The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things. Note that this is not exported; use lavu/mathematics for such purposes. Reviewed-by:

Until now, for formats which were in the spec but not in the encoder's list of supported formats required the -strict -1 flag. This enables support for all video formats which are specified, all the way from QSIF525 to 8K. Signed-off-by:

Adding early support for a subset of the proposed colour elements according to the latest version of spec: https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&index=hIKLhMdgTMTEwUTeA4ct38h0tmE Like matroskadec, I've left out elements for pix_fmt related things as there still seems to be some discussion around these. The new elements are exposed under strict experimental mode. Signed-off-by:

dv_frame_offset() is static and called only from dv_read_seek(), where c->sys->frame_size is already used. This simplifies the incoming codecpar merge where avctx->{coded_width,coded_height,time_base} are not accessible anymore.

This is ~2x faster for y not an integer on Haswell+GCC, and should generally be faster due to the fact that anyway powf essentially does this under the hood. Made an inline function in lavu/internal.h for this purpose. Note that there are some accuracy differences, that should generally be negligible. In particular, FATE still passes on this platform. Results in ~ 7% speedup in aac encoding with -march=native, Haswell+GCC. before: ffmpeg -i sin.flac -acodec aac -y sin_new.aac 6.05s user 0.06s system 104% cpu 5.821 total after: ffmpeg -i sin.flac -acodec aac -y sin_new.aac 5.67s user 0.03s system 105% cpu 5.416 total This is also faster than an alternative approach that pulls in powf, gets rid of the crufty NaN checks and other special cases, exploits knowledge about the intervals, etc. This of course does not exclude smarter approaches; just suggests that there would need to be significant work on this front of lower utility than searches for hotspots elsewhere.
