Justin Ruggles (5):
Use av_clip_int16() in FIX15(). Output will differ now in some cases,
but the AC3 regtest is unchanged.
Use lrintf() in FIX15() macro. This matches the float-to-int16
conversion in audioconvert.c. Regression reference updated.
cosmetics: more pretty-printing
simplify precision normalization calculation
Port encode_exp() changes from Aften. 58% faster in function. old:
55303 dezicycles in encode_exp, 8191 runs, 1 skips new: 23030
