  11. 11. AMF ARCHITECTURE - BASICS  Elementary data types All elementary data types are defined to make code portable to other OSs. Examples: typedef __int64 amf_int64; typedef __int32 amf_int32; typedef size_t amf_size; typedef void* amf_handle;  C++ interfaces Interfaces are implemented in the form of abstract (pure) C++ classes. Each interface is derived from the AMFInterface basic interface. It exposes methods for reference counting and querying for other interfaces : class AMFInterface { public: virtual amf_long AMF_STD_CALL Acquire()=0; virtual amf_long AMF_STD_CALL Release()=0; virtual AMF_RESULT AMF_STD_CALL QueryInterface(const AMFGuid& interfaceID, void** ppInterface) = 0; }; MEDIA SDK 1.1 AMF 11 WEBINAR | OCTOBER 22, 2014
  12. 12. AMF ARCHITECTURE – INTERFACE DIAGRAM MEDIA SDK 1.1 AMF 12 WEBINAR | OCTOBER 22, 2014 AMFInterface AMFPropertyStorage AMFData AMFProperySorageEx AMFSurface AMFBuffer AMFComponent AMFContext AMFPlane 1 1..* Component Surface
  13. 13. AMF ARCHITECTURE – PROPERTY STORAGE INTERFACE  AMFPropertyStorage implements a property map between a string ID and an AMFVariantStruct structure. There is a set of helper classes and template functions to safely manipulate AMFVariantStruct in C++. class AMFPropertyStorage : virtual public AMFInterface { public: virtual AMF_RESULT SetProperty(const wchar_t *pName, AMFVariantStruct value)=0; virtual AMF_RESULT GetProperty(const wchar_t *pName, AMFVariantStruct* pValue)=0; virtual bool HasProperty(const wchar_t *pName)=0; virtual amf_int32 GetPropertyCount() const = 0; virtual AMF_RESULT GetPropertyAt(amf_int32 index, wchar_t* name, amf_size nameSize, AMFVariantStruct* pValue) const = 0; virtual AMF_RESULT Clear()=0; virtual AMF_RESULT AddTo(AMFPropertyStorage *dest, bool bOverwrite, bool bDeep)=0; virtual AMF_RESULT CopyTo(AMFPropertyStorage *dest, bool bDeep)=0; template<typename _T> AMF_RESULT SetProperty(const wchar_t *pName, const _T& value); template<typename _T> AMF_RESULT GetProperty(const wchar_t *pName, _T* pValue); }; MEDIA SDK 1.1 AMF 13 WEBINAR | OCTOBER 22, 2014
  14. 14. AMF ARCHITECTURE – PROPERTY STORAGE EX INTERFACE AMFPropertyStorageEx adds property description and validation features to AMFPropertyStorage. class AMFPropertyStorageEx : virtual public AMFPropertyStorage { public: virtual amf_size GetPropertiesInfoCount() = 0; virtual AMF_RESULT GetPropertyInfo(amf_size szInd,const AMFPropertyInfo** pInfo) = 0; virtual AMF_RESULT GetPropertyInfo(const wchar_t *pName,const AMFPropertyInfo** pInfo)=0; virtual AMF_RESULT ValidateProperty(const wchar_t *pName, AMFVariantStruct val, AMFVariantStruct* outValidated) = 0; }; MEDIA SDK 1.1 AMF 14 WEBINAR | OCTOBER 22, 2014
  15. 15. AMF ARCHITECTURE - MEMORY  Memory AMF provides two types of memory objects: AMFBuffer and AMFSurface. Each object implements the AMFData common base interface. Each object is allocated via factory methods in the AMFContext interface. In addition, the AMFContext interface provides methods to create AMFBuffer or AMFSurface wrapping existing memory objects from various APIs: • DX9 surfaces (Win Desktop only) • DX11 Textures (Win Store and Win Desktop) • OpenCL 2D images and buffers (Win Desktop only) • OpenGL textures (Win Desktop only) • Host memory  GetNative() AMFPlane and AMFBuffer interfaces provide the GetNative() method. It allows to access the underlying memory object allocated by one of the technologies listed above. This method always return pointer to void. This call does not change the reference count of reference-counted objects (derived from the IUnknown interface or OCL’s memobj)  Thread safety All memory objects in AMF are not thread-safe (except AMF reference counting). It is assumed that any memory object is used by only one component at a time. MEDIA SDK 1.1 AMF 15 WEBINAR | OCTOBER 22, 2014
