This is how much to expand buffers to account for filters seeking outside the image boundaries.

Given two intervals, make 'prev' be the previous one of 'next' in 'manager'.

4 pixels in, 2 pixels out

Applies filter on 4 pixels (p1, p0, q0 and q1)

Applies filter on 6 pixels (p2, p1, p0, q0, q1 and q2)

Special case of EncodeImageInternal() for cache-bits=0, histo_bits=31. pic and percent are for progress.

Quantizes the value up or down to a multiple of 1<<bits (or to 255), choosing the closer one, resolving ties using bankers' rounding.

Returns the exact index where array1 and array2 are different. For an index inferior or equal to best_len_match, the return value just has to be stric

Release the data contained by 'encoded_frame'.

Returns the various RLE counts

Init/Copy the common fields in score.

Insert an interval in the list contained in the manager by starting at interval_in as a hint. The intervals are sorted by start_ value.

Checks if distance between corresponding channel values of pixels a and b is within the given limit.

Checks if distance between corresponding channel values of pixels a and b is within the given limit.

Load all 4x4 pixels into a single uint8x16_t variable.

Load the bytes into the *upper* part of 16b words. That's "<< 8", basically.

Quantize the difference between the actual component value and its prediction to a multiple of quantization, working modulo 256, taking care not to cr

Grab the 'specs' (writer, *opaque, width, height...) from 'src' and copy them into 'dst'. Mark 'dst' as not owning any memory.

Store 16, 24 or 32 bits in little-endian order.

Quantize as usual, but also compute and return the quantization error. Error is already divided by DSHIFT.
