Methods, systems, and non-transitory computer readable storage media are disclosed for two-phase encoding a digital video based on downsampling distortion of the digital video and a constant rate factor transition threshold. For example, the disclosed system can determine a downsampling distortion indicating a measure of distortion resulting from downsampling an input digital video. The disclosed systems can utilize the downsampling distortion to determine a constant rate factor transition threshold for selecting sets of encoding parameters. For example, the disclosed systems can select a first set of encoding parameters below the constant rate factor transition threshold and a second set of encoding parameters at or above the constant rate factor transition threshold. Additionally, the disclosed systems can generate first and second sets of digital video encodings of the input digital video by utilizing the first and second sets of encoding parameters, respectively.

Systems, methods, and non-transitory computer-readable media can determine that broadcasting of a live content stream has concluded. The concluded live content stream is converted to a post live media content item. The post live media content item corresponding to the concluded live content stream is published through the social networking system. The post live media content item remains accessible through the social networking system for a pre-determined period of time.

Systems and methods for surfacing content

The present disclosure relates to systems, non-transitory computer-readable media, and methods for dynamically transitioning a digital video file between encoding states of video data encodings. For example, upon receiving an uploaded digital video file, the disclosed systems can generate an initial set of video data encodings for the digital video file in an initial state. The disclosed systems further determine a virality score associated with the digital video file. Based on the virality score, the disclosed systems determine the virality score satisfies a threshold for transitioning the digital video file from the initial state to the upgraded state and generate premium encodings for the digital video file. Similarly, based on an updated virality score or a time-based trigger, the disclosed systems can transition the digital video file from the upgraded state (or the initial state) to the maintenance state by purging one or more video data encodings.

Dynamically transitioning a digital video file between encoding states

Systems, methods, and non-transitory computer-readable media can determine at least one event generated by a content player while accessing a content item. Event information describing the at least one event can be provided to a finite-state machine being used to manage events generated by the content player. The finite-state machine is in a first state. The finite-state machine can be transitioned from the first state to a second state in response to provision of the event information. One or more actions associated with the second state can be performed based at least in part on transitioning the finite-state machine to the second state.

A first online system allows a user to create content items for presentation in a second online system without having an account in the second online system. The first online system maintains identifying information associated with users of the first online system. The first online system may also maintain a set of permissions identifying users of the first online system authorized to create content items associated with each user of the first online system. Based on the information, the first online system enables its users to create content items for presentation to users of the second online system without requiring the users to create accounts on the second online system. The content items may include one or more types of objects maintained by the first online system that help identify the user associated with the content item.
