RAI DAB+ feed from 5 West

[EnoSat]

Have you tried to process Multistream 11 from 11013V which should contain DAB in the enigma2 box?

Yes, not with Enigma2 myself (although that would be perfectly possible using the channel created in the lamedb code you have added above), but you can decode it using eti-tools GitHub - piratfm/eti-tools: ETI conversion software -

curl -s http://192.168.0.224:9981/play/ticket/stream/mux/4f60a849e857f04c944d36b821f997aa?pids=1000 | ts2na -p 1000 -s 0 | na2ni | ni2out --list

I'm using TVHeadend, but you can replace the URL after curl -s with the URL of your Enigma2 channel and it will work exactly the same.

You get this -

You can play it using dablin-gtk in Linux. I'm not sure if something similar exists for Windows.

You can even modulate it using a HackRF if you like, using odr-dabmod

Both of those replace ni2out --list in the command line.

Is there any receiver able to process these streams? My linux skill is very poor, so I need such finished product or any Windows software that can be used with my TBS5925 PC card. Thank you.

A complete dummies question!

How do I get the DAB service reference on an Enigma2 box? i..e EnoSat's "1:0:1:1:FA:C8:DDEAB05:0:0:0:"

On my Octagon SF8008 with OpenATV 6.4, I can lock 11013V Stream 11, but scan gets "0 channels found".

I seem to remember that scan returned data channels back in the days of Enigma1.

I am very comfortable with Linux command line and have installed the ETI utilities and dablin on my Gentoo desktop.

 

[EnoSat]

e2 creates a line after scanning in lamedb

0ddeab05:00fa:00c8
    s 11013000:35295000:1:2:-50:2:0:1:2:0:2:11:131070:1
/

next step, manual create virtual DATA channel for DAB channel in lamedb

[Dggrr]

Many thanks - worked perfectly

curl -s http://192.168.1.11:8001/1:0:1:1:FA:C8:DDEAB05:0:0:0: | ts2na -p 1000 -s 0 | na2ni | dablin_gtk 2>/dev/null

The 2>/dev/null redirect gets rid of annoying constant "[X-PAD len]" error messages.

Now to see if I can do the same with the other DAB services listed in the eti-tools README.

It would be nice to automate the tuner lock, as well. Actually tuner lock is not a problem if I something else is not already locking my single LNB for 5W

Hi Everybody,

The problem with E2 is that only the MPEG2 radios plays correctly.
RAI and many other stations are broadcasting now using AAC and the troubles begins...
AAC stations are tuned and streamed correctly but they play like they're broadcasting from a cavern 100 meters deep.
I forgot to mention: to decode dab feeds you need a SatDreamGr image, is the only one with eti-tools integrated.
In other forum there's a great tutorial by MCelliotG (in greek but thanks to google translator i made it work)

I think eti-tools built in the image needs an update but, of course, i don't have the skills...

Ahh very useful!

I've not tried it myself with the Enigma2 in-built eti-tools in SatDreamGr, but it sounds like it's because of the AAC decoder in Enigma2 not having DAB+ support.

DAB+ encoding uses a slightly different encoding method with AAC where (I think) the number of audio samples per frame in within the audio stream are different to usual (it's referred to as AAC960). This requires the AAC decoder in the device/computer to take this into account, otherwise the audio plays as if it's been slowed down - with the 100-metre-deep cavern effect you are describing.

The AAC decoder used in Dablin in Linux takes this into account so they play correctly, maybe someone can achieve this in Enigma as well!

 

[cirio70]

Excellent analysis!!!!
You've made the picture brighter, Thanks!

 

[tvroman2]

So is it a question of updating the decoder used in enigma to handle DAB+ or is there another issue as well stopping it working on AAC960??

It would just be a question of updating the audio decoder, but the issue would be how easy this is to achieve within Enigma2. I don't know enough about it to tell you what that would involve.

It may be that it's entirely handled by the hardware of the receiver, like the video is.

 

[tvroman2]

Yes, I was afraid that it might be a limitation of the hardware. I am not at home at present, but I think it bears researching anyway. Even if it is hardware, modern machines are powerful enough to do it in software I expect.

 

[ozumo]

It's been mentioned that Kodi can be used on an SF8008 to view 4:2:2, which I assume is using a software decoder. Might be worth trying Kodi to see if it can play back recorded AAC960 files.

 

[tvroman2]

Unfortunately I am travelling until early April but I can certainly test that out with Kodi on an SF8008 when I return unless somebody else cares to try in the meantime.

 

[Dggrr]

On reading the dablin documentation .....

"To anyhow process affected X-PADs, a loose mode can be enabled by using the -L parameter."

So instead of "..... dablin_gtk 2>/dev/null", "dablin_gtk -L" is much cleaner and the Rai slideshow also begins to work

e.g.

curl -s http://192.168.1.11:8001/1:0:1:1:FA:C8:DDEAB05:0:0:0: | ts2na -p 1000 -s 0 | na2ni | dablin_gtk -L

I recorded a minute of Virgin Anthems and in my PC it plays with both VLC and MPC
Here's mediaInfo result:

Using internal E2 Mplayer the file plays weird but at least we know that the stream is decoded right.
Tomorrow i'll try to install kodi and see what happens
EDIT: Installed kodi-> File plays OK!
So it's "only" a codec problem

 

[cirio70]

OMG!
It was easy as ABC
Since as i said i'm not a linux expert but a noob, my approach is trial and error.
So i studied and the codec responsible for the sound is libavcodec58
I took the libavcodec58 from my zgemma (the chipset is the same as ocatagon) and i replaced the one in my octagon and BOOOM!
AAC channels plays like a charm
It turns out SatDreamGR is shipped with version 58.54.100, OpenAtv in my Zgemma have the version 58.134.100

Nice work! Sounds like it should be an easy fix for them to replicate in SatDreamGr for future releases in that case too.
