{
if (aEnabled == mSelected) {
return;
}

// If this VideoTrack is no longer in its original VideoTrackList, then
// whether it is selected or not has no effect on its original list.
if (!mList) {
return;
}
VideoTrackList& list = static_cast<VideoTrackList&>(*mList);
if (mSelected) {
uint32_t curIndex = 0;
// Unselect all video tracks except the current one.
for (uint32_t i = 0; i < list.Length(); ++i) {
if (list[i] == this) {
curIndex = i;
continue;
}

track->SetSelected(false);
}
// Set the index of selected video track to the current's index.
list.mSelectedIndex = curIndex;
} else {
list.mSelectedIndex = -1;
}
// Fire the change event at selection changes on this video track, shall
// propose a spec change later.
