epub to mobipocket

tibiafry · 04-06-2009, 06:03 AM

Hello, I need to know some things:

1. What program does Calibre use to generate mobi? It doesn't seem prcgen/mobigen to me.

2. How can I avoid to create "Table of contents" at all. It's added at the end and I don't want it to exist.

3. Can I code a DRMed PRC? With Mobipocket creator it's an option called "Content Encription with DRM" and with mobigen it's an argument called "-s2".

Thanks a lot!

Calibre does not use MobiPocket code to generate MOBIs. It also does not add or subtract DRM.

If you prefer Calibre's ePub to MOBI capability, then one work around might be to use mobi2oeb to explode the Calibre MOBI. Then remove the toc.ncx (since you don't want a TOC, note that you will also need to edit the .opf file to remove references to toc.ncx). Then use MobiPocket Creator or mobigen on the .opf file to make your final MOBI. I have not tried this, but the intent is to maintain the superior ePub to MOBI capability of Calibre but still get a DRMed MOBI. Otherwise, you could just give the ePub to mobigen directly.

Indeed, conversion (epub->mobi) with Calibre is far superior to mobigen, that's why I like it. The format is respected more strctly. Not to say the same thing with mobigen, that works very well, but it's not perfect.

I've tried that workarround this morning, just testing here and there, but the result is worse than directly converting with mobigen from epub. Format is lost in the opf-> mobi conversion.

thanks for your help

Why do you want to go from DRM free ePub to DRM infected Mobipocket?

If you answer my question maybe I'll answer yours. LOL.

Use mobi2oeb from calibre to convert the calibre produced MOBI file to an OPF and then run mobigen on the OPF

It doesn't work well. The result is worse than directly converting with mobigen from epub. Format is really messed up during the opf-> mobi conversion.

Why though do you want not to have one? Most people seem to insist that one be present.

If the reason is that you already have an in-line TOC, you can extract/generate/provide an OPF file for your source and add a //guide/reference of @type="toc" pointing to your existing in-line TOC. That will prevent a new one from being generated.

Nope. DRM is evil, haven't you heard?

Not all devices read ePub files, so having an easy way to go from a DRM free ePub file to a DRM free Mobi file would be helpful for some of us.

I have my own Idex, yes. And I don't want to get a TOC, because I want my index to be like I made it. Also I want it in the specific place I put it. I didn't understand quite well the "@type=toc" thing. Can you explain it a little easier, please?

About DRMs... I'm not discussing about the goodness or evilness of it. I just need them on.

It discusses the use of "Guide Items", including the TOC.
