Subject: [PATCH 01/94] h264_parser: Initialize the h264dsp context in the
 parser as well
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each AVStream struct for an H.264 elementary stream actually has two
copies of the H264DSPContext struct (and in fact all the other members
of H264Context as well):

((H264Context *) ((AVStream *)st)->codec->priv_data)->h264dsp
((H264Context *) ((AVStream *)st)->parser->priv_data)->h264dsp

but only the first of these was actually being initialised. This
prevented the addition of platform-specific implementations of
parser-related functions.

Subject: [PATCH 02/94] h264dsp: Factorize code into a new function,
 h264_find_start_code_candidate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This performs the start code search which was previously part of
h264_find_frame_end() - the most CPU intensive part of the function.

By itself, this results in a performance regression:
              Before          After
              Mean   StdDev   Mean   StdDev  Change
Overall time  2925.6 26.2     3068.5 31.7    -4.7%

but this can more than be made up for by platform-optimised
implementations of the function.

+Subject: [PATCH 1/3] h264_parser: Initialize the h264dsp context in the
+ parser as well
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Each AVStream struct for an H.264 elementary stream actually has two
+copies of the H264DSPContext struct (and in fact all the other members
+of H264Context as well):
+
+((H264Context *) ((AVStream *)st)->codec->priv_data)->h264dsp
+((H264Context *) ((AVStream *)st)->parser->priv_data)->h264dsp
+
+but only the first of these was actually being initialised. This
+prevented the addition of platform-specific implementations of
+parser-related functions.

+Subject: [PATCH 2/3] h264dsp: Factorize code into a new function,
+ h264_find_start_code_candidate
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This performs the start code search which was previously part of
+h264_find_frame_end() - the most CPU intensive part of the function.
+
+By itself, this results in a performance regression:
+              Before          After
+              Mean   StdDev   Mean   StdDev  Change
+Overall time  2925.6 26.2     3068.5 31.7    -4.7%
+
+but this can more than be made up for by platform-optimised
+implementations of the function.

From db098a580259625bb7b7385a48cb0756aea5cafe Mon Sep 17 00:00:00 2001
From: Ben Avison <bavison@riscosopen.org>
Date: Wed, 16 Apr 2014 01:51:31 +0100
Subject: [PATCH 05/94] h264: Move search code search functions into separate
 source files.

This permits re-use with parsers for codecs which use similar start codes.

Subject: [PATCH 06/94] vc-1: Add platform-specific start code search routine
 to VC1DSPContext.

Initialise VC1DSPContext for parser as well as for decoder.
Note, the VC-1 code doesn't actually use the function pointer yet.

From 9b459c3c4130299099b2e5aca5bff3d6f8d60e72 Mon Sep 17 00:00:00 2001
From: Ben Avison <bavison@riscosopen.org>
Date: Wed, 23 Apr 2014 01:41:04 +0100
Subject: [PATCH 07/94] vc-1: Optimise parser (with special attention to ARM)

The previous implementation of the parser made four passes over each input
buffer (reduced to two if the container format already guaranteed the input
buffer corresponded to frames, such as with MKV). But these buffers are
often 200K in size, certainly enough to flush the data out of L1 cache, and
for many CPUs, all the way out to main memory. The passes were:

1) locate frame boundaries (not needed for MKV etc)
2) copy the data into a contiguous block (not needed for MKV etc)
3) locate the start codes within each frame
4) unescape the data between start codes

After this, the unescaped data was parsed to extract certain header fields,
but because the unescape operation was so large, this was usually also
effectively operating on uncached memory. Most of the unescaped data was
simply thrown away and never processed further. Only step 2 - because it
used memcpy - was using prefetch, making things even worse.

This patch reorganises these steps so that, aside from the copying, the
operations are performed in parallel, maximising cache utilisation. No more
than the worst-case number of bytes needed for header parsing is unescaped.
Most of the data is, in practice, only read in order to search for a start
code, for which optimised implementations already existed in the H264 codec
(notably the ARM version uses prefetch, so we end up doing both remaining
passes at maximum speed). For MKV files, we know when we've found the last
start code of interest in a given frame, so we are able to avoid doing even
that one remaining pass for most of the buffer.

