X264: a High Performance H.264/avc Encoder

Rate-Distortion-Complexity Optimization of an H.264/AVC Encoder for Real-Time Videoconferencing on a Mobile Device

This paper presents an H.264 standard-compliant video encoder optimized for region-of-interest (ROI) based coding and applied to American Sign Language (ASL) videos. Three encoding parameters are developed which allow the encoder to allocate both rate and computational resources differently between the ROI and non-ROI. An objective measure of intelligibility is included in an encoder parameter ...

Multi-Grain Parallel Accelerate System for H.264 Encoder on ULTRASPARC T2

This paper describes a multi-grain parallel accelerate system for H.264 encoder on UltraSPARC T2 processor. This system integrates pipeline parallelism, frame-level, slice-level, macroblock-level data parallelism and SIMD technology.We use x264, an H.264 video encoder to implement our parallel accelerate system. Our implementation of parallel accelerate system achieves speedup between 10.1x and...

A study on multi-screen sharing system using H.264/AVC encoder

H.264/AVC is a standard for video compression developed by the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC JTC1 Moving Picture Experts Group (MPEG). However, the computational complexity of H.264/AVC contributed a lot to the delay time of multi-screen sharing system. In this paper, the motion estimation algorithms provided in X264 have been analysed, and an optimized algorithm has b...

الگوریتم جدید انتخاب حالت داخل فریمی سریع در استاندارد کدگذاری ویدیویی H.264/AVC

By the increasing of video communication in portable and functional devices, encoders design with low complexity and high performance are required. H.264 / AVC standard offers higher compression efficiency than previous standards. But this standard by employing several powerful coding techniques, considerably increased complexity at the encoder. This paper presents a new algorithm to reduc...
