PS. I used ffmpeg to "mux" raw pcm into wav, because VLC cannot understand raw pcm, produced from dab-rtlsdr-sdgradio-pcm.

 

 

But VLC is playing slow pitch sound.....

ffmpeg -f s16le -channels 2 -r 48000 -i pipe:0 -f wav pipe:1

It's wrong.

 

 

It has to be :

ffmpeg -f s16le -channels 2 -ar 48000 -i pipe:0 -f wav pipe:1

Now sound is OK.

I didn't know it, but looking at help (ffmpeh -h) I found it.

Video options:
...............
-r rate             set frame rate (Hz value, fraction or abbreviation)
...............
                                                                                                       
Audio options:
..............
-ar rate            set audio sampling rate (in Hz)

Anyway after some minutes (5) playing, audio stops, using as a favourite on box, sf8008.

#SERVICE http://localhost:5237/dab/.....

You have to kill both dab-rtlsdr-sdg......  and ffmpeg processes to get audio again.

When audio stops, on dastreamer manualstart log it doesn't appear anything:

I notice that it stops too.

No idea why that happens, the SDGRadio uses same binary as well, but feeds the dvbaudiosink directly, no issues there.

The idea is simple, use a binary, produce stream, feed enigma2.

Maybe it's the ffmpeg, but we need to mux into wav.

....and that binary works perfectly inside sdgradio.....so it has to be ffmpeg's fault....

I've read in several places that when ffmpeg stops converting after a few minutes is because buffer is overflowed.

Then it has to include option -re before input file

I've tried it, but then I get 2 seconds of good audio, and after that you have to stop it otherwise your ears will be damaged.........

I took another approach.
 
I manage to compile the welle-cli (https://github.com/AlbrechtL/welle.io).
 
There is an option to start a streaming server using welle-cli.
 
root@osmio4kplus:~# cd /usr/share/welle-io/html && welle-cli -c 12C -w 5238 -g -1

Then from web UI you can play the radio you like (assuming that you are using your computer), watch spectrum, constellation etc.

Using the url http://localhost:5238/mp3/4098 you can play radio on the receiver as well.


I think welle-cli needs a small change in order to allow frequency change from GET.

https://github.com/A...erface.cpp#L477

Something like http://localhost:5238/mp3/12C/4098 that will retune and setup channel, so no access to web would required to switch to another frequency.

I don't understand exactly why you say that welle-cli needs a small change in order to allow frequency change from GET.

When you launch welle-cli binary from cmd, you can pass frequency and program

 

http://localhost:5238/mp3/12C/4098

 

elif tool == "mp3":

_, channel, program = parameters

cmd = "welle-cli -c %s -p %s " % (channel, program)

 

 

Doesn't it work ?

 

Is it (welle-cli) on any SDG feed ?

Welle CLI already offers a streaming server. Also it doesn't offer a way to stream wav/pcm directly on output (Or I didn't find it yet).

 

So in order this to work from bouquets, it should have the option to change the current frequency.

 

Otherwise you need to use the web UI to switch to another channel.

 

So i made a patch to handle the channel change, also to send the index.html/index.js from the installed path.

Webserver works, and I can hear them using red play button from there.

 

But I don't know if now VLC should work , because it stops just after starting, no time to hear anything... and I have no audio on enigma box (sf8008) too.

PS. Try also the URL with decimal number.

Eg 0xEFF9 is 61433.

Or hex to lower case.

Althought it works, frequency change needs finetuning......

 

Zapping from one frequency to another isn't fine.

I've added one favourite program more to make tests between frequencies.

#NAME DAB
#SERVICE http://localhost:5238/mp3/8A/0xeff9
#SERVICE http://localhost:5238/mp3/8A/0xeff6
#SERVICE http://localhost:5238/mp3/8A/0xefed
#SERVICE http://localhost:5238/mp3/11B/0xeff2
#SERVICE http://localhost:5238/mp3/11B/0xeff3

As you see, 1 to 3 are on block 8A, and 4 and 5 are on 11B.

 

 

If I'm listening to any 8A program and I zap to another 8A program, it zaps instantly and no problem at all...

 

But If I'm on 8A and I zap to a 11B program (4), it doesn't work.  I have to zap again to the other one on 11B (5) and then it works, and after that I can zap continously from 4 to 5 ,,,,,

 

Same applies back to 8A.

If I'm in 11B and I want to zap to a programm on 8A, I have to zap twice, and after that, no problem at all among all on 8A.

 

Here the full log:
