Ronald S. Bultje a4edaa0270 vp9: add mxext versions of the single-block (w=8,npx=8) h/v loopfilters. 
Each takes about 0.1% of runtime in my profiles, and they didn't have
any SIMD yet so far (we only had simd for npx=16 double-block versions).

Ronald S. Bultje 726501a34e vp9: add 32x32 idct AVX2 implementation. 
About 1.8x speedup compared to AVX version for full IDCT. Other
sub-IDCT scenarios also see speedups. Full --bench output for
idct_32x32_add_{bpp}_${subidct}_${opt} (50k cycles):

Ronald S. Bultje 70d418c7e6 Revert "PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD." 
This reverts commit 1df908f33f. The expected
performance improvements are essentially non-existent.

Ronald S. Bultje f0a2b6249b vp9: add 16x16 idct avx2 (8-bit). 
checkasm --bench, 10k runs, for *_add_${bpc}_${sub_idct}_${opt}, shows
that it's about 1.65x as fast as the AVX version for the full IDCT, and
similar speedups for the sub-IDCTs:

Ronald S. Bultje 531ff7161d vf_colorspace: don't enable passthrough if bitdepth doesn't match. 
Also check return value of av_frame_copy() in passthrough mode, so that
if a copy fails (as it did here, because bitdepth didn't match), the filter
doesn't return success, which would mean sending an uninitialized framebuffer
further down the filtergraph.
 2016-05-10 09:26:17 -04:00
Ronald S. Bultje 356c116536 vf_colorspace: fix range order. 2016-05-10 09:26:17 -04:00
Ronald S. Bultje 9bbed8645a vf_colorspace: make whitepoint adaptation mode configurable. 
Also add von kries whitepoint adaptation, and add 'identity' to turn
whitepoint adaptation off.
 2016-05-10 09:26:16 -04:00
Ronald S. Bultje 3ed5218bd3 fate: add matroska-remux test. 
This tests automatic insertion of the vp9_superframe BSF as well as
ensuring that the colorspace properties in the video header can be
modified when remuxing (-c:v copy).
 2016-05-10 09:26:12 -04:00
Ronald S. Bultje 9c4943e671 ffmpeg: copy color properties in case of -c:v copy. 
I have no idea why the first hunk uses ost->enc_ctx, because as far as
I understand, that is never used in case of -c:v copy, but this code
block is only entered if encoding_needed=0, which means stream_copy=1.
My point being: review from someone that knows this really well would
be appreciated.
 2016-05-10 08:37:56 -04:00
Ronald S. Bultje f4075767b2 vf_colorspace: use enums for bpp/subsampling array indices.

Ronald S. Bultje 2e2e08a35b lavfi: new colorspace conversion filter. 
The intent here is similar to colormatrix, but it's LGPLv2.1-or-later
(instead of GPLv2.0) and supports gamma/chromaticity correction.

Ronald S. Bultje 98038e2ee0 swscale: fix bt709 yuv2rgb coefficients. 
They were derived from incorrect values cr=0.2125 (should be cr=0.2126)
and cb=0.0721 (should be cb=0.0722).

Ronald S. Bultje 6d8ab358a3 lavf: allow BSFs to drop packets. 
If pkt->size == 0 && pkt->side_data_elems == 0 after bsf->filter()
returns, the packet is considered dropped.

Ronald S. Bultje 0f88b3f82f videodsp: fix 1-byte overread in top/bottom READ_NUM_BYTES iterations. 
This can overread (either before start or beyond end) of the buffer in
Nx1 (i.e. height=1) images.

Ronald S. Bultje 20db54906f vp9_parser: allow superframes with a single frame. 2015-11-06 17:12:03 -05:00
Ronald S. Bultje c048303823 vp9: update timestamps in ref files using multiple invisible frames. 
For the 10-show-existing-frame, the source file indeed has a timestamp
of 3 (or 100/33) for the second visible frame, so the fix appears to
work correctly. For the other, only the timebase is fixed, but again
appears to be correct now.
 2015-10-29 07:55:12 -04:00
Ronald S. Bultje 63fca9df9c vp9_parser: don't overwrite cached timestamps with nopts. 2015-10-28 22:15:36 -04:00

Ronald S. Bultje 81d7f118e2 vf_psnr: remove %0.2f format specifiers for stream summary line. 
This makes output equally precise as vf_ssim.

Ronald S. BultjeandHendrik Leppkes b95f241b6e vp9: split header into separate struct and expose in vp9.h 
This allows hwaccels to access the bitstream header information.
 2015-10-15 13:02:20 +02:00
Ronald S. Bultje e578638382 vp9: use registers for constant loading where possible. 2015-10-13 11:06:01 -04:00
Ronald S. Bultje 408bb8556f vp9: refactor itx coefficients and share between 8 and 10/12bpp. 2015-10-13 11:06:01 -04:00
Ronald S. Bultje eb4b5ff738 vp9: add itxfm_add eob shortcuts to 10/12bpp functions. 
These aren't quite as helpful as the ones in 8bpp, since over there,
we can use pmulhrsw, but here the coefficients have too many bits to
be able to take advantage of pmulhrsw. However, we can still skip
cols for which all coefs are 0, and instead just zero the input data
for the row itx. This helps a few % on overall decoding speed.