In some use-cases (such as the Raspberry Pi) video decode is handled by the
GPU, but the entire elementary stream is still fed through the parser to
pick out certain elements of the header which are necessary to manage the
decode process. As you might expect, in these cases, the performance of the
parser is significant.

To measure parser performance, I used the same VC-1 elementary stream in
either an MPEG-2 transport stream or a MKV file, and fed it through ffmpeg
with -c:v copy -c:a copy -f null. These are the gperftools counts for
those streams, both filtered to only include vc1_parse() and its callees,
and unfiltered (to include the whole binary). Lower numbers are better:

                Before          After
File  Filtered  Mean   StdDev   Mean   StdDev  Confidence  Change
M2TS  No        861.7  8.2      650.5  8.1     100.0%      +32.5%
MKV   No        868.9  7.4      731.7  9.0     100.0%      +18.8%
M2TS  Yes       250.0  11.2     27.2   3.4     100.0%      +817.9%
MKV   Yes       149.0  12.8     1.7    0.8     100.0%      +8526.3%

Yes, that last case shows vc1_parse() running 86 times faster! The M2TS
case does show a larger absolute improvement though, since it was worse
to begin with.

This patch has been tested with the FATE suite (albeit on x86 for speed).

From c2ebe54fe1d7c7a6cee7282bcf2668a826006ade Mon Sep 17 00:00:00 2001
From: Ben Avison <bavison@riscosopen.org>
Date: Wed, 19 Mar 2014 17:44:59 +0000
Subject: [PATCH 08/94]  truehd: add hand-scheduled ARM asm version of
 mlp_filter_channel.

Profiling results for overall audio decode and the mlp_filter_channel(_arm)
function in particular are as follows:

              Before          After
              Mean   StdDev   Mean   StdDev  Confidence  Change
6:2 total     380.4  22.0     370.8  17.0    87.4%       +2.6%  (insignificant)
6:2 function  60.7   7.2      36.6   8.1     100.0%      +65.8%
8:2 total     357.0  17.5     343.2  19.0    97.8%       +4.0%  (insignificant)
8:2 function  60.3   8.8      37.3   3.8     100.0%      +61.8%
6:6 total     717.2  23.2     658.4  15.7    100.0%      +8.9%
6:6 function  140.4  12.9     81.5   9.2     100.0%      +72.4%
8:8 total     981.9  16.2     896.2  24.5    100.0%      +9.6%
8:8 function  193.4  15.0     103.3  11.5    100.0%      +87.2%

Experiments with adding preload instructions to this function yielded no
useful benefit, so these have not been included.

The assembly version has also been tested with a fuzz tester to ensure that
any combinations of inputs not exercised by my available test streams still
generate mathematically identical results to the C version.

Subject: [PATCH 09/94] truehd: break out part of rematrix_channels into
 platform-specific callback.

Verified with profiling that this doesn't have a measurable effect upon
overall performance.

Subject: [PATCH 10/94] truehd: add hand-scheduled ARM asm version of
 ff_mlp_rematrix_channel.

Profiling results for overall audio decode and the rematrix_channels function
in particular are as follows:

              Before          After
              Mean   StdDev   Mean   StdDev  Confidence  Change
6:2 total     370.8  17.0     348.8  20.1    99.9%       +6.3%
6:2 function  46.4   8.4      45.8   6.6     18.0%       +1.2%  (insignificant)
8:2 total     343.2  19.0     339.1  15.4    54.7%       +1.2%  (insignificant)
8:2 function  38.9   3.9      40.2   6.9     52.4%       -3.2%  (insignificant)
6:6 total     658.4  15.7     604.6  20.8    100.0%      +8.9%
6:6 function  109.0  8.7      59.5   5.4     100.0%      +83.3%
8:8 total     896.2  24.5     766.4  17.6    100.0%      +16.9%
8:8 function  223.4  12.8     93.8   5.0     100.0%      +138.3%

The assembly version has also been tested with a fuzz tester to ensure that
any combinations of inputs not exercised by my available test streams still
generate mathematically identical results to the C version.

Subject: [PATCH 11/94] truehd: tune VLC decoding for ARM.

