I'll try the latest release (1.15.0.6) and let you know
Yes, with version 1.15 it works but only when using ?dl=1. Unfortunately, this way the file is downloaded and saved inside the epub file, which is what I do not want. If I wanted to include files in the epub I would save time and use local files. I'm using external files because I want to stream the audio and keep the epub file size small.
Now, I need to understand if the streaming doesn't work because of pandoc or because of dropbox.
Let's try a regular path file on a server, see file attached:
pandoc downloads the file and includes it in the epub. Why?
HTML output does not include external resources by default and you can include them with option --self-contained. IMO epub output should work the same. Is it a bug or a design decision?
