拓展SOUI中SImRichEdit控件的视频OLE控件(VideoOle)

视频定位控件数据可分为两部分：

可见部分：播放按钮、加载按钮、视频第一帧图片、视频时长

不可见部分：视频URL

以下为VideoOle控件头文件部分：

 extern "C" const GUID IID_VideoOleCtrl;class RichEditVideoOle :public RichEditOleBase{DECLARE_REOBJ(RichEditVideoOle, L"video")public:enum ReVideoState{REVIDEO_STATE_NORMAL,REVIDEO_STATE_LOADING,};RichEditVideoOle();~RichEditVideoOle();BOOL InitOleWindow(IRichEditObjHost* pHost);int GetVideoState(){return _state;}SStringW GetVideoUrl(){return _video_url;}SStringW GetVideoDuration(){return _video_duration;}SStringW GetVideoId(){return GetId();}void SetVideoPlayState(ReVideoState state);protected:void UpdatePosition();bool OnBnClickPlay(SOUI::EventArgs* pEvt);protected:SOUI_ATTRS_BEGIN()ATTR_STRINGW(L"video_duration", _video_duration, FALSE)ATTR_STRINGW(L"video_url", _video_url, FALSE)ATTR_STRINGW(L"video_cover_path", _video_cover_path, FALSE)SOUI_ATTRS_END()private:int            _state;SStringW _video_duration;            //视频时长SStringW  _video_url;             //视频文件路径SStringW    _video_cover_path;          //视频第一帧图片路径};

以下为VideoOle控件的源文件部分代码：

 //// ------------------------------------------------------------------------------// impl RichEditVideoOle//// {FAB32B7E-AC02-468c-A615-1E730243B62E}static const GUID IID_VideoOleCtrl = { 0xfab32b7e, 0xac02, 0x468c, { 0xa6, 0x15, 0x1e, 0x73, 0x2, 0x43, 0xb6, 0x2e } };RichEditVideoOle::RichEditVideoOle(){_oleGuid = IID_VideoOleCtrl;_sizeNatural.cx = 300;_sizeNatural.cy = 160;_state = REVIDEO_STATE_NORMAL;_canBeSelect = FALSE;_xmlLayout = L"LAYOUT:VideoOleLayout";}RichEditVideoOle::~RichEditVideoOle(){}BOOL RichEditVideoOle::InitOleWindow(IRichEditObjHost* pHost){BOOL ret = RichEditOleBase::InitOleWindow(pHost);SWindow* pVideoWnd = _oleView.FindChildByName2<SWindow>(L"video_frame");if (pVideoWnd){SImageWnd* pVideoCoverWnd = pVideoWnd->FindChildByName2<SImageWnd>(L"video_cover_img");IBitmap* pFrameImg = SResLoadFromFile::LoadImage(_video_cover_path);if (pVideoCoverWnd && pFrameImg){pVideoCoverWnd->SetImage(pFrameImg);UpdateWindowLayout(pVideoCoverWnd);}}SImageView* pPlay = _oleView.FindChildByName2<SImageView>(L"play");ISkinObj* pPlaySkin = GETSKIN(L"skin.richvideo_play", 100);if (pPlay && pPlaySkin){pPlay->SetSkin(pPlaySkin);pPlay->SetVisible(TRUE, TRUE);pPlay->Resume();SUBSCRIBE(pPlay, EVT_CMD, RichEditVideoOle::OnBnClickPlay);}SImageView* pLoading = _oleView.FindChildByName2<SImageView>(L"loading");ISkinObj* pLoadingSkin = GETSKIN(L"skin.richvideo_loading", 100);if (pLoading && pLoadingSkin){pLoading->SetSkin(pLoadingSkin);pLoading->SetVisible(FALSE, TRUE);pLoading->Resume();}SStatic* pVideoDuration = _oleView.FindChildByName2<SStatic>(L"video_duration");if (pVideoDuration){pVideoDuration->SetWindowText(L"00:30");}return ret;}bool RichEditVideoOle::OnBnClickPlay(SOUI::EventArgs* pEvt){_state = REVIDEO_STATE_LOADING;SWindow* pVideoWnd = _oleView.FindChildByName2<SWindow>(L"video_frame");if (pVideoWnd){SImageWnd* pVideoCoverWnd = pVideoWnd->FindChildByName2<SImageWnd>(L"video_cover_img");IBitmap* pFrameImg = SResLoadFromFile::LoadImage(_video_cover_path);if (pVideoCoverWnd && pFrameImg){pVideoCoverWnd->SetImage(pFrameImg);UpdateWindowLayout(pVideoCoverWnd);}}SImageView* pPlay = _oleView.FindChildByName2<SImageView>(L"play");ISkinObj* pPlaySkin = GETSKIN(L"skin.richvideo_play", 100);if (pPlay && pPlaySkin){pPlay->SetSkin(pPlaySkin);pPlay->SetVisible(FALSE, TRUE);pPlay->Resume();}SImageView* pLoading = _oleView.FindChildByName2<SImageView>(L"loading");ISkinObj* pLoadingSkin = GETSKIN(L"skin.richvideo_loading", 100);if (pLoading && pLoadingSkin){pLoading->SetSkin(pLoadingSkin);pLoading->SetVisible(TRUE, TRUE);pLoading->Resume();}SStatic* pVideoDuration = _oleView.FindChildByName2<SStatic>(L"video_duration");if (pVideoDuration){pVideoDuration->SetWindowText(L"00:30");}_pObjHost->NotifyRichObjEvent(this, CLICK_VIDEOPLAY, 0, 0);return true;}void RichEditVideoOle::SetVideoPlayState(ReVideoState state){_state = state;if (REVIDEO_STATE_NORMAL == state){SWindow* pVideoWnd = _oleView.FindChildByName2<SWindow>(L"video_frame");if (pVideoWnd){SImageWnd* pVideoCoverWnd = pVideoWnd->FindChildByName2<SImageWnd>(L"video_cover_img");IBitmap* pFrameImg = SResLoadFromFile::LoadImage(_video_cover_path);if (pVideoCoverWnd && pFrameImg){pVideoCoverWnd->SetImage(pFrameImg);UpdateWindowLayout(pVideoCoverWnd);}}SImageView* pPlay = _oleView.FindChildByName2<SImageView>(L"play");ISkinObj* pPlaySkin = GETSKIN(L"skin.richvideo_play", 100);if (pPlay && pPlaySkin){pPlay->SetSkin(pPlaySkin);pPlay->SetVisible(TRUE, TRUE);pPlay->Resume();}SImageView* pLoading = _oleView.FindChildByName2<SImageView>(L"loading");ISkinObj* pLoadingSkin = GETSKIN(L"skin.richvideo_loading", 100);if (pLoading && pLoadingSkin){pLoading->SetSkin(pLoadingSkin);pLoading->SetVisible(FALSE, TRUE);pLoading->Resume();}SStatic* pVideoDuration = _oleView.FindChildByName2<SStatic>(L"video_duration");if (pVideoDuration){pVideoDuration->SetWindowText(L"00:30");}}}void RichEditVideoOle::UpdatePosition(){if (_spAdviseSink){_oleView.SetOleWindowRect(CRect(0, 0, 0, 0)); // 已经失效_oleView.Move(0, 0, _sizeNatural.cx, _sizeNatural.cy);CalculateExtentSize(_sizeNatural);_spAdviseSink->OnViewChange(DVASPECT_CONTENT, -1);}}

