The get_TemporalSpatialTradeOff property gets the temporal-spatial tradeoff for all media streaming. A lowered tradeoff value will increase the video resolution and decrease the frame rate. Increasing the tradeoff value will increase the frame rate and decrease the video resolution. This method retrieves the temporal-spatial tradeoff set in IRTCClient::put_TemporalSpatialTradeoff.
