Media9 将于 2020 年 12 月淘汰。有没有在 LaTeX 中嵌入视频/音频的替代方法？

由于 Adob​​e 放弃对 Flash 的支持，Media9 将于 2020 年 12 月过时。有没有不依赖 Flash 的替代品，可以在 latex 文档中包含视频和音频？

答案1

Adobe 官方关于嵌入式多媒体支持（MP4/h.264 视频、MP3 音频）的 PDF 文档，例如https://helpx.adobe.com/acrobat/using/adding-multimedia-pdfs.html，仍然以 Flash 为中心。因此，Adobe 似乎尚未决定 Flash EOL 之后 PDF 中多媒体的未来。也许他们正在努力，但尚未向公众披露任何信息。

更新 04/2021

这是一个最小的无 Flash 视频嵌入实现，与 Adob​​e 当前向 Acrobat 用户提供的实现非常相似。

在 J. Hagemann、D. Savransky、M. Vlasák 和其他用户的帮助下错误追踪器，可以为 Acrobat Reader 制定一个可接受的解决方案，让用户通过操作系统特定的媒体播放器插件的控件来控制播放。对于也可以在 Okular PDF 查看器中播放的视频，请尝试用户建议的方法弗里茨。

为了使其在 Windows 上运行，需要对注册表进行以下调整。不幸的是，必须使用管理员权限才能完成此操作，运行（在文件资源管理器中单击）以下文件（用户找到的信息深蓝)：

通过使用屏幕注释以 pdf 格式而不是富媒体注释可以获取播放器配置和播放器交互。我发现以下解决方案满足我的需求：

\documentclass{beamer}
\usepackage{xkeyval}
\usepackage{media9}
\usetheme{CambridgeUS}
\usecolortheme{dolphin}
\usepackage{zref-abspage}

\makeatletter
\define@boolkey{simplemedia}{autoplay}{\def\simplemediaautoplay{#1}}

它基于上述无 flash 示例，可与 latex->dvips->ps2pdf 配合使用，感谢 AlexG 还与 pdflatex 配合使用（lualatex 和 xelatex 也应该可以工作）。pdf 文件可与我实际的 Acrobat Reader DC 和 Foxit Reader 一起播放（均在 Windows 下）。我的 Acobat XI（2012 年）不支持 mp4，只能播放 mp3 示例。在所有情况下，您都必须先信任该文档。

问候，弗里茨

答案3

详细说明这里和这里Flash 支持已停止。但是，Adobe Reader DC（我使用的是版本 21.001.20142）可以获取使用 mp4 视频编译的 pdf 文档。

在我的文档中，我使用了 media9 包中的以下代码片段：

        \includemedia[
    width=0.6\linewidth,
    height=0.7\linewidth,
    keepaspectratio,
    activate=pageopen,
    playbutton=fancy,
    addresource=figures/80deg90.mp4,
    flashvars={source=figures/80deg90.mp4&autoPlay=true}
    ]{}{VPlayer.swf}

我得到了一个编译好的 pdf。一开始我无法在 Adob​​e Reader DC 中看到视频，但使用中提到的设置这里，我让它工作了：

 1. Go to Windows Settings > Display > Graphic Settings > Under Choose an App/ Browse >
 2. Add Acrobat.exe and edit the default from "Let Windows decide" to Power Saving Intel.
 3. Relaunch Acrobat.
 4. Try to play video.

上一个答案的完整解决方案，你会发现这里在 overleaf 中运行。我也可以编译该文档并在 Adob​​e Reader DC 中运行它。
