    DirectShow provides a related set of standard Windows filters. These filter systems support a variety of data formats while offering the experienced processor a wide range of hardware options.

    Application Programming Location Microsoft DirectShow (API) is the Microsoft Windows media streaming architecture. With DirectShow you can play or record your tasks in high quality video and sound.

    DirectShow headers, collections, SDK tools, and examples are available in Windows SDK.

  • Previous versions of the DirectShow SDK were versions of the DirectX SDK. The remaining version of the DirectX SDK for DirectShow was DirectX SDK 9.0 – Update 2005 (February Update). This latest version has moved DirectShow to the Windows SDK. To re-release the DirectShow headers, libraries, and examples, download most of the Windows SDK. .

    foreword

    Before we get started, we don’t want to go deep into using DirectShow in this article. DirectShow has special potential because many of its features that could be used in games are so weird or downright useless and confusing that I don’t really intend to use them. Instead, I usually focus on setting up DirectShow and the basics that can provide quality gaming functionality.

    Since this is the future for this post, since I haven’t seen any other posts specifically related to DirectShow, there’s a good chance I’ll expand on this in the near future and maybe apply – later for more details on each. additional elements.

    This article, although inevitably limited to this one, is still written using the DirectX 8.0 In API, including the DirectShow API, which is not traditionally distributed with DirectX 8.

    vIntroducing DirectShow

    Prior to DirectX 8.0, you had to download DirectShow as a true standalone SDK, although I will be working with DirectX, version 8 of DShow. This article should give users a basic understanding of how the COM interface works.

    What is Media Foundation in zoom?

    Media Foundation (MF) is a COM-based media pipeline and framework that works with digital media on Windows Vista, Windows 7, Windows 8, Windows 8.1, and Windows 10. It includes DXVA 2.0 to offload the most of the video processing pipeline. on the device to improve performance.

    Without DirectShow, it would be difficult, if not impossible, to create an important video and play it on a TV. One option would be to leave the 3D object and render the AV interlace as a texture. However, this creates the problem of extracting sound and synchronizing a number of sources as needed. With DirectShow, all you have to do is put together control interfaces that You can enjoy video playback. DirectShow will then take care of separating the video and audio in order to keep it in sync, as well as handle a whole host of events that can happen during file playback. Of course, you can try to write your own timers and libraries to display, play and synchronize video with sound on a DirectDraw card or whatever, but that would be problematic since DirectShow already provides this functionality.

    very simple

    The very first thing your business really needs to do is create a windows registry that includes the window layout, callback registration, and glass class registration. To use DirectShow you may need dshow which is .h included in the source file and this particular project is linked to strmiids.lib

  • Next, we need to figure out which global variables we can use to control playback and customize the playback interface.

    #include
    #enable

    //Global:
    Static IGraphBuilder *pGB NULL;
    Statically IMediaControl *pMC implies NULL;
    Static = IVideoWindow *pVW NULL ;
    Static = IMediaEventEx *pME NULL;
    Statically HWND corresponds to g_hwnd = 0;

    ...

    Next, some of us need COM to run our interface. In WinMain you usually add this command:

    int PASCAL WinMain(HINSTANCE hInst, HINSTANCE hPrevInst,
    LPSTR lpCmdLine, int mCmdShow)
    Joint initialization(NULL);

    ...

    NOTE. When you’re done, you’ll most likely call CoUninitialize(); to disable it again.

    Now we need to try to create a bean interface where our organization will initialize all other objects and/or finally read the file. To initialize DirectShow, make this call:

    //Filter Plot Manager
    CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC,
    (void iid_igraphbuilder, **)&pGB);

    //Query COM interface
    pGB->QueryInterface(IID_IMediaControl, (void **)&pMC);
    pGB->QueryInterface(IID_IVideoWindow, (void **)&pVW);

    Next, let’s create a monitor. Here we simply pass the name of the document we want to play to the command and DirectShow will take care of combining all the filters for the playback information.

  • “L” is randomly used to convert the given filename from the ASCII character set to any extended character string.
  • Only the following compression types and constructs can be played from media previously subsidized by DirectShow:
    1. Microsoft Windows Media Version 7.0 Video Codec*
    2. Record video in ISO MPEG-4 1.0*
    3. Microsoft MPEG-4 3*
    4. Sipro Labs ACELP version*
    5. Windows Media Audio*
    6. MPEG Audio Layer-3 (MP3) (decompression only)
    7. Digital video (DV)
    8. MPEG-1
    9. MJPEG
    10. Indeo
    11. Voxware*
    12. Cinepack

    All we need to do now is define the window that DirectShow will create to play the video as a solid child of the window you’ve already created, and then play the file.
