after cast initialization, sender makes request load media on running receiver var session = window.cast.framework.castcontext.getinstance().getcurrentsession(); ... session.loadmedia(loadrequest); then, receiver loads next media using mediamanager var mediamanager = new cast.receiver.mediamanager(mediaelement); ... mediamanager.load(loadrequestdata); // "loads media session on receiver without involvement of sender" i need update media session on sender side. how achieve this? you can use session.stop , addupdatelistener end current media when 1 starts. to stop, can use code snippet provided in docs: function stopapp() { session.stop(onsuccess, onerror); } you can check related so post reference. hope helps.
