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.

XHPInputISO7sub(3X)													       XHPInputISO7sub(3X)

NAME

       XHPInputISO7sub - map keysyms into ISO 7-bit substitution characters.

SYNOPSIS

	int XHPInputISO7sub(display, keysym, modifiers, buffer_return, bytes_buffer, status_in_out)
	    Display *display;
	    KeySym *keysym;
	    unsigned int modifiers;
	    char *buffer_return;
	    int bytes_buffer;
	    XComposeStatus *status_in_out;

DESCRIPTION

       display	      Specifies the connection to the X server.

       keysym	      Specifies the keysym that is to be converted into an ISO 7-bit substitution character.

       modifiers      Specifies the modifiers to be applied to the keysym.

       buffer_return  Returns the translated characters.

       bytes_buffer   Specifies the length of the buffer.  No more than bytes_buffer of translation are returned.

       status_in_out  Specifies the XComposeStatus structure.

       XHPInputISO7sub will convert keysym into a ISO 7-bit substitution character, if appropriate.  This routine will also process the control
       modifier.  The return value is the length of the string returned in buffer_return.  This routine is intended to be used in conjunction with
       XHPConvertLookup.

       status_in_out is used to hold the information necessary to perform 7-bit substitution input.  This structure must contain null values
       before this routine is first invoked, and must remain unchanged between uses.

       XHPConvertLookup and XHPInputISO7sub are provided for backwards compatibility only; these routines will be discontinued in a future release
       of HP-UX.  The operating system provides no direct support for processing ISO 7-bit substitution characters.  Users of ISO 7-bit
       substitution character set should migrate their data to a supported 8-bit encoding, such as ISO 8859.1.	Additionally, users desiring the
       same capabilities as those provided by these routines should use XOpenIM, XCreateIC, and XmbLookupString.