Profiling on a Raspberry Pi revealed the best performance to correspond
with VLC_BITS = 5. Results for overall audio decode and the get_vlc2 function
in particular are as follows:

From bdefac00779c5601816f949353d9bbeb3b199611 Mon Sep 17 00:00:00 2001

Subject: [PATCH 13/94] truehd: add hand-scheduled ARM asm version of
 ff_mlp_pack_output.

Profiling results for overall decode and the output_data function in
particular are as follows:

              Before          After
              Mean   StdDev   Mean   StdDev  Confidence  Change
6:2 total     339.6  15.1     329.3  16.0    95.8%       +3.1%  (insignificant)
6:2 function  24.6   6.0      9.9    3.1     100.0%      +148.5%
8:2 total     324.5  15.5     323.6  14.3    15.2%       +0.3%  (insignificant)
8:2 function  20.4   3.9      9.9    3.4     100.0%      +104.7%
6:6 total     572.8  20.6     539.9  24.2    100.0%      +6.1%
6:6 function  54.5   5.6      16.0   3.8     100.0%      +240.9%
8:8 total     741.5  21.2     702.5  18.5    100.0%      +5.6%
8:8 function  63.9   7.6      18.4   4.8     100.0%      +247.3%

The assembly version has also been tested with a fuzz tester to ensure that
any combinations of inputs not exercised by my available test streams still
generate mathematically identical results to the C version.

Subject: [PATCH 14/94] More efficient infobool expression evaluator

Expession infobools are evaluated at runtime from one or more single infobools
and a combination of boolean NOT, AND and OR operators. Previously, parsing
produced a vector of operands (leaf nodes) and operators in postfix
(reverse-Polish) form, and evaluated all leaf nodes every time the expression
was evaluated. But this ignores the fact that in many cases, once one operand
of an AND or OR operation has been evaluated, there is no need to evaluate the
other operand because its value can have no effect on the ultimate result. It
is also worth noting that AND and OR operations are associative, meaning they
can be rearranged at runtime to better suit the selected skin.

This patch rewrites the expression parsing and evaluation code. Now the
internal repreentation is in the form of a tree where leaf nodes represent a
single infobool, and branch nodes represent either an AND or an OR operation
on two or more child nodes.

Expressions are rewritten at parse time into a form which favours the
formation of groups of associative nodes. These groups are then reordered at
evaluation time such that nodes whose value renders the evaluation of the
remainder of the group unnecessary tend to be evaluated first (these are
true nodes for OR subexpressions, or false nodes for AND subexpressions).
The end effect is to minimise the number of leaf nodes that need to be
evaluated in order to determine the value of the expression. The runtime
adaptability has the advantage of not being customised for any particular skin.

The modifications to the expression at parse time fall into two groups:
1) Moving logical NOTs so that they are only applied to leaf nodes.
   For example, rewriting ![A+B]|C as !A|!B|C allows reordering such that
   any of the three leaves can be evaluated first.
2) Combining adjacent AND or OR operations such that each path from the root
   to a leaf encounters a strictly alternating pattern of AND and OR
   operations. So [A|B]|[C|D+[[E|F]|G] becomes A|B|C|[D+[E|F|G]].

I measured the effect while the Videos window of the default skin was open
(but idle) on a Raspberry Pi, and this reduced the CPU usage by 2.8% from
41.9% to 39.1%:

Subject: [PATCH 16/94] Add caching of infolabels

The functions CGUIInfoLabel::GetLabel and CGUIInfoLabel::GetItemLabel take
a number of strings returned from CGUIInfoManager::GetImage or
CGUIInfoManager::GetLabel, and combine them with various constant strings
which were determined during CGUIInfoLabel::Parse.

Rather than perform all the string operations on every call, this patch
changes to use a two-pass process: first it queries all the GetImage/GetLabel
strings, and then only if at least one of them has changed does it bother
rebuilding the resultant string - otherwise it re-uses the copy built on a
preceding call.

CGUIInfoLabel::GetLabel/GetItemLabel are also changed to return string
references, rather than forcing an additional string copy.

