9d8533368f Use memcpy() instead of a for loop in mdct512(). 
8% faster in function.

e8d21fba3f Allocate planar_samples using av_mallocz(). 
Lowers memory usage when encoding less than 6 channels.

171bc51c9b Allocate bap and bap1 buffers using av_malloc(). 
This reduces the memory footprint when using less than 6 channels.
Modify bit allocation to swap the 2 buffers instead of using memcpy() and use
per-block pointers for bap. This is slightly faster (0.3%) in function
cbr_bit_allocation().

1c3e117e0b Remove last_samples[] and copy directly from planar_samples[]. 
Avoids memcpy that was used to store last samples for next frame.
Approx. 3% faster in function deinterleave_input_samples() and reduces memory
usage by 3kB.

they can enable threading for all codecs by default.

cfff297d98 adpcm: Skip samples whose ssd calculation has wrapped around 
Wraparound in ssd is mainly avoided by subtracting the ssd of the
best node from all the others once it has grown large enough.

If using very large trellis sizes (e.g. -trellis 15), the frontier
is so large that the difference between the best and the worst is
large enough to cause wraparound, even if the ssd of the best one
is subtracted regularly.

When using -trellis 10 on a 30 second sample, this causes only a slight
slowdown, from 61 to 64 seconds.

Prior to this fix 87 out of 128 64kbit/s mono files decoded with ffmpeg
have
lower PEAQ ODG values than the same files decoded with libvorbis. With
this
fix none of that set have significantly worse ODG values than libvorbis.

d56920e206 aacenc: Correct spreading calculation for high spreading. 
The 3GPP spec uses the following calculation for high spreading:

thr'_spr = max(thr_scaled, s_h(n) * thr_scaled(n-1))

where, n is defined as the current band, and s_h() is defined as "[...] the
distance of adjacent bands in Bark and a constant slope that is 15 dB/Bark
[...]". This is a little ambiguous as you would assume you want the Bark
width of the previous band for this calculation. However, this assumption
appears to be incorrect, and you really want the Bark width of the current
band. Coincidentally this is exactly what the spec calls for! =P

This noticeably improves Tom's Diner at low bitrates (I tested at 64kbps,
with mid/side disabled).

c8dcb9dee1 aacenc: Remove energy 'normalization' modification from the 3GPP psymodel 
This greatly improves bitrate handling. You will now get within a few
kbps of your requested bitrate instead of 20-40kbps higher.

There is absolutely no analog to this line in the 3GPP spec, that I
can find.

4df5aebb81 aacenc: Fix threshold-in-quiet calculation in the 3GPP psymodel. 
Removing the modification vastly improves quality (at a slight bitrate
cost) for some samples. castanets.wav is a good example. The closest
equivalent I see to the modification in the 3GPP spec is a similar
modification (over a specific frequency range) when TNS is used.

This also changes the threshold-in-quiet calculation to match the
3GPP spec.

eafadadaf5 aacenc: Fix the conditions under which 3GPP pre-echo control is run. 
According to the 3GPP spec:
"Thus the pre-echo control is inactive for the first short window (but
not all short windows in a short frame) after a start block and for
all frames with a stop window sequence."

Currently, pre-echo control is only run when the current frame is not
a short frame, and the previous frame is not a short frame.

fc068f9f27 Fixed DXVA_Slice_H264_Long::BitOffsetToSliceData value. 
The 8 bits offset (nal unit type) should not be added, as the spec says:

"This bit offset is the offset within the RBSP data for the slice, relative
to the starting position of the slice_header() in the RBSP"

This fixes DXVA2 support for intel GPU.

Patch by Rafaël Carré (funman _AT_ videolan _DOT_ org).
