmp.youtube.com/live2/YOUTUBE.LIVESTREAM.KEY"


    


    And that seems to give me a stream that youtube is happy with.

    


    My question is, is there a way I can rewrite my ffmpeg command to livestream with the desired bitrate without needing to first encode my mov to another file or is adding more memory the only way forward here ?
