Steps to Reproduce

hover run

[nzlov]

#219 Set OpenGL version 4.1.

[pchampio]

does your project works with hover run -b '@gl-3.3'

[pchampio]

@zephylac @nzlov can you check if the https://github.com/go-flutter-desktop/examples/tree/master/texture_tutorial example works on your OS (MacOS, and Windows) using hover run -b '@gl-3.3'

[zephylac]

@Drakirus I'll try ASAP

[nzlov]

@Drakirus My project is working, but https://github.com/go-flutter-desktop/examples/tree/master/texture_tutorial is not, Because dependencies required to run on Windows are simply too complex。

[pchampio]

@nzlov can you check to texture_tutorial with the following go/cmd/options.go file.

package main

import (
	"github.com/go-flutter-desktop/go-flutter"
	"github.com/go-flutter-desktop/plugins/go-texture-example/example_image"
)

var options = []flutter.Option{
	flutter.WindowInitialDimensions(1200, 500),
	// flutter.AddPlugin(&example_video.VideoPlugin{}),
	flutter.AddPlugin(&example_image.ImagePlugin{}),
}

(no additional dependencies required)

Keep using: hover run -b '@gl-3.3' 😉

[pchampio]

[...] gmf._Cfunc_avcodec_send_packet [....] this is related to gmf (the video plugin.)

In the same manner as my above comment, can you please try to run the example without the VideoPlugin?

FIX

[pchampio]

I shouldn't have ask you to run the texture_example.
I've updated the texture_tutorial, can you please retry?

[nzlov]

@Drakirus It's running, but there's no video, no pictures, just white.
