AVCodecContextavctx
 
AVFrame frame
 
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_tskip_table
 Will contain at ith position the number of consecutive pixels equal to the previous frame starting from pixel i.
