This streaming media driver performs video captures at 320 x 240 pixels in either RGB24 or YUV422 format using direct memory access (DMA) into capture buffers. The purpose of the sample is to demonstrate how to write a pin-centric AVStream minidriver. The sample also shows how to implement DMA by using the related functionality provided by the AVStream class driver.\n\nThis sample features enhanced parameter validation and overflow detection.\n\n## Provision a target computer\n\nAfter you've installed the sample on your host computer, run Visual Studio, and from the **File** menu, select **Open**, then **Project/Solution...**, navigate to the directory where you've copied the Avshws sample, then to the C++ folder, and select **avshws.vcxproj** (the VC++ Project).\n\nIn the **Solution Explorer** pane in Visual Studio, at the top is **Solution 'avshws'**. Right-click this and select **Configuration Manager**. Follow the instructions in [Building a Driver with Visual Studio and the WDK](https://docs.microsoft.com/windows-hardware/drivers/develop/building-a-driver) to set the platform, operating system, and debug configuration you want to use, and to build the sample. This sample project will automatically sign the driver package.\n\nProvision your target computer using instructions in, for example, [Provision a computer for driver deployment and testing](https://docs.microsoft.com/windows-hardware/drivers/gettingstarted/provision-a-target-computer-wdk-8-1). Ensure that in the **Network and Sharing Center** control panel your target computer has **Network Discovery** and **File and Printer Sharing** enabled.\n\n## Deploy the driver to the target computer\n\nNow you can deploy the Avshws driver that you've just built to the target computer, using guidance in [Deploying a Driver to a Test Computer](https://docs.microsoft.com/windows-hardware/drivers/develop/deploying-a-driver-to-a-test-computer). Specifically, find the package file under the **Package** folder in the Avshws solution. Right-click **package** and select **Properties**. Under Configuration Properties, click **Driver install** and then **Deployment**. Here you must click the check box for **Enable deployment**, and then click the button to the right of **\\**. In the next dialog you enter the **Target Computer Name** and can let the host computer automatically provision the target computer and set up debugger options.\n\nFinally, in Visual Studio, from the **Build** menu select **Deploy Solution** to deploy the sample to the target computer. On the target computer, you can see the deployed package in the **%Systemdrive%\\\\drivertest\\\\drivers** folder.\n\n## Install the driver\n\nOn the target computer, open Device Manager, and follow these steps:\n\n1. In the **Action** menu, click **Add Legacy Hardware**, and the **Add Hardware Wizard** appears. Click **Next** and then **Next** again.\n\n1. In the **Add Hardware** window, select **Show All Devices**.\n\n1. In the **Manufacturer** list in the left pane, click **Microsoft**.\n\n1. You should see the **AVStream Simulated Hardware Sample** in the **Model** pane on the right. Click this and then click **Next**.\n\n1. Click **Next** again to install the driver, and then click **Finish** to exit the wizard.\n\nThe sample driver now appears in the Device Manager console tree under **Sound, video and game controllers**. The Avshws INF file will be on the system drive at, for example, **...windows\\\\System32\\\\DriverStore\\\\FileRepository\\\\**.\n\n## Sample code hierarchy\n\n[**DriverEntry**](https://docs.microsoft.com/previous-versions//ff558717(v=vs.85)) in Device.cpp is the initial point of entry into the driver. This routine passes control to AVStream by calling the [**KsInitializeDriver**](https://docs.microsoft.com/windows-hardware/drivers/ddi/content/ks/nf-ks-ksinitializedriver) function. In this call, the minidriver passes the device descriptor, an AVStream structure that recursively defines the AVStream object hierarchy for a driver. This is common behavior for an AVStream minidriver.\n\nAt device start time, a simulated piece of capture hardware is created (the **CHardwareSimulation** class), and a DMA adapter is acquired from the operating system and is registered with AVStream by calling the [**KsDeviceRegisterAdapterObject**](https://docs.microsoft.com/windows-hardware/drivers/ddi/content/ks/nf-ks-ksdeviceregisteradapterobject) function. This call is required for a sample that performs DMA access directly into the capture buffers, instead of using DMA access to write to a common buffer. The driver creates the [KS Filter](https://docs.microsoft.com/windows-hardware/drivers/stream/ks-filters) for this device dynamically by calling the [**KsCreateFilterFactory**](https://docs.microsoft.com/windows-hardware/drivers/ddi/content/ks/nf-ks-kscreatefilterfactory) function.\n\nFilter.cpp is where the sample lays out the [**KSPIN\\_DESCRIPTOR\\_EX**](https://docs.microsoft.com/windows-hardware/drivers/ddi/content/ks/ns-ks-_kspin_descriptor_ex) structure for the single video pin. In addition, a [**KSFILTER\\_DISPATCH**](https://docs.microsoft.com/windows-hardware/drivers/ddi/content/ks/ns-ks-_ksfilter_dispatch) structure and a [**KSFILTER\\_DESCRIPTOR**](https://docs.microsoft.com/windows-hardware/drivers/ddi/content/ks/ns-ks-_ksfilter_descriptor) structure are provided in this source file. The filter dispatch provides only a create dispatch, a routine that is included in Filter.cpp. The process dispatch is provided on the pin because this is a pin-centric sample.