/**
* Brightcove shortcode.
*
* Brighcove had renovated their video player embedding code since they introduced their "new studio".
* See https://support.brightcove.com/en/video-cloud/docs.
* The new code is not 100% backward compatible, as long as a customized player is used.
* By the time I wrote this, there were about 150000+ posts embedded legacy players, so it would be a bad
* idea either to introduce a new brightcove shortcode, or to break those posts completely.
*
* That's why we introduce a less aggressive way: leaving the old embedding code untouched, and
* introduce a new set of shortcode parameters which are translated to the latest Brightcove embedding code.
*
* e.g.
* [brightcove video_id="12345" account_id="99999"] will be translated to the latest embedding code.
* [brightcove exp=627045696&vid=1415670151] or [brightcove exp=1463233149&vref=1601200825] will be translated
* to the legacy code.
