Rozszerzenie TimedMediaHandler umożliwia wyświetlenie plików audio i video na stronach wikimediów, z zastosowaniem tej samej składni, jaka występuje na ilustracjach przedstawionych w plikach. 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.
Feature overview
For the player see: VideoJS Player.
For features of the subtitling system, see Commons:Timed Text page.
Syntax synopsis
In addition to the image embed syntax, Timed Media Handler supports:
- [[File:Video.ogv]]
- Display a video at its nominal size. Displays a still image from the midpoint with a play button to start a pop-up video player.
- [[File:Audio.oga]]
- Show a placeholder for a sound file with a play button. The player will appear inline or as a pop-up if the audio file has closed captioning/subtitles.
- [[File:Midi.mid]]
- Generate digital audio from the music instructions in the MIDI file and show the embedded audio player to play this audio.
- [[File:Video.ogv|thumb]]
- Show a video in a floating thumbnail box
<gallery>File:Video.ogv</gallery>
- Show a video embedded in an image gallery (each clip will popup a dialog for the full player)
- [[File:Video.ogg|thumbtime=1:25]]
- Use a frame from 1 minute 25 seconds into the video as the placeholder image. A single number is taken as an offset in seconds. One can also use HH:MM:SS, e.g., 1:02:22 will be 1 hour, 2 minutes, and 22 seconds into the video. Floating-point seconds are supported (but broken on Wikimedia wikis: phab:T228467).
- [[File:Video.ogg|start=1:25]]
- Temporal media fragments displays a video clip starting at 1 minute 25 seconds into the video. A single number is taken as an offset in seconds. You can also include an end time of the form
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 as query parameters in the URL for a video's file page.- [[File:Video.ogg|muted]]
- Start the media with muted audio. (wprowadzono w 1.39)
- [[File:Video.ogg|loop]]
- Loop the video continuously. (wprowadzono w 1.39)
- Deprecated
- The syntax words noicon and noplayer are deprecated and do not function. The keyword disablecontrols will likely be deprecated. (Zobacz task T135537) It takes a comma-separated list of any of the following values: options, timedText, fullscreen
Client support
[[File:Videoonwikipedia.ogv|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.
Instalacja
You will want a recent version of ffmpeg in order to support encoding to WebM (with the latest version of VP9).

.
Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/TimedMediaHandler - Tylko w przypadku instalacji z repozytorium git należy uruchomić Composer, aby zainstalować zależności PHP, poprzez wywołanie
composer install --no-dev
w katalogu rozszerzenia. (Zobacz zadanie T173141 w celu uzyskania informacji o możliwych komplikacjach.) - Dodaj poniższy kod na dole twojego pliku LocalSettings.php :
wfLoadExtension( 'TimedMediaHandler' ); $wgFFmpegLocation = '/usr/bin/ffmpeg'; // Most common ffmpeg path on Linux
- Uruchom skrypt aktualizujący, który automatycznie stworzy potrzebne tabele dla tego rozszerzenia.
- Configure as required.
- You may need to increase the allowed memory in $wgMaxShellMemory .
- Zrobione – Przejdź do Special:Version na twojej wiki, aby sprawdzić czy rozszerzenie zostało pomyślnie zainstalowane.
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"
]
}
}
}

// for that media embed.

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.
Running transcode jobs
Because transcode jobs are resource intensive, they should not run as part of the normal job queue (see task T29336).
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.
Encoding nodes
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
apt install ffmpeg
Plus, add this to your LocalSettings.php (tested for Devuan ASCII (Archived 2018-09-23 at the Wayback Machine) only):
$wgFFmpegLocation = '/usr/bin/ffmpeg';
Troubleshooting
Please note that versions of TimedMediaHandler before MediaWiki 1.38 did not work with PostgreSQL. Zobacz zadanie T157424.
