Nvidia NVDEC (formerly known as NVCUVID [1]) is a feature in its graphics cards that performs video decoding, offloading this compute-intensive task from the CPU. [2] NVDEC is a successor of PureVideo and is available in Kepler and later NVIDIA GPUs. It is accompanied by NVENC for video encoding in Nvidia's Video Codec SDK. [2]
Nvidia also sells PureVideo decoder software which can be used with media players which use DirectShow. Systems with dual GPU's either need to configure the codec or run the application on the Nvidia GPU to utilize PureVideo. Media players which use LAV, ffdshow or Microsoft Media Foundation codecs are able to utilize PureVideo capabilities.
Transcoding (encoding) support is not exposed through any built-in Windows application but the encoder is included as a Media Foundation Transform (MFT). [5] Includes a Media Foundation-based H.264 decoder with Baseline, Main, and High profile support, up to level 5.1 [6] Includes a DirectShow filter for H.264 decoding [7]
Like most desktop hardware-accelerated encoders, Quick Sync has been praised for its speed. [5] The eighth annual MPEG-4 AVC/H.264 video codecs comparison showed that Quick Sync was comparable to x264 superfast preset in terms of speed, compression ratio and quality (); [6] tests were performed on an Intel Core i7-3770 processor.
Nvidia NVENC (short for Nvidia Encoder) [1] is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler-based GeForce 600 series in March 2012 (GT 610, GT620 and GT630 is Fermi Architecture). [2] [3]
It can be used to decode, encode and transcode ("sync") video streams, for example, a DVD or Blu-ray Disc to a format appropriate to, for example, a smartphone. Unlike video encoding on a CPU or a general-purpose GPU , Video Core Next is a dedicated hardware core on the processor die .
The UVD is based on an ATI Xilleon video processor, which is incorporated onto the same die as the GPU and is part of the ATI Avivo HD for hardware video decoding, along with the Advanced Video Processor (AVP). UVD, as stated by AMD, handles decoding of H.264/AVC, and VC-1 video codecs entirely in hardware.
Free and open-source software portal; libavcodec is a free and open-source [4] library of codecs for encoding and decoding video and audio data. [5]libavcodec is an integral part of many open-source multimedia applications and frameworks.
