If you use GTX 950 series or higher graphics cards (Maxwell, GM20x), you will be able to use the Nvidia NVENC HEVC(H.265) encoder which is better at compression than the NVENC H.264 encoder.Дў. If you use GTX 600 series or higher graphics cards, you will be able to use the Nvidia NVENC H264 encoder which allows you to record the target with high speed, high compression ratio, and excellent quality.

The following is the set of required and optional ICodecAPI properties for encoders to pass the HCK encoder certification.I3, i5, i7 processors / HEVC: Skylake GPU The certification process should guarantee that the required properties are properly supported and, if an optional property is supported, that it is also properly supported. Certified encoders are required to support a certain set of ICodecAPI properties and can optionally support another set of properties.

If a certified hardware encoder is present, it will generally be used instead of the inbox system encoder for Media Foundation related scenarios. If the specified value is odd then the next lower even value will be used. The number of threads must be an even value. The size of a tile must bigger than or equal to 265ењ†4 pixels. The number of threads must be less than or equal to the number of logical processors. The encoder will divide the frame into tiles such that the number of threads equals the number of tiles. Sets the number of threads used to perform the compression operation. Sets whether the content is full-screen video, as opposed to screen content that might have a smaller window of video or have no video at all. This property will set a limit on the maximum QP that the encoder can use during CBR ratecontrol. This property will set a limit on the minimum QP that the encoder can use during CBR ratecontrol. When this property is set it will cause the encoder to use the specified QP to encode the next frame and all subsequent frames until a new QP is specified.

This is a VT_UI4 value.ДЇorces the encoder to code the next frame as a key frame.

Internally, this value is mapped to a smaller set of quality/speed levels supported by the encoder. At higher complexity levels, the encoder runs more slowly but produces better quality at the same bit rate. This value affects how the encoder performs various encoding operations, such as motion compensation. This is a VT_UI4 value.Д®nables or disables low-latency mode. If zero, the encoder selects the GOP size. Sets the number of pictures from one GOP header to the next, including the leading anchor but not the following one. Sets the maximum bitrate for rate control modes that allow a peak bitrate. Sets the buffer size, in bytes, for constant bit rate (CBR) encoding. Sets the average bit rate for the encoded bit stream, in bits per second. If other modes are specified, the eAVEncCommonRateControlMode_CBR rate control will be used. It supports the following properties.ДЇor the codec requirements for HCK encoder certification, see the Certified Hardware Encoder section below. The H.265 encoder implements the ICodecAPI interface for setting encoding parameters. The following methods of the ICodecAPI interface are supported for the H.265/HEVC encoder:ДЄll other ICodecAPI methods will return the error E_NOTIMPL. The following methods of the IMFTransform interface are supported for the H.265/HEVC encoder:ДЄll other IMFTransform methods will return the error E_NOTIMPL. This attribute contains the sequence header. The default value is 1:1.ДЄfter the output type is set, the video encoder updates the type by adding the MF_MT_MPEG_SEQUENCE_HEADER attribute.

For more information about profile and level constraints, refer to Annex A of ITU-T H.265. Must be MFVideoFormat_HEVC.ДЄverage encoded bit rate, in bits per second. Set the following attributes on the output media type. The encoder supports a single output subtype: Until the output type is set, the encoder's IMFTransform::SetInputType method returns MF_E_TRANSFORM_TYPE_NOT_SET. The output type must be set before the input type. The input media type must have one of the following subtypes:ДЇor more information about these subtypes, see Video Subtype GUIDs. The H.265 video encoder exposes the following interfaces: The encoder supports the following profiles: The Media Foundation H.265 video encoder is a Media Foundation Transform that supports encoding content into the H.265/HEVC format.
