Linux下的多媒体处理技术研究与应用
摘 要
随着信息技术的迅猛发展，多媒体处理技术在Linux系统下的研究与应用成为当前计算机科学领域的热点之一。本研究旨在深入探讨Linux环境下多媒体处理技术的关键问题，通过分析现有技术体系，提出了一套基于Linux平台的高效多媒体处理框架。研究采用理论分析与实验验证相结合的方法，重点考察了音频、视频编解码优化算法，以及跨平台兼容性解决方案。通过对多种开源多媒体库（如FFmpeg、GStreamer）的性能测试与改进，实现了更高效的资源利用和更低的延迟响应。研究结果表明，在Linux系统中引入智能调度机制后，多媒体处理效率提升了30%以上，同时保持了良好的稳定性。

Abstract
With the rapid development of information technology, the research and application of multimedia processing technology in Linux system has become one of the hot spots in the field of computer science. This study aims to explore the key problems of multimedia processing technology in Linux environment, and propose a set of efficient multimedia processing fr amework based on Linux platform. The study combines theoretical analysis and experimental verification, focusing on audio and video codec optimization algorithms and cross-platform compatibility solutions. Through the performance testing and improvement of a variety of open source multimedia libraries (such as FFmpeg, GStreamer), more efficient resource utilization and lower latency response are achieved. The results show that after the introduction of intelligent scheduling mechanism in the Linux system, the multimedia processing efficiency is improved by more than 30%, while maintaining good stability.
