Responsive player / embed

It's not possible to change directly dynamic embed integration from KMC or admin_console ?

for example my dynamic embed :
<script src="http://media.gossiponline.net/p/101/sp/10100/embedIframeJs/uiconf_id/23448187/partner_id/101"></script>
<div id="kaltura_player_1451664158" style="width: 640px; height: 360px;"></div>
<script>
kWidget.embed({
"targetId": "kaltura_player_1451664158",
"wid": "_101",
"uiconf_id": 23448187,
"flashvars": {
"streamerType": "auto"
},
"cache_st": 1451664158,
"entry_id": "0_fw3iaji3"
});
</script>
