Found this through upwork.
To loop the input forever, try changing line 30 to
ffmpeg -stream_loop -1 \
From the manpage:
-stream_loop number (input) Set number of times input stream shall be looped. Loop 0 means no loop, loop -1 means infinite loop.

Changing the script so it supports looping mp3s with a still image or video would be pretty simple too if you need help.

@xcko can you help me do looping ogg files with a gif/video
