  <title>Other people can’t play the videos I made</title>

  <p>如果您在 Linux 系统上制作了一个视频，并把它发送到 Windows 或 Mac OS 机子上，您可能会碰到视频播放问题。</p>

  <p>要能够播放您的视频，接收方必须安装正确的<em>编解码器</em>。编解码器是一种小软件，知道如何读取视频并在屏幕上播放该视频。有很多不同的视频格式，每种格式都需要用不同的编码解码器来播放。您可以使用下述方法了解视频的格式：</p>

  <list>
    <item>
      <p>Open <app>Files</app> from the
      <gui xref="shell-introduction#activities">Activities</gui> overview.</p>
    </item>
    <item>
      <p>Right-click on the video file and select <gui>Properties</gui>.</p>
    </item>
    <item>
      <p>Go to the <gui>Audio/Video</gui> or <gui>Video</gui> tab and look at
      which <gui>Codec</gui> are listed under <gui>Video</gui> and
      <gui>Audio</gui> (if the video also has audio).</p>
    </item>
  </list>

  <p>Ask the person having problems with playback if they have the right codec
  installed. They may find it helpful to search the web for the name of the
  codec plus the name of their video playback application. For example, if your
  video uses the <em>Theora</em> format and you have a friend using Windows
  Media Player to try and watch it, search for “theora windows media player”.
  You will often be able to download the right codec for free if it’s not
  installed.</p>

  <p>If you can’t find the right codec, try the
  <link href="http://www.videolan.org/vlc/">VLC media player</link>. It works
  on Windows and Mac OS as well as Linux, and supports a lot of different video
  formats. Failing that, try converting your video into a different format.
  Most video editors are able to do this, and specific video converter
  applications are available. Check the software installer application to see
  what’s available.</p>

  <note>
    <p>There are a few other problems which might prevent someone from playing
    your video. The video could have been damaged when you sent it to them
    (sometimes big files aren’t copied across perfectly), they could have
    problems with their video playback application, or the video may not have
    been created properly (there could have been some errors when you saved the
    video).</p>
