-If the chapter truly is empty, that is, 0 audio frames in length, then yes it is ignored.
-If the chapter is shorter than 3 seconds long but still has some audio frames, those frames are combined with the following chapter and not split into a new file.
-
-I also implemented file naming by chapter title. When 2 or more consecutive chapters are combined, the first of the combined chapter's title is used in the file name. For example, given an audiobook with the following chapters:
-
-00:00:00 - 00:00:02 | Part 1
-00:00:02 - 00:35:00 | Chapter 1
-00:35:02 - 01:02:00 | Chapter 2
-01:02:00 - 01:02:02 | Part 2
-01:02:02 - 01:41:00 | Chapter 3
-01:41:00 - 02:05:00 | Chapter 4
-
-The book will be split into the following files:
-
-00:00:00 - 00:35:00 | Book - 01 - Part 1.m4b
-00:35:00 - 01:02:00 | Book - 02 - Chapter 2.m4b
-01:02:00 - 01:41:00 | Book - 03 - Part 2.m4b
-01:41:00 - 02:05:00 | Book - 04 - Chapter 4.m4b
-
-That naming may not be desirable for everyone, but it's an easy change to instead use the last of the combined chapter's title in the file name.

-.SYNOPSIS
-    Downloads, decrypts and repackages content from Hoopla
-
-.DESCRIPTION
-    Uses a HooplaDigital.com account to download DRM-free copies of ebooks, comics,
-    and/or audiobooks available on the platform. Content that is not already borrowed
-    on the account will be borrowed if slots are available. Content that is not borrowed
-    cannot be downloaded.
-
-    * E-Books are downloaded to epub files (most) or cbz (rare, picture books).
-    * Comic books are downloaded to cbz files.
-    * Audiobooks are downloaded to m4a files. (single file, and very little metadata available
-      from Hoopla, such as chapters)
-
-.PARAMETER Credential
-    Credential to use for logging into Hoopla site.
-    (Cannot be used with Username and Password parameters)
-
-.PARAMETER Username
-    Username to use for logging into Hoopla site.
-    (Cannot be used with Credential parameter)
-
-.PARAMETER Password
-    Password to use for logging into Hoopla site.
-    (Cannot be used with Credential parameter)
-
-.PARAMETER TitleId
-    Specifies one or more title IDs of content to download.
-
-.PARAMETER OutputFolder
-    Sets the output folder for downloaded content. Defaults to current directory.
-
-.PARAMETER PatronId
-    Override default patron id for Hoopla. (This is rarely required as most user accounts are only tied
-    to a single patron).
-
-.PARAMETER EpubZipBin
-    Specifies path to epubzip binary. Else look for one beside script, or in system path.
-
-.PARAMETER FfmpegBin
-    Specifies path to ffmpeg binary. Else look for one beside script, or in system path.
-
-.PARAMETER KeepDecryptedData
-    If set, don't delete the intermediary data after decryption, before final output file.
-    For ebooks, this is xml, images, and the manifest. For comics, it is images. For audiobooks,
-    it is mp4 ts files. This is typically only useful for development or troubleshooting.
-
-.PARAMETER KeepEncryptedData
-    If set, don't delete the encrypted data as downloaded from Hoopla's servers. This is typically
-    only useful for development or troubleshooting.
-
-.PARAMETER AllBorrowed
-    This parameter is deprecated. If TitleId is not set, it is implied that all borrowed titles will
-    be downloaded.
-
-.PARAMETER AudioBookForceSingleFile
-    If set, leave audiobook as single file, as if chapter data is not present.
-
-.EXAMPLE
-    .\Invoke-HooplaDownload.ps1 123456
-    Downloads Hoopla content with title id 123456

-From a Libation user about possibility of integrating Hoopla:
-
-I have a powershell script.  I didn't write it, and neither did the person that gave it to me.  It works most of the time (98%).  Some titles, it doesn't play well with, but does allow to keep the downloaded data, whether the decrypt was successful, or not, and then you can mess with the data, from there.
-
-If you run the script with no parameters, then all the books in your library will download, and decrypt into the same directory as the script, into a folder named Completed.
-
-If you run the script with the command:
-  '.\HooplaDownloader.newer.ps1 -KeepDecryptedData'
-then it will, and will notify you, when complete, where it was stored.
-
-There is a parameter to download a specific titleID#, whether it's in your library, or not, but I've not played with it that far, as the method to accomplish it still reserves it to your library, and then proceeds as normal.  I can tell you, if it's a "trial and error concern", the title will not be removed from your library, after you run the script, whether it succeeds or not.  So, if it fails, you can retry, or try the  -KeepDecryptedData option.  I received no documentation for it, which is why I'm telling you as much as I know about using it.
