ffmpeg opperation not permtted on rtmp

Question

I am trying to make a internet radio using ffmpeg. I have a folder full of mp3 and have a 5sec mp4 that i want to use in a infinite loop. so here is the code i came up with to stream on YouTube

#! /bin/bash

    VBR="1500k"
    FPS="30"
    QUAL="ultrafast"
    YOUTUBE_URL=" rtmp://a.rtmp.youtube.com/live2"
    YOUTUBE_KEY="YOUTUBE_KEY_HERE"
    VIDEO_SOURCE="output.mp4"
    AUDIO_ENCODER="aac"
    
    ffmpeg 
     -stream_loop -1 
     -re 
     -i "$VIDEO_SOURCE" 
     -thread_queue_size 512 
     -stream_loop -1 
     -re 
     -f concat -safe 0 -i audio.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 -flvflags no_duration_filesize $YOUTUBE_URL/$YOUTUBE_KEY

The problem is the i am getting an error saying operation not permitted

here is the error log

I think this error is due to the video that I am looping is too short and the -stream_loop -1 flag seems buggy according to some guys on superuser and stackoverflow.

Is there any other way to fix this

Answer 1

ok i found the solution. you can use the movie filter. it has a loop. You can provide the same file that you want to loop as a input and put a movie filter to it and then chain that to the concat

here is the modified code this may help to understand

#! /bin/bash

    VBR="1500k"
    FPS="30"
    QUAL="ultrafast"
    YOUTUBE_URL=" rtmp://a.rtmp.youtube.com/live2"
    YOUTUBE_KEY="YOUTUBE_KEY_HERE"
    VIDEO_SOURCE="output.mp4"
    AUDIO_ENCODER="aac"

    ffmpeg 
     -stream_loop -1 
     -re 
 -filter_complex movie=/root/LiveStreamRadio/media/output.mp4:loop=0,setpts=N/FRAME_RATE/TB 
     -i "$VIDEO_SOURCE" 
     -thread_queue_size 512 
     -stream_loop -1 
     -re 
     -f concat -safe 0 -i audio.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 -flvflags no_duration_filesize $YOUTUBE_URL/$YOUTUBE_KEY

look at this section

-filter_complex movie=/root/LiveStreamRadio/media/output.mp4:loop=0,setpts=N/FRAME_RATE/TB -i "$VIDEO_SOURCE"
