工程实现中H.264视频编码算法的优化方法研究

基于H.264的计算复杂度分析,主要从以下4个方面对H.264编码器进行了优化:函数调整、帧内预测,帧间预测、模式选择。实验结果表明,优化后的H.264编码器能够达到较高的编码速度,为以后移植到DSP平台打下了基础。

Based on the computational complexity analysis of H.264 encoder, the H.264 encoder is optimized from the following four aspects：algorithms adjustment,intra/inter prediction,mode selection.The experimental results demonstrate that the optimized H.264 encoder can achieve a faster speed,which lay the foundation for migration on DSP platform.
