Post by F1NST-Bernard » Sat Oct 21, 2017 2:32 pm

Hi everyone,

In the last version I noted that call could be included in the MPG2 image. In page 2 a special button is implemented to validate this function. This could also be controlled in rpidatvconfig .txt with value on for captionon. Unfortunately, the call does not appear on the screen. I checked that the correct font was in place and for a test I changed the color from white to yellow which could be more lisible but nothing.

Any help is welcome. Thanks

Not sure its a good idea to edit the config files directly. Here is what mine looks like so you can compare. There is nowhere to set a font or change the caption colour.

Merci Dimitri, well noted the call position on the screen. I pursue my investigations. Version 201710081

For the color, it is not in the config file, it is in the a.sh script in the MPG2Cam command . We can modify other things, font and dimensions for example.

Shall keep you informed

Bernard

One thing to check is that your rpidatvconfig.txt file does not have any space characters in it (even at the end of the lines). This is a problem that I hope to solve soon.

You could try doing a factory reset (Advanced System Setup Menu, option 9 on the console)

If that doesn't work, try doing a forced upgrade by saying that you want to upgrade anyway, even though you already have the latest version.

What symbol rate do you have set?

Hi Dave,

Thanks your help.
No problem on my rpidatvconfig.txt.

I'm with SR 1500 but it is same with 333.

I will try the factory reset.

Shall revert

Dave,

Factory reset and update does not make any difference. No caption. It is not important but helpful for the correspondent.

No more problem.

In fact, caption does not appear on my screen but it is perfectly visible on the air. So, resolved.
I was awaiting the last Minitioune soft to control my signal and on receipt I could check that it was perfect.As stated only on MPEG2 .

Thanks again

Thanks for letting us know.

Yes, the caption is only visible on-air, as it is added during the (MPEG-2) video coding using ffmpeg, after the image has been displayed on the touchscreen.
