No DLS or MOT-Slides in DABlin_gtk displayed?

[Ben Miller]

Hello Guys,

i've got some issues setting up a simple DAB+-configuration with the ODR-Tools and hope someone can help me.

Here is what i'm doing...

--------------------------------------------------------------------------first---

Generating a "PAD.fifo" with 2 Min Duration while changing/saving the "DLS.txt"-Content with...

odr-padenc -t 'DLS.txt' -d 'MOT_Slides' -v -o 'PAD.fifo'

---------------------------------------------------------------------------next---

Generating a "PROG1.dabp"-File from a VLC-http-Stream for 2 minutes with...

odr-audioenc -v 'http://localhost:8080' -b 88 -l -P 'PAD.fifo' -o 'PROG1.dabp'

---------------------------------------------------------------------------next---

Generating a "1PRO_DAB+.eti"-File (5000 dabframes=2min)  with "1PRO_DAB+.mux"-Configuration-file and...

odr-dabmux '1PRO_DAB+.mux'

result in terminal:

Here is my problem: 

I can hear the audio, but there is no DLS or MOT_Slideshow displayed by DABlin_gtk, just as if there is no PAD available in the ETI-file...and i dont understand why!

(ps.: 

i have shortend the eti.-file to 100 dabframes for the upload. 

i have 4 of the JPGs in the MOT_Slides-Folder.)

thx 4 response.

Hello Ben,

as far as I can see, there are multiple issues here:

- The file "PAD.fifo" seems to be an ordinary file here (as you were able to just attach its content) - but it has to be a FIFO file, which is created by e.g. "mkfifo PAD.fifo"

- You need to set the PAD length for ODR-AudioEnc via the "-p" parameter (ODR-PadEnc uses 58 by default); I will check why there is no warning in case only "-P" is specified for the PAD.

- The signalling for the Slideshow is missing, though some receivers (currently DABlin, too) display the Slideshow without it.
See: http://wiki.opendigitalradio.org/ODR-PadEnc#Service_signalling

Regards,
Stefan

thanks a lot...your quick help, fixed my problems :)

Hi everyone,

The screen was frozen after I typed instructions(sudo odr-padenc -t 'DLS.txt' -d 'MOT_Slides' -v -o 'PAD.fifo') from Ban. Does anyone can help me to fix this issue.

Hi Darren,

Is there indeed a problem here? I don't see any error messages on your screen shot.

 

ODR-Padenc is meant to be used together with ODR-AudioEnc. It will pick up a text from your DLS.txt and slide(s) from your MOT_Slides directory, encode them and send them to your PAD.fifo. I guess that's what happens. You should let your ODR-AudioEnc pick them up from PAD.fifo.

 

P.S: I don't think that sudo is necessary here.

 

Best regards,

Ulrik.
