obtaining training data by:
collecting information on historical requests from client devices for streaming video content, and historical content retrieval times for the historical requests; and
extracting a set of attributes from the historical requests;

training a gradient boosted tree machine learning model using the set of attributes and the historical content retrieval times to perform server-side prediction of estimated retrieval times;
receiving a new request to stream video content from a client device;
providing attributes of the new request to the gradient boosted tree machine learning model to predict an estimated retrieval time for the new request;
mapping the estimated retrieval time for the new request to a resolution for the requested video content; and
streaming the requested video content to the client device at the resolution mapped to the estimated retrieval time.
