This patch replaces the transform used in AAC with lavu/tx and removes
the limitation on only being able to decode 960-sample files
with the float decoder.
This commit also removes a whole bunch of unnecessary and slow
lifting steps the decoder did to compensate for the poor accuracy
of the old

should i make another release of 5.0 ?
should i move 5.0 to olddownloads ?

thx

Set the correct amount of tags in tags_per_config[] and ensure the side
channels (Surround in the spec) are used.

Add arm64 neon implementations for hscale 16 to 15 with filter
sizes 4, 8 and X4.
The tests and benchmarks run on AWS Graviton 2 instances.
The results from a checkasm tool are shown below.
hscale_16_to_15__fs_4_dstW_512_c: 6703.5
hscale_16_to_15__fs_4_dstW_512_neon: 2298.0
Add arm64 neon implementations for hscale 8 to 19 with filter
sizes 4, 4X and 8. Both implementations are based on very similar ones
dedicated to hscale 8 to 15. The major changes refer to saving
the data - instead of writing the result as int16_t it is done
with int32_t.
These functions are
This patchset contains arm64 neon implementation of hscale functions.
Fixed minor style issues and declared C function wrappers as static.
This patchset do not contain the patch for checkasm tool, as the
previous one did. The reason behind it was failing tests on x86 arch
but not on aarch64 or
Provide arm64 neon optimized implementations for hscale16To19 with
filter sizes 4, 8 and X4.
The tests and benchmarks run on AWS Graviton 2 instances.
The results from a checkasm tool are shown below.
hscale_16_to_19__fs_4_dstW_512_c: 6216.0
hscale_16_to_19__fs_4_dstW_512_neon: 2257.0
These tables are only accessed in ff_set_qscale()
which only accesses values 1..31 as well as in
encode_picture() in mpegvideo_enc.c, accessing
the value with index 8. So make these tables smaller.

This e.g. allows compilers to bake the offset implied
by using ff_mpeg12_dc_scale_table[3] (as the SpeedHQ encoder
does) into the general offset; for certain arches this is
also necessary in order to avoid building suboptimal code.
