[FR] DSD Support

[parkmino]

Could it be possible to support DSD file format?

Hey @parkmino - I did some searching on this it seems like Linux systems are based in PCM (pulse-code-modulation). To get a DSD format to play directly on Linux you need special hardware (I think..?)

You could convert the DSD to PCM and then stream it via Gerbera. I haven't tried using dsf2flac but perhaps you could use Gerbera Transcoding to output the file in an acceptable UPNP format?

Yes, DSD capable DAC is needed which supports native DSD or DoP(DSD over PCM).
AFAIK, AssetUPnP, DSD patched MiniDLNA, MinimServer, Logitech Media Server, JRiver MC for Linux supports DSD at the moment.
It would be great for me to play DSD files with Gerbera+MPD+Upmpdcli combination.
Please refer to the following link for the MiniDLNA DSD patch for your reference.

DSD files are visible not in Audio but in PC Directory.
I found out an workaround to play DSD in upmpdcli.conf
checkcontentformat = 0
Now, dff files in PC Directory play!
However adding DSD file formats to Gerbera would be great though.

DSD is possible in database too. I have been using this since version 1.1 to play DSD files (*.dsf oder *.dff). Only integrated covert art is not (yet) supported.
In the config.xml file, only the following lines must be added:
In the mappings node:

        <map from="dsf" to="audio/x-dsd"/>
        <map from="dff" to="audio/x-dsd"/>

And in the mimetype-contenttype node:
<treat mimetype="audio/x-dsd" as="dsd"/>

Thats all. So i can play native DSD with my Sony AVR (STR-DN1070).

@dieneuser
Thanks for your information, it works on my side as well.
Registering DSD file types to config.xml as default should close this issue then.

@parkmino - Great news on the success. I am familiar with the configuration defaults, so will post the defaults for DSD types soon.
