Introduction

rtc-detect is used to detect whether the current environment is working smoothly in WebRTC application built by TRTC SDK.

Install

npm install rtc-detect

How to use

import RTCDetect from 'rtc-detect';
// init
const detect = new RTCDetect();
// get detect result
const result = await detect.getReportAsync();
console.log('result is: ' + result);

API

(async) isTRTCSupported()

This API is used to check whether the current environment supports TRTC.

const detect = new RTCDetect();
const data = await detect.isTRTCSupported();

if (data.result) {
  console.log('current browser supports TRTC.')
} else {
  console.log(`current browser does not support TRTC, reason: ${data.reason}.`)
}

getSystem()

This API is used to get the current system environment parameters.

Item	Type	Description
UA	string	user agent
OS	string	system
browser	object	browser infomation: { name, version }
displayResolution	object	resulution: { width, height }
getHardwareConcurrency	number	current device CPU core count
GPU	string	GPU info

const detect = new RTCDetect();
const result = detect.getSystem();

getAPISupported()

This API is used to get the API support of the current environment.

Item	Type	Description
isUserMediaSupported	boolean	whether to support getting user media from media device
isWebRTCSupported	boolean	whether to support WebRTC
isWebSocketSupported	boolean	whether to support WebSocket
isWebAudioSupported	boolean	whether to support WebAudio
isScreenCaptureAPISupported	boolean	whether to support getting media steam from screen
isCanvasCapturingSupported	boolean	whether to support getting media stream from canvas element
isVideoCapturingSupported	boolean	whether to support getting media stream from video element
isRTPSenderReplaceTracksSupported	boolean	whether to support not renegotiating with peerConnection when replacing track
isApplyConstraintsSupported	boolean	whether to support changing the resolution of the camera without re-calling getUserMedia

const detect = new RTCDetect();
const result = detect.getAPISupported();

(async) getDevicesAsync()

This API is used to get the available devices in the current environment.

Item	Type	Description
hasWebCamPermissions	boolean	Whether the user camera data can be obtained
hasMicrophonePermission	boolean	Whether the user mic data can be obtained
cameras	array	A list of the user's camera devices, including information on the resolution of supported video streams, maximum aspect and maximum frame rate (maximum frame rate is not supported by some browsers)
microphones	array	A list of user mics
speakers	array	A list of user speakers

CameraItem

Item	Type	Description
deviceId	string	Device ID, which is usually unique and can be used to capture identifying devices
groupId	string	Group identifier, two devices have the same group identifier if they belong to the same physical device
kind	string	Camera device type: 'videoinput'
label	string	Label describing this device
resolution	object	Information about the camera's supported resolutions, maximum width and height, and maximum frame rate, eg: {maxWidth: 1280, maxHeight: 720, maxFrameRate: 30}

DeviceItem

Item	Type	Description
deviceId	string	Device ID, which is usually unique and can be used to capture identifying devices
groupId	string	Group identifier, two devices have the same group identifier if they belong to the same physical device
kind	string	Physical device type, eg: 'audioinput', 'audiooutput'
label	string	Label describing this device

const detect = new RTCDetect();
const result = await detect.getDevicesAsync();

(async) getCodecAsync()

This API is used to get the codec support of the current environment.

Item	Type	Description
isH264EncodeSupported	boolean	whether to support h264 uplink
isH264DecodeSupported	boolean	whether to support h264 downlink
isVp8EncodeSupported	boolean	whether to support vp8 uplink
isVp8DecodeSupported	boolean	whether to support vp8 downlink
isVp9EncodeSupported	boolean	whether to support vp9 uplink
isVp9DecodeSupported	boolean	whether to support vp9 downlink
isH265EncodeSupported	boolean	whether to support h265 uplink
isH265DecodeSupported	boolean	whether to support h265 downlink
isAV1EncodeSupported	boolean	whether to support AV1 uplink
isAV1DecodeSupported	boolean	whether to support AV1 downlink

const detect = new RTCDetect();
const result = await detect.getCodecAsync();

(async) getReportAsync()

This API is used to get the detection report of the current environment.

Item	Type	Description
system	object	same as getSystem() result
APISupported	object	same as getAPISupported() result
codecsSupported	object	same as getCodecAsync() result
devices	object	same as getDevicesAsync() result

const detect = new RTCDetect();
const result = await detect.getReportAsync();

(async) isHardWareAccelerationEnabled()

This API is used to check whether hardware acceleration is enabled on the Chrome browser.

Note: the implementation of this API depends on the native WebRTC API. We recommend you call this API for check after calling isTRTCSupported. The check can take up to 30 seconds as tested below:

• If hardware acceleration is enabled, this API will take about 2 seconds on Windows and 10 seconds on macOS.
• If hardware acceleration is disabled, this API will take about 30 seconds on both Windows and macOS.

const detect = new RTCDetect();
const data = await detect.isTRTCSupported();

if (data.result) {
  const result = await detect.isHardWareAccelerationEnabled();
  console.log(`is hardware acceleration enabled: ${result}`);
} else {
  console.log(`hardware acceleration is disabled`)
}
