The pipeline allows certain CPU intensive operations such as i. DCT, motion compensation and deinterlacing to be offloaded to the GPU. DXVA 2. 0 allows more operations, including video capturing and processing operations, to be hardware accelerated as well. DXVA works in conjunction with the video rendering model used by the video card. DXVA 1. 0, which was introduced as a standardized API with Windows 2. Windows 9. 8 or later, can use either the overlay rendering mode or VMR 79. DXVA 2. Setting up your TV tuner in Windows 7 Media Center.

Windows Vista, Windows 7, Windows 8 and later OSs, integrates with Media Foundation MF and uses the Enhanced Video Renderer EVR present in MF. OvervieweditThe DXVA is used by software video decoders to define a codec specific pipeline for hardware accelerated decoding and rendering of the codec. The pipeline starts at the CPU which is used for parsing the media stream and conversion to DXVA compatible structures. DXVA specifies a set of operations that can be hardware accelerated and device driverinterfaces DDIs that the graphic driver can implement to accelerate the operations. If the codec needs to do any of the defined operations, it can use these interfaces to access the hardware accelerated implementation of these operations. If the graphic driver does not implement one or more of the interfaces, it is up to the codec to provide a software fallback for it. The decoded video is handed over to the hardware video renderer where further video post processing might be applied to it before being rendered to the device. The resulting pipeline is usable in a Direct. Show compatible application. DXVA specifies the Motion Compensation DDI, which specifies the interfaces for i. DCT operations, Huffman coding, motion compensation, alpha blending, inverse quantization, color space conversion and frame rate conversion operations, among others. It also includes three sub specifications Deinterlacing DDI, COPP DDI and Proc. Amp DDI. 4 The Deinterlacing DDI specifies the callbacks for deinterlacing operations. The COPP Certified Output Protection Protocol DDI functions allow the pipeline to be secured for DRM protected media, by specifying encryption functions. The Proc. Amp DDI is used to accelerate post processing video. The Proc. Amp driver module sits between the hardware video renderer and the display driver and provides functions for applying post processing filters on the decompressed video. The functions exposed by DXVA DDIs are not accessible directly by a Direct. Show client, but are supplied as callback functions to the video renderer. As such, the renderer plays a very important role in anchoring the pipeline. DXVA on Windows Vista and latereditDXVA 2. DDIs, including a Capture DDI for video capture. The DDIs it shares with DXVA 1. Also, the DDI functions are directly available to callers and need not be mediated by the video renderer. As such, a program can also create a pipeline for simply decoding the media without rendering or post processing and rendering without decoding. These features require the Windows Display Driver Model drivers, which limits DXVA 2. Windows Vista, Windows Server 2. Windows 7, Windows Server 2. El Diario Del Chavo Del Ocho Descargar Pdf. R2 and Windows 8. On Windows XP and Windows 2. DXVA 1. 0. DXVA 2. Enhanced Video Renderer as the video renderer only on Vista, Windows 7, and Windows 8. With Windows XP, DXVA Rendering is possible with VMR9 and the well known Overlay Mixer. DXVA integrates with Media Foundation and allows DXVA pipelines to be exposed as Media Foundation Transforms MFTs. Even decoder pipelines or post processing pipelines can be exposed as MFTs, which can be used by the Media Foundation topology loader to create a full media playback pipeline. DXVA 1. 0 is emulated using DXVA 2. DXVA 2. 0 does not include the COPP DDI, rather it uses PVP for protected content. Windows 7 implements DXVA HD6 if the driver complies with WDDM 1. DXVA2 implementations native and copy backeditDXVA2 implementations come in two variants native and copy back. With native implementation, the decoded video stays in GPU memory until it has been displayed. The video decoder must be connected to the video renderer with no intermediary processing filter. The video renderer must also support DXVA, which gives less freedom in the choice of renderers. With copy back implementation, the decoded video is copied from GPU memory back to the CPUs memory. This implementation doesnt have the limitations mentioned above and acts similar to a normal software decoder, however video stuttering will occur if the GPU is not fast enough to copy its memory back to the CPUs memory. Native mode is advantageous unless there is a need for customized processing, as the additional copy back operations will increase GPU memory load. GPUs that should be fast enough are AMD Radeon HD 6xxx and newer. Nvidia Nvidia Ge. Force 5. 00 Series and newer. Intel Intel HD Graphics 2. SoftwareeditSee alsoeditReferenceseditExternal linksedit.