I have measured the effect while the Videos window of the default skin was
open (but idle) on a Raspberry Pi, and this reduced the CPU usage by 0.8%
from 36.2% to 35.4%:

          Before          After
          Mean   StdDev   Mean   StdDev  Confidence  Change
IdleCPU%  36.2   0.5      35.4   0.5     99.9%       +2.2%

Subject: [PATCH 18/94] Faster and simpler portable implementation of
 MathUtils::round_int().

Much as I like a bit of inline assembler, I have also removed the ARM versions
of MathUtils::truncate_int() and MathUtils::round_int(). The former was just
how any sane compiler should have assembled a cast from double to signed int
anyway. The latter was a much too complicated way to achieve the desired
effect, and was switched out in most ARM builds anyway in favour of the old
portable implementation that used floor().

Verified that MathUtils::test() still passes, and that GCC is now able to
inline MathUtils::round_int(), where it didn't previously.

I tested on a Raspberry Pi with the default theme, displaying the front page
with the RSS ticker enabled. This saturates the CPU, so I'm measuring the
improvement using the debug window's FPS figure. This patch improves this from
~50.8 FPS to ~52.6 FPS.

+    /* This implementation warrants some further explanation.
+     *
+     * First, a couple of notes on rounding:
+     * 1) C casts from float/double to integer round towards zero.
+     * 2) Float/double additions are rounded according to the normal rules,
+     *    in other words: on some architectures, it's fixed at compile-time,
+     *    and on others it can be set using fesetround()). The following
+     *    analysis assumes round-to-nearest with ties rounding to even. This
+     *    is a fairly sensible choice, and is the default with ARM VFP.
+     *
+     * What this function wants is round-to-nearest with ties rounding to
+     * +infinity. This isn't an IEEE rounding mode, even if we could guarantee
+     * that all architectures supported fesetround(), which they don't. Instead,
+     * this adds an offset of 2147483648.5 (= 0x80000000.8p0), then casts to
+     * an unsigned int (crucially, all possible inputs are now in a range where
+     * round to zero acts the same as round to -infinity) and then subtracts
+     * 0x80000000 in the integer domain. The 0.5 component of the offset
+     * converts what is effectively a round down into a round to nearest, with
+     * ties rounding up, as desired.
+     *
+     * There is a catch, that because there is a double rounding, there is a
+     * small region where the input falls just *below* a tie, where the addition
+     * of the offset causes a round *up* to an exact integer, due to the finite
+     * level of precision available in floating point. You need to be aware of
+     * this when calling this function, although at present it is not believed
+     * that XBMC ever attempts to round numbers in this window.
+     *
+     * It is worth proving the size of the affected window. Recall that double
+     * precision employs a mantissa of 52 bits.
+     * 1) For all inputs -0.5 <= x <= INT_MAX
+     *    Once the offset is applied, the most significant binary digit in the
+     *    floating-point representation is +2^31.
+     *    At this magnitude, the smallest step representable in double precision
+     *    is 2^31 / 2^52 = 0.000000476837158203125
+     *    So the size of the range which is rounded up due to the addition is
+     *    half the size of this step, or 0.0000002384185791015625
+     *
+     * 2) For all inputs INT_MIN/2 < x < -0.5
+     *    Once the offset is applied, the most significant binary digit in the
+     *    floating-point representation is +2^30.
+     *    At this magnitude, the smallest step representable in double precision
+     *    is 2^30 / 2^52 = 0.0000002384185791015625
+     *    So the size of the range which is rounded up due to the addition is
+     *    half the size of this step, or 0.00000011920928955078125
+     *
+     * 3) For all inputs INT_MIN <= x <= INT_MIN/2
+     *    The representation once the offset is applied has equal or greater
+     *    precision than the input, so the addition does not cause rounding.

From 427373ae5bb96489afb22529714c16e8f82c2195 Mon Sep 17 00:00:00 2001

Subject: [PATCH 20/94] Convert CGUIFontTTFBase::m_vertex to be managed as a
 std::vector. Also retired CGUIFontTTFBase::m_vertex_count and
 CGUIFontTTFBase::m_vertex_size because these can be derived from vector
 member functions.

