mpeg4videodec: silence ubsan warning · 564dd3f0

Andreas Cadhalpun authored Jan 14, 2016

s->ac_val[0][0] is of type 'int16_t [16]', but points into a larger buffer.
Here it is used as base pointer to find the correct position in the
larger buffer by adding 's->block_index[n] * 16' and thus as 'int16_t *'.

This fixes clang's ubsan runtime error: index out of bounds for type
'int16_t [16]'

Fixes: test_case.mp4

Sample benchmark (fate flac-16-lpc-cholesky, Haswell):
old:
5993610 decicycles in ff_lpc_calc_coefs,      64 runs,      0 skips
5951528 decicycles in ff_lpc_calc_coefs,     128 runs,      0 skips
