  • Youtube stream of looping JPG stops randomly

    6 juillet 2021, par timw99

    Hi I'm fairly new at ffmpeg.

    


    I'm currently trying to get a low FPS Youtube stream working over RTMP using a JPG on loop which content gets changed using a NodeJS script periodically. I'm using the following command to stream (variable 3 is my stream key) :

    


    ffmpeg -re -loop 1 -pix_fmt bgr24 -framerate 5 -i img/now.jpg -re -stream_loop -1 -i output.mp3 -f flv -vcodec libx264 -profile:v main -g 60 -keyint_min 30 -b:v 400k -minrate 400k -maxrate 400k -preset ultrafast -tune zerolatency -bufsize 2000k rtmp://a.rtmp.youtube.com/live2/$3


    


    There's multiple things wrong here. The bitrate doesn't actually stay at 400k/s. It just goes to around 200-1000k and then just starts decreasing until the stream stops (usually at around 200-300k bitrate). It still seems like data is being sent (bitrate and current FPS are still updated (though they're very low) and speed goes parabolic. The frame counter itself just stops and Youtube doesn't continue streaming. See example :

    


    frame=  515 fps=5.0 q=12.0 size=    5803kB time=00:01:42.84 bitrate= 462.3kbits/

    I'm using a Digital Ocean VPS to run it, but the same happens on my own desktop which definitely has the hardware for a simple stream like this. Could it have something to do with me replacing the JPG content while trying to stream it ? I get this error every once in a while, but it seems like it fixes itself judging by the info :

    


    [mjpeg @ 0x562824d1fb40] overread 8
[mjpeg @ 0x562824d1fb40] EOI missing, emulating


    


    I can provide more information if it's needed. Thanks in advance.
