If MPEG PS misdetects a file, i would first try to fix the mpeg ps
probe to not misdetect it and produce a lower score for whatever
makes this file not mpeg-ps.

But i have not seen the file so this is just the general direction
i would look into ...

thx

If a bugfix only changes things apparently unrelated to the bug with no
further explanation, that is a good sign that the bugfix is wrong.

Re: [FFmpeg-devel] [PATCH] libavcodec Adding ff_v210_planar_unpack AVX2

2019-03-16 Thread Mike Stoner 
Hello,
I resent my AVX2 patch for v210 unpacking.  My first attempt didn't get picked 
up by the Patchwork list for some reason.

I installed Linux on a Broadwell laptop to utilize James Darnley's checkasm 
patch for v210 decode.  The results are below.  

AVX2 gets a nice boost from replacing SHUFPS instructions with VPBLENDD, which 
has more flexible port bindings.  VBLENDPS could also be substituted and is 
available from SSE4.1 onward, however I found only the AVX2 code received any 
measureable gain from that change.

Any further comments are greatly appreciated.  

Thanks,
Mike


Tested on Broadwell CPU, Ubuntu 18.10 x86_64

[FFmpeg-devel] [PATCH 5/5] aarch64/opusdsp: implement NEON accerelated postfilter and deemphasis

2019-03-16 Thread Lynne 
153372 UNITS in postfilter_c,   65536 runs,  0 skips
73164 UNITS in postfilter_neon,   65536 runs,  0 skips -> 2.1x speedup

80591 UNITS in deemphasis_c,  131072 runs,  0 skips
43969 UNITS in deemphasis_neon,  131072 runs,  0 skips -> 1.83x speedup

Total decoder speedup: ~15% on a Raspberry Pi 3 (from 28.1x to 33.5x realtime)

Deemphasis SIMD based on the following unrolling:
const float c1 = CELT_EMPH_COEFF, c2 = c1*c1, c3 = c2*c1, c4 = c3*c1;
float state = coeff;

for (int i = 0; i < len; i += 4) {
    y[0] = x[0] + c1*state;
    y[1] = x[1] + c2*state + c1*x[0];
    y[2] = x[2] + c3*state + c1*x[1] + c2*x[0];
    y[3] = x[3] + c4*state + c1*x[2] + c2*x[1] + c3*x[0];

    state = y[3];
    y += 4;
    x += 4;
}

Unlike the x86 version, duplication is used instead of pslldq so
the structure and tables are different.
Same approach tested on x86 (3x pslldq -> vbroadcastss + shufps + pslldq)
had the same performance, so 3x pslldq was kept as vbroadcastss has a higher
latency.

[FFmpeg-devel] avcodec/proresenc (aw and ks) : use correct bitstream version in frame header

2019-03-16 Thread Martin Vignali 
Hello

Patch in attach change bitstream version in prores frame header
(based on RDD36)
0 for 422
1 for 444 with ou without alpha

001 : Fix for prores_aw (update 444 fate test)
002 : Fix for prores_ks (no fate update because 444 is not tested for ks
encoder)

Pass fate for me (x86_64 macos)
