| 4 |
* Brightcove shortcode. |
| 5 |
* |
| 6 |
* Brighcove had renovated their video player embedding code since they introduced their "new studio". |
| 7 |
* See https://support.brightcove.com/en/video-cloud/docs. |
| 8 |
* The new code is not 100% backward compatible, as long as a customized player is used. |
| 9 |
* By the time I wrote this, there were about 150000+ posts embedded legacy players, so it would be a bad |
| 10 |
* idea either to introduce a new brightcove shortcode, or to break those posts completely. |
| 11 |
* |
| 12 |
* That's why we introduce a less aggressive way: leaving the old embedding code untouched, and |
| 13 |
* introduce a new set of shortcode parameters which are translated to the latest Brightcove embedding code. |
| 14 |
* |
| 15 |
* e.g. |
| 16 |
* [brightcove video_id="12345" account_id="99999"] will be translated to the latest embedding code. |
| 17 |
* [brightcove exp=627045696&vid=1415670151] or [brightcove exp=1463233149&vref=1601200825] will be translated |
| 18 |
* to the legacy code. |
