I am trying to figure out which distro this script (scene_splitter.sh) was built for. Everytime I try to use it I get the following error.

x@x-pc:/media/x/WD_2TB_HDD/test$ ./scene_splitter.sh 001.mp4

It seems it was built for using with a distro that allows a folder and a file to have the same exact name, only difference being one a folder and one a file... assuming that distro knows the difference and thus allows it.

Does anyone know how to edit this script so that it doesn't want to create a directory with the exact same name as the file being inputted?

Here is the code for scene_splitter.sh

#/bin/bash



start=0; 

count=0; 

in="$1"

bn="$(basename "$in")"

echo "=============================================================================="

echo "FILE START: $bn"

mkdir "./$bn"



echo "Finding Scene... this might take a while..."

ffmpeg -nostdin -i "$in" -filter:v "select='gt(scene,0.1)',showinfo" -f null - 2>"./$bn/ffout.tmp.txt"



echo "Filtering timestamp... this might take a while..."

grep showinfo "./$bn/ffout.tmp.txt" | grep pts_time:[0-9.]* -o | grep '[0-9]*.[0-9]*' -o > "./$bn/timestamps.tmp.txt"



scenes=$(wc -l < "./$bn/timestamps.tmp.txt")

echo "Found $scenes scenes"

sleep 1



while IFS= read -r line; do

    echo "---------------------------------------------------------------------------"

    echo "SCENE START: $count/$scenes ($start,$line)"

    ffmpeg -i "$in" -ss "$start" -to "$line" -nostdin -y -vcodec libx264 -acodec aac -g 120 -s 1280x720 -r 30 "./$bn/$bn.($count of $scenes).mp4"

    echo "SCENE DONE:$count/$scenes ($start,$line)"

    echo "---------------------------------------------------------------------------"

    start=$line

    count=$(($count+1))

    sleep 1



done <"./$bn/timestamps.tmp.txt"

echo "---------------------------------------------------------------------------"

echo "LAST SCENE START:$count/$scenes ($start,end)"

ffmpeg -i "$in" -ss "$start" -nostdin -y -vcodec libx264 -acodec aac -g 120 -s 1280x720 -r 30 "./$bn/$bn.($count of $scenes).mp4"

echo "LAST SCENE DONE:$count/$scenes ($start,end)"

echo "---------------------------------------------------------------------------"



echo "FILE DONE: $bn"
