Chapter & Verse and Rockbox

[Peak]

Hello!

Have been searching for this problem, but haven't found the answer so I thought I'll try to ask it here.

I buy a lot of audiobooks, and prefer to have them in m4b (aac) format due to the chapter support and audio quality.

I have some problems on my Sansa Clip+ and aac, though.

When I batch convert files, I usually use Audials, and the resulting files works on Rockbox, but if I remux it through Chapter & Verse to add chapters and metadata, the files stop working on my Sansa. Likewise if I convert directly through C&V (it shouldn't have anything to do with the converting due to the fact that C&V uses iTunes for converting. So there must be something about stream- och metadata that Rockbox doesn't like. (The files do work on the computer & my android player)).

Excessively complex MP4 streams won't be parsable, due to a combination of software limits in our parser and limited memory available for storing the complex header data required for various MP4 features.  If you want to use complex MP4 features, its best to stick with a PC or at least a more advanced mobile device like a tablet that has a lot of memory.

You can achieve this using an mp3 and cue file.

The offset & chapter name can be encoded within the TRACK INDEX/TITLE fields.

The cue file can then be embedded within an ID3v2 TXXX CUESHEET tag.

Code: [Select]

eyeD3 --set-user-text-frame="CUESHEET:`cat example.cue`" example.mp3

I personally use 64kbs CBR mono for mp3 audiobooks and find the quality excellent.

You could also use this approach with Ogg or Speex and a CUESHEET Vorbis comment.
