That missing n could indicate some non-printing control char in your input file. Sure there's none? How did you create that file?


If you need the colons in your input file escaped, you could use

- "process substitution" for your input file, like done < <(sed 's/:/\\:/g' duration)
- "parameter expansion" for the COL2 variable, like inserting COL2=${COL2//:/\\:}; before the ffmpeg command.

curl_easy_escape

curl_easy_escape(3)						  libcurl Manual					       curl_easy_escape(3)

NAME

       curl_easy_escape - URL encodes the given string

SYNOPSIS

       #include <curl/curl.h>

       char *curl_easy_escape( CURL *curl, char *url, int length );

DESCRIPTION

       This  function  converts  the  given input string to an URL encoded string and returns that as a new allocated string. All input characters
       that are not a-z, A-Z, 0-9, '-', '.', '_' or '~' are converted to their "URL escaped" version (%NN where NN is a two-digit hexadecimal num-
       ber).

       If the length argument is set to 0 (zero), curl_easy_escape(3) uses strlen() on the input url to find out the size.

       You must curl_free(3) the returned string when you're done with it.

AVAILABILITY

       Added in 7.15.4 and replaces the old curl_escape(3) function.

RETURN VALUE

       A pointer to a zero terminated string or NULL if it failed.

SEE ALSO

       curl_easy_unescape(3), curl_free(3), RFC2396
