<title>Other people can't play the videos I made</title>
25
<p>If you made a video on your Linux computer and sent it to someone using
26
Windows or Mac OS, you may find that they have problems playing the video.</p>
28
<p>To be able to play your video, the person you sent it to must have the
29
right <em>codecs</em> installed. A codec is a little piece of software that
30
knows how to take the video and display it on the screen. There are lots of
31
different video formats and each requires a different codec to play it back.
32
You can check which format your video is by doing:</p>
34
<item><p>Open the <app>Files</app> application from the <gui>Activities</gui>
36
<item><p>Right-click on video file and select <gui>Properties</gui>.</p></item>
37
<item><p>Go to the <gui>Audio/Video</gui> tab and look at which
38
<gui>codec</gui> is listed under <gui>Video</gui>.</p></item>
41
<p>Ask the person having problems with playback if they have the right codec
42
installed. They may find it helpful to search the web for the name of the codec
43
plus the name of their video playback application. For example, if your video
44
uses the <em>Theora</em> format and you have a friend using Windows Media
45
Player to try and watch it, search for "theora windows media player". You will
46
often be able to download the right codec for free if it's not installed.</p>
48
<p>If you can't find the right codec, try the
49
<link href="http://www.videolan.org/vlc/">VLC media player</link>. It works on
50
Windows and Mac OS as well as Linux, and supports a lot of different video
51
formats. Failing that, try converting your video into a different format. Most
52
video editors are able to do this, and specific video converter applications are
53
available. Check the software installer application to see what's available.</p>
56
<p>There are a few other problems which might prevent someone from playing
57
your video. The video could have been damaged when you sent it to them
58
(sometimes big files aren't copied across perfectly), they could have problems
59
with their video playback application, or the video may not have been created
60
properly (there could have been some errors when you saved the video).</p>
