Find the right version of Qt Add-in for your Visual Studio on the Qt website. Download and install it.
Open Visual Studio, in the menu bar, select QT VS Tools > Qt Options > Qt Versions, and add a MSVC compiler.
Copy all the DLL files in SDK/CPlusPlus/Win64/lib (for 64-bit Windows) to the debug/release folder of the project directory.
Note
debug/release is auto-generated after environment configuration in Visual Studio. For 32-bit Windows, copy all the DLL files in SDK/CPlusPlus/Win64/lib to the debug/release folder of the project directory.
2. In the popup page, select RTC Engine, enter the application name, and then click Create.
3. After your application created, you can get your SDKAppID and SDKSecretKey on Basic informaction. SDKAppID and SDKSecretKey is needed for running demo.
Step 2. Download the SDK and demo source code
1. You can download the sample code for 【Windows C++】platform on github.
1.Find and open TRTC-API-Example-C++/TRTC-API-Example-Qt/src/Util/defs.h.
2.Please Modify SDKAppID and SDKSECRETKEY.
SDKAPPID: `0` by default. Set it to the actual `SDKAppID`.
SDKSECRETKEY: left empty by default. Set it to the actual key.
Note
The method for generating UserSig described in this document involves configuring SDKSECRETKEY in the client code. In this method, SDKSECRETKEY may be easily decompiled and reversed, and if your key is disclosed, attackers can steal your Tencent Cloud traffic. Therefore, this method is suitable only for the local execution and debugging of TRTC-API-Example.
The best practice is to integrate the calculation code of UserSig into your server and provide an application-oriented API. When UserSig is needed, your application can send a request to your server for a dynamic UserSig. For more information, see How do I calculate UserSig during production?.
Step 4. Compile and run the demo
Open QTDemo.sln in the TRTC-API-Example-Qt directory with Microsoft Visual Studio (v2019 is recommended), set up the Qt environment (Qt 5.14 is recommended), and run the project.
FAQs
1. The demo is running on two devices, but why can't they display the images of each other?
Make sure that the two devices use different UserID. With TRTC, you cannot use the same UserID on two devices simultaneously unless the SDKAppID is different.
2. What are the restrictions of the firewall?
The SDK uses the UDP protocol for audio/video transmission and therefore cannot be used in office networks that block UDP. If you encounter such a problem, see Firewall Restrictions.
