shnsplit and flac tags

ShionjiYuuko · 2011-10-13 00:16:32

I'm trying to split a single-file flac cd rip to flac files, with tags read from cuesheet

without tagging, (simple '-o flac'), shnsplit works fine... but the help message says that it can take additional arguments for the encoder

  -o fmt  specify output file format, extension, encoder and/or arguments.
          format is:  "fmt [ext=abc] [encoder [arg1 ... argN (%f = filename)]]"

       -T FIELD=VALUE, --tag=FIELD=VALUE
              Add a FLAC tag.  The comment must adhere to the Vorbis comment spec; i.e. the FIELD must contain only  legal  characters,  terminated  by  an
              'equals'  sign.  Make sure to quote the comment if necessary.  This option may appear more than once to add several comments.  NOTE: all tags
              will be added to all encoded files.

I always failed when I try to add encoder arguments. I want to ask flac to do the tagging so that I don't have to tag the files manually

# shnsplit -f utf.cue -t "%p - %a - %n %t" -x 1 -o "flac -T TITLE=%t -T ALBUM=%a -T TRACKNUMBER=%n -T ARTIST=%p %f" After\ Eden.flac 
shnsplit: warning: discarding initial zero-valued split point
Splitting [After Eden.flac] (65:43.21) --> [Kalafina - After Eden - 01 Eden.flac] (5:40.28) :   0% ERROR
shnsplit: warning: error while transferring 60041856 bytes of data
shnsplit: warning: child encoder process 11477 had non-zero exit status 1
shnsplit: error: failed to split file

same error even without really invoking additional arguments

# shnsplit -f utf.cue -t "%p - %a - %n %t" -x 1 -o "flac %f" After\ Eden.flac 
shnsplit: warning: discarding initial zero-valued split point

shnsplit: warning: error while transferring 60041856 bytes of data
shnsplit: warning: child encoder process 11508 had non-zero exit status 1
shnsplit: error: failed to split file

is this a bug?

Do you know cue2tracks? It does the job extremely well, so you can either use it directly, or explore the code of the script for the most relevant parts.

In my experience, this is a broken .flac file that will make tools reading it stop when CRCs don't match.
I tried shnsplit, audacity, flac, they all fail.

The way out for me was to use ffmpeg to convert to other lossless format, say, wav:

ffmpeg -i the_file.flac the_file.wav

and then regenerate the flac with the reversed parameters:

ffmpeg -i the_file.wav test.flac

Splitting the regenerated test.flac worked without errors, hence my conclusion that initial flac was broken.
It's also possible to read through errors in input files with flac, instead of ffmpeg:

flac -F -d the_file.flac

This will force decoding to a wav for further processing, as above and flac will report a CRC mismatch.

Thank you for sharing that, arch_goat.

I'm going to close this now, as it's a four year old thread.
