Hello everyone, I am new here so forgive me if this is in the wrong place. I am new to shell script and am trying to write a script to use with a program called ffmpeg. Would this be something I could get help with here?
This allows you to paste the name of an mp4 file in the window and it will automatically make a folder and print out a frame by frame of the video in it. This was given to me and I added the little mp4 extension to it but that is as far as I can go. Would anyone here be able or willing to show me how to edit this further to do a few other things?
Thank you all for your time and help.

marc::file
MARC::File(3pm) User Contributed Perl Documentation MARC::File(3pm)NAME
MARC::File - Base class for files of MARC records
SYNOPSIS
use MARC::File::USMARC;
# If you have werid control fields...
use MARC::Field;
MARC::Field->allow_controlfield_tags('FMT', 'LDX');
my $file = MARC::File::USMARC->in( $filename );
while ( my $marc = $file->next() ) {
# Do something
}
$file->close();
undef $file;
EXPORT
None.
METHODS
in()
Opens a file for import. Ordinarily you will use "MARC::File::USMARC" or "MARC::File::MicroLIF" to do this.
my $file = MARC::File::USMARC->in( 'file.marc' );
Returns a "MARC::File" object, or "undef" on failure. If you encountered an error the error message will be stored in $MARC::File::ERROR.
Optionally you can also pass in a filehandle, and "MARC::File". will "do the right thing".
my $handle = IO::File->new( 'gunzip -c file.marc.gz |' );
my $file = MARC::File::USMARC->in( $handle );
next( [&filter_func] )
Reads the next record from the file handle passed in.
The $filter_func is a reference to a filtering function. Currently, only USMARC records support this. See MARC::File::USMARC's "decode()"
function for details.
Returns a MARC::Record reference, or "undef" on error.
skip()
Skips over the next record in the file. Same as "next()", without the overhead of parsing a record you're going to throw away anyway.
Returns 1 or undef.
warnings()
Simlilar to the methods in MARC::Record and MARC::Batch, "warnings()" will return any warnings that have accumulated while processing this
file; and as a side-effect will clear the warnings buffer.
close()
Closes the file, both from the object's point of view, and the actual file.
write()
Writes a record to the output file. This method must be overridden in your subclass.
decode()
Decodes a record into a USMARC format. This method must be overridden in your subclass.
