event, allowing you to run code in response to non-fatal errors being thrown during media recording via a MediaRecorder
(errors that don't halt recording).
mediaRecorder.onwarning = function(event) { ... } mediaRecorder.addEventListener('warning', function(event) { ... })
... mediaRecorder.onwarning = function(e) { console.log("A warning has been raised: " + e.message); } ...
