QtrleEncContext Struct Reference

Data Fields
AVCodecContext *	avctx
int	pixel_size
AVPicture	previous_frame
unsigned int	max_buf_size
int	logical_width
signed char *	rlecode_table
	This array will contain at ith position the value of the best RLE code if the line started at pixel i There can be 3 values : skip (0) : skip as much as possible pixels because they are equal to the previous frame ones repeat (<-1) : repeat that pixel -rle_code times, still as much as possible copy (>0) : copy the raw next rle_code pixels.
int *	length_table
	This array will contain the length of the best rle encoding of the line starting at ith pixel.
uint8_t *	skip_table
	Will contain at ith position the number of consecutive pixels equal to the previous frame starting from pixel i.
