Abstract: Techniques for using variable refresh rate to seamlessly adapt to arbitrary and variable video frame rates are described. According to some embodiments, a computer-implemented method includes receiving, by a media player, a video entirely encoded at a fixed frame rate, decoding the encoded video into a rendered video at the fixed frame rate with a video decoder of the media player, setting a display and a display interface that is to output the rendered video to the display to a variable refresh rate mode that synchronizes a refresh rate of the display to a varying frame rate of rendered frames, sending the rendered video at the fixed frame rate from the media player to the display interface, sending the rendered video from the display interface to the display at the fixed frame rate when the display interface is in the variable refresh rate mode, and displaying the rendered video on the display at the fixed frame rate when the display is in the variable refresh rate mode.

As one example, a computer-implemented method includes receiving a request to perform a real-time encode of a live video at a content delivery service, dynamically allocating, by the content delivery service, a set of compute resources between parallel encoders to respectively encode different renditions of the live video based at least in part on real-time usage data, performing parallel real-time encoding of each of the different renditions of the live video by the set of compute resources of the content delivery service, and transmitting at least one of the encoded different renditions of the live video from the content delivery service to a viewer device.

Abstract: Techniques for a texture modification feature are described herein. First data identifying a position and a distance of an actor in an environment from a view point is obtained. The actor may correspond to a mesh comprised of a plurality of triangles. Second data identifying a location, an angle, and size for each triangle of the plurality of triangles with respect to a spectrum of pre-defined viewpoints is obtained. A value for each triangle may be determined based on the first data and the second data. The value may represent a level of detail to optimize viewing of each triangle of the actor from a corresponding viewpoint of the spectrum of pre-defined viewpoints. One or more areas of a texture that corresponds to the mesh may be modified prior to applying the texture to the mesh based on the associated values for triangles of the mesh.

Abstract: Embodiments include systems, methods, and computer-readable media for optimized reduced bitrate encoding for text-based content in video frames. Example methods may include determining that a first segment of video content includes a content scene, determining that a second segment of the video content includes text, and determining a first encoder configuration to encode the first segment of video content, where the first encoder configuration includes a first encoding parameter setting. Example methods may include determining a second encoder configuration to encode the second segment of the video content, where the second encoder configuration includes a second encoding parameter setting, encoding the first segment using the first encoder configuration, and encoding the second segment using the second encoder configuration. The first segment may be encoded at a first bitrate that is greater than a second bitrate at which the second segment is encoded.

Abstract: Systems, methods, and computer-readable media are disclosed for determining settings and parameters for presenting media content based on input data from a surrounding environment. Example methods may include determining input data such as time and brightness in an environment, determining adjusted content settings based on the input data, and causing an electronic device to adjust content settings for presenting the media content based on the input data. For example, the adjusted content settings may involve audio and/or visual settings. The systems and methods may also gradually transition the content settings based on an impending change in the environment.
