一、Windows1.屏幕共享1.1 打开屏幕共享/*
* 共享屏幕局部
*/
RECT rc;
::GetWindowRect(::GetDesktopWindow(), &rc);
AliEngineScreenShareRegion screenRegion;
screenRegion.originX = (float)rc.left;
screenRegion.originY = (float)rc.top;
screenRegion.width = (float)(rc.right - rc.left);
screenRegion.height = (float)(rc.bottom - rc.top);
AliEngineScreenShareConfig config;
config.isShareByRegion = false;
config.shareRegion = screenRegion;
mpEngine->StartScreenShareByScreenRegion(screenRegion, config);
1.2 停止屏幕共享mpEngine->StopScreenShare();2.多窗口共享2.1 枚举所有可共享的窗口或者桌面/*
mScreenShareType可赋值为AliEngineScreenShareDesktop或者AliEngineScreenShareWindow
分别代表桌面与窗口。
*/
mScreenShareType = AliEngineScreenShareDesktop ;//(或 mScreenShareType = AliEngineScreenShareWindow ; )
/*
mSourceId 上次选中的id，下面代码是填充一个comboBox列表
*/
mCurrentSourceList = mEngine->GetScreenShareSourceInfo(mScreenShareType);
if (nullptr != mCurrentSourceList)
{
for (size_t i = 0; i < mCurrentSourceList->GetCount(); i++) {
AliEngineScreenSourcInfo info = mCurrentSourceList->GetSourceInfo(i);
/*
* 如果不希望共享APP自身窗口，可以通过sourceIsSelf来区分
*/
info.sourceIsSelf
CString s = AliStringToCString(info.sourceName);
lb->AddString(s);
if (mSourceId == info.sourceId) {
lb->SetCurSel(i);
}
}
/*
* 默认选择第一个窗口或者桌面，记录ID和窗口名
*/
if (mSourceId.isEmpty() && lb->GetCount() > 0)
{
lb->SetCurSel(0);
AliEngineScreenSourcInfo info = mCurrentSourceList->GetSourceInfo(0);
mSourceId = info.sourceId;
mSourceTitle = info.sourceName;
}
}2.2 共享对应的窗口或者桌面msSourceId是共享桌面的ID，可以通过上文的枚举接口获取；
screenShareSource是配置；
AliEngineScreenShareRegion shareRegion ;
shareRegion.originX = 0.f;
shareRegion.originY = 0.f;
shareRegion.width = 640.f;
shareRegion.height = 480.f;
screenShareSource.isShareByRegion = true ;
screenShareSource.shareRegion = shareRegion;
/*
* 共享桌面
*/
mpEngine->StartScreenShareByDesktopId(atol(msSourceId.c_str()), screenShareSource);
/*
* 共享窗口
*/
mpEngine->StartScreenShareByWindowId(atol(msSourceId.c_str()), screenShareSource);
/*
* 可以显示获取共享窗口的显示范围
*/
AliEngineScreenShareRegion region;
mEngine->GetDesktopRegion(mSourceId, mSourceTitle, region);
CString resolutionMsg;
resolutionMsg.Format(_T("Resolution: %d x %d"), region.width, region.height);
((CStatic*)GetDlgItem(IDC_STATIC_SCREEN_SOURCE_RESOLUTION))->SetWindowTextW(resolutionMsg);
((CEdit*)GetDlgItem(IDC_EDIT_SHARE_REGION_X))->SetWindowTextW(std::to_wstring(mScreenShareSource.shareRegion.originX).c_str());
((CEdit*)GetDlgItem(IDC_EDIT_SHARE_REGION_Y))->SetWindowTextW(std::to_wstring(mScreenShareSource.shareRegion.originY).c_str());
((CEdit*)GetDlgItem(IDC_EDIT_SHARE_REGION_X2))->SetWindowTextW(std::to_wstring(mScreenShareSource.shareRegion.width).c_str());
((CEdit*)GetDlgItem(IDC_EDIT_SHARE_REGION_Y2))->SetWindowTextW(std::to_wstring(mScreenShareSource.shareRegion.height).c_str());
}
2.3 停止共享对应的窗口或者桌面mpEngine->StopScreenShare();二、iOS1.接入方式iOS接入屏幕共享需要在原宿主 App 的基础上新建 App Extension, 并在 App Extension 中依赖 AliScreenShare.framework。
在宿主 APP 当中 embed 新建的 App Extension, 并且设置相同的 App Groups, 如果在原宿主 App 当中没有设置 App Groups, 需要在宿主 App 的 profile 当中新建 App Groups 选项。
宿主 App 和 App Extension 需要保持相同的 Bundle Id 前缀, 并使用同样的开发证书进行签名。
2.共享窗口/系统音频 AliRtcScreenShareMode mode = AliRtcScreenShareNone;
/*
* 根据需要选择性设置是否共享音频
*/
if (ctrl.shareVideo) {
mode |= AliRtcScreenShareVideo;
}
if (ctrl.shareAudioApp) {
mode |= AliRtcScreenShareAudioApp;
}
[strongSelf.engine startScreenShare:kAppGroup mode:mode];
[strongSelf.engine setAudioShareAppVolume:ctrl.appPublishVolume];3.停止共享窗口和音频[strongSelf.engine stopScreenShare];4.改变设置/* 值改变，调用相关接口 */
if (ctrl.enablePublishScreenTrackConfig) {
[strongSelf.engine setPublishVideoStreamAttribute:AliRtcVideoTrackScreen attr:@"range=mpu"];
} else {
[strongSelf.engine setPublishVideoStreamAttribute:AliRtcVideoTrackScreen attr:@""];
}
/* 停止推流，才能重新repub屏幕流 */
[strongSelf.engine stopScreenShare];
AliRtcScreenShareMode mode = AliRtcScreenShareNone;
if (ctrl.shareVideo) {
mode |= AliRtcScreenShareVideo;
}
if (ctrl.shareAudioApp) {
mode |= AliRtcScreenShareAudioApp;
}
[strongSelf.engine startScreenShare:kAppGroup mode:mode];
[strongSelf.engine setAudioShareAppVolume:ctrl.appPublishVolume];
三、Android1.共享窗口/系统音频if (config.permitScreen && config.permitAudioShare) {
mScreenShareMode = AliRtcEngine.AliRtcScreenShareMode.AliRtcScreenShareAllMode;
} else if (config.permitScreen) {
mScreenShareMode = AliRtcEngine.AliRtcScreenShareMode.AliRtcScreenShareOnlyVideoMode;
} else if (config.permitAudioShare) {
mScreenShareMode = AliRtcEngine.AliRtcScreenShareMode.AliRtcScreenShareOnlyAudioMode;
}
mAliRtcEngine.startScreenShare(null, mScreenShareMode);
2.停止共享窗口和音频pubScreenCaptureResult = mAliRtcEngine.stopScreenShare();
