Extension:TimedMediaHandler

TimedMediaHandler is an extension which allows you to display audio and video files in wiki pages, using the same syntax as for image files. It includes the kaltura html5 player, which supports integrated standard timed text support, real time stream switching between multiple WebM and Ogg derivatives and many other features. TMH server side support includes multiple transcode profiles, php based medata parsing via PEAR Ogg / OggHandler and getID3 for WebM files, and integrates with mediaWiki's jobQueue system for scheduling transcoding jobs.

Feature Overview
For now see: prototype page Also see Commons:Commons:TimedText and Multimedia_beta page.

Syntax synopsis

 * [[File:Video.ogv]] : Display a video at its nominal size. Displays a still image from the midpoint with a play button to start an embedded player.
 * [[File:Audio.oga]] : Show a placeholder for a sound file, with a play button to start an embedded player.
 * Video.ogv : Show a video in a floating thumbnail box
 * : Show a video embedded in an image gallery ( each clip will popup a dialog for the full player )
 * Video.ogg : 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.
 * Video.ogg : 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 and end time of the form end=1:30 Which would result in a clip of 5 seconds playing from 1:25 to 1:30

Client support
See bug 25370 and associated attached screen shot shows the player working in a few different browsers. A more up-to-date test using testswarm should be done.

Installation
Also see the README for detailed install instructions

Requirements
You will want a recent version of ffmpeg in order to support encoding to WebM ( with the latest version of VP8) and a copy of ffmpeg2theora to encode ogg videos. j^ supplies up-to-date static builds of ffmpeg with WebM support and of ffmpeg2theora for major OSs at firefogg.org/nightly/

To install this extension, add the following to the end of your LocalSettings.php:

Configuration
After the require line, add this to your LocalSettings.php: ( to support encoding and thumbnails )

Running transcode jobs
Because transcode jobs are resource intensive they will not run as part of normal job queue ( see bug 27336 ) Instead they must be requested by the --type argument:

Road Map

 * Add api module for listing of derivatives ( done in TimedMediaHandler )
 * Add support for transcoding from arbitrary format uploads.
 * Improve transcoding tracking with database tables for registering failed transcodes, time taken per transcode, allow users to flag files as not playable or a visually broken transcodes.
 * Improve mobile support for uploading and playback ( via native aps if the browser html5 support does not include WebM )
 * Add support for WebM flattening of edited sequences
 * Add support for mp3 uploads and audio transcoding to mp3 and ogg. ( Off by default until mp3 patents expire in 2012 )
 * Add support for IE9 video tag WebM components
