Abstract: A method includes determining a tile position in a frame of a spherical video based on a view perspective, selecting a portion of the frame of the spherical video as a two dimensional tile based on the tile position, encoding the two dimensional tile at a first quality, mapping the frame of the spherical video to a two dimensional representation of the spherical video based on a two dimensional projection algorithm, and encoding the two dimensional representation of the spherical video at a second quality.

Abstract: An apparatus (e.g., a computer device) includes a video coding system. The video coding system includes an encoder. The encoder is configured to partition a block of video data into a first partition and a second partition, the first partition and the second partition being divided by a border that is at an angle to an orientation of a row or column of pixels, determine a first motion vector for the first partition and a second motion vector for the second partition, determine a first set of predictor values based on the first motion vector and a second set of predictor values based on the second motion vector, and combine the first set of predictor values and the second set of predictor values into an overall set of predictor values based on a weighting algorithm.

Abstract: Encoding and decoding using advance coded reference prediction may include identifying a sequence of temporally adjacent frames from the plurality of frames, wherein each frame in the sequence of temporally adjacent frames is associated with a respective frame position indicating a temporal location the sequence, encoding a first frame from the sequence as an intra-coded frame, generating an alternate reference frame by reconstructing the first encoded frame, encoding a second frame from the sequence with reference to a reference frame, the second frame associated with a second frame position, including the first encoded frame in a compressed bitstream at a first bitstream position, and including the second encoded frame in the compressed bitstream at a second bitstream position, wherein the second bitstream position is later than the first bitstream position and wherein the first frame position is later than the second frame position.

Abstract: Disclosed is a method including converting, during a first pass, video data from a first multi-component format to an intermediate multi-component format, the intermediate multi-component format including a first video component, the intermediate multi-component format including a second video component interleaved with a third video component, and converting, during a second pass, the video data from the intermediate multi-component format to a second multi-component format by de-interleaving the second component and third component.

Abstract: Techniques for efficient coding of video content are presented. When encoding motion vectors of a current block of a current video frame, a coder management component analyzes encoded blocks of the current frame adjacent to the current block and encoded blocks of the previous video frame that occupy locations in the previous frame corresponding to the locations of the current block and blocks adjacent to the current block. The coder management component arranges motion vectors in order as a function of spatial proximity, temporal distance between the previous frame and the current frame, and/or motion vector magnitude. The coder management component selects a coding mode, based on the order, to transmit to the decoder. A coder component encodes the current block using the motion vector associated with the coding mode.
