Abstract: A method executed by an electronic device to optimize resource utilization while processing media workflows by a video streaming platform is disclosed. In one embodiment, a request to initiate a set of training sessions is received, and for each training session, a set of training workflows to be processed is initiated and a task graph for each training workflow is created. Then a worker of the video streaming platform is assigned to each training session. The raw performance data from each assigned worker is then collected, and a platform performance profile is generated based on the raw performance data from the each assigned worker. The platform performance profile is used to predict resource requirements of media workflows to be processed by the video streaming platform. A system to perform the method and a storage medium storing instructions to perform the method are disclosed too.

Abstract: A method and system of blurring a digital video image or video stream having a plurality of pixels, each having a value specifying color data. A particular pixel of the plurality of pixels is identified. A number of pixels from the plurality of pixels is selected. A blurred value is determined as a function of the values of the selected pixels. The value of the particular pixel is replaced with the blurred value.
