No scalability or 4:2:2 support (only 4:2:0) It supports the following MPEG-2 profiles and levels: Profile The MPEG-2 Video Encoder can produce the following kinds of output: MEDIATYPE_Stream, MEDIASUBTYPE_MPEG2_VIDEO MEDIATYPE_Stream, MEDIASUBTYPE_MPEG2_PROGRAM MEDIATYPE_Stream, MEDIASUBTYPE_MPEG2_TRANSPORT MEDIATYPE_Video, MEDIASUBTYPE_MPEG2_VIDEOĬLSID_CMPEG2EncoderVideoDS (declared in wmcodecdsp.h) MEDIATYPE_Video, MEDIASUBTYPE_I420 MEDIATYPE_Video, MEDIASUBTYPE_IYUV MEDIATYPE_Video, MEDIASUBTYPE_RGB24 MEDIATYPE_Video, MEDIASUBTYPE_UYVY MEDIATYPE_Video, MEDIASUBTYPE_YUY2 MEDIATYPE_Video, MEDIASUBTYPE_YV12 IBaseFilter ICodecAPI IEncoderAPI IMediaSeeking IVideoEncoder The decoder does not support CSS decryption or playback of encrypted DVDs.This filter is not supported on IA-64-based platforms.The decoder is not supported on IA-64–based platforms.Of these properties, the following can also be set through the ICodecAPI interface: #Microsoft mpeg 2 video decoder download windows 10 keygen![]() Specifies whether the decoder exposes output types that are suitable for transcoding before other formats. MFT_DECODER_EXPOSE_OUTPUT_TYPES_IN_NATIVE_ORDER PropertyĬODECAPI_AVDecVideoThumbnailGenerationModeĮnables or disables thumbnail generation mode.Įnables or disables hardware accelerated decoding. The decoder supports the following properties through the IMFTransform::GetAttributes method. For reverse playback, only I frames are decoded. At higher playback rates, the decoder will switch to decoding only I frames. The decoder can decode at rates faster than real time. To enable thumbnail generation mode, set the CODECAPI_AVDecVideoThumbnailGenerationMode property. If no I frame is found within a certain number of frames, the decoder starts decoding P frames and outputs non–I frames at a fixed interval (one per N pictures) until an I frame is reached. In this mode, the decoder initially decodes only I frames. This mode is intended for quick generation of thumbnail images. When this method is called, the decoder outputs only frames that fall within the range of time stamps specified by the caller. For precise seeking, call the IMFTransform::SetOutputBounds method. To enable low latency mode, set the CODECAPI_AVLowLatencyMode attribute. However, the decoder buffers fewer samples in this mode, which can potentially lead to glitches, because the decoder does not decode as many frames in advance. ![]() It reduces start-up latency, so the decoder produces the first output sample sooner. This mode is appropriate for scenarios such as real-time communications. ![]() The decoder supports DirectX Video Acceleration (DXVA) using either Microsoft Direct3D 9 or Microsoft Direct3D 11. The maximum supported resolution is 1920 × 1088 pixels. The input to the decoder must be an elementary stream. The MPEG-2 video decoder exposes the following interfaces: MFVideoFormat_I420 MFVideoFormat_IYUV MFVideoFormat_NV12 MFVideoFormat_YUY2 MFVideoFormat_YV12 The decoder supports the following output types. The decoder supports the following input media types. The decoder supports MPEG-2 Simple and Main profile video (H.262, ISO/IEC 13818-2) and MPEG-1 video (ISO/IEC 11172-2). The MPEG-2 Video Decoder is a Media Foundation transform that decodes MPEG-1 and MPEG-2 video.
