This page is in development and will eventually contain information about supporting Video documents in EPrints.

Video Players

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.

Server Settings

The following file should contain a path to ffmpeg and ffprobe:

   /opt/eprints3/lib/syscfg.d/executables.pl

ffmpeg should be installed on the server. On some servers (Ubuntu), 'libx264' needs to be installed for the H264 codec.

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.
