Cocos v3.15.1 effects don't work (Android 5.1.1)

cocos2d-x C++
#1

Hi,

I am using LensEffect in my project. I just started testing and unfortunately effects from cocos v3.15.1 don’t work on Samsung Grand Prime with Android 5.1.

Here is a crash log from Android Studio where I run “Effects Basic” from cpp-tests.

(It worked perfectly with cocos v3.12… :/).

SIGSEGV (signal SIGSEGV: invalid address (fault address: 0x1b6a33c))

Could you point me somewhere?

I just checked cpp-tests with cocos v3.17 and the result is the same, Effects crash on Grand Prime with Android 5.1.1.

#3

Hi. We are using 3.15 and all effects not work in cpp-test for android 5.
Replace CCTextureCache.cpp in 3.15 with the same one in 3.17 stable version.

#4

@amin13a Thanks for reply. Do you say that replacing CCTextureCache.cpp with the one from v3.15 solves the issue?

I have checked v3.17 cpp-tests (clean build) on the same device and I got a crash when I tried to run effects.

#5

Yes. for me it works. cocos v3.17 cpp-tests also works.
I don’t know why v3.17 crash when you run effects.

#6

Did your test run on a Samsung Grand Prime with Android 5.1? That specific phone graphics chip seems to have some buggy graphics driver, because if you search online you’ll see quite a lot of references to it from other game engines too.

#7

Unfortunately changing CCTextureCache to the one from 3.17 doesn’t help.

The thing is that it worked fine in 3.12…

#8

Then your problem solved?

#9

No, it is not solved :wink: I have already migrated project to 3.15.1 and I don’t want to move back to 3.12. For now I just disabled effect on Android :frowning:

I think that finally I will disable effect for this specific device (if it will be possible) or I will write my own shader to do the similar effect.

#10

Problem is still not solved :confused: As a workaround I wrote custom shader to achieve similar effect.
