The second error correction code has a higher error correction capability than the first error correction code. The encoded first portion, the first parity data, and the second parity data are stored in the memory cells of the storage device.

Abstract: An original input video file is encoded using a machine learning approach. The encoder performs a detailed video analysis and selection of encoding parameters that using a machine learning algorithm improves over time. The encoding process is done using a multi-pass approach. During a first pass, the entire video file is scanned to extract video property information that does not require in-depth analyses.

The video file is into a set of time-based chunks and, in a second pass, the encoding parameters for each chunk are set and distributed to encoding nodes for parallel processing. These encoder instances probe-encode each chunk determine the level of complexity for the chunk and to derive chunk-specific encoding parameters.

Abstract: A method and apparatus to maximize video slice size is described herein. The method packs as many macroblocks as possible within a capped-size slice, while preserving user-defined quality constraints. The probability to conform to the maximum slice size constraint may be adjusted according to a user-defined parameter. The method may be integrated into a rate control process of a video encoder.

The method then proceeds to encode the current macroblock either on a condition that encoding the given number of macroblocks with the given configuration of quantization parameters falls below the size constraint of the current slice or after determining that a new slice is needed.
