Calibre Progress Sticks At 47 per cent

wizilinx · 12-02-2014, 01:21 PM

Hi

I have been working on a document for quite a while. Calibre has been excellent. All of a sudden it will not convert epub to mobi. It sticks at 47% progress. I read on the forum just let it run but it has been running for 2 hours and it is still at 47%.

I converted the epub using KIndlegen but I really want Calibre to work again. I really would welcome some advice. I cannot go and start deleting images and all the kind of stuff. This book is already published and any editing is a risk. I was only making minor but essential changes.

PLEASE PLEASE HELP

Cheers
Jon

Conversions have been know take 24hours or more to complete - conversion is a multi-pass stepwise process, the progress percentage is indicative only.

Let it run, it will eventually finish.

If it is the same document that NOW takes forever,:

You did something that made a significant code change to the complexity.

CSS/style Code changes might be tiny, but have huge impact to the complexity of the rendering.

Really appreciate the reply...

Well it has been running for 36 hours so far and no change. I have a really fast computer.

Interestingly I tried an old epub that converted no problem before and it has the same problem. So to me it seems a problem with Calibre.

Kindlegen works.

If anything my last change was to emit CSS on a couple of paragraph styles in InDesign.

Surely there is a bug?? I cant wait for days for a conversion..

I repaired the library it said there were no problems..

I would love a work around. As this is currently unusable.

Cheers

This will almost certainly be because you have InDesign set to produce fixed layout HTML in the EPUB, which means it generates endlessly repeated and redundant CSS, for every small span of text, which will take forever to convert.

Hi

Thanks for your answer. I don't recall making any changes to my document in inDesign like this. All I did was change my logo and a bit of text (and one slight change to a paragraph style) - The latter seeming the most dangerous according to your answer. I think I noticed it was producing CSS and I switched it off..

I exported the same as I always did.

Also as I said a previously used epub that converted to mobi stopped working too...??

Also, why do KindleGen do a better job (only in the respect it doesn't hang?)

I will have to research why it has produced fixed html (what this means) and what settings I can use in Indesign to stop this problem

Can you point me to some further information. I personally know what CSS is and where possible I switch it off - cause I don't know how to use CSS - and I dont want to either.. LOL

I have no idea, I dont use InDesign. I have seen InDesign produced EPUBs that are fixed layout and have tons of CSS which therefore take a much longer time to convert, so since I have not seen your EPUB, I am guessing it is one of those.

As for why kindlegen performs better, it's because it does much less than calibre. calibre produces MOBI files that look good from a far alrger colelction of input documents than kindlegen.

Thanks.. Well that helps but I still have to work out why so much css gets attached to the epub in InDesign

By the way this is not "fixed layout" it is "flowable layout" - so even more confusing I suspect..
