# setcsv(str, sep) - parse CSV (MS specification) input
# str, the string to be parsed. (Most likely $0.)
# sep, the separator between the values.
#
# After a call to setcsv the parsed fields are found in $1 to $NF.
# setcsv returns 1 on sucess and 0 on failure.
#
# By Peter Str\366mberg aka PEZ.
# Based on setcsv by Adrian Davis. Modified to handle a separator
# of choice and embedded newlines. The basic approach is to take the
# burden off of the regular expression matching by replacing ambigious
# characters with characters unlikely to be found in the input. For
# this the characters "\035".
#
# Note 1. Prior to calling setcsv you must set FS to a character which
# can never be found in the input. (Consider SUBSEP.)
# Note 2. If setcsv can't find the closing double quote for the string
# in str it will consume the next line of input by calling
# getline and call itself until it finds the closing double
# qoute or no more input is available (considered a failiure).
# Note 3. Only the "" representation of a literal quote is supported.
# Note 4. setcsv will probably missbehave if sep used as a regular
# expression can match anything else than a call to index()
# would match.
BEGIN { FS=SUBSEP; OFS="|" }

Since I cannot find a ffmpeg build that will automatically include a environment variable for the CMD ffmpeg command I'll probably have to do it myself.
However I would like to do so by saving it inside a .reg file.

strtok
STRTOK(3) BSD Library Functions Manual STRTOK(3)NAME
strtok, strtok_r -- string tokens
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
char *
strtok(char *str, const char *sep);
char *
strtok_r(char *str, const char *sep, char **last);
DESCRIPTION
This interface is obsoleted by strsep(3).
The strtok() function is used to isolate sequential tokens in a null-terminated string, str. These tokens are separated in the string by at
least one of the characters in sep. The first time that strtok() is called, str should be specified; subsequent calls, wishing to obtain
further tokens from the same string, should pass a null pointer instead. The separator string, sep, must be supplied each time, and may
change between calls.
The implementation will behave as if no library function calls strtok().
The strtok_r() function is a reentrant version of strtok(). The context pointer last must be provided on each call. The strtok_r() function
may also be used to nest two parsing loops within one another, as long as separate context pointers are used.
The strtok() and strtok_r() functions return a pointer to the beginning of each subsequent token in the string, after replacing the token
itself with a NUL character. When no more tokens remain, a null pointer is returned.
EXAMPLES
The following uses strtok_r() to parse two strings using separate contexts:
char test[80], blah[80];
char *sep = "\/:;=-";
char *word, *phrase, *brkt, *brkb;
strcpy(test, "This;is.a:test:of=the/string\tokenizer-function.");
for (word = strtok_r(test, sep, &brkt);
word;
word = strtok_r(NULL, sep, &brkt))
{
strcpy(blah, "blah:blat:blab:blag");
for (phrase = strtok_r(blah, sep, &brkb);
phrase;
phrase = strtok_r(NULL, sep, &brkb))
{
printf("So far we're at %s:%s
", word, phrase);
}
}

The strtok() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

Based on the FreeBSD 3.0 implementation.
BUGS
The System V strtok(), if handed a string containing only delimiter characters, will not alter the next starting point, so that a call to
strtok() with a different (or empty) delimiter string may return a non-NULL value. Since this implementation always alters the next starting
point, such a sequence of calls would always return NULL.
