This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
msRealTime is a read/write property which specifies whether or not to enable low-latency playback on the media element.
This proprietary property is specific to Internet Explorer and Microsoft Edge.
ptr = object.msRealTime;
Boolean value set to true indicates that low-latency playback will be enabled on the media element. Low-latency playback is useful in communication and some gaming scenarios, but is more demanding on power consumption and less reliable for smooth media playback.
You must set the
msRealTime before setting the
src property in code.
msRealTime should not be used in non-real-time or non-communication scenarios, such as audio and/or video playback, as this can affects playback startup latency of audio and video playback.
