11. 旋转视频

实时音视频（TRTC）支持自定义控制本地画面和远程画面的旋转方向和填充模式。

自定义控制本地画面

可以通过调用 setLocalRenderParams 设置本地渲染参数。

import TRTCCloud, { 
 TRTCRenderParams, TRTCVideoRotation, TRTCVideoFillMode,
 TRTCVideoMirrorType
} from 'trtc-electron-sdk';
const trtcCloud = new TRTCCloud();
const param = new TRTCRenderParams(
 TRTCVideoRotation.TRTCVideoRotation90,
 TRTCVideoFillMode.TRTCVideoFillMode_Fill,
 TRTCVideoMirrorType.TRTCVideoMirrorType_Enable
);
trtcCloud.setLocalRenderParams(param);
const localUserDom = document.querySelector('local-user');
trtcCloud.startLocalPreview(localUserDom);

自定义控制远程画面画面

可以通过调用 setRemoteRenderParams 设置远端渲染参数。

import TRTCCloud, { 
 TRTCRenderParams, TRTCVideoRotation, TRTCVideoFillMode,
 TRTCVideoMirrorType, TRTCVideoStreamType
} from 'trtc-electron-sdk';
const trtcCloud = new TRTCCloud();
const param = new TRTCRenderParams(
 TRTCVideoRotation.TRTCVideoRotation180,
 TRTCVideoFillMode.TRTCVideoFillMode_Fill,
 TRTCVideoMirrorType.TRTCVideoMirrorType_Disable
);
const remoteUserId = 'remoteUser';
trtcCloud.setRemoteRenderParams(remoteUserId, TRTCVideoStreamType.TRTCVideoStreamTypeBig, param);
const remoteUserDom = document.querySelector('remote-user');
trtcCloud.startRemoteView(remoteUserId, remoteUserDom, TRTCVideoStreamType.TRTCVideoStreamTypeBig);
