    Abstract: In some embodiments, a method receives a plurality of video segments of a video using a plurality of computing instances and measures data received for the plurality of computing instances during a time window. A video segment for a computing instance in the plurality of computing instances is not fully downloaded during the time window. The method calculates a video delivery metric for the plurality of computing instances based on the data received and calculates an evaluation measurement based on the video delivery metric. The evaluation measurement is used to control an addition or a termination of a computing instance.

    Abstract: In some embodiments, a method receives a first set of video files at a node that delivers video files to client devices and receives a second set of video files. The second set of video files are predicted to be delivered by the node to a client device during a time period. The node receives a request for a video file from a client device and determines whether the video file is stored in the first set of video files and the second set of video files. When the video file is stored at the node, the node sends the video file from the first set of video files and the second set of video files. When the video file is not stored in the first set of video files and the second set of video files, the node sends a request for the video file to another node.

    Abstract: A method includes receiving a current block to be coded and splitting the current block into a plurality of sub-partitions. A first set of reference pixels is determined. The method processes a first sub-partition in the plurality of sub-partitions using the first set of reference pixels and a second sub-partition in the plurality of sub-partitions using the first set of reference pixels in parallel. Then, the method processes a third sub-partition in the plurality of sub-partitions based on a second set of reference pixels determined from the processing of the first sub-partition and processing a fourth sub-partition in the plurality of sub-partitions based on a third set of reference pixels determined from the processing of the second sub-partition.

    Abstract: A method includes determining a first set of reference pixels from processing of a first sub-partition of a current block and determining a second set of reference pixels from processing of a second sub-partition of the current block. The first sub-partition and the second sub-partition are processed in parallel. The method processes a third sub-partition of the current block based on the first set of reference pixels and processes a fourth sub-partition of the current block based on the second set of reference pixels.

    Abstract: In one embodiment, a method receives a first chunk in a plurality of chunks from a video. The plurality of chunks are sent to a plurality of transcoding units for transcoding in parallel. The method transcodes the first chunk at a first transcoding unit to generate a first transcoded sub-bitstream. Then, first statistical information is received from one or more second chunks being transcoded by other transcoding units. The first statistical information from the one or more second chunks is compared to second statistical information from the first chunk and it is determined whether to perform a second transcoding process based on the comparing. When the second transcoding process is to be performed, the method performs the second transcoding process with the first chunk to generate a second transcoded bitstream and outputs the second transcoded bitstream. When the second transcoding process is not to be performed, the method outputs the first transcoded sub-bitstream.
