TheTimedMediaHandler extension allows you to display audio and video files in wiki pages, using the same syntax as forimage files.It includes theVideoJS 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'sjob queue system for scheduling transcoding jobs.
For the player see:VideoJS Player.
For features of the subtitling system, seeCommons:Timed Text page.
In addition to theimage 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= andend= can also be used asquery 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 (seeMediaWiki's support matrix).Mobile support is spotty, especially on iOS.
TimedMediaHandler includes aJavaScript 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 offfmpeg in order to support encoding to WebM (with the latest version of VP9).
TimedMediaHandler folder to yourextensions/ directory.cdextensions/gitclonehttps://gerrit.wikimedia.org/r/mediawiki/extensions/TimedMediaHandlercomposer install --no-dev in the extension directory.(SeeT173141 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.
So, after installation change to the directory containing the extension e.g., "../extensions/TimedMediaHandler/" and runcomposer install --no-dev, or when updating:composer update --no-dev.
Alternatively, as well as preferably, add the lineextensions/TimedMediaHandler/composer.json to thecomposer.local.json file in the root directory of your wiki e.g.
{"extra":{"merge-plugin":{"include":["extensions/TimedMediaHandler/composer.json"]}}}
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 (seeTT29336).ConfigureLocalsettings.php with:
$wgJobTypesExcludedFromDefaultQueue[]='webVideoTranscode';$wgJobTypesExcludedFromDefaultQueue[]='webVideoTranscodePrioritized';
Setup dedicatedjobrunners and request running the jobs by the--type argument:
php./maintenance/run.phprunJobs--typewebVideoTranscodephp./maintenance/run.phprunJobs--typewebVideoTranscodePrioritized
It is very important to run these tasks as thewebserver 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.
aptinstallffmpeg
Plus, add this to yourLocalSettings.php (tested forDevuan ASCII (Archived 2018-09-23 at theWayback Machine) only):
$wgFFmpegLocation='/usr/bin/ffmpeg';
For security reasons, ffmpeg runs in an isolated container usingShellbox at Wikimedia.You will need their docker image if you want to emulate the Wikimedia setup, including their Debian version, dependencies, etc.Use$wgShellboxUrls to configure MediaWiki to make use of your Shellbox nodes.
You can also create your custom docker image, of course.
$dockerpulldocker-registry.wikimedia.org/wikimedia/mediawiki-libs-shellbox:videoPlease note that versions of TimedMediaHandler before MediaWiki 1.38 did not work with PostgreSQL. SeeT157424.
