requestAltrefRefresh method

void requestAltrefRefresh()

External feedback hook: force an ALTREF refresh on the next inter frame, regardless of altrefRefreshPeriod / refreshAltrefOnInter. The request is consumed on the next encoded frame (a keyframe also clears it). Use this when the receiver reports the long-term anchor is unusable.

Implementation

void requestAltrefRefresh() {
  _pendingAltrefRequest = true;
}
