[PROBLEM] DSD1024 support

[TheOldPresbyope]

And then you said "Looks like the same file as the OP."

Rats, I should have looked past the filename to the size, duration, etc. So not necessarily an independent test after all.

I don't know of a tool which can vaildate DFF/DSF file formats (a modified IFF). 

Running

mediainfo --details=1 <filename>

gets me encouraging output which looks similar to the output for lower res DSD files.

Let's assume the file is valid.

Here's a snippet from verbose MPD log

Code:

Jul 11 09:43 : client: [12] opened from 127.0.0.1:43350
Jul 11 09:43 : client: [12] process command "play"

Compare this to a similar snippet when playing a DSD512 track obtained from same website 

Code:

Jul 11 09:48 : client: [10] process command "play"
Jul 11 09:48 : playlist: play 0:"USB/RALLY8GB/Music/DSD/o5-Babel (DSD512).dff"
Jul 11 09:48 : client: [10] command returned 0
Jul 11 09:48 : client: [10] process command "close"
Jul 11 09:48 : client: [10] command returned 4
Jul 11 09:48 : client: [10] closed
Jul 11 09:48 : decoder_thread: probing plugin dsdiff
Jul 11 09:48 : decoder: audio_format=dsd512:2, seekable=true
Jul 11 09:48 : alsa_output: opened _audioout type=COPY
Jul 11 09:48 : alsa_output: buffer: size=178..131072 time=252..185760
Jul 11 09:48 : alsa_output: period: size=89..65536 time=126..92880
Jul 11 09:48 : alsa_output: default period_time = buffer_time/4 = 185759/4 = 46439
Jul 11 09:48 : alsa_output: format=DSD_U32_BE (Direct Stream Digital, 4-byte (x32), big endian, oldest bits in MSB)
Jul 11 09:48 : alsa_output: buffer_size=131072 period_size=32768
Jul 11 09:48 : output: opened "ALSA Default" (alsa) audio_format=dsd512:2

In particular, note the difference between

Code:

decoder: audio_format=6144000:dsd:2, seekable=true

and

Code:

decoder: audio_format=dsd512:2, seekable=true
