Using Android SurfaceTexture and Flutter Texture Widget together with Impeller enabled may cause problems. #145077
Description
Steps to reproduce
using the sample code to setup a new flutter project.
and then add this code in AndroidManifest.xml Application section
<meta-data android:name="io.flutter.embedding.android.EnableImpeller" android:value="true" />Expected results
the video should be playing
Actual results
Running these code on Android Api 30+ simulators can crush the app
Running these code on Android Api 31+ simulators also crushes the simulator
Running these code on my Android Api 33+ real device does not crush, but no picture shows up, only the sound is available
I also tested MediaPlayer with TextureView in pure kotlin and the result seems fine
Code sample
Code sample
main.dartimport 'package:flutter/material.dart';
import 'package:flutter/services.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
static const platform =
MethodChannel('com.example.flutter_video_example/channel');
int? _textureId;
@override
void initState() {
super.initState();
platform.setMethodCallHandler((MethodCall call) async {
if (call.method == 'textureReady') {
setState(() {
_textureId = call.arguments;
});
print('textureReady $_textureId');
}
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(title: Text('Video Player Example')),
body: _textureId != null
? AspectRatio(
aspectRatio: 16 / 9,
child: Texture(textureId: _textureId!),
)
: Container(),

);

Hi @xxoo
Does your Android Api 30+ and 31+ simulators support Vulkan? When the crash occurs, can you share the entire error output?
For the issue that the video doesn't render, looks like you hit #141636.

hi @huycozy
This is the log
I didn't see any valuable information in the console when the crush happened.
But now I'm sure it is related to vuklan. Because I just installed Vulkan Hardware Capability Viewer in the simulator. Then the same kind of crush happened.
And when I add this line to AndroidManifest.xml, the crush is gone, but the video doesn't look quite right.

You can open
androidmodule in Android Studio and then openLogcattab to see if there is any error log.I'm unsure about emulator configuration for this. I checked this issue on a physical device
Pixel 7, Android 14which supports Vulkan. There is no crash but the video is not rendered as mentioned above.xxoo commentedon Mar 14, 2024
This is on api 34 simulator, the os crashed
This is on api 30 simulator, the app crashed

Thanks for the update. I don't have such emulators but the error trace may have information to investigate further.

Android surface textures and certain platform views do not yet work with Impeller. The work to fix this can be tracked here: #139702
