• FFMPEG Stream to Instagram Via instafeed.me OR YellowDuck

  3 mars 2024, par Jintor

  I'm trying to do video stream via RTMP to Instagram with FFMPEG

  


  I'm able to do it to facebook and twitter, but instagram is an other beast...

  


  when I create a live broadcast in rtmp.in or yellowduck I get a stream key

  


  when I do this

  


  ffmpeg -rtbufsize 256M -re -i file.webm -acodec libmp3lame -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 720x1280 -bufsize 6000k -vb 400k -maxrate 1500k -deinterlace -vcodec libx264 -preset veryfast -g 30 -r 30 -f flv rtmps://live-upload.instagram.com:443/rtmp/--key--here--


  


  ffmpeg outputs nothing, no error and I see no video in instafeed panel :(

  


  In other network I got sometimes error in ffmpeg log... but when it's to instagram : just blank nothing

  


  what do I miss ?

  


  here the log

• ffmpeg "steam" cbr gop

  30 mars 2021, par Jintor

  It's about live video streaming to STEAM... with ffmpeg

  


  I have this command

  


  ffmpeg -re -i file-from-webcam.webm -deinterlace 
-c:v libx264 -pix_fmt yuv420p -preset veryfast 
-tune zerolatency -c:a aac -b:a 128k -ac 2 -strict -2 -crf 18 
-r 30 -g 60  -vb 1369k -minrate 1369k -maxrate 1369 -ar 44100 -x264-params "nal-hrd=cbr" 
-vf "scale=1280:720" -profile:v main 
-f flv "rtmp://ingest-rtmp.broadcast.steamcontent.com/app/steam_...."


  


  but after a few seconds, the stream stops and the log of steam says

  


      Make sure your upload key-frame interval is set to 2 seconds 
and use constant bitrate (CBR). 
Limit your encoders group of picture (GOP) to at most two times your framerate.


  


  but I do have -x264-params "nal-hrd=cbr" and -r 30 -g 60 framerate 30 GOP 60...

  


  Is there something wrong in the ffmpeg command ?
Or is it linux server related ?

  


  **** The SAME ffmpeg command work very nicely in youtube, twitter, twitch, dlive, facebook, etc...

  


  so what I'm I missing to get it work for steam ?

  


• ffmpeg streaming simultaneously synchronized delay to multiple social networks

  4 avril 2021, par Jintor

  I'm able to stream simultaneously using ffmpeg to youtube, twitter, facebook, twitch ... simultaneously BUT the issue is the following : each network have their own delay

  


  in 1 network : 15 seconds delay, an other : 10 seconds delay, etc

  


  I tried 2 different ways

  


  • 1 ffmpeg per network => Signal is strong and stable

  


  • 1 ffmpeg with tee muxer to many at once => horrible, unstable, 1 network accepts it and some other says signal poor or too low bitrate...

  


  ----------- for example I use this for each social network ------------------------------

  


  /usr/bin/ffmpeg -re -i input.mp4 -deinterlace -c:v libx264 -pix_fmt yuv420p 
-preset veryfast -tune zerolatency -c:a aac -b:a 128k -ac 2 -crf 18 -r 30 -g 60  
-b:v 2369k -minrate 2369k -maxrate 2369k -ar 44100 -qscale:v 2 -vf "scale=-2:1080" 
-profile:v main -bufsize 2369k -f flv "rtmp://a.rtmp.youtube.com/live2/key"

  • I know that it's a case by case basis and not easy to do, but Is there a way to "fake" a delay with ffmpeg (like youtube->x delay, facebook-> y delay, etc) ?

    


  


  • or is there any synchronizing mechanism or timing option in ffmpeg ?

    


  


  • or any other approach ?
