avcodec/diracdec: Fix qfactor/offset tables · 5fbd97fc

Michael Niedermayer authored Jan 13, 2016

It seems the previous tables where calculated with 32bit integers ignoring
overflows.
Also check for the max qindex, the value is choosen so that the qfactor/offset
fit in int32.

AAC encoder: TNS fixes on short windows · 3d0849cc

Claudio Freire authored Jan 17, 2016

TNS was computing filter coefficients incorrectly for short windows
due to a few coefficient addressing bugs. Fixing them fixes lots of
instability with transients (short windows).

AAC encoder: use signed coeffs when measuring IS energy · df3fa482

Claudio Freire authored Jan 16, 2016

I/S energy, especially when it comes to phase cancellations,
needs to use signed coefficients as input, yet it was using
abs'd coefficients. That was a slight bug.

AAC encoder: enforce SF delta in PNS and IS SFs · 60a76f8b

Claudio Freire authored Jan 16, 2016

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.

avcodec/v210: document the requirement for sample_factor · 4c430738

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]'
