Detailed Description

MJPEG encoder.

Typedef Documentation

MJpegHuffmanCode

typedef struct MJpegHuffmanCode MJpegHuffmanCode

Buffer of JPEG frame data.

Optimal Huffman table generation requires the frame data to be loaded into a buffer so that the tables can be computed. There are at most mb_width*mb_height*12*64 of these per frame.

Enumeration Type Documentation

HuffmanTableOption

enum HuffmanTableOption

Enum for the Huffman encoding strategy.

Enumerator
HUFFMAN_TABLE_DEFAULT	Use the default Huffman tables.
HUFFMAN_TABLE_OPTIMAL	Compute and use optimal Huffman tables.
