Something went wrong while previewing this file

[giorgio1]

The message appears when I try to preview .ogg files containing Opus encoded audio.

The message appears both from the android Dropbox app and the Dropbox web app (I'm using Google Chrome on Linux)

Those files play perfectly locally, on every OS i tried (Linux, MacOS, Windows, and Android), usig VLC (VideoLAN Client)

Are those type of files supported by Dropbox? If not, will they eventually be supported? And if so, when?

Thank you.

It should preview as an audio file as long as its below 1gb: https://help.dropbox.com/files-folders/sort-preview/file-types-that-preview

The files I'm trying to preview are well below the 1 GiB limit.

A typical mediainfo(1) textual output for one of them is the following:

I'd suggest sending that in to www.dropbox.com/support so the team can look at it @giorgio1

I will apply. Thank you.
