Audio book: Only the first 255 chapters are shown
I have an audio book with 391 chapters in m4b format. I can access and play these chapters individually with ffplay. ffprobe also confirms that these chapters are available. When I open the audio book in VLC, only the first 255 chapters are displayed under "Playback, Chapter". Also the visual markers in the timeline end at 255. Even with the shortcut shift + n only these 255 chapters could be accessed.
I am unable to upload an audio book for testing. To be able to offer a test anyway, I have used a YouTube playlist (https://www.youtube.com/playlist?list=PLzCxunOM5WFLNCSF0UEHZqFJJlmdeL71S) with free music. In this example 300 free songs were used, each song represents a "chapter". Instead of 300 only the first 255 are shown.
