flutter-pi: VideoPlayer is not working (Gstreamer).

First of all, thanks for creating flutter-pi, this is such a great project!

I am having some issues after trying to run an application with the video_player package, exactly the one recommended in the example part of Readme (https://pub.dev/packages/video_player#example). Please fin the details below:

-flutter_assets bundle generated in Ubuntu 18.04 machine (all process) -video_player: 2.5.1 (and with some older versions too like 2.4.5) -Device: STM32MP157F-EV1 (32 bits MPU) -Flutter: 3.3.10 -flutter-pi: Latest version available in Master -engine-binaries: Latest version available in your repo.

Command: ./flutter-pi -r 270 --release /usr/local/flutter331/flutter_assets/

Output:

[locales] Warning: The system has no configured locale. The default "C" locale may or may not be supported by the app.

[compositor] GPU does not support reflecting the screen in Y-direction.
  This is required for rendering into hardware overlay planes though.
  Any UI that is drawn in overlay planes will look upside down.
[compositor] GPU does not supported the desired HW plane order.
  Some UI layers may be invisible.

I have also tried VideoPlayerController.asset instead of .network, but issue persists.

In addition, during flutter-pi building, after doing make command, different errors were displayed: [ 4%] Building C object CMakeFiles/flutter-pi.dir/src/flutter-pi.c.o In file included from /usr/local/flutter331/flutter-pi/src/flutter-pi.c:47: /usr/local/flutter331/flutter-pi/include/flutter-pi.h:57:2: error: expected specifier-qualifier-list before 'FlutterEngineResult' 57 | FlutterEngineResult (*FlutterEngineCreateAOTData)(const FlutterEngineAOTDataSource* source, FlutterEngineAOTData* data_out); | ^~~~~~~~~~~~~~~~~~~ In file included from /usr/local/flutter331/flutter-pi/src/flutter-pi.c:47: /usr/local/flutter331/flutter-pi/include/flutter-pi.h:160:8: error: unknown type name 'FlutterTransformation' 160 | const FlutterTransformation t, | ^~~~~~~~~~~~~~~~~~~~~ /usr/local/flutter331/flutter-pi/include/flutter-pi.h: In function 'apply_flutter_transformation': /usr/local/flutter331/flutter-pi/include/flutter-pi.h:168:10: error: request for member 'scaleX' in something not a structure or union 168 | *px = t.scaleX*x + t.skewX*y + t.transX;

I could solve them by setting FLUTTER_EMBEDDER_HEADER (in the CMake file) to the flutter_embedder.h provided in your engine-binaries repo.

Thanks in advance!
