this part of script

    if [ "$count_dir_video" -gt "1"  ] ;then  53   54                 # make background black hide wallpaper between videos  55                 display=:0 screen -dms "black_background" feh -fxyqz /opt/scripts/black_background.jpg  56                 echo "przed sleep"  57                 #screen -dms "$1" sleep 5  58                 echo "po sleep"  59   60                         while :  61                          62                                 entry in $root_dir_video  63                                  64   65                                 # multiple files  66                                 echo "przed omx"  67                                 screen -d -r "$1" omxplayer -o hdmi -p -b --no-osd --vol 100 "$entry" >> /var/log/sds.log  68                                 echo "po omx"  69                                 done  70                         done  71                 else  72   73                         # single file  74   75                         screen -dms "$1" omxplayer -o hdmi -p -b --loop --no-osd --vol 100 "$root_dir_video"  76                 fi

the problem in line 67 , cannot make work.

i tried other parameter screen combination same.

the idea start every entry in once named screen session.

man screen

   -d -r   attach here , now. in detail means: if session run‐            ning, reattach. if necessary detach  ,  logout  remotely            first.   if   not running create , notify user.            author's favorite.

use lowercase -d -m.
