Segmentation fault on bigger tv screens

[asnando]

Hi, @ardera!

First of all I'd like to thank for developing this project. I was able to run a project which I've been planning for a long time. And now, using the flutter I could achieve the best perfomance ever!

I've developed my project and got a working version using a forked version of your repo. It's is in the working branch.

It's running fine on my Samsung TV 32 inch, but when I try to run it on a bigger TV screen I get Segmentation fault error without any screen. Full log:

Segmentation fault

Do you have any clue about it?

Thanks in advance!

Glad to hear, good luck with your project! ;)

flutter-pi has received a lot of updates in the past few months, there's a good chance one of these updates fixes your problem (so just pull my master to your working branch). Or is there a reason you use this specific commit of flutter-pi?

Yes, you are 100% right!

In the past I've tried to rebuild flutter-pi with the latest updates from master, but I was getting some erros. I tried to rebuild it now and seems that it was missing the gpiod and libgpiod-dev dependencies. After installation it worked perfectly fine on both TVs. And even better, it gave a better perfomance for the app and turned on some animations (which wasn't working before).

Again, thank you for your help with this project!
