| LEAD H.264 codec built a state of the art DirectShow filter for compressing and decompressing video data using H.264/AVC standard.H. 264 is the latest video standard and the most advanced and developed jointly by ITU and MPEG. H.264/AVC provides a far more efficient algorithm for compressing video than any other compression method available. It is usually outperforms all existing standards by a factor of 3-4, isæri compared to MPEG-2 Standard and Professional H.264 Encoders be It includes LEAD AAC Encoder and Multiplexer ISO. -H.264 Decoder includes LEAD AAC Decoder and ISO De-multiplexer. Controls User definable motion estimation settings balance between encoder speed and quality. -Multiple reference frames of any combination of past and future frames, provides precise interprediction and improved robustness during packet loss while streaming of pigment network or the Internet. -Unrestricted motion search using reference material can be partly outside the frame improving network performance by predicting missing data. There is only the difference between the motion vectors savings, increasing the compression ratio. -Intraprediction can do either a 4x4 or 16x16 blocks. Motion vector prediction made before the frame is prepared for compression (pre-DCT) to predict and improve the efficiency of compression. Email is more efficient because LEAD force the traditional discrete cosine transform (DCT) as integer change. LEAD H.264 Encoder calculated using Hadamard sad to increase the compression ratio. A context-dependent smoothes deblocking filter out internal edges, greatly improves the visual quality of the video. The filter strength depends on the methods and the relationship between adjacent blocks. -Dealing Context-Adaptive Variable Length Coding (CAVLC) to encode the coefficients change. -Context-Adaptive Binary Arithmetic Coding (CABAC) method continuously updated statistical frequency of incoming data and adjust the adaptive algorithm to improve compression performance. LEAD-H.264 encoder allows the user to check the number and types of frames encoded in the video stream |
