实时视频通话功能
|

TRTC APP 实时视频通话功能
|
||
本文件展示如何集成实时视频通话功能
|
||
1、切换摄像头 API:[[_trtcCloud getDeviceManager] switchCamera:_isFrontCamera];
|
||
2、打开关闭摄像头 API: [self.trtcCloud startLocalPreview:_isFrontCamera view:_localVideoView];
|
||
[self.trtcCloud stopLocalPreview];
|
||
3、切换听筒与扬声器 API：[[_trtcCloud getDeviceManager] setAudioRoute:TXAudioRouteEarpiece];
|
||
[[_trtcCloud getDeviceManager] setAudioRoute:TXAudioRouteSpeakerphone];
|
||
4、静音当前设备，其他人将无法听到该设备的声音 API: [_trtcCloud muteLocalAudio:YES];
|
||

Real-Time Audio Call
|
||
TRTC Audio Call
|
||
This document shows how to integrate the real-time audio call feature.
|
||
1. Switch between the speaker and receiver: [[_trtcCloud getDeviceManager] setAudioRoute:TXAudioRouteSpeakerphone]
|
||
2. Mute the device so that others won’t hear the audio of the device: [_trtcCloud muteLocalAudio:YES]
|
||
3. Display other network and volume information: delegate -> onNetworkQuality, onUserVoiceVolume
