Unable to convert MOBI to EPUB

[bb46970]

Hi,

I have a mobi book that I added to Calibre. It took a long time to add, but it added the book, with the metadata. It shows the title, author, size (18.6 MB), etc. The book probably has 10's of thousands of links and I do not want to loose them. If I try to open it, after a very long time, I give-up, and close the window.

I was able to successfully convert it to HTML with both mobiunpack.py and mobihuff.py. I can open the resulting HTML in Firefox. However, trying to add the HTML to Calibre give mes:

calibre, version 0.8.13
ERROR: Adding failed: The add books process seems to have hung. Try restarting calibre and adding the books in smaller increments, until you find the problem book.


I tried using Calibre to convert it to EPUB, HTML, and HTMLZ. Below are the errors for EPUB and HTMLZ.

Here is the error for EPUB.

MemoryError

It's running out of memory because of your 10s of thousands of links. You probably need more memory - a lot more memory.

There's a small chance that there is some memory leak associated with the file, but you'd need to submit a bug the bug tracker for that to be investigated:
https://bugs.launchpad.net/calibre

That's a memory error in while running a regex on the html to replace html entities. There's no fix for that.

[bb46970]

kovidgoyal,

I was not able to import the HTML version. That error was from converting the MOBI to EPUB. Will more memory fix the problem? I can open the MOBI in Kindle for PC, but not Calibre. And I can open the HTML in Firefox, but I cannot add it to Calibre.

Thanks,

D.

No, the only way to use this file in calibre is to split the html into smaller chunks manually and remove most of the CSS. calibre's ebooks utilities are not designed to minimize memory usage, trying to process large chunks of HTML like this file, is not going to work.

[bb46970]

kovidgoyal,

I am trying eCub, which requires mobi2oeb from Calibre. I have the latest, portable version of Calibre, which does not seem to have mobi2oeb. Is there some place that I can download this?

Thanks,

David

As far as I know that program is no longer part of Calibre and has not been for some time. I am guessing that it dates back to the 0.6 series (or earlier) which is something like 100 releases ago. All the functionality of the xxx2yyy type programs was subsumed into ebook-convert when the Calibre conversion engine was reworked to use a plug-in architecture.
