[Bug]: DSF (dsd) files are converted to pcm by MPD when streaming via subsonic api

[GioF71]

I confirm that:

• I have searched the existing open AND closed issues to see if an issue already exists for the bug I've encountered
• I'm using the latest version (your issue may have been fixed already)

Version

0.52.0 (92a98cd)

Current Behavior

MPD will need to convert the dsf file coming from a subsonic stream url, supposedly because of the Content-Type header, set to audio/dsd. Setting it to audio/x-dsd might help solving the issue. At least that is what happened with Lightweight Music Server, see here

Expected Behavior

The stream should be reproduced in dsd mode using mpd with a dsd-capable dac

Steps To Reproduce

1. Use ffmpeg as the file scanner extractor
2. Add at least a .dsf file to the library
3. Rescan the library
4. identify the id of a dsf track using the subsonic api
5. Create the subsonic stream url for that track
6. Try to add and play the track on Music Player Daemon
7. Verify (cat /proc/asound/YOUR-DEVICE/pcm0p/sub0/hw_params that the dac is playing a dsd format

Environment

- OS:docker 26.0.0 on Debian Bullseye, arm64
- Browser: not particularly relevant
- Client: Postman, Music Player Daemon

Anything else?

In the log before, you will also find evidences of an additional client. That is mpd-subsonic-scrobbler running.

By the way, taglib extractor now supports .dsf files, as it is using TagLib 2.0.1

By the way, taglib extractor now supports .dsf files, as it is using TagLib 2.0.1

So I understand we can avoid to set ffmpeg as the scanner in order to support dsf file in the library.
But other than support dsf without having to change a default config parameter, is there some other advantage? Thank you again

Yes.

ffmpeg was the original (and only) extractor, but I ended-up implementing taglib as it was faster. I kept ffmpeg around mainly because of DSF support.

Now with taglib 2.0.1 increasing its support for more tag/file formats, the only reason to keep ffmpeg around is that it is better at understanding malformed tags, and also supports some unconventional file formats.

But with multi-valued tags coming soon to Navidrome, taglib will be even more useful than ffmpeg.
