• Icecast to Youtube Live w/ Track Meta data

  22 novembre 2018, par eusid

  I am using ffmpeg to stream a still image along with my Icecast stream to youtube. I would like to give the artists credit by displaying their names on the image or perhaps even using a visualizer type thing.

  I am curious how people have solved this issue to get the meta data on the image, or even use a visualizer in the past. I want to do this headlessly from my server so I don’t have to run OBS or something on my desktop. I would hope to not have to reinvent the wheel, but if you could point me in the right direction I’ll build the wheel if asking for a completed wheel gets me down votes.

  How is this typically solved ? Mainly getting the text on the image and the stream updating with the new image. I could write something with pillow to do this perhaps. Not sure if it would work.

• How to stream 24/7 on youtube (audio + video) with FFMPEG

  29 septembre 2023, par Carter510

  I plan to create a 24/7 stream with a video and a musical background which is located in a /Playlist folder.
I would like the music playlist to be played randomly and if a piece of music is corrupted or cannot be played, the program moves on to the next one.

  


  The problem is that with my command every time the music changes the stream stops.
Any suggestions ?

  


  #!/bin/bash

VBR="4500k"
FPS="30"
QUAL="superfast"

YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"
KEY="XXXX-XXXX-XXXX-XXXX"

VIDEO_SOURCE="fireplace.mkv"
AUDIO_FOLDER="/home/administrateur/Documents/Youtube/Playlist"

while true; do
    # Joue la vidéo en boucle
    ffmpeg -re -stream_loop -1 -i "$VIDEO_SOURCE" \
    -thread_queue_size 512 -i "$(find "$AUDIO_FOLDER" -type f -name "*.mp3" | shuf -n 1)" \
    -map 0:v:0 -map 1:a:0 \
    -map_metadata:g 1:g \
    -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
    -acodec libmp3lame -ar 44100 -threads 6 -qscale:v 3 -b:a 320000 -bufsize 512k \
    -f flv "$YOUTUBE_URL/$KEY"
done


  


  I would like the fireplace.mkv video to play without interruption, for the music to be chosen randomly without ever stopping. And if one of the songs cannot be played, it is skipped.

  


• Stream to youtube from xvfb using ffmpeg and x11grab

  13 décembre 2017, par Ivan Sergeev

  I want to make stream from virtual display to youtube via ffmpeg.
  I’m using this code :

  #! /bin/bash
  
  
  
  BITRATE="2500k"                                    
  
  FPS="30"                                       
  
  
  
  YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"  
  
  YOUTUBE_KEY="..."                                     
  
  
  
  SOURCE="./test.mp4"
  
  
  
  export DISPLAY=44
  
  sudo xvfb-run -a -n 44 -l -s "-screen 0, 1280x720x24" google-chrome -start-maximized https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif --no-sandbox >/dev/null &
  
  
  
  ffmpeg -threads 0 -y -v verbose -re \
  
   -f x11grab -video_size 1280x720 -i :44 \
  
   -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -r $FPS -g $(($FPS * 2)) -b:v $BITRATE -bufsize 512k \
  
   -acodec libmp3lame -ar 44100 -threads 0 -crf 25 -b:a 712000 -bufsize 512k \
  
   -f flv "$YOUTUBE_URL/$YOUTUBE_KEY"

  And I don’t receive any errors, but youtube cannot start stream(

  In my log :

  Stream mapping:

  frame=   20 fps=4.9 q=15.0 size=     294kB time=00:00:03.96 bitrate= 608.3kbits/s

  etc.

  However, if I do stream from file, but not x11grab stream is starting normal.

  What I’m doing wrong ?
  Any ideas, guys, please)
