@athoik 
 
I see some changes to dab cmd line
 this may be a fix problem with low snr (DAB band search) RTL SDR ??
 
https://github.com/J...ijk/dab-cmdline


The changes most probably are related only for displaying correctly some special characters, although indeed, few more changes included in the commit, regarding viterbi.

Using attached version now the é, è should work.

There is no change at all
some options seem to have no effect at all ,
The biggest problem is the gain/ amplification during cell tracing.
 
Too bad
, dab cmdline would be good for the plugin.

There's a (good sourced) rumour that ERT will begin test DAB transmissions in the Athens region this week.

I sent Jan (author) email (he may have an idea if he answers)
related to the problem
I personally think that the main problem is very bad SNR during the DAB scan/search 
channel.
And I do not think that the regulation of amplification/gain in this case generally works.
It only works on the frequency of the selected station (if it finds it).

Hi,


I am attaching a new version of dab-sdgradio. I added experimental support for Software based AGC using the code from welle.io.

I can see that gain automatically increases, so most probably it working.

Please report if that makes any change (all options for autogain / manual gain disabled, even if you set them in that test)

There are several approaches, eg create a gstreamer source sink (like fmradioservice) or using binary like serviceapp or standalone servicertlsdr.

But first we need something stable before moving on.

If we are going with servicertlsdr, we are going to write pcm or feed mpg/aac+?

The latter will reduce load (no transcode to pcm).

But pcm or mpg/aac+ requires to deliver PES format, is something easy to do?

Thanks @athoik

 

Unfortunately still does not go,in fact it does not work in all.

the old dab cmd line sometimes works from the first in one second
and sometimes it does not work after two minutes.
What's so strange.

 

Your new dab cmd line error ??

 

no ensemble data found, fatal
RTL_SDR: running set to false.. join thread!
RTL_SDR: running set to false while sleeping... break while!

Dablin-eti is very fast and no problem with ensemble data
but I found out on the net and Git that there was some BUG in it
and because of this we have cracked audio and not because of the processor or  gstreamer
However, the author is no longer active and nobody has fixed that bug.
Something related to ring buffers or the like.What I do not understand but I saw in my logs.
I even read somewhere that an older version did not have that problem.
 
I hope Jan (author dab cmd line ) can help us with the dab cmd line.
 
I'm not sure anymore ???? that we have a problem with SNR ???? because DAB works on another principle
it is a DAB band that uses old analog TV Bands that is 7 Mhz wide
It is divided into 4 DAB abcd bands.

What is really strange is offset.

I need to look if something changes offset, because from offset 0 when ensemble is found, it goes to -24025!!

Offset is not clear to me either
 
I believe the program looks for valid data in a given DAB/DAB+ band
But it does not work for some reason, good and stable.
 
How is it possible RTL-SDR find data once in a second with SNR 17
and many times in two minutes did not find a valid data block ???

Maybe dab-cmdline has some bug in processing.

Also running an IQ raw sample I have the idea that results are not 100 identical.

Hi,

This one will dump raw AAC/Mpeg frames in ouput. Since we are not processing the audio, but gstreamer will do it, this makes program faster.

(test on console after changing -C parameter, it will not work on SDGRadio plugin without changing cmd)

Very good @athoik
Yes, we have significantly less CPU load and much better work
 
my cmd line for plugin
 
cmd = "dab-rtlsdr-sdgradio -C%s -G90 -W30 |  gst-launch-1.0 fdsrc ! queue ! faad !  dvbaudiosink" % DAB_FREQ.get(Decimal(freq), '5A')

Once you find the right ppm, then offset almost drops close to 0 and tune is really fast.
