Epub repeating text (Ibook) Ipad
I have a recurring fault in my Media Overlay for a Fixed-layout Epub.
It seems to be random, but not completely... There are several places in the book, where it (almost) always repeats the audio while re-highlighting the same text over and over. I´m using the Ibooks reader on ipad for testing and the epub has both sound (a media overlay specified in a .smil file controlling the mp3 audio files) and 2 different types of animations (indesign exported animations and Gif´s). Both sound and animation work perfectly when using Ibooks on my laptop, but on the ipad it repeats certain pieces of text... Any suggestions? (see pictures for screenshots) This is my first time posting this forum for help, so any recommendations to clarifying the issue will go a long way.

This is my first experience with .smil files, so have no idea how they used to work, but you can encase the smil part in a div/ID and point it to your <p> tag to target the whole paragraph. Sadly it´s not without glitches, as I am currently struggling with, and I am still searching for a solution Last edited by marcfaaborg; 10-08-2018 at 02:32 AM. |

The examples you posted, are those the places where it repeats? You said it's not that random? Hitch |

The first div on the xhtml (page 2 in the document) with "id="k1_11", is where it usually starts to repeat itself. Even though it usually manages to get through without repetitions on page 1 - if I turn back the page, it will now also do repetition mistakes on page 1... After that it seems to begin a vicious cycle, where it just gets worse and worse - sometimes it repeats the same div or p tag 5-8 times... Very frustrating |

@marcfaaborg: AFAKI, the iOS version of iBooks has limited SMIL support. For example, it won't play the perfectly valid epub3 audio books by ReadBeyond.
If you're able to distribute your book without DRM, you might be able to use the free iOS/Android Menestrello apps, which have much better SMIL support than iBooks. (BTW, the developer, Alberto Pettarin, is an MR member.) |

I think that the sentence-level SMIL support is basically non-existent. I think that they think, "well, yah, embed it if you want, but...you (don't) pays your money, you takes your chances" kind of thing. Who is it here...Hmmmm...does a lot of SMIL work? It's...crappity. I can't think of who it is, but he...St. Albert? Is it Albert that does all the SMIL? Anyone remember? If anyone would know, I think it would be him. My SMIL/readalong experiences, thank God, are in distant memory, as most of my clients realized...well. Distant memory, let's just leave it at that. Hitch |

Hi Doitsu. You´re right about Menestrello! A collegue of mine helped me test it, and it reads the .smil file perfectly, but only single page and sadly not as popular as the blasted Ipad The part that really annoys me though is: My epub works perfectly in Ibooks on my macbook laptop, but doesn´t on a brand new Ipad with newest IOS. |

Issue Resolved
I'm 99% sure we (I'm @marcfaaborg's coworker) resolved the Issue! I'll be 100% when the last page of the book has been tested. The issue is a bug in iBooks requiring you to have a SMIL-file for every EPUB Content Document. At least, from my reading of the media overlay spec.
We went trough every possible feature that could have an impact on the rendering. Stripping out first CSS animations, JavaScript and everything but the essential HTML-structure of the pages. But the bug was still there. Trying out 2 different timestamp formats and splitting the SMIL-files to represent a single .mp3 (chapter) didn't work either. It only worked when I split the SMIL files into 1 for every .xhtml and only containing one <seq> element in the document. The timestamps still represent one line of text so it is possible to do unlike what was speculated. When the books is completely finished and tested I'll update this post. Update: This was indeed the issue. The Media Overlay works as intended. I'll go ahead and report this as a bug to Apple. Unless omebdy knows that we interpreted the Media Overlay spec wrong, by creating only one file for the entire media Overlay. As an aside: Quote:
