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).
