Abstract: The disclosed technology relates to adaptively encoding a video stream based on viewer engagement, content schedule and/or content characteristics. A system routes a video stream from a signal extractor to a first virtual encoder. The first virtual encoder is instantiated on a cloud platform and provides a first video output at a first bitrate. A second virtual encoder is instantiated on the cloud platform in response to a change in viewer count. The system routes the video stream from the signal extractor to the second virtual encoder. The second virtual encoder provides a second video output at a second bitrate. The second bitrate is different from the first bitrate.

Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. For example, the processing circuitry decodes, from a coded video bitstream, a flag that is indicative of whether applying a lossless coding mode. In response the flag being indicative of applying the lossless coding mode, the processing circuitry partitions a block into multiple blocks based on the block having at least one side that is equal to or greater than a threshold size for zeroing out a portion of the block. Thus, video quality loss due to zero out can be avoided. Then, the processing circuitry reconstructs the multiple blocks respectively from the coded video bitstream based on the lossless coding mode.

Abstract: Techniques are described using Position Dependent Intra Prediction Combination (PDPC) and multiple reference lines. For example, a video coder (e.g., an encoder and/or decoder) can predict an initial prediction sample value for a sample of a current block using an intra-prediction mode. The initial prediction sample value can be predicted from a first neighboring block and/or a second neighboring block of the current block. One or more reference sample values can be determined from at least one line of multiple lines of reference samples from the first neighboring block and/or the second neighboring block. At least one of the lines from the multiple lines used for determining the reference sample value(s) is not adjacent to the current block. A final prediction sample value can be determined for the sample of the current block, such as by modifying the initial prediction sample value using the one or more reference sample values.

Accordingly, implementations disclosed herein may raise coding efficiency of video signal by adding an intra prediction mode as a sub-macroblock type in predicting a macroblock.

The subblock characteristic indicates one of: (i) a subblock size used for generating the prediction for the sample and (ii) an interpolation filter type for the affine subblock.
