一般个人项目和公司项目要用不用的 user.name 和 user.email，一般情况下每次clone新项目，都要在项目根目录执行以下命令设置项目的邮箱账号信息：

git config --local user.name xxxx
git config --local user.email xxxx@yyy.com

将 webm 格式转换成 mp4 格式命令:

# 默认使用的是最高质量的转换设置
ffmpeg -i input.webm output.mp4

# 如果你想要更小的文件大小，可以通过添加比特率参数来降低质量， -b:v 是视频比特率，-b:a 是音频比特率
ffmpeg -i input.webm -b:v 1M -b:a 192k output.mp4

如果上述命令返回以下错误:

[libx264 @ 0x558605199840] height not divisible by 2 (1364x1015)
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

是由于视频的宽度或高度不能被2整除。H.264 编码（在 MP4 文件中常用）需要视频的宽度和高度都能被2整除。为了修复这个错误，你可以在FFmpeg命令中加入-vf "pad=ceil(iw/2)2:ceil(ih/2)2"来强制视频的宽度和高度都是偶数。 这个设置将自动将宽度和高度调整到最接近的偶数。命令如下：

ffmpeg -i input.webm -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" output.mp4

在 Chrome 浏览器中使用以下代码:

document.body.addEventListener("touchmove", (e) => {
    console.log(e);
})

会在控制台看到一个警告信息:

[Violation] Added non-passive event listener to a scroll-blocking 'touchmove' event. Consider marking event handler as 'passive' to make the page more responsive. See https://www.chromestatus.com/feature/5745543795965952