  16. 16. AMF ARCHITECTURE – DATA INTERFACE The AMFData interface is a base interface for the AMBuffer and AMFSurface interfaces. It is responsible for storing common properties of the video or audio data objects (presentation time, duration, type, etc). The AMFData interface is also responsible for memory type storage and memory conversion: class AMFData : virtual public AMFPropertyStorage { public: virtual AMF_MEMORY_TYPE GetMemoryType()=0; virtual AMF_RESULT Duplicate(AMF_MEMORY_TYPE eMemType,AMFData **ppData)=0; virtual AMF_ERROR Convert(AMF_MEMORY_TYPE eMemType)=0; virtual AMF_DATA_TYPE GetDataType()=0; virtual void SetPts(amf_pts pts)=0; virtual amf_pts GetPts()=0; virtual void SetDuration(amf_pts duration)=0; virtual amf_pts GetDuration()=0; }; MEDIA SDK 1.1 AMF 16 WEBINAR | OCTOBER 22, 2014
  17. 17. AMF ARCHITECTURE – BUFFER INTERFACE The AMFBuffer interface provides access to an unordered memory buffer. class AMFBuffer : virtual public AMFData { public: virtual amf_size GetSize()=0; virtual void* GetNative()=0; virtual void AddObserver( AMFBufferObserver* pObserver) = 0; virtual void RemoveObserver( AMFBufferObserver* pObserver) = 0; }; MEDIA SDK 1.1 AMF 17 WEBINAR | OCTOBER 22, 2014
  18. 18. AMF ARCHITECTURE – SURFACE INTERFACE The AMFSurface interface represents a video frame and consists of a collection of planes. It also holds the type of the frame: progressive, interlaced, stereoscopic, etc. class AMFSurface : virtual public AMFData { public: virtual AMF_SURFACE_FORMAT GetFormat() = 0; virtual amf_size GetPlanesCount() = 0; virtual AMFPlane* GetPlaneAt(amf_size index) = 0; virtual AMFPlane* GetPlane(AMF_PLANE_TYPE type) = 0; virtual AMF_FRAME_TYPE GetFrameType() = 0; virtual void SetFrameType(AMF_FRAME_TYPE type) = 0; virtual void AddObserver(AMFSurfaceObserver* pObserver) = 0; virtual void RemoveObserver(AMFSurfaceObserver* pObserver) = 0; }; MEDIA SDK 1.1 AMF 18 WEBINAR | OCTOBER 22, 2014
  19. 19. AMF ARCHITECTURE – PLANE INTERFACE The AMFPlane interface represents a single two-dimensional plane of a multi-plane image format or the whole image for packed image format class AMFPlane : virtual public AMFInterface { public: virtual AMF_PLANE_TYPE GetType() = 0; virtual void* GetNative() = 0; virtual amf_int32 GetPixelSizeInBytes() = 0; virtual amf_int32 GetOffsetX() = 0; virtual amf_int32 GetOffsetY() = 0; virtual amf_int32 GetWidth() = 0; virtual amf_int32 GetHeight() = 0; virtual amf_int32 GetHPitch() = 0; virtual amf_int32 GetVPitch() = 0; }; MEDIA SDK 1.1 AMF 19 WEBINAR | OCTOBER 22, 2014
  20. 20. AMF ARCHITECTURE – CONTEXT INTERFACE - DIRECTX The AMFContext interface is responsible for initializing and storing device-specific data. class AMFContext : virtual public AMFPropertyStorage { virtual AMF_RESULT AMF_STD_CALL Terminate() = 0; virtual AMF_RESULT InitDX9(void* pDX9Device) = 0; virtual void* GetDX9Device(AMF_DX_VERSION dxVersionRequired = AMF_DX9) = 0; virtual AMF_RESULT LockDX9() = 0; virtual AMF_RESULT UnlockDX9() = 0; virtual AMF_RESULT InitDX11(void* pDX11Device, AMF_DX_VERSION dxVersionRequired = AMF_DX11_0) = 0; virtual void* GetDX11Device(AMF_DX_VERSION dxVersionRequired = AMF_DX11_0) = 0; virtual AMF_RESULT LockDX11() = 0; virtual AMF_RESULT UnlockDX11() = 0; MEDIA SDK 1.1 AMF 20 WEBINAR | OCTOBER 22, 2014
