Installation

This installation cam can be very tricky, and possibly the most difficult of all components of the Islandora stack. Please see this post regarding past installs on the Islandora Google Group for details: https://groups.google.com/forum/#!topic/islandora/wuOjmRTY5Rs

...

  • Keep original file after ingest? - Check this option to retain files uploaded to a video collection as a datastream appended to the video object.

Note

Creating OGGs locally only exists for legacy compatibility. Unless you have a very good reason for doing so, you should not use this option. If necessary, view ffmpeg2Theora documentation for more on creating OGG derivatives.

Paths to FFmpeg/Theora executables

Code Block
whereis ffmpeg ffmpeg2theora

and checking Check for binary package files located in folders called 'bin' (such as /usr/bin, /usr/local/bin, etc.).

Warning

Video conversion in any context is an extremely resource-heavy task that can be very taxing on the computer performing it. In the case of Islandora, when using these derivative creation options, the task is called upon and performed by the 'apache' user on the same server Islandora is running on and that users are performing other tasks with. When creating video derivatives on ingest, please consider either delaying ingest to a low-traffic period of time, or performing derivative creation on another machine altogether.

The Video Solution Pack includes an ingest/purge load test that is disabled and unusable by default. This particular solution pack was chosen for load testing due to the resource-heavy process of creating video derivatives and ingesting several potentially-massive files. To enable and use it:

  1. Make sure that the Testing module is enabled and that all prerequisites for derivative creation are satisfied for the Video Solution Pack.
  2. Edit the islandora_video.info file in this folder, removing the ; and whitespace before the line files[] = tests/islandora_video_load_test.test
  3. Create a folder in the the tests/fixtures/ called  called load, and place as many videos in that folder as you would like to ingest. These files all must fit within the size specified by your php.ini file's maximum post size, and they must have a file extension supported by the Video Solution Pack, otherwise they will not be picked up by the load test.
  4. Clear the Drupal cache.
