Match the use of AV_PIX_FMT_PAL8 for 1-bit QuickTime Animation in

QuickTime, merely bi-level. The two colors can be any color. The palette,
either included in the sample description, or the default Macintosh
palette (black & white for 1-bit video) will be set in lavf/qtpalette.

60a76f8be8 AAC encoder: enforce SF delta in PNS and IS SFs
Make sure to properly enforce maximum scalefactor delta in PNS
and I/S, not as an absolute range but relative to the previous
and first scalefactor, the latter important since PNS uses an
implicit inicial scalefactor derived from the global gain, and
encoded in a different way, which makes a big difference in the
allowed range.

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
