This plugin contains elements for calculating metrics of video streams, intended for objective video codec comparison.
At the moment only SSIM metric is implemented (why would you need anything else anyway?).
Also contains a helper videomeasure_collector element that collects measurement events and outputs them into a file (to be used with gst-launch).
Other metrics may be implemented in the future along with a base class for all measurers.
Fixes bug #594321.
