FFmpeg是一套可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序。
它包括了目前领先的音/视频编码库libavcodec。
FFmpeg是在Linux下开发出来的，但它可以在包括Windows在内的大多数操作系统中编译。
这个项目是由FabriceBellard发起的，现在由MichaelNiedermayer主持。
可以轻易地实现多种视频格式之间的相互转换，例如可以将摄录下的视频avi等转成现在视频网站所采用的flv格式。

（含源码及报告）本程序分析了自2016年到2021年（外加）每年我国原油加工的产量，并且分析了2020年全国各地区原油加工量等，含饼状图，柱状图，折线图，数据在地图上显示。
运转本程序需要requests、bs4、csv、pandas、matplotlib、pyecharts库的支持，如果缺少某库请自行安装后再运转。
文件含6个excel表，若干个csv文件以及一个名字为render的html文件（需要用浏览器打开），直观的数据处理部分是图片以及html文件，可在地图中显示，数据处理的是excel文件。
不懂可以扫文件中二维码在QQ里面问。

最新版请到ffmpeg官网https://ffmpeg.org/download.html直接下载安装包，本文件包是一个ZIP包，解压直接可用，亲测。
解压完成后，别忘记配置环境变量。
FFmpeg是一套可以用来记录、转换数字音频、视频，并能将其转化为流的开源计算机程序。
采用LGPL或GPL许可证。
它提供了录制、转换以及流化音视频的完整处理方案。
它包含了非常先进的音频/视频编解码库libavcodec，为了保证高可移植性和编解码质量，libavcodec里很多code都是从头开发的。
FFmpeg在Linux平台下开发，但它同样也可以在其它操作系统环境中编译运行，包括Windows、MacOSX等。
这个项目最早由FabriceBellard发起，2004年至2015年间由MichaelNiedermayer主要负责维护。
许多FFmpeg的开发人员都来自MPlayer项目，而且当前FFmpeg也是放在MPlayer项目组的服务器上。
项目的名称来自MPEG视频编码标准，前面的"FF"代表"FastForward"。
FFmpeg编码库可以使用GPU加速。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