  21. 21. AMF ARCHITECTURE – CONTEXT INTERFACE – OCL, OGL Context interface is responsible for initializing and storing API-specific data (OGL devices, OCL contexts). virtual AMF_RESULT InitOpenCL(void* pCommandQueue = NULL) = 0; virtual void* GetOpenCLContext() = 0; virtual void* GetOpenCLCommandQueue() = 0; virtual void* GetOpenCLDeviceID() = 0; virtual AMF_RESULT LockOpenCL() = 0; virtual AMF_RESULT UnlockOpenCL() = 0; virtual AMF_RESULT InitOpenGL(amf_handle hOpenGLContext, amf_handle hWindow, amf_handle hDC) = 0; virtual amf_handle GetOpenGLContext() = 0; virtual amf_handle GetOpenGLDrawable() = 0; virtual AMF_RESULT LockOpenGL() = 0; virtual AMF_RESULT UnlockOpenGL() = 0; MEDIA SDK 1.1 AMF 21 WEBINAR | OCTOBER 22, 2014
  22. 22. AMF ARCHITECTURE – CONTEXT INTERFACE - ALLOCATION  The AMFContext interface allows to allocate buffers and surfaces of a particular memory type. The released objects are internally cached for future reuse. virtual AMF_RESULT AllocBuffer(AMF_MEMORY_TYPE type, amf_size size, AMFBuffer** ppBuffer) = 0; virtual AMF_RESULT AllocSurface(AMF_MEMORY_TYPE type, AMF_SURFACE_FORMAT format, amf_int32 width, amf_int32 height, AMFSurface** ppSurface) = 0; MEDIA SDK 1.1 AMF 22 WEBINAR | OCTOBER 22, 2014
  23. 23. AMF ARCHITECTURE – CONTEXT INTERFACE - WRAPPING  The AMFContext interface allows to temporarily wrap an external memory object(DX, OpenCL, OpenGL or Host memory) into an AMF surface or buffer object. AMF allows to set an optional callback to track the release of AMF objects. virtual AMF_RESULT CreateBufferFromHostNative(void* pHostBuffer, amf_size size, AMFBuffer** ppBuffer, AMFBufferObserver* pObserver) = 0; virtual AMF_RESULT CreateSurfaceFromHostNative(AMF_SURFACE_FORMAT format,amf_int32 width, amf_int32 height, amf_int32 hPitch, amf_int32 vPitch, void* pData, AMFSurface** ppSurface, AMFSurfaceObserver* pObserver) = 0; virtual AMF_RESULT CreateSurfaceFromDX9Native(void* pDX9Surface, AMFSurface** ppSurface, AMFSurfaceObserver* pObserver) = 0; virtual AMF_RESULT CreateSurfaceFromDX11Native(void* pDX11Surface, AMFSurface** ppSurface, AMFSurfaceObserver* pObserver) = 0; virtual AMF_RESULT CreateSurfaceFromOpenGLNative( AMF_SURFACE_FORMAT format, amf_handle hGLTextureID, AMFSurface** ppSurface, AMFSurfaceObserver* pObserver) = 0; }; MEDIA SDK 1.1 AMF 23 WEBINAR | OCTOBER 22, 2014
  24. 24. AMF ARCHITECTURE – COMPONENT INTERFACE Each component implements a common AMFComponent interface. The AMFComponent interface is derived from AMFPropertyStorageEx and exposes a number of properties for the application to discover and manipulate. class AMFComponent : virtual public AMFPropertyStorageEx { public: virtual AMF_RESULT Init(AMF_SURFACE_FORMAT format,amf_int32 width,amf_int32 height) = 0; virtual AMF_RESULT ReInit(amf_int32 width,amf_int32 height) = 0; virtual AMF_RESULT Terminate() = 0; virtual AMF_RESULT Drain() = 0; virtual AMF_RESULT Flush() = 0; virtual AMF_RESULT SubmitInput(AMFData* pData) = 0; virtual AMF_RESULT QueryOutput(AMFData** ppData) = 0; virtual AMFContext* GetContext() = 0; virtual AMF_RESULT SetOutputDataAllocatorCB(AMFDataAllocatorCB* callback) = 0; }; MEDIA SDK 1.1 AMF 24 WEBINAR | OCTOBER 22, 2014
