+@ General notes:
+@
+@ Residual is generally only guaranteed to be clipped to 16 bits.
+@ This means that we do need to do vmovl, vqadd, vqmovun
+@ rather than vaddw, vqmovun (if we were clipped to 15 then we could get away
+@ with this).
+@
+@ There is an exception for the DC case because its transform is guaranteed
+@ to be small enough that overflow cannot occur during the first add.

+@ Assumptions:
+@ (that wouldn't apply to all frame layoouts but do apply to sand, so beware
+@ if reuseing this code)
+@
+@ Min ctb size is 8 so we don't need to worry about tr_size or dl_size for
+@ N==4, but do for chroma N>=8. As we share Y/C fns that means we can ignore
+@ N==8,PW=8 (chroma always PW>8) but have to cope for larger
+@
+@ We always have at least 64 pixel H frame width rounding - this lets us
+@ load UR widthout having to worry about exactly how many pixels are actually
+@ within the frame. As partial loads will only occur very occasionally this
+@ should be a win in nearly all cases.
+@
+@ 16 bit fns can be used as 8 bit chroma fns as chroma never filters
+@ so we do no maths on the contents
+@
+@ No filtering in 32bit fns as they are chroma only

+# Logic here should be good to 14 bits without modification
+# but only 8 & 10 are currently instantiated & tested
+# 15 & 16 bits have different shift1, shift2 calc & I also suspect overflow
+# in _p00 & _b00
+
+# The @ "mul_used", 0 annotations that occur by various mul blocks suppress
+# the warning that we are using rotation & ra/rb registers. r0..3 can be
+# rotated through all 16 elems ra regs can only be rotated through their
+# local 4. As it happens this is what is wanted here as we do not want the
+# constants from the other half of the calc.
+
+# Number limits in P/B calculation
+#
+# In order to avoid issues with mul24 being an unsigned 24->32 bit multiplier
+# we offset our intermediates s.t. they always end up +ve before the next
+# multiply (may be -ve whilst summing but that doesn't matter).
+#
+# Range calc for up to 14 bits (Y-B pred):
+#
+# denom: [0, 7]

+# off: [-(1 << (bits-1)), (1 << (bits-1)) - 1]
+#

+# This all looks good and is mostly bit depth independant - and as we manage

+# In s/w we are effectively limited to the min vertical read which is >= 4
+# so output FIFO is the limit.
+#
+# As the test for read-next is is the main part of the Luma loop (rather than
+# the preload FIFO part) we are limited to min_luma_height - 1
+# Min_luma_height is 4 so we can only have a preload of 3
+# Beware that min_chroma_height (and_width) is 2 so we can't do the same trick

+# HEVC VPU Transform
+#
+# Transform matrix can be thought of as
+# output row vector = input row vector * transMatrix2
+#
+# The even rows of the matrix are symmetric
+# The odd rows of the matrix are antisymmetric
+#
+# So only need to compute the first half of the results, then can compute the remainder with a butterfly
+#
+# EXAMPLE
+# (a b c d) (1 2 2 1)
+# (3 4 -4 -3)
+# (5 6 6 5)
+# (7 8 -8 -7)
+#
+# x=(a c)(1 2) = 1a+5c 2a+6c
+# (5 6)
+#
+# y=(b d)(3 4) = 3b+7d 4b+8d
+# (7 8)
+#
+# u=x+y = 1a+5c+3b+7d 2a+4b+6c+8d
+# v=x-y = 1a+5c-3b-7d 2a+6c-4b-8d
+#
+# Final results are (u , v[::-1])
+#
+#
+# For 32x1 input, load even rows into HX(0++,0), odd rows into HX(16++,0)
+# Apply the even matrix first and stop before rounding
+# Then apply the odd matrix in a full manner:
+#
+# First step is to compute partial products with the first input (16 cycles)
+# 1a 3b 5c 7d 16x1 input coefficients produce 16x16 output
+# 2a 4b 6c 8d
+# 2a -4b 6c -8d
+# 1a -3b 5c -7d
+#
+# Second step is to sum partial products into final position (8 cycles)
+# 1a+3b+5c+7d
+# 2a+4b+6c+8d
+# 2a-4b+6c-8d
+# 1a-3b+5c-7d
+#
+# Then can apply butterfly to combine even results and odd results + rounding to produce 16 rows of output at a time (need to save in transposed format)
+#
+# For 16x16 no butterfly is required and can store final results in original location (Could do 2 16x16s in parallel to make use of the trick - saves on the adds)
+#
+# For 8x8 we could compute two in parallel.
+#
+#
+
+# Columns are transformed first
+#
+# Store top left half of transMatrix2 in
+# Store bottom left half of transMatrix2 in HX(32,32)
+#
+# For 16x16
+# HX(0:15,0) contains input data before transform
+# HY(0:15,0) contains 32bit output data after transform
+# HX(32,0) contains even rows of left half of transMatrix2
+# HX(32,32) contains odd rows of left half of transMatrix2
+# HY(48,0) contains partial products ready for summing

+@ General notes:
+@ Having done some timing on this in sand8->y8 (Pi4)
+@ vst1 (680fps) is a bit faster than vstm (660fps)
+@ vldm (680fps) is noticably faster than vld1 (480fps)
+@ (or it might be that a mix is what is required)
+@
+@ At least on a Pi4 it is no more expensive to have a single auto-inc register
+@ for dest address than it is to have 2 used alternately (On Pi3 Ben asserted
+@ the latter was better)
+@
+@ vstm will bus error on unaligned access (so will vldm), vst1 is safe unless
+@ the memory is uncached.
+@ As these are Sand -> planar we can assume that src is going to be aligned but
+@ it is possible that dest isn't (converting to .yuv or other packed format).
+@ Luckily vst1 is faster than vstm :-) so all is well
+@ vst1 has alignment requirements of el size so maybe splitting vst1.32 into 4
+@ .8 stores would let us do non-word aligned stores into uncached but it
+@ probably isn't worth it.

