SACD/DSDIFF playback in XBMC

HeresJohnny · 2011-07-26 21:22

A request with a sidewise glance at the upcoming AE engine:

Would love to see SACD ISO and DSDIFF playback in XBMC. Code can be found here:

http://sacddecoder.sourceforge.net

Thanks for considering it!

I would love to have it too!
I'm trying to get around it by adding an external player (foobar2000) but because the tracks are in cuesheet (cue/dff) the album will then played multiple times if I select the first track... Frown

This would be amazing, but I understand that there is no much demand.

Hi there. About a two weeks ago I e-mailed the creator (Maxim Anisiutkin) of the foo_sacd.dll code asking if I could port it to XBMC as part of the AE sub-system. I have not received an answer yet. I have a very strong interest in this as well.

DSD, especially DST multi-channel playback is very CPU-intensive, and even on a decent rig it can stutter with other processes running, so I have my doubts as to whether visualizations can still run. But to have the code ported/adapted would be great as horsepower keeps increasing.

He has released his code, so it's open-source, but it's still also copyrighted material. For that reason I wanted his permission to proceed.

I'll try again to contact him - I have around 60 SACD's ripped to ISO, and prefer not to convert them all to FLAC.

With AE we can get 24-bit audio, so conversion to FLAC becomes feasible, but if I can get permission to port the code all the better.

Both are already released under an open source license? sacddecoder is LGPL and sacd-ripper is GPL v2

Yep. Whatcha think? I've been through the code at a glance and with AE it's gonna sound pretty sweet at 24/88.2 or 24/176.4. It transcodes to PCM so it's an easy enough mesh. In Foobar they sound outstanding. I can pass floats straight to AE.

There'll be some work probing the .ISO file to determine that it's an SACD as opposed to a DVD image, the rest is adhering to the XBMC decoder API, but the gist of it is already done.

I figured with AE it's worth doing. I e-mailed him again today, but I guess it's cool license-wise.

EDIT: One other bit of fun will be integrating the "inside view" of the .iso. Most people keep the full iso as opposed to seperating out the various tracks. The foobar plugin looks inside the iso and returns the track list, so this will take some work to integrate into XBMC's list functions.

Hi Damian,

Yes, sure. Use the code at your discretion. [/i]

Hi there,

Wonderful job on the SACD decoder. I help out a little on a free, open-source media player called XBMC, available here: http://xbmc.org/

I was thinking that SACD playback would be a great addition to this multi-codec, multi-platform player.

I wondered if you would allow me to use some of your code to make this happen!

Cheers,

Damian

you know Im no dev, but maybe it's worth looking into (if possible) offloading the decoding to cuda or the alternatives ?

**DanielaE** · 2012-02-17 12:07

GPU offloading is one possible solution to the decoding problem, but it might turn out a better idea to take advantage of modern CPU's SIMD and vectorize the filter code instead. It depends on the algorithmic structure - more FIR or more IIR like - which hardware is more up to the task.
