IRtcEngine rtc = IRtcEngine.QueryEngine() Д®xternalVideoFrame externalVideoFrame = new ExternalVideoFrame() Checks whether the IRtcEngine instance exists. Int size = Marshal.SizeOf(bytes) * bytes.Length Gives enough space for the bytes array. Gets the raw texture data and apply it to an array of bytes.Д«yte bytes = mTexture.GetRawTextureData() Applies the pixels read from the rectangle to the texture. Reads the pixels of the rectangle you create. Creates a texture of the rectangle you create. MRect = new Rect(0, 0, Screen.width, Screen.height) Creates a rectangular region of the screen. MRtcEngine.JoinChannel(channelName, null, 0) MRtcEngine.SetExternalVideoSource(true, false) MRtcEngine.SetLogFilter(LOG_FILTER.DEBUG | LOG_FILTER.INFO | LOG_FILTER.WARNING | LOG_FILTER.ERROR | LOG_FILTER.CRITICAL)

MRtcEngine = IRtcEngine.GetEngine(appId)

Refer to the following code to share the screen in your project. The following diagram shows the API call sequence for sharing the screen via external video source.

int a = rtc.PushVideoFrame(externalVideoFrame) MTexture = new Texture2D((int)mRect.width, (int)mRect.height, TextureFormat.RGBA32, false) Д¬all PushVideoFrame to send the video source to the SDK and to implement screen sharing. mRect = new Rect(0, 0, Screen.width, Screen.height) mRtcEngine.SetExternalVideoSource(true, false) Дefine the Texture2D, and use Texture2D to read screen pixels as an external video source. Specify the external video source by calling SetExternalVideoSource before JoinChannelByKey. Refer to the following steps to share the screen via external video source in your project: The differences of the two approaches for screen sharing are as follows:Д®ntire desktop or app region/window running on the platform See Start a Video Call or Start Interactive Video Streaming for details. The following screen shots give you a glimpse of the two sample projects when implementing screen sharing.Д«efore sharing the screen, ensure that you have implemented the basic real-time communication functions in your project. Desktop screen sharing: Agora Unity Video SDK Demos.Agora also provides open-source sample projects on GitHub that implement screen sharing on Unity in the two ways: The Agora Unity SDK provides two ways of screen sharing, namely app screen sharing and desktop screen sharing. In an online class, the teacher can share the slides or notes with students.In a video conference, the speaker can share an image of a local file, web page, or presentation with other users in the channel.Screen sharing is applied in the following scenarios: During a video call or interactive streaming, sharing the screen enhances communication by displaying the speaker's screen on the display of other speakers or audience members in the channel.
