      avfilter/formats: do not allow unknown layouts in ff_parse_channel_layout if nret is not set · 977fd884
      Marton Balint authored
      Current code returned the number of channels as channel layout in that case,
      and if nret is not set then unknown layouts are typically not supported.
      
      Also use the common parsing code. Use a temporary workaround to parse an
      unknown channel layout such as '13c', after a 1 year grace period only '13C'
      will work.

      avutil/channel_layout: add av_get_extended_channel_layout · c4618f84
      Marton Balint authored
      Return a channel layout and the number of channels based on the specified name.
      
      This function is similar to av_get_channel_layout(), but can also parse unknown
      channel layout specifications.
      
      Unknown channel layout specifications are a decimal number and a capital 'C'
      suffix, in order to not break compatibility with the lowercase 'c' suffix,
      which is used for a guessed channel layout with the specified number of
      channels.

      This is similar to the arm version, but due to the larger registers
      on aarch64, we can do 8 pixels at a time for all filter sizes.
      
      Examples of runtimes vs the 32 bit version, on a Cortex A53:

      This is significantly faster than the ARM version in almost
      all cases except for the mix2 functions.
      
      Based on START_TIMER/STOP_TIMER wrapping around a few individual
      functions, the speedup vs C code is around 2-3x.

      Compared to the arm version, on aarch64 we can keep the full 8x8
      transform in registers, and for 16x16 and 32x32, we can process
      it in slices of 4 pixels instead of 2.
      
      Examples of runtimes vs the 32 bit version, on a Cortex A53:
                                                      ARM  AArch64

      The larger transforms are significantly faster than the corresponding
      ARM versions.
      
      The speedup vs C code is smaller than in 32 bit mode, probably
      because the 64 bit intermediates in the C code can be expressed
      more efficiently in aarch64.

      This has mostly got the same differences to the 8 bit version as
      in the arm version. For the horizontal filters, we do 16 pixels
      in parallel as well. For the 8 pixel wide vertical filters, we can
      accumulate 4 rows before storing, just as in the 8 bit version.

      This is pretty much similar to the 8 bpp version, but in some senses
      simpler. All input pixels are 16 bits, and all intermediates also fit
      in 16 bits, so there's no lengthening/narrowing in the filter at all.
      
      For the full 16 pixel wide filter, we can only process 4 pixels at a time
      (using an implementation very much similar to the one for 8 bpp),
      but we can do 8 pixels at a time for the 4 and 8 pixel wide filters with
      a different implementation of the core filter.

      The speedup vs C code measured in checkasm is around 1.1-4x.
      These numbers are quite inconclusive though, since the checkasm test
      runs multiple filterings on top of each other, so later rounds might
      end up with different codepaths (different decisions on which filter
      to apply, based on input pixel differences).
      
      Based on START_TIMER/STOP_TIMER wrapping around a few individual
      functions, the speedup vs C code is around 2-4x.

      This is structured similarly to the 8 bit version. In the 8 bit
      version, the coefficients are 16 bits, and intermediates are 32 bits.
      
      Here, the coefficients are 32 bit. For the 4x4 transforms for 10 bit
      content, the intermediates also fit in 32 bits, but for all other
      transforms (4x4 for 12 bit content, and 8x8 and larger for both 10
      and 12 bit) the intermediates are 64 bit.
      
      For the existing 8 bit case, the 8x8 transform fit all coefficients in
      registers; for 10/12 bit, when the coefficients are 32 bit, the 8x8
      transform also has to be done in slices of 4 pixels (just as 16x16 and
      32x32 for 8 bit).
      
      The slice width also shrinks from 4 elements to 2 elements in parallel
      for the 16x16 and 32x32 cases.
      
      The 16 bit coefficients from idct_coeffs and similar tables also need
      to be lenghtened to 32 bit in order to be used in multiplication with
      vectors with 32 bit elements. This leads to the fixed coefficient
      vectors needing more space, leading to more cases where they have to
      be reloaded within the transform (in iadst16).
      
      This technically would need testing in checkasm for subpartitions
      in increments of 2, but that slows down normal checkasm runs
      excessively.

      arm: Add NEON optimizations for 10 and 12 bit vp9 MC · a4d4bad7
      Martin Storsjö authored
      This work is sponsored by, and copyright, Google.
      
      The plain pixel put/copy functions are used from the 8 bit version,
      for the double size (e.g. put16 uses ff_vp9_copy32_neon), and a new
      copy128 is added.
      
      Compared with the 8 bit version, the filters can no longer use the
      trick to accumulate in 16 bit with only saturation at the end, but now
      the accumulators need to be 32 bit. This avoids the need to keep track
      of which filter index is the largest though, reducing the size of the
      executable code for these filters.
      
      For the horizontal filters, we only do 4 or 8 pixels wide in parallel
      (while doing two rows at a time), since we don't have enough register
      space to filter 16 pixels wide.
      
      For the vertical filters, we still do 4 and 8 pixels in parallel just
      as in the 8 bit case, but we need to store the output after every 2
      rows instead of after every 4 rows.
      
      Examples of relative speedup compared to the C version, from checkasm:

      This treats the case of no slices like no frames which it basically is.
