 I've tried to loop a short mp4 file with the {{{-stream_loop}}} parameter
 and get a {{{ Error while filtering: Operation not permitted}}}
 {{{
 ffmpeg -report -hide_banner -y
 -stream_loop -1 -i /home/nas/loop.mp4
 -c:v libx264 -b:v 5M -s 1280x720 -r 50 -pix_fmt yuv420p -c:a libfdk_aac
 -b:a 192k -ac 2 -ar 44100
 -f flv -fflags +genpts+igndts rtmp://[host]/rtmp/monitor_loop
 }}}
 You can find the loop.mp4 and the report log in the attachments.
 It plays once and fails, if it wants to loop.
 And I get the error:
 {{{
 Stream mapping:
   Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264))
   Stream #0:1 -> #0:1 (aac (native) -> aac (libfdk_aac))
