ENCODER INTERFACES DIRECTSHOW Filter The NVIDIA CUDA Video encoder DirectShow filter supports GPU accelerated H264 and VC-1 video encoding. Table 2 lists the configuration of the filter interfaces. Table 2. DirectShow Filter Interface Configuration Filter Interfaces Input pin media type Input Pin Interfaces IBaseFilter, ISpecifyPropertyPages, INVVESetting Supported types: MediaType: MEDIATYPE_VIDEO SubType: MEDIASUBTYPE_NULL Format: FORMAT_VideoInfo, FORMAT_VideoInfo2 The following subtypes are accepted: MEDIASUBTYPE_YUY2 MEDIASUBTYPE_IYUV MEDIASUBTYPE_UYVY MEDIASUBTYPE_YV12 MEDIASUBTYPE_NV12 IMemInputPin, IPin, IQualityControl Output pin media type MediaType: MEDIATYPE_Video SubType: MEDIASUBTYPE_H264 Output Pin Interfaces Filter CLSID Interface ID Property Page CLSID Executable Merit IPin, IQualityControl See Appendix A. DirectShow Filter GUIDs See Appendix A. DirectShow Filter GUIDs Property page not exposed. nvcuvenc.dll MERIT_DO_NOT_USE Visibility The NVIDIA video encoder DirectShow filter visibility is limited. It cannot be used in the GraphEdit utility. However, it can be used in a test application using the Filter GUIDs. NVIDIA CUDA VIDEO ENCODER SP04456-001_v03 | 10
ENCODER INTERFACES INVVESetting Interface DirectShow Filter INVVESetting interface can be used to get capability and set/get the encoder parameters. Table 3 lists the methods used by this interface. Table3. DirectShow Filter INVVESetting Interface Methods Methods IsSupportedCodec IsSupportedCodecProfile SetCodecType GetCodecType IsSupportedParam SetParamValue GetParamValue SetDefaultParam GetSPSPPS Description Query if the codec format is supported by the encoder Query if the profile for codec format is supported by the encoder Set encoder codec format Get the current encoding format Query if the parameter type is supported Set the value of the specified parameter type Query the current value of the specified parameter type Applies default settings of the encoding format Fetches the buffer containing SPS and PPS IsSupportedCodec Description: Syntax: Parameter: Return Value: Remarks: Query if the codec format is supported by the encoder HRESULT IsSupportedCodec(DWORD dwCodecType) dwCodecType [in] Codec type support to query S_OK: The format is supported E_NOINTERFACE: The format is not supported E_FAIL: No CUDA capability present Only NV_CODEC_TYPE_H264 is supported NVIDIA CUDA VIDEO ENCODER SP04456-001_v03 | 11
