File browser: Get total duration of selected audio/video files

Question

I would like to know how I can know the total duration of selected audio/video files in one of the Linux file managers, if it's possible.

I use Ubuntu 18.04 LTS, and its default file manager is Files AKA Nautilus.

Answer 1

Here is a Nautilus Script
- Select files in nautilus
- Right-click on it
- In context menu, select Script > NameOfScript

Installation:
Install the mediainfo program if not present sudo apt install mediainfo
Save the script to a file in ~/.local/share/nautilus/scripts
Make it executable chmod +x ~/.local/share/nautilus/scripts/scriptname
Visit the scripts directory once with nautilus nautilus ~/.local/share/nautilus/scripts

#!/bin/bash

# Selected fileslist to Array
OLDIFS=$IFS
IFS=$'\n'
fileArray=($NAUTILUS_SCRIPT_SELECTED_FILE_PATHS)
IFS=$OLDIFS

# Length of array: total num of selected files
NbFiles=${#fileArray[@]}

# The loop 
for (( i=0; i < ${NbFiles}; i++ ));
do
    # Get duration if file is media (audio or video)
    buff=$(file -N -i "${fileArray[$i]}" | grep -E 'audio|video')
    if [ ! -z  "$buff" ]
        then
            # mediainfo gives duration in milliseconds, easy to sum up
            MediaDuration=$(mediainfo --Output='General;%Duration%' "${fileArray[$i]}")
            TotalDuration=$((TotalDuration + MediaDuration))
            NbMedia=$((NbMedia + 1))
    fi
done

# Format Duration: milliseconds to H:M:S
Seconds=$((TotalDuration / 1000))
FormattedDuration=$(printf '%02dh:%02dm:%02ds\n' $(($Seconds/3600)) $(($Seconds%3600/60)) $(($Seconds%60)))

# Build report
ReportText="${NbFiles} File"
test $NbFiles -gt 1 && ReportText="${ReportText}s"
ReportText="${ReportText} selected\n"
test $NbMedia -gt 0 && ReportText="${ReportText}${NbMedia} media file" || ReportText="${ReportText}No media file"
test $NbMedia -gt 1 && ReportText="${ReportText}s"
test $NbMedia -gt 0 && ReportText="${ReportText}\nTotal duration: ${FormattedDuration}"

zenity  --info --no-wrap --text="${ReportText}"

Nice script, Im new with coding and ijust replaced some of the code Thank you a lot

#!/bin/bash

# Selected fileslist to Array
IFS=$'\n'
fileArray=($(find $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS -type f | grep -iE "\.webm$|\.flv$|\.vob$|\.ogg$|\.ogv$|\.drc$|\.gifv$|\.mng$|\.avi$|\.mov$|\.qt$|\.wmv$|\.yuv$|\.rm$|\.rmvb$|/.asf$|\.amv$|\.mp4$|\.m4v$|\.mp4$|\.m?v$|\.svi$|\.3gp$|\.flv$|\.f4v$"))
