# 0: standard approximation method, process blocks of level [6, 10],
# use up to 3 dictionary vectors
# 1: standard approximation method, process blocks of level [4, 12],
# use up to 5 dictionary vectors
# 2: significantly increases the approximation quality,
# running time is twice as high as with the standard method
# 3: hardly increases the approximation quality of method 2,
# running time is twice as high as with method 21
# (this method just remains for completeness)

# 0 image is processed in normal bintree order
# >0 image is subdivided into 2^`tiling-exponent' tiles.
# Set type of image tiling

# Quantization parameters define the accuracy of coefficients quantization.
# DC coefficients (of the constant dictionary vector f(x,y) = 1) are quantized
# to values of the interval [-`dc-rpf-range', `dc-rpf-range'] using

# 'fps' defines the frame rate which should be
# used when the video is decoded. This value has no effect during coding,

# motion compensated prediction is used.
# If 'cross-B-search' is set then the fast Cross-B-Search algorithm is
# used to determine the motion vectors of interpolated prediction. Otherwise

# for B frame predicion.
