Audio decoding in DSD format is not supported

[pth2000]

I am using QT to develop a music player. I found that when I tried using LavFilters it could decode formats like FLAC, WAV, etc., but I got errors when I tried DFF or DSF formats.

For example:
DirectShowPlayerService: : doRender: Unknown error 0 x80040266.

Is there any way to solve this problem? Thank you very much!

LAV Audio supports decoding DSD, but the output is a unusual high sample rate, and you'll need a audio renderer that is capable to accept it - most are not.

If you use MPC-HC player, then both SaneAR and MPC Audio Renderer support resampling such high sample rates.
Options > playback > Output > Audio Renderer

The default DirectSound renderer that is used by your application does not support it.
