agora-with-qt's Introduction

Agora With Qt Quick

This opensource project shows how to integrate Agora video SDK with Qt Quick(32bit) and implements video broadcasting

The following features are included in this sample project:

Join / leave channel
Set role as broadcaster or audience
Mute / unmute audio
Change camera
Setup resolution, frame rate and bit rate

Qt Quick

This project use Qt Quick as UI and Agora SDK capture,encode,transfer, decode, render video and audio.

Qt Quick reference Qt Quick website

Agora SDK reference [Agora Document](https://docs.agora.io/cn/Interactive Broadcast/product_live?platform=All Platforms)

Developer Environment Requirements

Win7 or higher/Mac
Qt Creator

Run the sample program

Register your account with Agora.io Registration and create your own test project to get the AppID.Fill in the AppID into source code agorartcengine.cpp

    context.appId = ""; // Specify your APP ID here

Next, download the Agora Video SDK from Agora.io SDK. Unzip the downloaded SDK package and copy the sdk to the "Agora-with-QT" folder in project(the old one may be over written).

Windows： copy folder sdk to the directory where AgoraVideoCall.pro is located in.
Mac：libs/AgoraRtcEngineKit.framework copy to lib folder

Finaly, use Qt Creator to open AgoraVideoCall.pro file, then build and run.

Running Environment

Windows/Mac

agora-with-qt's Issues

在mac book pro上视频的实际显示大小是width/height的2分之1

在mac book pro上视频的实际显示大小是width/height的2分之1。为什么？和分辨的PPI有关吗？怎么解决?

GPU Soft Fault

Can the project run on the Mac M1?

Description:
there are not video screens on the UI window, when we run on the Mac M1
we are sure that the setupLocalVideo and the setupRemoteVideo return 0
and in the app output, it prints:
GPU Soft Fault count: 1

Environment:
OS: Mac OS 12.1
ARCH: arm64
xcode: 12.0
QT Version: 6.2

To Reproduce:

build and run
See output in app console
there are not video screens on the UI window

Expected behavior:
it can show the video screens

多次join、退出、join、退出程序崩溃

建议修改一些glsl代码已适配gles

video_render_opengl.cpp
的片段着色器修改如下

    static const char fragmentShader[] = {
        "#ifdef GL_ES\n"
        "precision mediump float;\n"
        "#else\n"
        "mediump float;\n"
        "#endif\n"
        "uniform sampler2D Ytex;\n"
        "uniform sampler2D Utex,Vtex;\n"
        "varying vec2 vTextureCoord;\n"
        "void main(void) {\n"
        "  float nx,ny,r,g,b,y,u,v;\n"
        "  mediump vec4 txl,ux,vx;"
        "  nx=vTextureCoord[0];\n"
        "  ny=vTextureCoord[1];\n"
        "  y=texture2D(Ytex,vec2(nx,ny)).r;\n"
        "  u=texture2D(Utex,vec2(nx,ny)).r;\n"
        "  v=texture2D(Vtex,vec2(nx,ny)).r;\n"

        //"  y = v;\n"+
        "  y=1.1643*(y-0.0625);\n"
        "  u=u-0.5;\n"
        "  v=v-0.5;\n"

        "  r=y+1.5958*v;\n"
        "  g=y-0.39173*u-0.81290*v;\n"
        "  b=y+2.017*u;\n"
        "  gl_FragColor=vec4(r,g,b,1.0);\n"
        "}\n" };

增加了GL_ES的精度

QQmlComponent: Component is not ready
file:///D:/musdoor/PlugIns/windows/typelist.qml:11:1: plugin cannot be loaded for module "MuseAgora": Cannot load library D:\musdoor\PlugIns\windows\MuseAgora\MuseAgora.dll: 找不到指定的模块。

入口文件代码如下：

#include "museagora_plugin.h"

#include "Cpp/avideowidget.h"
#include "Cpp/agorartcengine.h"
#include "Cpp/museagora.h"
#include "Cpp/testsingleton.h"

#include <qqml.h>
#include <QScopedPointer>

static QObject *agora_engine_singletontype_provider(QQmlEngine *engine, QJSEngine *scriptEngine)
{
    Q_UNUSED(engine)
    Q_UNUSED(scriptEngine)

    return new AgoraRtcEngine();
}

void MuseAgoraPlugin::registerTypes(const char *uri)
{
    // @uri MuseAgora
    qmlRegisterType<AVideoWidget>(uri, 1, 0, "AVideoWidget");

    // 单例模这里会产生问题
    qmlRegisterSingletonType<AgoraRtcEngine>(uri, 1, 0, "AgoraRtcEngine", agora_engine_singletontype_provider);
}

一点点注释点代码最终锁定了出问题的代码

// 注意下面注释掉了m_rtcEngine(createAgoraRtcEngine())和m_rtcEngine->release();
// 这两个只要有一个去掉注释就会引发qmlplugindump上面所说错误，加上注释就能正常生成plugins.qmltypes文件
AgoraRtcEngine::AgoraRtcEngine(QObject *parent) : QObject(parent)
  // ,m_rtcEngine(createAgoraRtcEngine())
  ,m_eventHandler(new AgoraRtcEngineEvent(*this))
{
}

AgoraRtcEngine::~AgoraRtcEngine()
{
    if(m_rtcEngine) {
        // m_rtcEngine->release();
    }
}

以上这个问题只有在windows上会发生，macos下一切正常，这个问题很奇怪为什么？
