How to properly implements audiobooks on the TestApp?

[morismoris]

I would like to test audiobooks on the testApp.
I started from the 'main' branch.
I made these small changes that I report below, but the audio is not reproduced even if the log says that the player remains in the 'playing' state.

In the "presentPublication()" of "ReaderModule" if publication.metadata.type == "https://schema.org/Audiobook" then I open my AudioViewController

This ViewController which provides a simple audiobook interface has the following code:

import UIKit
import R2Shared
import R2Navigator

class AudioTestViewController: UIViewController {

  var publication: Publication!
  var audioNavigator: _AudioNavigator!
  
  deinit {
      audioNavigator.pause()
      audioNavigator = nil
  }

  override func viewDidLoad() {
      super.viewDidLoad()
      audioNavigator = _AudioNavigator(publication: publication)
      audioNavigator.delegate = self
      audioNavigator.volume = 1.0
      audioNavigator.play()
      print ("---> playbackInfo: \(audioNavigator.playbackInfo)")
      print ("---> state: \(audioNavigator.state)")
  }

}

extension AudioTestViewController: _AudioNavigatorDelegate {
  func navigator(_ navigator: Navigator, presentError error: NavigatorError) {
      print ("---> presentError \(error.localizedDescription)")
  }
  
  func navigator(_ navigator: Navigator, locationDidChange locator: Locator) {
      print ("---> locationDidChange \(locator.json)")
  }
  
}

The log I get is this:

[INFO] GCDWebServer started on port 57389 and reachable at http://localhost:57389/

@morismoris Could you share the .audiobook file used in your tests? You can share it privately on Slack with me if it's copyrighted.

[morismoris]

I uploaded the file (must be unzipped). it’s only a sample with three chapters.
DivinaCommedia_Inferno.audiobook.zip

[morismoris]

Could you take the test with the audiobook I passed you (but I don't think the problem is related to the specific file)? Is there any news?

[mickael-menu]

Yes, I believe the issue is that you are adding the audiobook to the local HTTP server, here:

swift-toolkit/TestApp/Sources/Library/LibraryService.swift

Line 114 in b4a9358

try publicationServer.add(publication)

This should be done only for EPUB, PDF and CBZ files. We're looking into a way to remove the HTTP server entirely.

[morismoris]

It works! Thanks a lot!

Now, I add the publication only if
publication.metadata.type != "https://schema.org/Audiobook" && publication.metadata.type != "https://schema.org/CreativeWork"
