Abstract: A prediction block is determined for a current block of a current frame of a video stream using a template having pixel locations that conform to a subset of the pixel locations of the current block. A first portion of the prediction block having the same pattern of pixel locations as the template is populated by inter-predicted pixel values, and the remaining portion of the prediction block is populated by intra-predicted pixel values. The intra-predicted pixel values may be determined using inter-predicted pixel values of the first portion, pixel values of pixels adjacent to the current block, or both.

Abstract: Methods and systems for encoder parameter setting optimization. A media item to be provided to one or more users of a platform is identified. The media item is associated with a media class. An indication of the identified media item is provided as input to a first machine learning model. The first machine learning model is trained to predict, for a given media item, a set of encoder parameter settings that satisfy a performance criterion in view of a respective media class associated with the given media item. One or more outputs of the first machine learning model are obtained. The one or more obtained outputs include encoder data identifying one or more sets of encoder parameter settings and, for each of the sets of encoder parameter settings, an indication of a level of confidence that a respective set of encoder parameter settings satisfies the performance criterion in view of the media class associated with the identified media item. The identified media item is encoded using the respective set of encoding parameter settings associated with the level of confidence that satisfies a confidence criterion.

Abstract: Video coding may include identifying an input frame from an input video stream, generating, by a processor, an output bitstream by encoding the input frame, wherein encoding the input frame includes dividing the input frame into at least a first contiguous area of the input frame and a second contiguous area of the input frame, generating first encoded data by encoding the first contiguous area of the input frame, generating second encoded data by encoding the second contiguous area of the input frame, wherein encoding the second contiguous area of the input frame is performed independently of encoding the first contiguous area of the input frame, and including the first encoded data and the second encoded data in the output bitstream, and outputting the output bitstream.

Abstract: Video coding using constructed reference frames may include generating, by a processor in response to instructions stored on a non-transitory computer readable medium, a reconstructed video. Generating the reconstructed video may include receiving an encoded bitstream. Video coding using constructed reference frames may include generating a reconstructed non-showable reference frame. Generating the reconstructed non-showable reference frame may include decoding a first encoded frame from the encoded bitstream. Video coding using constructed reference frames may include generating a reconstructed frame. Generating the reconstructed frame may include decoding a second encoded frame from the encoded bitstream using the reconstructed non-showable reference frame as a reference frame. Video coding using constructed reference frames may include including the reconstructed frame in the reconstructed video and outputting the reconstructed video.