+Building Pi FFmpeg
+==================
+
+Current only building on a Pi is supported.
+This builds ffmpeg the way I've tested it
+
+Get all dependencies - the current package dependencies are good enough
+
+$ sudo apt-get build-dep ffmpeg
+
+Configure using the pi-util/conf_native.sh script
+-------------------------------------------------
+
+This sets the normal release options and creates an ouutput dir to build into
+The directory name will depend on system and options but will be under out/
+
+There are a few choices here
+ --mmal build including the legacy mmal-based decoders and zero-copy code
+ this requires appropriate libraries which currently will exist for
+ armv7 but not arm64
+ --noshared
+ Build a static image rather than a shared library one. Static is
+ easier for testing as there is no need to worry about library
+ paths being confused and therefore running the wrong code, Shared
+ is what is needed, in most cases, when building for use by other
+ programs.
+
+So for a static build
+---------------------
+
+$ pi-util/conf_native.sh --noshared
+
+$ make -j8 -C out/<wherever the script said it was building to>
+
+You can now run ffmpeg directly from where it was built
+
+For a shared build
+------------------
+
+$ pi-util/conf_native.sh
+
+You will normally want an install target if shared. Note that the script has
+set this up to be generated in out/<builddir>/install, you don't have to worry
+about overwriting your system libs.
+
+$ make -j8 -C out/<builddir> install
+
+You can now set LD_LIBRARY_PATH appropriately and run ffmpeg from where it was
+built or install the image on the system - you have to be careful to get rid
+of all other ffmpeg libs or confusion may result. There is a little script
+that wipes all other versions - obviously use with care!
+
+$ sudo pi-util/clean_usr_libs.sh
+
+Then simply copying from the install to /usr works
+
+$ sudo cp -r out/<builddir>/install/* /usr
+

+Notes on the hevc_rpi decoder & associated support code
+-------------------------------------------------------
+
+There are 3 main parts to the existing code:
+
+1) The decoder - this is all in libavcodec as rpi_hevc*.
+
+2) A few filters to deal with Sand frames and a small patch to
+automatically select the sand->i420 converter when required.
+
+3) A kludge in ffmpeg.c to display the decoded video. This could & should
+be converted into a proper ffmpeg display module.
+
+
+Decoder
+-------
+
+The decoder is a modified version of the existing ffmpeg hevc decoder.
+Generally it is ~100% faster than the existing ffmpeg hevc s/w decoder.
+More complex bitstreams can be up to ~200% faster but particularly easy
+streams can cut its advantage down to ~50%. This means that a Pi3+ can
+display nearly all 8-bit 1080p30 streams and with some overclocking it can
+display most lower bitrate 10-bit 1080p30 streams - this latter case is
+not helped by the requirement to downsample to 8-bit before display on a
+Pi.
+
+It has had co-processor offload added for inter-pred and large block
+residual transform. Various parts have had optimized ARM NEON assembler
+added and the existing ARM asm sections have been profiled and
+re-optimized for A53. The main C code has been substantially reworked at
+its lower levels in an attempt to optimize it and minimize memory
+bandwidth. To some extent code paths that deal with frame types that it
+doesn't support have been pruned.
+
+It outputs frames in Broadcom Sand format. This is a somewhat annoying
+layout that doesn't fit into ffmpegs standard frame descriptions. It has
+vertical stripes of 128 horizontal pixels (64 in 10 bit forms) with Y for
+the stripe followed by interleaved U & V, that is then followed by the Y
+for the next stripe, etc. The final stripe is always padded to
+stripe-width. This is used in an attempt to help with cache locality and
+cut down on the number of dram bank switches. It is annoying to use for
+inter-pred with conventional processing but the way the Pi QPU (which is
+used for inter-pred) works means that it has negligible downsides here and
+the improved memory performance exceeds the overhead of the increased
+complexity in the rest of the code.
+
+Frames must be allocated out of GPU memory (as otherwise they can't be
+accessed by the co-processors). Utility functions (in rpi_zc.c) have been
+written to make this easier. As the frames are already in GPU memory they
+can be displayed by the Pi h/w without any further copying.
+
+
+Known non-features
+------------------
+
+Frame allocation should probably be done in some other way in order to fit
+into the standard framework better.
+
+Sand frames are currently declared as software frames, there is an
+argument that they should be hardware frames but they aren't really.
+
+There must be a better way of auto-selecting the hevc_rpi decoder over the
+normal s/w hevc decoder, but I became confused by the existing h/w
+acceleration framework and what I wanted to do didn't seem to fit in
+neatly.
+
+Display should be a proper device rather than a kludge in ffmpeg.c
