How can I stream multiple audio files and a static JPEG image via the terminal?

  • 1

Hello Minex Tuts team, I’ve been trying to find a solution to do a live stream radio 24/7 on my channel for a few days. I’ve already seen two other articles here on how to do this with a single video file and also with a video and audio file separately, however what I really need to do is a stream of several audios with the concat function and an image of static video. I got this code from somewhere on the internet (I don’t remember where) and tried to make an adaptation with the code you already have here, but I was not successful. can you help me?

Here is the code spoken:

#! / bin / bash

VBR = “1500k”
SPF = “25”
QUAL = “ultrafast”
YOUTUBE_URL = “rtmp: //a.rtmp.youtube.com/live2”
YOUTUBE_KEY = “xxxx-xxxx-xxxx-xxxx-xxxx”
VIDEO_SOURCE = “/ home / ubuntu / Video / live1.mp4”
AUDIO_ENCODER = “aac”

ffmpeg \
-stream_loop -1 \
-re \
-i “$ VIDEO_SOURCE” \
-thread_queue_size 512 \
-stream_loop -1 \
-re \
-f concat -i audiofiles.txt \
-c: v libx264 -preset $ QUAL -r $ FPS -g $ (($ FPS * 2)) -b: v $ VBR -bufsize 3000k -maxrate $ VBR \
-c: a $ AUDIO_ENCODER -ar 44100 -b: a 128k -pix_fmt yuv420p \
-f flv $ YOUTUBE_URL / $ YOUTUBE_KEY

The question I have is: where should I keep this file “audiofiles.txt”, in the root of the user “ubuntu” or in the folder that contains the songs for example “/home/ubuntu/music/audiofiles.txt”?

If you can help I will be very grateful, you have already achieved much bigger things and are very good at it!

A hug from Brazil!

    Hi there,  to successfully streaming a radio on YouTube you have to create a radio server first. I will upload a video probably in next week how to create a 27x7 radio channel on YouTube. You will resolve the problem there. Thank you. MineX Tuts

      Friends, I managed to solve it in a much simpler way than I imagined. I'll leave here the code I used and the comments will follow below shortly after: #! /bin/bash VBR="1500k" FPS="24" QUAL="superfast" YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2" YOUTUBE_KEY="spjs-50hd-ujx2-t2ma-1xe9" VIDEO_SOURCERead more

      Friends, I managed to solve it in a much simpler way than I imagined. I’ll leave here the code I used and the comments will follow below shortly after:

      #! /bin/bash

      VBR=”1500k”
      FPS=”24″
      QUAL=”superfast”

      YOUTUBE_URL=”rtmp://a.rtmp.youtube.com/live2″
      YOUTUBE_KEY=”spjs-50hd-ujx2-t2ma-1xe9″
      VIDEO_SOURCE=”/home/ubuntu/video/BG Fundo 01 720p.mp4″
      AUDIO_ENCODER=”aac”

      ffmpeg \
      -stream_loop -1 \
      -re \
      -i “$VIDEO_SOURCE” \
      -thread_queue_size 512 \
      -stream_loop -1 \
      -re \
      -f concat -i /home/ubuntu/music/audiofiles.txt \
      -map 0:v:0 -map 1:a:0 \
      -map_metadata:g 1:g \
      -c:v libx264 -preset $QUAL -r $FPS -g $(($FPS *2)) -b:v $VBR -bufsize 3000k -maxrate $VBR \
      -c:a $AUDIO_ENCODER -ar 44100 -b:a 128k -pix_fmt yuv420p \
      -f flv $YOUTUBE_URL/$YOUTUBE_KEY

      By doing this I was able to concatenate the audio files without generating another output.mp3 file for streaming. The observations that I took as a rule and that make a total difference in this type of code are as follows:

      I made the mapping of the video input and then audio, since in this case the video input was informed first.

      This mapping only works if the lines “-map 0: v: 0 -map 1: a: 0 ” and “-map_metadata: g 1: g ” are just below the listed concatenated file which is audiofiles.txt and if they are before the call to the Audio and Video Codec that starts from the line “-c: v libx264 -preset (…)” onwards.

      The concatenated files are in the same example directory as the “audiofiles.txt” file and their contents are as follows:

      ffconcat version 1.0
      file spontaneous01.mp3
      file spontaneous02.mp3
      file audiofiles.txt

      Filenames with quotes or double quotes didn’t work at all, I don’t know the specific reason for that, but it really didn’t work.

    • Much obliged! If possible, that this tutorial teaches you how to do something with a radio server via code, just like the first video you posted on YouTube, it was a lot of inspiration for me!
