Unable to find Metadata in ODM

[mjeshurun]

Hi friends,

I tried to download an audiobook using the python command, but I'm getting the "ValueError: Unable to find Metadata in ODM" error message.

`odmpy libby --latest 1 odmpy Interactive Client for Libby

Non-interactive mode. Downloading latest 1 loan... Opening audiobook "Pimsleur Hebrew Level 1"... Already downloaded odm file pimsleur-hebrew-level-1-390557.odm An unexpected error has occurred Traceback (most recent call last): File "/usr/local/lib/python3.9/site-packages/odmpy/odm.py", line 983, in run process_odm( File "/usr/local/lib/python3.9/site-packages/odmpy/processing/odm.py", line 135, in process_odm raise ValueError("Unable to find Metadata in ODM") ValueError: Unable to find Metadata in ODM Traceback (most recent call last): File "/usr/local/bin/odmpy", line 8, in sys.exit(main()) File "/usr/local/lib/python3.9/site-packages/odmpy/main.py", line 27, in main run() File "/usr/local/lib/python3.9/site-packages/odmpy/odm.py", line 983, in run process_odm( File "/usr/local/lib/python3.9/site-packages/odmpy/processing/odm.py", line 135, in process_odm raise ValueError("Unable to find Metadata in ODM") ValueError: Unable to find Metadata in ODM`

Is there a known fix for this issue?

Unfortunately no, there is not; we did attempt a fix but it broke, we have not been able to figure out any more.

There is a workaround documented in the comments to this bug (link goes directly to the comment in question): https://github.com/ping/odmpy/issues/69#issuecomment-2078355058

Notice that you will need to download the ODM file directly from your library's whatever.overdrive.com site (you can find that by using www.overdrive.com 's library finder).

Another quick note: you don't need to use any of the options listed in that comment. I never use merging, but I normally use odmpy dl -k file.odm because I prefer to have the cover image separate; but you don't even need -k. If you want more metadata (like what series it belongs to) and you know the Libby ID, I can give you a command line to get that.

Many thanks for the explanations, @wtanksleyjr 🙏

Hi, @wtanksleyjr

I was able to follow your instructions and download an audiobook file :)

Do you know if there is a way to open odmpy created audiobooks with the apple Books app on iOS?

I used odmpy to create a .m4b file with chapters encoded in aac, but it seems the iOS Books app cannot import it. I was able to open the file using the MacOS Books app, but not on iOS.

[wtanksleyjr]

Sorry, I know nothing about iOS. I'm not sure whether the Books app is supposed to handle audiobooks, though, is there still iTunes? I know that used to be the correct way.

Congrats on getting the rest to work though, I'm so glad the old ODM mode was left in.

I use Smart Audio, but I think its Android only. Look here... https://www.reddit.com/r/audiobooks/comments/dbkhau/any_ios_apps_handle_remote_m4b_files_properly/

I hope they get the Libby part working at some point. Whatever they did a few months ago broke the Chrome plugin and I assume the firefox plugin. With the Libby part of odmpy not working, the only way to dl an audiobook is with the old odm file, but who knows when they will kill that off as well.

Thanks to all the coders!

it it seems the iOS Books app cannot import it. I was able to open the file using the MacOS Books app, but not on iOS.

Import it into Books.app(literally drag and drop works) on MacOS and then sync the books to your phone, the phone will see them after a sync.

Thank for the tip, @birlorg . Do you know if there's a way to sync the audiobook file to the iOS Books app using a Windows based PC?

[birlorg]

I don't really know. I think you have to use the Music app to play audiobooks if you are syncing from Windows, Install the Apple Devices app, and then just move it as a music file. https://support.apple.com/en-ph/guide/devices-windows/mchl5ded2763/windows