IID_VideoOleCtrl为控件GUID，可以自己生成。

接口说明：

InitOleWindow：初始化Ole窗口

GetVideoState：获取视频状态

GetVideoUrl：获取视频URL

GetVideoId：获取元素ID

GetVideoDuration：获取视频时长

OnBnClickPlay：播放按钮点击事件

void SetVideoPlayState：设置视频状态，主要是在下载完成后设置控件状态时使用

以下是布局相关xml：

<root><window pos="0,0,-0,-0" skin="skin.empty"><window name="video_frame" pos="0,0,-0,-0"><img name="video_cover_img" pos="0,0,-0,-0" /></window><image name="play" pos="130,60,-130,-60" cursor="hand" /><image name="loading" pos="130,60,-130,-60" /><window name="durationWnd" pos="0,-20,-0,-0" skin="skin.richvideo_timebg"><text name="video_duration" pos="-40,3,@40,@13" align="center" colorText="#FFFFFF" font="size:12" /></window></window>
</root>

控件需要在uires.idx文件中添加相关映射关系

注意事项跟《拓展SOUI中SImRichEdit控件的语音OLE控件(AudioOle)》中一样；

以下为使用示例代码：

        SStringW strVideo;std::string strVideoId = KfUtility::GenerateUUID();std::wstring wstrVideoId;KfUtility::ConvertUtf8ToUtf16(strVideoId, wstrVideoId);strVideo.Format(L"<video id=\"%s\" video_duration=\"120\" video_url=\"\" video_cover_path=\"D:\\imrepose\\trunk\\KFClient6\\output\\Debug_Unicode\\default_res\\location.jpg\" />", wstrAudioId.c_str());SStringW strContentVideo;strContentVideo.Format(L"<RichEditContent  type=\"ContentRight\" align=\"right\" auto-layout=\"1\">"L"<para break=\"1\" align=\"left\" />"L"<bkele data=\"avatar\" id=\"%s\" skin=\"%s\" left-pos=\"0,]-6,@40,@40\" right-pos=\"-50,]-10,@40,@40\" cursor=\"hand\" interactive=\"1\"/>"L"<para id=\"msgbody\" margin=\"65,0,45,0\" break=\"1\" simulate-align=\"1\">"        L"%s"L"</para>"L"<bkele data=\"bubble\" left-skin=\"skin_left_bubble\" right-skin=\"skin_right_otherbubble\" left-pos=\"50,{-9,[10,[10\" right-pos=\"{-10,{-9,-55,[10\" />"L"%s"L"</RichEditContent>",wstrId.c_str(), wstrFaceId.c_str(), strVideo, pEmpty);pRecvRichEdit->InsertContent(strContentVideo, RECONTENT_LAST);

控件效果图如下：
