Correct. In theory DTS-MA HD is a software problem. Once ffmpeg supports it, then you will get lossless DTS-MA HD on Pi 2 but there is no guarantee that will happen anytime soon.

Platforms that support lossless DTS-MA HD are pretty rare. Probably a Chromebox is the best option.

Well basically any x86 machine with HDMI out.

Apart from nVidia, AMD and Intel based x86 boxes made in the last 4 years or so - with a couple of exceptions? (The Chromebox is just an x86 Celeron box really)

That makes the choice somewhat easier Smile

Thanks!!

I'm having issues playing AAC 5.1 files from the rpi2.
Before that I had a atom media center and the sounds was ok.

Is there a settings that needs to be disabled/enabled? It seems that only specific channels getted passed trough because I can hear background noise but no voices etc.

Sounds like you have "number of channels" set too high for your audio equipment.
Try setting to 2.

How are you connecting your Pi 2 to your TV or Amp.

How many audio channels does your TV or Amp support ?

Are you transcoding to Dolby Digital or decoding?

RPI2 -> Samsung LED TV (UF8500) -> SONOS PLAYBAR

I'm using the same Kodi build on a Atom mediaplayer (Xtreamer Ultra) with the same settings (stock), without any issues.

TV supports DTS/AC3/5.1 etc..
I'm using passthrough with DTS/AC3 capable.

Is it possible to decode/encode AAC 5.1 to AC3 5.1? Because all DD5.1 and DTS movies/episodes are playing fine.

Yes. Make sure "number of channels" is set to 2, and enable AC3 passthrough and enable "Dolby Digital transocoding"

Hi all new here.

I've had a pi1 rev b 512ram model for a while using it on xbmc/kodi using raspbmc

thinking of getting a pi2

my question is would i see a noticable difference in picture quality while streaming live tv as on a 46" tv it's not the best quality

also would using openElec be better than using raspbmc

cheers
john

Having owned both, a fully Overclocked RPi1 and now a RPi2 - the answer is the picture quality is exactly the same.
Deinterlacing is the same on both for Live TV as well.

The GPU/VPU was not upgraded, just the CPU cores and memory I understand.

Kodi GUI is a wee bit faster, and you can now do more than one thing in the background such as running a TvHeadend server and the Kodi client on the one Pi 2.

OpenElec and RaspBMC are speedwise - neck and neck.
People generally migrate to Openelec initially as it is a bit less confusing to setup with fewer options to baffle the Newb.

Thanks wrxtasy, thats exactly the answer i wanted even though i was hoping it would be an improvement but understand why it wouldn't be.

cheers

edited to add, do you have a ASUS Chromebox, as i guess a machine like that would give me a better picture quality...?

nickr · 2015-03-10, 21:09

Why do you say that?

noggin · 2015-03-10, 23:55

Chromebox will do a better deinterlace of native interlaced content (though the MMAL stuff in the Pi / Pi 2 is not terrible and is x2), and may do a better SD to HD upscale than the Pi/Pi2 (but again the Pi does a pretty good job), but for 1080p output at 1080p there probably isn't much of a quality difference.

Garbage in, garbage out. Quality in, quality out.
