Help with downloading ebooks into Marvin using Calibre content server vs OPDS

[deadman36g]

I have been trying to solve a problem I keep having and am needing some help.

Some of the ebooks I have have generic covers by default but I have added a nice cover using Calibre (saved as cover.jpg in the books folder)

I do not like to change anything about my actual epub file as I like to keep them as retail quality.

Ok, I am using Marvin for iOS as my ebook reader, and when I download the ebooks using OPDS they do not get the cover from Calibre they get what I guess is the default cover.

When I do the Connect/Share button inside Calibre and download that way, I do get the books with cover art


The only problem is, this solution requires Calibre to be running at all times and that is not ideal for me.

I have included a video to help explain my problem

the only way you will get this to work is if you use the option to embed the updated cover/metadata in the eBook file (i.e. Changing it). It works when you use the Connect button in Calibre as that change is made as part of the transfer.

Ok, is it possible if later I wanted to undo that option and make the file unchanged again? (i.e. restore orginal, or remove any embedded data from calibre)

If you're converting like-to-like (e.g. EPUB to EPUB) or using Polish books you could change the settings in Preferences->Tweaks->Save original file when converting/polishing from same format to same format to True.

Then when you convert EPUB to EPUB, or polish an EPUB, you will have an ORIGINAL_EPUB file. The right click menu on the ORIGINAL_EPUB in Book Details (afaik there is no other way) will have an option to Restore the ORIGINAL_EPUB format.

IIRC - if you do another EPUB to EPUB conversion or Polish it will do it on the ORIGINAL_EPUB. The feature is not intended to be used as a means to keep a 'safe' copy of the original format in perpetuity. Its purpose is to provide a means to undo the results of an unsatisfactory like-to-like conversion or polish. If the conversion or polish is acceptable it is assumed the user will remove the ORIGINAL_XXXX format.