\n\nCapture.cpp contains source for the video capture pin on the capture filter. This is where the [**KSPIN\\_DISPATCH**](https://docs.microsoft.com/windows-hardware/drivers/ddi/content/ks/ns-ks-_kspin_dispatch) structure for the unique pin is provided. This dispatch structure specifies a *Process* callback routine, also defined in this source file. This routine is where stream pointer manipulation and cloning occurs.\n\nThe process callback is one of two routines of interest in Capture.cpp that demonstrate how to perform DMA transfers with AVStream functionality. The other is the **CCapturePin::CompleteMappings** method. These two methods show how to use the queue, obtain clone pointers, use scatter/gather lists, and perform other DMA-related tasks.\n\nFor more information, see the comments in all .cpp files.\n\n## Run the sample\n\nFollow these steps to see how the sample driver functions:\n\n1. After installation has completed, access the driver through the Graphedt tool. Graphedt.exe is available in the *tools* directory of the WDK.\n\n1. Before running GraphEdit, use the regsvr32 utility to register the proppage.dll DLL and to enable GraphEdit to display property pages for some of the built-in Microsoft DirectShow filters. Open an elevated command window with Administrator privileges, and navigate to the WDK or SDK *tools* directory that contains proppage.dll.\n\n1. On the command line, type regsvr32 proppage.dll. If the registration succeeds, you'll get a message, \"DllRegisterServer in proppage.dll succeeded.\" Click OK.\n\n1. In the Graphedt tool, click the **Graph** menu and click **Insert Filters**. The sample appears under \"WDM Streaming Capture Devices\" as \"avshws Source.\"\n\n1. Click **Insert Filter**. The sample appears in the graph as a single filter labeled, \"avshws Source.\" There is one output pin, which is the video capture pin. This pin emits video in YUY2 format.\n\n1. Attach this filter to either a DirectShow Video Renderer or to the VMR default video renderer. Then click **Play**.\n\nThe output that is produced by the sample is a 320 x 240 pixel image of standard EIA-189-A color bars. In the middle of the image near the bottom, a clock appears over the image. This clock displays the elapsed time since the graph was introduced into the run state following the last stop. The clock display format is MINUTES:SECONDS.HUNDREDTHS.\n\nIn the upper-left corner of the image, a counter counts the number of frames that have been dropped since the graph was introduced into the run state after the last stop.\n\n## File manifest\n\n| File | Description |\n| --- | --- |\n| Avshws.h | Main header file for the sample |\n| Avshws.inf | Sample installation file |\n" }, { "path": "Driver/avshws/avshws.h", "content": "/**************************************************************************\n\n AVStream Simulated Hardware Sample\n\n Copyright (c) 2001, Microsoft Corporation.\n\n File:\n\n avshws.h\n\n Abstract:\n\n AVStream Simulated Hardware Sample header file.

Abstract:\n\n This file contains source for the video capture pin on the capture\n filter. The capture sample performs \"fake\" DMA directly into\n the capture buffers. Common buffer DMA will work slightly differently.\n\n For common buffer DMA, the general technique would be DPC schedules\n processing with KsPinAttemptProcessing. The processing routine grabs\n the leading edge, copies data out of the common buffer and advances.\n Cloning would not be necessary with this technique. It would be \n similiar to the way \"AVSSamp\" works, but it would be pin-centric.\n\n History:\n\n created 3/8/2001\n\n**************************************************************************/\n\n#include \"avshws.h\"\n#include \n#include \n\n/**************************************************************************\n\n PAGEABLE CODE\n\n**************************************************************************/\n\n\n#ifdef ALLOC_PRAGMA\n#pragma code_seg(\"PAGE\")\n#endif // ALLOC_PRAGMA\n\n//OG: 320x240\n#define DMAX_X 1280\n#define DMAX_Y 720\n#define D_X 1280\n#define D_Y 720\n\nCCapturePin::\nCCapturePin (\n IN PKSPIN Pin\n ) :\n m_Pin (Pin)\n ,m_PresentationTime (0)\n\n/*++\n\nRoutine Description:\n\n Construct a new capture pin.\n\nArguments:\n\n Pin -\n The AVStream pin object corresponding to the capture pin\n\nReturn Value:\n\n None\n\n--*/\n\n{\n\n PAGED_CODE();\n\n PKSDEVICE Device = KsPinGetDevice (Pin);\n\n //\n // Set up our device pointer.

The apps are based on the **driver interface library** which handles enumerating devices and setting the value of the property. This is written in VC++.\n\nThere are two example applications:\n* **UserDriverStaticImage**: This app can push static images to the driver.\n* **UserDriverCanon**: This application can push the live view of a Canon EOS camera to the driver, essentially turning it into a webcam.
