Feature Request: Be able to download parts from Audible rather than whole books?

[digital-night]

Hi, I love this project, but when using it I get this message on some of my books:

error: Error downloading [redacted].aax. Wrong content type. Expected type(s): ['audio/aax', 'audio/vnd.audible.aax', 'audio/audible']; Got: text/html;charset=UTF-8; Message: This title is not supported for full audio file download, please download individual parts.

Looking online I can see a few people mention that they have run into this. Is it possible to add the ability to download the files as parts and combine on the machine once all parts of been fetched? I've also had cases where the download gets interrupted before the entire book is downloaded, and I suspect if I could fetch and compile the parts that would make it more efficient to recover from failed downloads.

Thank you for your feature request.

Yeah I can add the feature to allow downloading audiobooks in parts if necessary. You are willing to test this when it is ready?

Another feature on my todo list is to continue paused downloads. Do you have any knowledge in Python programming to realize this step?

@digital-night
If you want you can try this branch for testing the resume download function.

This will currently only work for aaxc files.

How it works:
If an aaxc download aborts (e.g. CTRL+C, Internet Connection Reset) the temp file will be kept in the download directory. If you run the download command again, the temp file will be reused and audible-cli will download the missing content.

Do you have an asin from a book which have to downloaded in individual parts? I'll fix this but I need further information about content size and other things.

Thank you for this great tool. I have the same problem with some of my books only available as part downloads. For example this one: 3837144054: Brandon Sanderson: Die Sturmlicht-Chroniken: Der Ruf der Klingen

If you could fix that problem it would be much appreciated. Happy new year!

This and the resume download feature requests are next on my todo list. I'll take a look into the asin you are providing. Maybe I'll can give a first PR this week!

PS:
Ich wünsche ebenfalls noch ein frohes und gesundes Neues Jahr.

I've created this which should support downloading audiobooks in parts automatically. Maybe you can test these out?

[mkb79]

All parts of your audiobook are all released at 2200-01-01T00:00:00Z. That are the publication_datetime values from the API response. The publication date is verified by audible-cli and will raise if not published. It's possible to override this behave. But this could lead in some circumstances for audiobooks which are really not published.

@Marzl7
You can now reinstall from branch again. Downloading in parts should now works. It did for me using your asin.

@mkb79
Yes! Thank you its working great know.

Great to hear that. Should I include an option to force the download in parts, if possible? Or is a single file (even if it is large) the better way?

PS:
Thank you for your support! I am very grateful for that.

[Marzl7]

I prefer the single file option when it's possible, makes it way easier to convert. But adding options is always good maybe someone needs the books in parts.
