• ffmepg enque and deque files list that streams to youtube

  17 janvier 2019, par andNn

  I have bunch of files ... commonly knows as myPlayList.txt
  example : vi myPlayList.txt

  a.mp4
  
  b.mp4
  
  c.mp4

  now when i run ffmpeg it starts streaming a.mp4, then b.mp4

  while b.mp4 is still streaming if i add d.mp4 to the fileList or via any other command .. it should get enqued. also if i now want to remove a file from the list .. i should be able update the file list from command or updating the file. But while i am changing the filelist the current stream should not change/break.

  My current script for single file is :

  VBR="2500k"                                    # Bitrate de la vidéo en sortie
  
  FPS="30"                                       # FPS de la vidéo en sortie
  
  QUAL="medium"                                  # Preset de qualité FFMPEG
  
  YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"  # URL de base RTMP youtube
  
  
  
  SOURCE="/a/b/land.mp4" # single file path
  
  
  
  KEY="..."                                     # Clé à récupérer sur l'event youtube
  
  
  
  ffmpeg \
  
     -i "$SOURCE" -deinterlace \
  
     -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
  
     -acodec libmp3lame -ar 44100 -threads 6 -qscale 3 -b:a 712000 -bufsize 512k \

• Produce high quality GIF with Fluent FFmpeg

  3 mars 2023, par Mensur

  I'm trying to generate high quality GIF's with Fluent FFmpeg, which is a wrapper for FFmpeg for Nodejs and i'm stuck.
What i need to do is add to add palletegen & palleteuse and i found a great example how this can be use directly in FFmpeg here.

  


  However, I need help to add this in fluent ffmpeg code below. Does anyone have any example how I can produce high quality GIF's with fluent ffmpeg below ? The code below is generating GIF's but not that high quality.

  


      const inputPath = videoname + ".mp4";
    const outputPath = videoname + ".gif";
    const startTime = "00:00:05";
    const duration = "00:00:08";
    const fps = 10;

    ffmpeg(videotemp)
    .setStartTime(startTime)
    .setDuration(duration)
    .fps(fps)
    .size("500x300")
    .output(outputPath)
    .on("end", () => {
        console.log("Video has been converted to " +outputPath+ " animation successfully!");
    })
    .on("error", (err) => {
        console.log("Error: " + err.message);
    })
    .run();
