Features

Thumbnail sprite sheet

A thumbnail sprite sheet is a big image of all thumbnails laid out on a canvas, together with a description on where every thumbnail is stored. (#4794)

The sprite sheet can be used by UI to quickly navigate through all thumbnails without having to load them one by one.

Example:

GET /item/VX-14836/thumbnail/spritesheet
Content-Type: application/xml

Self-refreshing library support for Elasticsearch

Self refreshing libraries (autoRefresh=true) is now supported for the Elasticsearch search backend. This is implemented using the Elasticsearch percolate query. (#3596)

A separate Elasticsearch index called vidispine_percolator is used to hold the percolate queries. It’s created as part of the vidispine elasticsearch init command. Systems upgrading from older VidiCore versions can use vidispine elasticsearch init --percolator-index to only create the percolator index without touching the main index.

Indexing speed improvement for Solr and Elasticsearch

 Various fixes has been made to adjust the requests that VidiCore sends to Solr and Elasticsearch, in order to improve the indexing speed. (#4777, #4850)

For Elasticsearch, it’s now possible to use multiple threads to send documents to Elasticsearch (see elasticsearchWorkerCount). It should improve the indexing speed while using Elasticsearch cluster. (#4701)

There is also a property elasticsearchBulkBuffer, which can be used to adjust the internal buffer size of the Elasticsearch worker thread. It will affect indexing speed as well.

Different handling of timecodes from scc subtitle files

Before 5.6, the timecodes of scc subtitle metadata are taken directly from the subtitle file without modification. (#4314)

In 5.6, the default behavior has been changed: the result of item.startTimecode - scc timecode will be applied to the item metadata instead. If you want to retain the old behavior, useAbsoluteSccTimeCode has to be set to true.

Possibility to override shape tag in sequence render request

When rendering a sequence, the codecs and settings in the requested shape tag definition can be overridden by the SequenceDocument. (#4506, #4507).
