SLS are mixed up with SPI pictures

[andimik]

There is a bug in handling backend. It will show a picture from backend (SPI, EPG service) at the actual service.

If you cannot see the three screenshots, please open it on github.

In the screenshot you see private station Radio 1, but the "SLS" is not their slideshow, but the backend picture from public service PRVI, see following log:

we have now 2 backends running
going to write file /tmp/Qt-DAB-files/357
going to write file /tmp/Qt-DAB-files/e4_9201_32x32_0.png
going to write file /tmp/Qt-DAB-files/e4_9202_32x32_0.png
going to write file /tmp/Qt-DAB-files/e4_9201_112x32_1.png
going to write file /tmp/Qt-DAB-files/e4_9202_112x32_1.png

This will happen when the SLS of the service has not displayed yet AND a picture from backend has been decoded.

After some seconds the correct SLS will be shown:

If I understand it correctly, then a slide, decoded in the EPG service is being displayed (and later overruled as soon the current servide sends its picture?

yes, EPG pictures are shown in a radio program.

It can be solved in a pretty transparent way. It will require minor mods to the backend handling and will therefore impact versions 4, 5, and 6. I probably need the weekend to handle it

Good, the EPG pictures are now NOT showing anymore in the audio service.

But there is still a bug. Qt-DAB won't show the own SLS as it does not update this information. It seems that it crashed internally when received garbage (but this is not related to reception, I just opened the frame dump recording window).

In the attached aac file you see DL+ and SLS

Radio-1-80-a-----Sa--Sept--23-13-11-32-2023.zip

But Qt-DAB did never show it. Please also see "NG BY MYSELF" which was part of the garbage frame. See other (still not solved issue) https://github.com/JvanKatwijk/qt-dab/issues/280
