Problem converting LDS MOBI file to ePub with Calibre 0.7.29

[jbennion]

I am trying to use the LDS scriptures on my Sony Reader PRS-650. There is a version someone else did that doesn't use the links or touchscreen feature, but this version is much better if you do have a touch screen, which I do.

The problem is it isn't converting correctly. When I convert it, all the links fail and I can't page past the first page.

Even the basic viewer has a problem with displaying this file, it takes hours and hours before anything will display. Though the latest Mobipocket reader (and prior versions) pull it up quickly and just fine.

The file is attached below.

The conversion job did finally fail. Here is the log file output:

MemoryError

[Manichean]

MemoryError means that the process is out of physical memory. You'd need to install more RAM, I think.

[jbennion]

Yeah it ran out of memory after running for more than 18 hours. The file isn't THAT big. I was hoping that something prior in the logs would have indicated what would cause the process to hang.

[Manichean]

The only mildly remarkable thing is that Calibre notices that the markup (XHTML or whatever lies underneath a mobi file) seems to be somewhat screwy and wants to correct that. I have no idea in what way that influences memory consumption, though.

[kovidgoyal]

That's a memory error in the huff/cdic decompression code. That code is very rudimentary (based on an initial reverse engineering of the algorithm, and as there aren't a lot of books in the MOBI format that use Huff/cdic, I've never bothered to polish it). I'm afraid that's unlikely to change, as the amount of effort this would entail is not worth it, IMO.

In an effort to help the Kindle community I have converted most church materials into the native MOBI format. All are free and available for download here.

Perhaps someday the church will have an official app for the Kindle Touch but in the mean time you can get all the content here.

I hope everyone finds this useful.
