g on Windows and it looks like 'checkasm' performance
benchmarking is only enabled on Linux. For my tests I put a 100x loop around
the 'unpack_frame' call and ran:
ffmpeg.exe -s:v 1920x1080 -vcodec v210 -stream_loop 200 -i
OddaView_1920x1080.v210 -f null -y NUL

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.

Is there a FAQ or other documentation on how to submit patches? There's a
compiler warning that's driving me nuts and I'd like to clean it up if I

A later patch to configure to make sure it was defined, so the breakage
stopped. The patch for the configure option and the code should have been
atomic, IMNSHO.

Sadly, no.
double log = (fpclassify(val) == FP_ZERO ? av_int2double(UINT64_C(0xFFF) <<
52) : floor(log10(fabs(val;

Removing -ffast-math from my mplayer build appears to have resolved the
issue. Thank you for your time and guidance.
Per the message I get from ffmpeg/ffplay (likewise video players like
mpv that depend on ffmpeg), I get the following message on every frame
of an APNG file that I constructed:
