[FFmpeg-devel] [PATCH] CONFIG_SMALL for roqaudioenc.c

[Reimar Döffinger]

Hello,
roqaudioenc uses a ca. 16kB lookup table by default, attached patch makes
it use ff_sqrt directly if CONFIG_SMALL is set.
Overall that means instead of a single table lookup it needs about
a table lookup, 2 shifts, 2 multiples, 2 adds and two branches per value
encoded.
