在 lyx 演示文稿中插入视频剪辑并在 GNU/Linux 中播放

如何将视频剪辑插入到 Lyx 创建的演示文稿中？

看过http://www.latex-community。 org/forum/viewtopic.php?f=19&t=48。它可以工作，但是视频在外部播放器的后台开始。

我更喜欢在演示文稿中播放它。如果使用外部播放器，它至少应该在前台启动。但演示占据了前台。在 GNU/linux 中使用 evince 作为 pdf 查看器。 Beamer 用作演示模板。

是否可以在演示文稿本身的嵌入式播放器中播放视频文件？

创建了一个示例演示文稿。代码如下。

\documentclass[english]{beamer}
\usepackage{mathptmx}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{amsmath}
\usepackage{amssymb}

\makeatletter
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Textclass specific LaTeX commands.
 % this default might be overridden by plain title style
 \newcommand\makebeamertitle{\frame{\maketitle}}%
 \AtBeginDocument{
   \let\origtableofcontents=\tableofcontents
   \def\tableofcontents{\@ifnextchar[{\origtableofcontents}{\gobbletableofcontents}}
   \def\gobbletableofcontents#1{\origtableofcontents}
 }
 \makeatletter
 \long\def\lyxframe#1{\@lyxframe#1\@lyxframestop}%
 \def\@lyxframe{\@ifnextchar<{\@@lyxframe}{\@@lyxframe<*>}}%
 \def\@@lyxframe<#1>{\@ifnextchar[{\@@@lyxframe<#1>}{\@@@lyxframe<#1>[]}}
 \def\@@@lyxframe<#1>[{\@ifnextchar<{\@@@@@lyxframe<#1>[}{\@@@@lyxframe<#1>[<*>][}}
 \def\@@@@@lyxframe<#1>[#2]{\@ifnextchar[{\@@@@lyxframe<#1>[#2]}{\@@@@lyxframe<#1>[#2][]}}
 \long\def\@@@@lyxframe<#1>[#2][#3]#4\@lyxframestop#5\lyxframeend{%
   \frame<#1>[#2][#3]{\frametitle{#4}#5}}
 \makeatother
 \def\lyxframeend{} % In case there is a superfluous frame end

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% User specified LaTeX commands.
\usetheme{Warsaw}
\usepackage{hyperref}

\makeatother

\usepackage{babel}

\begin{document}

\title{Testing video}

\makebeamertitle

\lyxframeend{}\section{Testing video}


\lyxframeend{}\subsection{Testing video}


\lyxframeend{}\lyxframe{Testing video}

\href{run:video.wmv}{Movie}

How can I insert a video clip into a presentation created in Lyx?

Have seen http://www.latex-community.org/forum/viewtopic.php?f=19&t=48. It works, but there the video starts in the background in an external player.

I would prefer it to be played in the presentation itself. If an external player is used it it should at least start in the foreground. But the presentation takes the foreground. Using evince in GNU/linux as pdf viewer. Beamer is used as a presentation template.

Is it possible to play a video file in an embedded player in the presentation itself?

Created an example presentation. The code is found below.

看来您所要求的（现在，也许以前不是？）可以使用 Okular 作为查看器。确保在 LaTeX 序言中包含 \usepackage{multimedia} ，然后您可以在 ERT 中添加：

\movie[
height = 0.6 \textwidth, 
width = 1.0 \textwidth,
showcontrols
] 
{} {movie.mp4}

尽管 \movie< 的大多数选项都可以在我的系统上使用（在某种程度上） /code> 命令不起作用，如海报、自动启动等。但是 showcontrols 确实起作用 - 但如果电影运行完成，则控件会消失，直到演示文稿重新启动。尽管如此，我之前并不知道有什么方法可以将电影嵌入到 Linux 中，所以这只是一个开始。

根据记录，我有 Ubuntu 10.10，以及 Okular 0.11.2。我还使用 LyX 2.0.0，这是相当新的，但我认为 LyX 版本不重要。

一些有用的链接：

It seems that what you're asking for is (now, maybe not previously?) possible using Okular as the viewer. Be sure to include \usepackage{multimedia} in the LaTeX preamble, then you can add in ERT:

\movie[
height = 0.6 \textwidth, 
width = 1.0 \textwidth,
showcontrols
] 
{} {movie.mp4}

This (sort of) works on my system though most of the options for the \movie command don't work, like poster, autostart, etc. However showcontrols does work -- though if the movie runs to completion, then the controls disappear until the presentation is restarted. Nonetheless, I didn't know of any way to have movies embedded in Linux before so it's a start.

For the record I have Ubuntu 10.10, with Okular 0.11.2. I'm also using LyX 2.0.0 which is pretty new but I don't think the LyX version should matter.
