M4B to MP3 (chapter separation), Converting M4B to multiple MP3s taking into account the M4B chapters Options

[jaime11]

Hello
I have been searching on the forum but haven't found anything. Basicly what I'm looking for is a program that will input a M4B file and output several MP3 files (1 MP3 per chapter in the M4B file).
I have been using Free M4B to MP3 Converter, but unfortunately, all it does is extract a single MP3 from the M4B.

Anyone knows any other programs for this job?

Thank you

No problem, I'm glad it worked.

I needed a few more features for myself so I'll release them as v0.5. Changes:

• More advanced encoding options
• Drop multiple m4b files onto m4b.py

I also cleaned up and simplified the code which means m4b_half and those modifications will need some changes. But you can safely skip this one if you already have the previous version and don't need the new features. The only thing left on my TODO is making the script work with more python versions than 2.7 but this has a low priority.

First off, many thanks to valekhz for building this tool. There is only one other program out there that I found (Bigasoft Audio Converter), but it doesn't have command-line support and so this tool still reigns supreme.

In hopes that valekhz is still open to tweaking the tool, I ran into one problem. For some reason, the tool crashes on The Economist podcasts with this message:
Traceback (most recent call last):
File "C:\Programs\Python27\m4b.py", line 337, in <module>
main()
File "C:\Programs\Python27\m4b.py", line 334, in main
split(args, log, output_dir, encoded_file, chapters)
File "C:\Programs\Python27\m4b.py", line 290, in split
chapter_name = unicode(chapter_name, 'utf-8')
UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 0: invalid start byte

Here is an example file I tried to split: http://dl.dropbox.com/u/19007038/13%20Inte...C%20The%20E.m4a
(I know it's an m4a extension, but the same issue happens on m4b's)

Thanks to valekhz or anyone else who can help with this!

Many thanks to valekhz! Note for customers. Valekhz's script is working fine. If smtg not work follow instruction from begin or see run options.

On Ubuntu 12.04 you just run in terminal in any folder:

sudo apt-get install python2.7 ffmpeg libavcodec-extra-53 mp4v2-utils libmp4v2-dev libmp4v2-2 git
git clone https://github.com/valekhz/m4b-converter.git
cd ./m4b-converter
python m4b.py --no-mp4v2 PATH_TO_YOUR_M4B_FILE_ABSOLUTE_OR_RELATIVE_FROM_NEW_DIR_m4b-converter

--no-mp4v2 works for me

Valekhz's script is working fine.

And soon i found problems with unicode filenames on linux. I fix it, but then i found that it's looks like already fixed in Ramovsky's branch:
