hpdragon1618 / flutter_gstreamer_player

A GStreamer-powered alternative to Flutter's video_player that support Linux, iOS and Android.

GStreamer Player Plugin

A GStreamer-powered alternative to Flutter's video_player that support Linux, iOS and Android.

Installation

Linux

Follow GStreamer's Install on Linux instuction.

iOS

Follow GStreamer's Install on iOS instuction, step Prerequisites and Download and install GStreamer binaries.

Link GStreamer framework to ios directory for flutter's ios build system.

ln -s /Users/<Your_User_Name>/Library/Developer/GStreamer/iPhone.sdk/GStreamer.framework ios/GStreamer.framework

Android

Follow GStreamer's Install on Android instuction, step Prerequisites and Download and install GStreamer binaries.

In Android, you need to init GStreamer in main activity of your flutter application. In your flutter application, edit MainActivity.kt or MainActivity.java file, depends on your flutter config (This file is usually located at android/app/src/main/<PATH_DEPPEND_ON_YOUR_FLUTTER_APPLICATION>/MainActivity.kt). Import GStreamer module and override onCreate of MainActivity class to init GStreamer, the end result should looks like bellow.

import org.freedesktop.gstreamer.GStreamer

class MainActivity: FlutterActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    GStreamer.init(this);
  }
}

This source code has been tested with GStreamer 1.20.1 prebuild binary

Getting Started

To start using the plugin, copy this code or follow the example project in example

import 'package:flutter/material.dart';

import 'package:flutter/services.dart';
import 'package:flutter_gstreamer_player/flutter_gstreamer_player.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: GstPlayer(
            pipeline:
              '''rtspsrc location=
                  rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4 !
                rtph264depay !
                h264parse !
                decodebin !
                videoconvert !
                video/x-raw,format=RGBA !
                appsink name=sink''',
          ),
        ),
      ),
    );
  }
}

flutter_gstreamer_player's Issues

Unhandled Exception: MissingPluginException on RaspberryPi (flutter-pi)

After compile app as:

$flutter build bundle

for Raspbery Pi under flutter-pi

and run app

I got this error

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method PlayerRegisterTexture on channel flutter_gstreamer_player)
#0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:294:7)

#1 GstPlayerTextureController.initialize (package:flutter_gstreamer_player/flutter_gstreamer_player.dart:18:17)

#2 _GstPlayerState.initializeController (package:flutter_gstreamer_player/flutter_gstreamer_player.dart:60:5)

It's mean plugin doesn't exist after compile app? On desktop works.

Unable to make field private final java.lang.String java.io.File.path accessible: module java.base does not "opens java.io" to unnamed

I'm trying to build the app for android, but i when i do i get:

I'm using Gstreamer android 1.20.1 like in the example and OpenJDK 11.0.18 2023-01-17. I'm on Windows 11, but I also tried on Linux and I can get the Linux desktop app working, but not the android one.

Gstreamer Sink

Odd question and long shot.... I want to create a UI for UxPlay (an airplay receiver) that uses gstreamer. It uses sinks to determinate who is rendering the image. Rightnow, on my buildroot instalation it goes to kmssink.

Is there a way to link this two projects (preferably without rtspsink?), can a widget be used as a sink? That would be ideal. or... do you know any other way to make this work?

Thank you!

Plugin crashing in Linux

Hello, this dependency is amazing! Thanks for that.

I have a single board computer running a USB camera, which I have been trying to stream over WiFi via gstreamer into my laptop's Flutter application, which is running this package.

I have this error whenever I try to pipe in data from the single board computer, and the the entire Flutter App just crashes. The gstreamer command from the single board computer utilises a udpsink to the app.

Gdk-CRITICAL **: 16:00:36.618: gdk_window_get_state: assertion 'GDK_IS_WINDOW (window)' failed
Lost connection to device.

Exited.

The Window opens outside Flutter App

Hi, I have noticed while testing,

The g streamer window opens outside the flutter app . And I can see the error flutter gstreamer failed to read XDG desktop portal settings: GDBus.Error:org.freedesktop.portal.Error.NotFount: Requested setting not found in the console.

How to resolve this error ?

Architecture error on build

Hello!

I'm currently experiencing the following error when trying to build my application:

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':flutter_gstreamer_player:configureNdkBuildDebug[arm64-v8a]'.

[CXX1415] C:\Repos\h264_test\build\flutter_gstreamer_player.cxx\Debug\5w4p5m73\arm64-v8a\android_gradle_build.json debug|arm64-v8a : gstreamer_android-debug-gst-build-arm64-v8a.abi 'gst-build-arm64-v8a' is invalid. Valid values are 'armeabi-v7a, arm64-v8a, x86, x86_64'

I'm building the app on a Windows machine for an Android tablet.
I'm using the recommended (tested) 1.20.1 gstreamer binary.
My NDK version is 21.4.7075529.

Would you know why this is happening? Any information would be appreciated!
