The relevent extract of the iso 13818-2 about the value of the syntaxical
element top_field_first of the Picture Coding Extension is:

"top_field_first -- The meaning of this element depends upon picture_structure,
progressive_sequence and repeat_first_field.
[...]
In a field picture top_field_first shall have the value '0', and the only field
output by the decoding process is the decoded field picture."

av_fill_image_pointers()

Conversion of an out of range float to int is undefined.  Clipping to
the final range first avoids such problems.  This fixes decoding on
MIPS, which handles these conversions differently from many other CPUs.
