【米尔MYD-YG2LX开发板】在多媒体应用场景的体验-ffmpeg环境搭建与性能测试
<div class='showpostmsg'><h1><b>前言</b></h1><p >瑞萨RZ/G2L是一款工业领域高性能、超高效的芯片，具备丰富多媒体功能，显示、摄像头、音频接口资源丰富，满足人机交互和图像采集需求，适用于工业HMI、医疗、工业自动化、电力、显控终端等场景。</p>
<p >本篇就以搭建ffmpeg开发环境以及性能的测试为例,体验该开发板在多媒体等领域的应用。</p>
<h1 ><b>准备</b></h1>
<p >以下基于WIN11+WSL2环境进行开发,需要安装必备的工具链比如aarch64-linux-gnu-等，这些不再赘述。</p>
<h1 ><b>下载代码</b></h1>
<div class="parsedown-markdown">
<p>git clone <a href="https://github.com/FFmpeg/FFmpeg.git"><u>https://github.com/FFmpeg/FFmpeg.git</u></a></p>
<p >cd FFmpeg/</p>
</div>
<h1 ><b>交叉编译</b></h1>
<div class="parsedown-markdown">./configure --cross-prefix=aarch64-linux-gnu- --enable-cross-compile --target-os=linux --cc=aarch64-linux-gnu-gcc --arch=arm64 --prefix=/home/lhj/opt/ffmpeg/board --enable-ffmpeg --disable-armv5te --disable-armv6 --disable-armv6t2</div>
<p >(注意要先创建/home/lhj/opt/ffmpeg/board文件夹)</p>

<h1 ><b>总结</b></h1>
<p >本文进行了ffmpeg开发环境的搭建，并在开发板上测试了ffmpeg的性能。综上可以看出开发板的多媒体性能也是不错的，页非常适合多媒体终端的应用场景。</p>
