Methods and systems for encoding pictures associated with video data

A system, comprising:

• at least one processor;
• and
• a memory module comprising:
• a non-transitory computer readable storage medium storing a program for execution by the at least one processor, the program including instructions
• to:
• determine to encode a picture, based on at least one of a skip assessment associated with the picture or an encoding status of a pre-selected number of pictures preceding the picture in an encoding sequence;
• and
• encode a plurality of rows of video data associated with the picture, in response to determining to encode the picture, wherein the plurality of rows are encoded based on a pre-selected maximum encoded picture size, wherein the instructions to encode the plurality of rows of video data comprise instructions to:
• encode a first set of rows of video data of the picture at a first quantization scale;
• dynamically set a second quantization scale for encoding at least one remaining row of video data of the plurality of rows of video data of the picture, in response to determining that a number of bits associated with the pre-selected maximum encoded picture size is likely to be exceeded by encoding of the at least one remaining row of video data using the first quantization scale, based on a triangular weighting function;
• and
• encode the one or more remaining rows of video data of the picture at the second quantization scale;
• and
• a hypothetical buffer configured to store one or more encoded pictures from among pictures in the encoding sequence.

A non-transitory computer-readable storage medium storing a program for execution by at least one processor, the program including instructions for:

• determining to encode a picture based on at least one of a skip assessment associated with the picture or an encoding status of a pre-selected number of pictures preceding the picture in an encoding sequence;
• and
• encoding a plurality of rows of video data associated with the picture, in response to determining to encode the picture, wherein the plurality of rows are encoded based on a pre-selected maximum encoded picture size, wherein the instructions for encoding the plurality of rows of video data comprise instructions for:
• encoding a first set of rows of video data of the picture at a first quantization scale;
• dynamically setting a second quantization scale for encoding at least one remaining row of video data of the plurality of rows of video data of the picture, in response to determining that a number of bits associated with the pre-selected maximum encoded picture size is likely to be exceeded by encoding of the at least one remaining row of video data using the first quantization scale, based on a triangular weighting function;
• and
• encoding the one or more remaining rows of video data of the picture at the second quantization scale.
