もし Linux コンピューターで作成したビデオを Windows や Mac OS のユーザーに送った場合、そのビデオの再生に問題が見つかるかもしれません。
ビデオを受け取った人は、ビデオを再生するために、正しいコーデックをインストールしておく必要があります。コーデックはソフトウェアのひとつです。コーデックを使うことでソフトウェアは、ビデオを扱い、スクリーンに表示することができます。ビデオフォーマットには様々な種類があり、それぞれ再生するのに個別のコーデックを必要とします。以下のようにして、ビデオのフォーマットを確認できます。
Open Files from the Activities overview.
Right-click on the video file and select Properties.
Go to the Audio/Video or Video tab and look at which Codec are listed under Video and Audio (if the video also has audio).
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 Theora 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.
If you can’t find the right codec, try the VLC media player. 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.
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).
