摘要 H.264具有更好的编码效率,但其高复杂度无法满足实时应用。针对低码率应用,分析各编码工具的性能并选取合理编码框架,同时利用单指令多数据(SIMD)技术并行实现快速搜索及整数变换。 H.264 achieves higher coding efficiency than other existing video coding standards greatly. But its high complexity is the difficult problem. For bit rate video application, a rational profile is selected according to analysis of main encoder tools. Fast motion search method and integer transform are implemented by using SIMD technique.
