The TimedMediaHandler extension allows you to display audio and video files in wiki pages, using the same syntax as for image files. It includes the VideoJS Player. It has support for subtitles and captions (aka Timed Text), real-time stream switching between multiple WebM and other derivatives, and many other features. TMH server-side support includes options for uploading HTML5 audio and video, multiple transcode profiles to deliver content, playback of MIDI files, metadata parsing for Ogg and WebM videos, and integration with MediaWiki's job queue system for scheduling transcoding jobs.
For new and upcoming developments in 2022 and beyond, see Extension:TimedMediaHandler/2022 work.
For the player see: VideoJS Player.
For features of the subtitling system, see Commons:Timed Text page.
In addition to the image embed syntax, Timed Media Handler supports:
<gallery>File:Video.ogv</gallery>
end=1:30 which would result in a clip of 5 seconds playing from 1:25 to 1:30. If thumbtime is not provided, the start time will be used for the displayed thumbnail. One can also use HH:MM:SS, e.g. 1:02:22 will be 1 hour, 2 minutes, and 22 seconds into the video.
start= and end= can also be used as query parameters in the URL for a video's file page.
[[File:Big Buck Bunny 4K.webm|300px|thumb|...]] [[File:example.ogg|thumb|...]] [[File:example.ogg|30px]] [[File:example.ogg]]
The player works on most modern browsers (see MediaWiki's support matrix). Mobile support is spotty, especially on iOS.
TimedMediaHandler includes a JavaScript compatibility shim for Ogg audio/video that works in Safari, Internet Explorer 10/11, and Microsoft Edge browsers.
Third-party users of MediaWiki may also wish to manually enable MP4 H.264/AAC support for native video and audio playback in Safari/IE/Edge, but when using these formats, you may need a patent license from MPEG-LA for internet broadcasting.
You will want a recent version of ffmpeg in order to support encoding to WebM (with the latest version of VP9).
TimedMediaHandler folder to your extensions/ directory.cd extensions/ git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/TimedMediaHandler
composer install --no-dev in the extension directory. (See T173141 for potential complications.)wfLoadExtension( 'TimedMediaHandler' ); $wgFFmpegLocation = '/usr/bin/ffmpeg'; // Most common ffmpeg path on Linux
The extension will automatically add supported file types (except for mp4) to $wgFileExtensions , so you do not need to add video file types manually.
After downloading this extension, please note that it requires
Composer.
So, after installation change to the directory containing the extension e.g., "../extensions/TimedMediaHandler/" and run composer install --no-dev, or when updating: composer update --no-dev.
Alternatively, as well as preferably, add the line "extensions/TimedMediaHandler/composer.json" to the "composer.local.json" file in the root directory of your wiki e.g.
{
"extra": {
"merge-plugin": {
"include": [
"extensions/TimedMediaHandler/composer.json"
]
}
}
}
Comparison of Wikipedia media encoding options[edit]
As of 2018, Wikimedia sites use VP9.

For transcoding, make sure you have $wgMaxShellMemory, $wgMaxShellTime, $wgMaxShellFileSize are large enough to allow encoding jobs to run and save output. Default values are most likely too low.
Because transcode jobs are resource intensive, they should not run as part of the normal job queue (see TT29336). Configure Localsettings.php with:
$wgJobTypesExcludedFromDefaultQueue[] = 'webVideoTranscode'; $wgJobTypesExcludedFromDefaultQueue[] = 'webVideoTranscodePrioritized';
Setup dedicated jobrunners and request running the jobs by the --type argument:
php ./maintenance/run.php runJobs --type webVideoTranscode php ./maintenance/run.php runJobs --type webVideoTranscodePrioritized
It is very important to run these tasks as the webserver user.
A single transcode job for a video can easily take an hour or longer, so ensure the commands have enough time and CPU to run.
To transcode many videos, you might want to run multiple encoding nodes that connect to the master database and access your file store directly. You will need to install ffmpeg.
Minimal install under Debian and Ubuntu[edit]Plus, add this to your LocalSettings.php (tested for Devuan ASCII (Archived 2018-09-23 at the Wayback Machine) only):
$wgFFmpegLocation = '/usr/bin/ffmpeg';Shellbox isolation[edit]
For security reasons, ffmpeg runs in an isolated container using Shellbox at Wikimedia. You will need their docker image if you want to emulate the Wikimedia setup, including their Debian version, dependencies, etc. Use $wgShellboxUrls to configure MediaWiki to make use of your Shellbox nodes.
You can also create your custom docker image, of course.
$ docker pull docker-registry.wikimedia.org/wikimedia/mediawiki-libs-shellbox:video
