[GUI Plugin] AudioBook_Duration

The ones showing up wrong are always shorter (usually much shorter) than the actual length of the audiobook. I'm attached one example (and linked it from imgur), but this isn't my only incorrect one.

top line is info from calibre showing incorrect duration
bottom line is from file explorer showing correct duration

When I have audiobooks in multiple parts, I merge them together into one file using Merge MP3, so my first thought was there was a metadata holdover from before merging. However, I've had this issue happen in audiobooks that did not need to be merged and there are audiobooks that I've merged that don't have this issue at all.

Any thoughts on fixing this?

Hello, it could be many things.

But we are going to test the most common problem, that the audios have a wrong file extension.

Maybe not all the parts were originally mp3?

You can try a program to check the real codec of the audios, like "MediaInfo" https://mediaarea.net/en/MediaInfo
(also for android and ios looking in their markets)

If the file extension is incorrect, mediainfo recommends compatible file extensions.

For example, this is an mpeg audio layer3 (mp3) file but I renamed it wrong to .ogg, when I open it with mediainfo it recommends the proper extensions.


P.S: If this doesn't fix your problem, we could try other ways

To my knowledge, they were all mp3s (except for a few that I converted with VLC, and I believe those are all fine).

I added a screenshot of the info from the program you recommended. I'm not entirely sure what I'm looking at here, but it's not telling me that the extension is wrong:



But it's also showing the wrong duration on that screen.

Hello, we already know something else.

It tells us that it looks like a correct mp3, but something is wrong in that resulting file or in its metadata, since it also indicates 1h of duration.

How did you join the audios?

The AudioBook_Duration plugin can calculate the duration of all files inside the folder or even .zip or .rar file

If it calculates the duration of the original audios correctly, we have to see what has happened when converting them to a single file.

Hi All!

I think I have followed all the directions correctly.

Installed plugin.
Created column for duration (named duration) and set type as "Text, column shown in the tab browser."
Configured plugin with "#duration" in the customize window.

When I click "update the audiobook duration column" it calculates then tells me "updated duration column in 1 book(s) file."

Nothing appears in the duration column.

Please help me figure out how to fix this. I'm using Calibre Portable on Windows 10.

Hi,
Please review the column name and the column name that you put in the configuration.

Indeed, if the name of the column is not exactly that of a valid column, it shows the message that the data has been updated, but since that column DOES NOT EXIST, it cannot update them.

Could you show a screenshot of the custom column and settings, something like that...

[theducks]

do not include the # WHEN YOU CREATE the column.

It is needed when you configure apps or searches .

[LazyGirl]

Here are the pertinent screenshots. I only entered # in the Customize Audiobook_Duration window. Calibre added it to the column list.

Hi LazyGirl,
As i can see in your screens, i think Calibre is case sensitive and you should use "#duration" instead of "#Duration"

I love this plugin, but I've run into a problem. It will calculate the duration properly if the audio files themselves are stored by Calibre, but if I make an .m3u or .pls file (with absolute paths) for multi-file audiobooks and place that alone in Calibre, while leaving the audio files in a different directory, it returns a value of 0:00:00. Is there a way to get it to actually parse the playlist files so it can find the actual audio files to calculate the duration?

Moving the files into Calibre isn't a viable solution for me — I use AudioBookShelf to stream my audiobooks, so the files need to be in a specific directory for it to find them — but I do like to track all information about a book, including a playlist link to it, in Calibre.

TIA!

Audiobook Duration only calculates the audios inside the caliber folder.

Currently does not look for paths inside .m3u or .pls files or other files.

Maybe your instalation of Calibre had something wrong, try unisntalling and installing again, as i can see:

File "calibre\customize\zipplugin.py", line 307, in load
File "importlib\__init__.py", line 126, in import_module

This 2 lines, seems that Calibre can't load correctly importlib and zipplugin, and you need them to install plugins and load imported libraries.

[MishoCana]

Thank you. I will wait till the next version release.

This was the problem! Thank you so much wiso!!!

[TomboAhi]

I am having an issue where it constantly reports each and every folder as being opened in another program. It could be after a clean boot, no other apps open, and it does not matter where the folder is located. Same error each time. Even with a single MP3 in the folder.





Might you have any idea on what the problem is?

Thanks in advance.
