CODECAPI_AVDecVideoThumbnailGenerationMode.Of these properties, the following can also be set through the ICodecAPI interface: Specifies whether the decoder exposes output types that are suitable for transcoding before other formats. Real-Time Parallel MPEG-2 Decoding in Software Angelos Bilas, Jason Fritts, Jaswinder Pal Singh Princeton University, Princeton NJ 08544 f bilascs, jefrittsee, jpscs g. Abstract The growing demand for high quality compressed video has led to an increasing need for real-time MPEG decoding at greater resolutions and picture sizes. 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. Manufacturers decide how much functionality to include in their decoders. Encoders and decoders come at a range of prices with a range of capabilities. 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. The secret of MPEG-2 is the flexibility offered to the manufacturers of the equipment, while adhering to the core MPEG-2 standard. Although a single chip can perform MPEG-2 video decoding, most digital video products still employ a second or third chip to decode the audio and system information. In this mode, the decoder initially decodes only I frames. MPEG-2 decoder requirements have been major factors enabling the decrease in cost of MPEG-2 decoder chips. 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. the MPEG-2 decoder in StreamIt and compares some of the important implementation details to a reference C implementation of the decoder. 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 most popular versions among the software users are 3.0 and 2.0. Bandisoft MPEG-1 Decoder lies within Multimedia Tools, more precisely Editors & Converters. This free program is a product of Ligos Corporation.
The decoder supports DirectX Video Acceleration (DXVA) using either Microsoft Direct3D 9 or Microsoft Direct3D 11. Commonly, this programs installer has the following filenames: Decoder.exe and LSMpgCfg.exe etc. 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.
