Video Transcoding by EPrints/FFMPEG
Are there particular video codecs/containers recommended for the streaming/seeking to work (H264 in MP4 container)? EPrints performs the following tasks when generating "thumbnails" for videos, using FFMPEG:
- generate an image thumbnail
- transcode video to ogg container
- transcode video to mp4 container
Video Document Integration
Should the video player be integrated as an iframe embed code, document "preview" or as a part of the eprint_render? Most recent version of EdShare generates a video player directly on the abstract page, rather than a document "preview". It is also possible to embed a video player (typically with an iframe) to stream content from another site, like YouTube and Vimeo.
Depositors can upload video documents. Since EPrints 3.3, there is a lightbox/flowplayer in EPrints, under /lib/static/. However, EPrints does not embed any video player as a "preview" thumbnail or on the abstract page. To generate a video player for a document in EPrints, the Kultur plugin (http://files.eprints.org/773/) can be used to extend the preview with a video player.
One solution is to integrate video.js with EPrints. Following these instructions: http://videojs.com/getting-started/ Integration involves adding the following to the <head> of the template (globally, in /archives/ARCHIVEID/lang/LANGID/templates/default.xml)
<link href="http://vjs.zencdn.net/5.11.7/video-js.css" rel="stylesheet"/> <!-- If you'd like to support IE8 --> <script src="http://vjs.zencdn.net/ie8/1.1.2/videojs-ie8.min.js"></script>
and the following right before the last closing </body> tag:
Generating the video player can be done in eprint_render.pl, as follows:
... code under review...
The following file should contain a path to ffmpeg and ffprobe:
ffmpeg should be installed on the server. On some servers (Ubuntu), 'libx264' needs to be installed for the H264 codec.
