[Bug] Rive-native openGL crashes the android app when using rive renderer [Question] How do I control rive-native RivePlayer playback?

[ssandr1kka]

Guys I see a little issue with rive renderer, but really I rather have a question cuz flutter render works just fine even with feathering...

First of all good job everyone, I have turned into a Rive Addict, your tech's sooo coool and I like my app to rely a lot on it...

Okay so far I've integrated rive-native,
1 - I see that sometimes Android (API 35) + Flutter (3.27.1) is crashing when rive render is set to rive.Factory.rive... This is C++ renderer right?
Here is trace:

E/RiveNative(16823): (12293) EGL_BAD_CONFIG - ../../../../platform/android/rive_native_android.cpp:102
E/libEGL  (16823): call to OpenGL ES API with no current context (logged once per thread)
W/tsy.android.de(16823): 0xebadde09 skipped times: 0
F/libc    (16823): Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x660 in tid 16832 (FinalizerDaemon), pid 16823 (tsy.android.dev)
*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***

pid: 16823, tid: 16832, name: FinalizerDaemon  >>>
and then stack trace of android crash, which will be no help

Something with OpenGL
^ No problem whatsoever when I switch to rive.Factory.flutter

2. I've been looking into example cases, tho I cant seem to find how I can control playback with RivePlayer, located under example/lib, any help please?

@ssandr1kka are you able to reproduce this on multiple devices? Is it only happening on API 35?

Any more information you can give will help us reproduce the issue on our side.

Regarding your other questions:

• Yes, Factory.rive will use the Rive renderer (C++), Factory.flutter will marshal the calls through to Flutter for drawing
• Strange that you're seeing Feathering working with the Flutter renderer, that should not be the case.

@HayesGordon thanks for the response:
Kotlin - 1.9.23
Android - API 35 (Galaxy 21)
Flutter - 3.27.1
More over I see it crashing on my iPhone (11) aswell, I do not think this is an android or iphone specific problem rather it seems to be OpenGL and Flutter V3.27.1, I cannot upgrade project to see whether it happens on other flutter versions.

Here is .riv
https://rive.app/community/files/18524-34832-ninja-tomato/

And the playground.dart

class PlayGround extends ConsumerWidget {
  const PlayGround();

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    return Center(
        child: Container(
      height: 1.sh,
      width: 1.sw,
      color: Utils.isLightMode(context) ? AppColors.white : AppColors.black,
      child: const RivePlayer(
        asset: AppRive.ninjaTomato,
        stateMachineName: 'Main',
        artboardName: 'Main',
      ),
    ));
  }
}

As for inside RivePlayer I have

Future<rive.File?> _loadFile() async {
    final bytes = await rootBundle.load(widget.asset);
    return rive.File.decode(
      bytes.buffer.asUint8List(),
      riveFactory: rive.Factory.rive,
      assetLoader: widget.assetLoader,
    );
  }

Now youd notice that animation has no specific play/pause button, its just linear, the app crashes when I spam the build function (going back and forth the same page before animation is complete)

---

I also have two questions here:

1. Is there a way to pause/play/replay with RivePlayer? If not, how can we do it?
2. Another question is regarding performance... If I like to have 10 different linear animations, is there a way to dynamically serve animation asset to RivePlayer?
   I believe adding 10 assets + initiating a corresponding RivePlayer for each asset and then possibly running then simultaneously may be heavy on CPU thus I am wondering what could be resource friendly approach...

[ssandr1kka]

To answer my own questions:

1. I found it simplest approach to handle it via SM triggers. Also this way we avoid init cpu spikes
2. I have tried loading both multiple rive assets + corresponding RivePlayers and a single .riv with all animations in it and a single RivePlayer... From my tests, the latter is the only way to go about it

[HayesGordon]

@ssandr1kka are you still experiencing the crashes on the Rive Renderer?

[ssandr1kka]

I have not tried rive renderer anymore... I will check and get back

[ssandr1kka]

I do no longer experience the issue with rive_native dev.7

Thanks for confirming!
