A 100-lines code snippet which illustrates how a bitmap is overlaid over displayed video with Video Mixing Renderer 9 Filter using IVMRMixerBitmap9 interface. A video clip is played (default is Windows clock.avi, but you can replace it with your longer one to see overlay is really in a loop). http://code.assembla.com/…/VmrMixerBitmapSample01/… VMR9AlphaBitmap AlphaBitmap; ZeroMemory(&AlphaBitmap, sizeof AlphaBitmap);…
This is a funny one and I wonder what is exactly causing such misbehavior. An UDP broadcasting socket is being bound to IP address 192.168.0.2: __E(m_Socket.Create(SOCK_DGRAM, IPPROTO_UDP) != INVALID_SOCKET); static const DWORD g_nBroadcastValue = 1; __E(m_Socket.SetOption(SOL_SOCKET, SO_BROADCAST, &g_nBroadcastValue, sizeof g_nBroadcastValue)); ZeroMemory(&m_LocalAddress, sizeof m_LocalAddress); m_LocalAddress.sin_family = AF_INET; m_LocalAddress.sin_port = htons(nPort); // 7365 m_LocalAddress.sin_addr.S_un.S_addr = htonl(nLocalIpAddress); //…
Windows Media Codec List utility uses IWMCodecInfo interface (see also IWMCodecInfo2, IWMCodecInfo3) lists installed Windows Media Codecs and their formats and presents the findings in a convenient way. The utility gives a quick idea what a programmer would obtain through IWMCodecInfo2/IWMCodecInfo3 interfaces and what well known format structures (WM_MEDIA_TYPE, AM_MEDIA_TYPE, WAVEFORMATEX, VIDEOINFOHEADER) correspond to particular…
Among things beyond of any understanding are those presented by Asustek/Asus engineers. While hardware is more or less OK, software is often confusing. Asus Eee PC 1000HE, out of which I own one, comes with Asus Eee PC Tray Utility 5.1.1.4008. A helper application to provide quick access to certain hardware control functions, it is…
One of the DirectShow’s most important features is Intelligent Connect, which allows Filter Graph Manager to build graphs out of independent filters trying to connect them together including options to fall back to originally non-preferred alternatives and so on. It is however important that filters are properly registered with the Filter Mapper. For the developers…
Media Tools DirectShow Filters can be used to acquire, parse and decoder M-JPEG encoded video stream from an IP camera or a video server, however for a quick start it is necessary to properly register filters on system and create a DirectShow graph. To register the filters, it is necessary to download DLLs from repository.…
Given the combo box initialization code: m_ComboBox.SetRedraw(FALSE); m_ComboBox.ResetContent(); for(INT nIndex = 0; nIndex < 3; nIndex++) m_ComboBox.AddString(AtlFormatString(_T(“Item %d”), nIndex + 1)); m_ComboBox.SetCurSel(1); m_ComboBox.SetRedraw(TRUE) How the combo box is going to look like?
