Automator/AppleScript Help

[worldomination]

I have a lot of files to process... over five hundred.

It would be helpful to speed things up a bit.

I'm extracting each movie's audio file in terminal using ffmpeg.

Is it possible to create an application to help with this?

1. open Terminal
2. type ffmpeg -i
3. ask for the movie file
4. type -vn
5. automatically output an audio file with the movie's name in the same directory

Is this possible?

Something like this:

set theInputFile to POSIX path of (choose file of type {"mp4", "mov", "mkv", "m4v"} with prompt "Choose a video file")
set theFileName to name of (info for theInputFile)
--set theOutputFolder to POSIX path of (choose folder with prompt "Please select an output folder:")
set theOutputFolder to POSIX path of theInputFile
set theCom to "/usr/local/bin/ffmpeg -i " & theInputFile & " -vn " & theOutputFolder & "_audio" & ".m4a"
tell application "Terminal"
    do script theCom
    activate
end tell

I left an option to select a different output folder.

Thank you for your your reply!

I modified your script through a little trial and error...

set theInputFile to POSIX path of (choose file of type {"mp4", "mov", "mkv", "m4v"} with prompt "Choose a video file")
set theOutputFolder to POSIX path of theInputFile
set theCom to "ffmpeg -i " & theInputFile & " -vn " & theOutputFolder & "_audio" & ".eac3"
tell application "Terminal"
    do script theCom
    activate
end tell

This might just work.

However, Terminal is inputing and outputing the path as...

/Volumes/Elite Pro Duo/movie.mp4

When it ought to be...

/Volumes/Elite\ Pro\ Duo/movie.mp4

...and I receive an error... unknown file attribute: 2.

Is there a way to change this?

This shoud work for files/folders with spaces in the name

set theInputFile to POSIX path of (choose file of type {"mp4", "mov", "mkv", "m4v"} with prompt "Choose a video file")
set theOutputFolder to POSIX path of theInputFile
set theCom to "ffmpeg -i " & quoted form of theInputFile & " -vn " & quoted form of theOutputFolder & "_audio" & ".eac3"
tell application "Terminal"
    do script theCom
    activate
end tell

It can be done as an Automator service with run Shell Script

for f in "$@"
do
/usr/local/bin/ffmpeg -i "$f" -vn "${f%.*}.eac3"
done

Thank you, bogdanw!

There's no way I could have figured out that on my own.

I don't understand what to do with the second part... Automator service with run Shell Script...

I was able to save the script as an application, though, and that works great. A HUGE time saver.

Cheers!

Glad to help and learn, I didn't know about the -vn option.
An improved AppleScript

set theInputFile to (choose file of type "public.movie" with prompt "Choose a video file")
set theFileName to name of (info for theInputFile)
tell application "Finder" to set theOutputFolder to POSIX path of ((container of theInputFile) as text)
set theCom to "ffmpeg -i " & quoted form of (POSIX path of theInputFile) & " -vn " & quoted form of (theOutputFolder & theFileName) & ".eac3"
tell application "Terminal"
    do script theCom
    activate
end tell

Sorry about the second part, I should have said QuickAction https://support.apple.com/guide/automator/aut73234890a/mac
and it looks like this

It doesn't start Terminal, but does the job in the background. It's probably more useful for small files, rather than large ones where you probably want to see the progress in Terminal.
