将 LaTeX 代码输出为可以嵌入视频的文件格式

如何解决将 LaTeX 代码输出为可以嵌入视频的文件格式

哪种文件格式可以编译我的 LaTeX 代码 (Beamer) 以支持幻灯片放映并支持嵌入视频？我知道您以前可以使用 PDF，但由于 Flash 的消亡，它们不再受支持。

解决方法

以下示例取自答案 https://tex.stackexchange.com/a/595106/36296，因此我将其作为社区 wiki 发布

可以使用 media4svg 生成带有嵌入媒体（如电影等）的 svg。

\documentclass[dvisvgm,hypertex,aspectratio=169]{beamer}

\usefonttheme{serif}
\usepackage[T1]{fontenc}

\begin{frame}[fragile]{Player control}

The standard player controls (option `\verb+controls+') take a lot of space of the media display. Therefore,it is not recommended to enable them. Nevertheless,interactivity is still provided through touch or left mouse button click,and through the keyboard as summarized in the table.

Click on the media display to start playback. To pause playback,press the left mouse button on the media display. Release it to resume playback. To pause playback permanently,press the left mouse button on the media display and move the mouse out while keeping the button pressed.
