[Flac] [Flac-dev] Cue sheets/Tagging question

Hi Neil,

I think you have a misunderstanding or two.  What you want to do does  
not require "code."  In fact, you might want to move your question  
from the FLAC-Dev list to the FLAC (User) list.  I'm on both lists,  
so I did not realize that you were basically asking in the wrong  
place.  No "coding" skills whatsoever are required to create  
seekpoint markers in a FLAC file.

Anyway, FLAC has a command-line program for maximum portability  
across multiple platforms.  While it may seem almost as complicated  
as "coding," using the command-line is not nearly the same level of  
difficulty, although it is not familiar to the average computer  
user.  On Mac OS X or Linux, you access the flac command-line from  
Terminal.app or some other shell program.  I'm not sure about  
Windows, but you would probably use Command.com for access.

Again, if you read the documentation for the command-line program  
that is the core of all FLAC support, then you will find argument  
options to specify --seekpoint markers, and you should be able to  
easily create one per "track."  Unfortunately, I do not know of any  
fancy GUI front ends for FLAC which offer this feature, but none of  
the GUI front ends come from the main FLAC project anyway.  Most of  
the FLAC GUI programs are based on an out-of-date version of the flac  
command-line, and they do not offer access to all features.  For that  
reason, I use the command-line flac program exclusively, because I'd  
rather not bother with learning the deficiencies of the GUI programs.

In order to get full access to all FLAC features, you need to learn  
how to access a command-line on your computer, and run the flac  
command-line tools.  Once you learn how to do this, adding your own  
custom seekpoint markers should be dead simple.  All command-line  
FLAC options can be discovered on the command line by using the -- 
help option.  On the Mac, you might even be able to use Apple events  
to script this so that creating each new album will be fairly easy.
