Art Work is not displayed in Audiobooks (m4b)

[yermak 1]

Version 3.5.3.0

OS: Ubuntu 18.04.1 LTS hosted in Hyper-V

 

I created audiobook library using Books type for NFS mounted directory with books in m4b format. (NFS is shared from ReadyNas)

Books are displayed and i'm able to play them via Chrome and IOS app.

 

ArtWork (visible in iTunes) is not displayed for most of the m4b: niether in chrome nor in IOS app.

The only ArtWork is visible is when m4b has more then 1 video stream, which is used for ArtWork. (Those were actually created by mistake).

 

 

 

For files with single video stream (as it should be normally)

 

 

This is confirmed by multiple sample, all audiobooks with 2 and more posters are visible, with one regardless if it's mjpeg or png stream are not visible.

I tried to do full rescan of the library - no result.

 

P.S. Sorry, my audiobooks in Russian, not sure if it causes an issue.

Hi there, can you provide one of these files for testing? thanks.

I will create smaller version and share the link.

BTW, found source code, so more likely will debug myself first.

On the beta we get an extraction error.

Great, thanks, we're looking into this.

[yermak 1]

Luke,

thank you!

 

As I understand there is ongoing work on improvement of Books type atm.

Are those improvements included in current Beta?

[Luke 39306]

Yes they are.
