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…
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?
Recently it was the time to sort out an issue with a video DMO, which outputs YV12 video and in the same time is capable of supporting extended video strides in order to efficiently make a direct connection to Video Mixing Renderer Filters.
