[FFmpeg-user] Infinite loop randomized stream to rtmp server

As the subject implies, i have troubles to make a running ffmpeg command
that can do the following:
-Infinite "loop" (must stream undefinetly without breaks between videos)
-Randomized (must reproduce videos in a random order)
After much searching in the web, i came to this:
ffmpeg -y -re -stream_loop -1 -i item1.mp4 -async 1 -vsync 1 -c:a aac
-filter:a loudnorm=I=-23:LRA=1:dual_mono=true:tp=-1 -f flv -ar 44100 -c:v
copy -preset fast -keyint_min 25 "rtmp://live.my.stream"
that correctly streams the video but it breaks on repetition, so it's a no
I tried to remove -stream_loop -1 and implement concat that uses File1.txt
and File2.txt which contain:
and then File2.txt
to simulate an infinite loop and use linux symbolic links to make item1 and
item2 point to different files, with the following command:
ffmpeg -y -re -f concat -i File1.txt -async 1 -vsync 1 -c:a aac -filter:a
loudnorm=I=-23:LRA=1:dual_mono=true:tp=-1 -f flv -ar 44100 -c:v copy
-preset fast -keyint_min 25 "rtmp://live.my.stream"
it correctly streams the first file but it breaks when it tries to open the
second file (link to the file File2.txt) with the following output:
[concat @ 0x55be73c15aa0] DTS 2248 < 8085000 out of order
[flv @ 0x55be73cf4300] Non-monotonous DTS in output stream 0:0; previous:
89833, current: 25; changing to 89833. This may result in incorrect
timestamps in the output file.
Error while filtering: Illegal seek
[flv @ 0x55be73cf4300] Failed to update header with correct duration.
[flv @ 0x55be73cf4300] Failed to update header with correct filesize.
So i'm actually out of options to do infinite stream of random mp4 files, i
really need a hand since i'm new to ffmpeg but i really like it!