Subject: [PATCH 22/94] Add a cache of font glyph bounding box vertices. This
 is implemented as a template because ultimately we will key on different
 parameters and store values of different types, depending upon whether we
 have a GLES or non-GLES backend, and for GLES, whether or not the currently
 applicable transformation matrices permit the use of hardware clipping.

Subject: [PATCH 23/94] Lay the groundwork for hardware clipping.

For glScissor() to replace CGraphicContext::ClipRect, a necessary condition
is that no shear or rotation is introduced between the coordinate systems
they use; this depends upon the settings of the GUI matrix m_finalTransform
as well as the OpenGL model-view and projection matrices. These all remain
unchanged between paired calls of CGUIShader::OnEnabled and
CGUIShader::OnDisabled, so we scan the matrices in CGUIShader::OnEnabled to
see whether hardware clipping is possible.

Then, in CGUIFontTTFBase::RenderCharacter, we don't apply software clipping
in such cases. However, because vertices arising from multiple
CGUIFontTTFBase::DrawTextInternal calls (each of which often uses a different
clip rectangle) get lumped into the same vector, which only at the end is
passed to OpenGL for rendering, we need to wait a few commits before we can
actually apply hardware clipping. In the meantime, expect to see rendering
errors.

Subject: [PATCH 24/94] Increase font cache hit rate by keying on the
 fractional part of m_originX and m_originY *after* they have been through the
 graphics context's transformation matrix, plus the scale/rotation elements of
 the matrix, rather than the origin in the original frame of reference plus
 the complete transformation matrix. All vertices of individual glyph bounding
 boxes are a constant offset from this position, and when the fractional part
 of the translation is a match, the rounding of each vertex will be in the
 same direction; this permits us to calculate the desired vertices from the
 cached ones simply by adding the integer parts of the translations with no
 additional rounding steps.

Note that this requires that software clipping is *not* performed.

From 10eeb73ca15798de26abd5f8846214c8938f8b42 Mon Sep 17 00:00:00 2001
From: Ben Avison <bavison@riscosopen.org>
Date: Wed, 8 Jan 2014 12:16:33 +0000
Subject: [PATCH 25/94] Rewrite of scrolling text code.

No longer shuffles the string round to minimise the number of characters
before the clipping rectangle; this doesn't save much on rendering time but
does harm the effectiveness of the cache. Now uses a pixel offset into the
string rather than a character + pixel offset, and plots the entire string
every time (execpt when the wrap point is visible, in which case the entire
string is plotted twice).

It also makes motion smoother, because (possibly unintentionally) the
previous code preferred to align the scroll offset with character boundaries.
This would lead to uneven changes of position, especially when the width of
the character currently being scrolled off the edge was only slightly more
than an integral multiple of the scroll increment.

Subject: [PATCH 26/94] Move the application of the translation offsets into
 the GLES code. Still all pure software at this stage. Main change is in the
 data types at the interface between CGUIFontTTFBase and CGUIFontTTFGL. The
 old way (array of vertices in m_vertex) are retained in addition, for the
 sake`of cases that need to use software clipping on GLES, as well as for DX
 and GL support where the new scheme is not (yet?) used.

Subject: [PATCH 27/94] Rather than applying the translation offsets to the
 vertices, now applies them to the model view matrix from the top of the
 matrix stack and pushes it over to OpenGL. The vertices themselves are still
 all held client-side.

Subject: [PATCH 35/94] Fix header to hopefully permit iOS builds to work
 again. GUIShader.cpp added #include windowing/egl/WinSystemEGL.h inside a but
 also need the header windowing/osx/WinSystemIOS.h instead. The only thing
 GUIShader.cpp needed was g_windowing.GetViewPort, which is provided by the
 common base class CRenderSystemGLES of g_windowing in both cases, so I think
 it should be sufficient to use windowing/WindowingFactory.h instead, which is
 abstracted away from the other header files.

Subject: [PATCH 36/94] Fix font display in stereoscopic modes
 CGUIFontTTFGL::LastEnd was previously using the relatively high-level
 CGraphicContext::SetScissors function to enforce hardware clipping. However,
 the coordinates it passed in already contained the stereoscopic offset, so
 the CGraphicContext::SetScissors effectively ended up double-applying the
 offset, with the effect that clip rectangles were always off-screen. Changed
 to call the low-level SetScissors call instead (using g_Windowing to select
 the correct implementation, e.g. CRenderSystemGLES::SetScissors). This also
 skips the intersection of the scissors with the screen limits, but that does
 not appear to matter in practice.

