convert ffmpeg bat file to Linux shell script

[wiseant]

Hi

I have been using this ffmpeg batch file to check for video errors

c:\ffmpeg\bin\ffmpeg -v error -i "%~dpnx1" -f null - >"%~dpnx1.error.txt" 2>&1
pause

I just drag and drop a file or folder onto the .bat file

Can someone convert this to a Linux shell script

TIA

#!/bin/bash
SAVEIFS=$IFS
for file in $*
do
ffmpeg -v error -i $file -f null - > $file.log
done
IFS=$SAVEIFS

Save as whatever.sh to run do sh whatever.sh file.mkv

To have dragband drop you need a whatever.desktop file. It doesn't have to actually be on the desktop. Example one chance to whatever you are the script as. On my phone so will clean up more later.

[Desktop Entry]
Type=Application
Name=ac-3 2 channel

Thank you for taking the time to reply

I was able to figure it out - here is my script

for mediafile in *.mkv *.mp4; do
echo $mediafile
ffmpeg -v error -i "$mediafile" -f null - >"$mediafile.error.txt" 2>&1
echo "finished error-check on $mediafile"
done
echo "all done"
$SHELL

and I did create a desktop file:
[Desktop Entry]
Encoding=UTF-8
Name=Drop Over Me
Comment=Execute the script with the file dropped
Exec=xfce4-terminal -e "/home/unoit/Downloads/auto_ffmpeg.sh"
Icon=utilities-terminal
Type=Application
Terminal=true
StartupNotify=true

I am not entirely sure what entries I should and should not have in my file.desktop

In Linux Mint I can drag a mp4 or mkv video from a directory to my desktop file and it will error-check all of the mp4 and mkv files

However this does not work for me in antiX distro - here I have to have the script in the same folder as my videos and I can double-click the script or run it from the terminal

In your desktop file for the Exec entry you are using %F - what does this do?

[dannyboy48888]

The %F passes all file names to the script when you drop a list on the desktop file. %f would do one process per filename (you don't want that). Without %F the desktop file won't work as it's not passing a name to the script to process. Sorry about the late reply will write you a script/desktop file if needed. Works on xfce in my case

@dannyboy48888

In order to work using antiX distro, my scripts need to be in the same directory as my video files - then I double-click the .sh file and it processed the videos in that directory - or I can run this:

cd /media/Backup/Walking; ./demux_audio.sh in terminal - or drag and drop demux_audio.sh to terminal


I have five scripts that I use - it would be easier if I could just drag and drop the folder or one file if it will also process the other relevant files

here is my demux_audo.sh:

for mediafile in *.mp4; do
echo $mediafile
ffmpeg -i "$mediafile" -vn -acodec copy "${mediafile%.mp4}.m4a"
echo "finished demuxing $mediafile"
done
$Shell

I made a .desktop file for demux_audio.sh
[Desktop Entry]
Type=Application
Name=DemuxAudio
Comment=demux audio from video file[s]
Icon=utilities-terminal
Exec=sh /media/Backup/Walking/demux_audio.sh %F
Terminal=true

when I drag the video folder onto demux_audio.desktop - "Failed to execute child process 'xterm" (No such file or directory"

when I drag a video file onto demux_audio.desktop - "Failed to execute child process 'xterm" (No such file or directory"
