This documentation is for Release 2.0.0. For the Release 1 version of this page, see v.23 found under Page History.

Content Creation

  • An Avalon item is created every time you choose the Create menu even if you do not associate any media or metadata with the item.  These Avalon items will only be viewable by Collection Staff because they receive access status of "Collection Staff Only" by default.  Avalon items can be deleted individually. 

  • Items can be published without adding any media to them.  To keep them hidden, edit the item and then, on the Preview page, click Unpublish at the top of the item.

  • Long section titles can cause Avalon to throw an exception. To work around this problem keep section titles shorter than 32 characters.

  • Content in the batch ingest file is case sensitive. Be sure not to mix case as this might case problems with the ingest process.

Thumbnail/Poster Image

  • Poster and thumbnail images do not match. 

Group Management

  • The Manage Groups interface will allow the creation of a group name with embedded (blank) spaces, but sometimes members of that group will not have access to items in the collection. Solution: For now, don't create groups with spaces in the name–use hyphens or underscores.

  • In the Manage Groups interface it is possible for members of group_managers to delete any Ad Hoc groups even if they are not the group creator. If you do try to delete these groups, you will receive a delete confirmation message.

  • Renaming a group may remove permissions from collections and items. To fix this problem be sure to reapply any exceptions after the group has been renamed.

Player and Controls

  • If you switch streaming quality the video starts over at the beginning, for multi-section parts you need to change the quality for each section.

  • The poster images may have a strange aspect ratio when in full screen mode. This does not affect video playback which retains the correction dimensions.

  • Mobile playback uses the native interface when in fullscreen mode which means that certain controls disappear.

  • Playback does not work with MPG4 files that contain multiple tracks or disc information.  A temporary fix has been created but has not been merged into the master code.

System configurations

  • By default Matterhorn will process one item for each available core. Running too many conversation processes at the same time in Matterhorn might cause it to freeze up. This will result in unexpected failures. If this happens tweak the maximum concurrent workflows value to restore stability.

  • Uploading a file larger than the value configured in the Master File model will throw an exception instead of being gracefully handled. If routinely uploading files bigger than the default either change it or use the dropbox interface.