Using dvdplayer can be useful on the Pi. We can actually play sd (up to 640x480 MPEG-4 video) video in real time.
This is useful for codec variants like DivX3 which we don't currently play.

This may expose bugs where dvdplayer is incorrectly used as the default player which will need to be fixed

Subject: [PATCH 49/94] Improved file buffering in CArchive.

CArchive already did some file buffering, but only on writes. Added the
equivalent code for reads. Also improved the write buffer case so that it
only ever issues sector-aligned writes (the read code does this from the
start). Shuffled various bits of code into the header file to squeeze a bit
more performance out of it.

Profiled the effect on CFileItemList::Archive(), which is one of the slow
parts of the process of reopening a media library, on a non-overclocked
Raspberry Pi. Times are in seconds:

Subject: [PATCH 52/94] [omxplayer] Allow small audio packets to be
 concatenated to make better use of audio fifo

Some audio codecs produce small packets which causes a high overhead when submitting to GPU, and doesn't make full use of GPU side buffering.
TrueHD in particular can produce packets with 40 samples (so 1200 packets per second) which causes very high overhead.

What this aims to do is to concatenate audio packets until they approach the ideal audio packet size,
and then deal with the awkardness of concatenated planar formats.

Subject: [PATCH 54/94] [omx] Skip the resize when not needed when decoding
 jpegs

The decode to texture path almost always uses cached jpegs that are the correct size, so the resize is rarely needed.
The re-enc path usually needs resizing, but may not where the source is small.

Skipping the resize stage saves a little time and memory on GPU and also saves some setup time.

Subject: [PATCH 57/94] [omxplayer] Make use of TrueHD fastpath when downmixing

The TrueHD codec actually works in 3 stages. It decodes the downmixed stereo. It then decodes the differences required to produce 5.1.
It then decodes the differences required to produce 7.1.

Many users end up downmixing this 7.1 stream back to 2.0.
Much better to tell the codec we only need the 2.0 stream. It saves about 50% of the CPU required

Subject: [PATCH 61/94] [ffmpeg] Speed up wtv index creation

The index creation is O(N^2) with number of entries (typically thousands).
On a Pi this can take more than 60 seconds to execute for a recording of a few hours.

By replacing with an O(N) loop, this takes virtually zero time

Subject: [PATCH 71/94] [omxplayer] Support stereo view modes with scaling

The Pi only supported a single view rectangle, which is sufficient for all mono view modes,
but only supports a subset of stereo modes.

To work around this, the scaling rectangles were ignored in 3D modes and 3D video was treated as unscaled.
While this worked or square pixel, 16:9 content on a 16:9 display, it went wrong is various other conditions.

@sraue reported that mono view of SBS/TAB content wasn't scaled correctly, and other forum reports
aspect ratio errors in widescreen 3D videos.

As it wasn't trivial to work around these bug reports, I've added a new stereo flags to the firmware
that allows a second display region to be created for the second eye, allowing scaling to work.

I've been through the video stereo modes (none, sbs, tab) and the display stereo modes (mono, sbs, tab)
and all the zoom modes, and compared the scaling to xbmc on windows and all seem to match

Requires udpated firmware.

Include matching 3D flags (SBS/TAB) in the score of a resolution to switch to, to enable switching to 3d modes.
Also remove the old code that treated 3D modes differently when assigning a score.

Subject: [PATCH 88/94] Reset display region when video stream properties
 change

Currently when video stream properties change, e.g. when user switches to next or previous Live TV channel, and has the same frame width and height, the COMXVideo::SetVideoRect() method is not called, causing the video to play back with default source and destination rectangles, not respecting the user-defined zoom settings.

This commit fixes the issue.

Subject: [PATCH 94/94] [rbp] Reduce GPU memory use when limited

Switching from default triple buffered output to double buffered saves 8M with 1080p GUI.
This may slightly reduce framerate, but is likely to be minimal.

Assume if gpu_mem is set below the default 128M that this memory reduction is wanted