Ronald S. Bultje 488fadebbc vp9: add 10/12bpp idct_idct_32x32 sse2 SIMD version. 2015-10-13 11:06:00 -04:00
Ronald S. Bultje 3d0ca2fe89 vp9: 10/12bpp sse2 SIMD for iadst16. 2015-10-13 11:06:00 -04:00

Ronald S. Bultje 235e76aeb8 vp9: initial attempt at a idct_idct_4x4 12bpp x86 simd (sse2) impl. 
The trouble with this function is that intermediates overflow 31+sign
bits, so I've added some helpers (that will also be used in 10/12bpp
8x8, 16x16 and 32x32) to make that easier, basically emulating a half-
assed pmaddqd using 2xpmaddwd. It's currently sse2-only, if anyone sees
potential in adding ssse3, I'd love to hear it.
 2015-10-13 11:05:58 -04:00
Ronald S. Bultje f76423d097 vp9: add x86 simd (sse2/ssse3) for iadst4 10bpp functions. 2015-10-13 11:05:58 -04:00

Ronald S. Bultje 1c3be32533 vp9: add 10/12bpp mmxext-optimized iwht_iwht_4x4 function. 2015-10-13 11:05:57 -04:00
Ronald S. Bultje 93866c2aa2 intmath: remove av_ctz. 
It's a non-installed header and only used in one place (flacenc).
Since ff_ctz is static inline, it's fine to use that instead.

Ronald S. Bultje ce78729033 vp9: don't keep a stack pointer if we don't need it. 
This saves one register in a few cases on 32bit builds with unaligned
stack (e.g. MSVC), making the code slightly easier to maintain.

(Can someone please test this on 32bit+msvc and confirm make fate-vp9
and tests/checkasm/checkasm still work after this patch?)

Ronald S. Bultje 350e9c6765 vp9: fix loopfilter test code to address Hendrik's comments.

 2015-09-21 20:44:14 -04:00
Ronald S. Bultje b074367405 checkasm: add VP9 loopfilter tests. 
The randomize_buffer() implementation assures that "most of the time",
we'll do a good mix of wide16/wide8/hev/regular/no filters for complete
code coverage. However, this is not mathematically assured because that
would make the code either much more complex, or much less random.

Ronald S. Bultje a0d8a81075 vp9: switch min_tile_cols location so it shifts up instead of down. 
This fixes cases where the shifted number is 64, but we shifted non-

with libvpx.

Ronald S. Bultje fd8b90f5f6 vp9: fix overflow in 8x8 topleft 32x32 idct ssse3 version. 
Also disable the mmx/iwht optimization when the bitexact flag is set.
With synthetically coded coefficients (i.e. these that lead to a
residual well outside the [-255,255] range), our optimizations will
overflow. It doesn't make sense to fix the overflows, since they can
only occur on synthetic input, not on real fwht-generated input. Thus,
add a bitexact flag that disables this optimization.

Ronald S. Bultje 9cdeb105a6 vp9: do unscaled MC in scaled path if size of this reference matches. 
This can happen if we do bidirectional MC, where one reference has the
same size as the current frame, but the other one doesn't.

Ronald S. Bultje 873dbc6758 vp9: sync segmentation.absolute_vals between threads. 2015-09-05 15:50:00 -04:00
Ronald S. Bultje 3d7173b509 vp9: always sync segmentation.feat between threads. 2015-09-05 15:50:00 -04:00
Ronald S. Bultje 9ee2ddd773 vp9_parse: fix parsing of pskip and profile 2/3. 
The fate results change because we now correctly timestamp the pskip
frames, which means the results are now identical to -vsync 0.

Ronald S. Bultje 10142f994a libvpxdec: explicitly signal RGB. 2015-09-04 09:33:46 -04:00
Ronald S. Bultje 4ecb8b4191 vp9: don't erase values for {lf,ref,skip,q}_enabled if segmentation=0. 
Instead, use segmentation.enabled before accessing each of these values.

Ronald S. Bultje 339550e7c8 vp9: reset segmentation information on context reset. 2015-09-04 09:33:43 -04:00
Ronald S. Bultje 7e12a54251 ffserver: use -b instead of -ab for setting audio bitrate. 2015-08-28 14:59:58 -04:00
Ronald S. Bultje 2fb593dcb9 Put remaining pieces of CODEC_FLAG_EMU_EDGE under FF_API_EMU_EDGE. 
The amv one probably looks suspicious, but since it's an intra-only
codec, I couldn't possibly imagine what it would use the edge for,
and the vsynth fate result doesn't change, so it's probably OK.
 2015-08-28 14:40:59 -04:00
Ronald S. Bultje 99b9f0136c fate: rename -error option to -error_rate. 
This fixes fate when FF_API_ERROR_RATE=0.
