Main, Main Still Picture, and Main10 profilesĤ096 × 2304 pixels The maximum guaranteed resolution for DXVA acceleration is 1920 × 1088 pixels at higher resolutions, decoding is done with DXVA, if it is supported by the underlying hardware, otherwise, decoding is done with software. The decoder supports the following formats: Requirement
This interface provides an alternativate API for setting the following codec properties. The H.265 decoder supports the ICodecAPI interface. Specifies the maximum number of output samples. This is a MF BLOB that is set on compressed input samples to the H.265 decoder. Indicates the lengths of NALUs in the sample. Indicates that NALU length information will be sent as a BLOB with each compressed H.265 sample. Sets the number of worker threads used by the decoder.ĬODECAPI_AVDecVideoThumbnailGenerationModeĮnables or disables thumbnail generation mode. AttributeĮnables or disables low-latency decoding mode. Applications can use this method to get or set the following attributes. The H.265 decoder implements the IMFTransform::GetAttributes method. The decoder supports the following output subtypes:įor more information about these subtypes, see Video Subtype GUIDs. For example if the content is going to be 10bit, input media type should specify the profile as Main10.
The decoder can detect in-flight output format changes based on the elementary stream syntax (aspect ratio, dimension, interlace flags, colorimetry information) and trigger corresponding output media type changes.įor input media type, the decoder expects the source to set the correct Profile. The input media types cannot change dynamically between two types. The media subtype MFVideoFormat_ HEVC_ES is to indicate the media samples carry elementary H.265 bitstream, where each sample may contain a partial picture, multiple pictures, some pictures plus a partial picture. The first media subtype, MFVideoFormat_HEVC, indicates that the media samples carry H.265 bitstream with start codes, and the stream has interleaved SPS/PPS. MFVideoFormat_HEVC or MFVideoFormat_HEVC_ES The input type must contain at least the following two attributes: Attribute To create an instance of the decoder call the MFTEnum or MFTEnumEx function. The H.265 video decoder exposes the following interfaces. The Media Foundation H.265 video decoder is a Media Foundation Transform that supports decoding H.265/HEVC content in Annex B format and can be used in playback of mp4 and m2ts files.
