WebRTC (Web Real-Time Communication) is a powerful technology that enables real-time communication between web browsers, including video and audio streaming, screen sharing, and file transfer. One of the key features of WebRTC is its ability to capture the screen of a device and share it with other peers in a communication session.
Changing WebRTC Screen Capture Resolution to 1280x720 on Android
When it comes to capturing the screen and sharing it over WebRTC on Android devices, you can use the ScreenCapturerAndroid class, which provides the methods for capturing the screen. By default, the resolution of the captured screen is set to the current device's screen resolution. However, if you want to change the resolution of the captured screen, you can do so by passing the desired width and height values to the startCapture() method of the ScreenCapturerAndroid class.
Setting the Resolution to 1280x720
To change the resolution of the captured screen to 1280x720, you need to call the startCapture() method of the ScreenCapturerAndroid class and pass it the desired width and height values. The method signature of the startCapture() method is as follows:
void startCapture(int width, int height, int displayId)
Here, the width and height parameters represent the desired width and height of the captured screen, respectively, and the displayId parameter represents the ID of the display that you want to capture. To set the resolution to 1280x720, you can pass the following values to the startCapture() method:
capturer.startCapture(1280, 720, Display.DEFAULT_DISPLAY);
Reducing Screen Capture Resolution
When capturing the screen over WebRTC, it's important to consider the bandwidth requirements of the captured video. Higher resolution videos require more bandwidth, which can be a problem if the network connection is slow or congested. Therefore, it may be necessary to reduce the resolution of the captured screen to reduce the bandwidth requirements.
To reduce the resolution of the captured screen, you can simply pass lower values to the startCapture() method. For example, to capture the screen at a resolution of 640x480, you can call the method as follows:
capturer.startCapture(640, 480, Display.DEFAULT_DISPLAY);
In this article, we discussed how to change the screen capture resolution of a WebRTC session on Android devices. By using the ScreenCapturerAndroid class and passing the desired width and height values to the startCapture() method, you can easily set the desired resolution of the captured screen.
