Giorgio Vazzana	d0a34aeedf	md5: optimize second round by using 4-operation form of G() 4-operation form is preferred over 3-operation because it breaks a long dependency chain, thus allowing a superscalar processor to execute more operations in parallel. The idea was taken from: http://www.zorinaq.com/papers/md5-amd64.html AMD Athlon(tm) II X3 450 Processor, x86_64 $ for i in $(seq 1 4); do ./avutil_md5_test2; done size: 1048576 runs: 1024 time: 5.821 +- 0.019 size: 1048576 runs: 1024 time: 5.822 +- 0.019 size: 1048576 runs: 1024 time: 5.841 +- 0.018 size: 1048576 runs: 1024 time: 5.821 +- 0.018 $ for i in $(seq 1 4); do ./avutil_md5_test2; done size: 1048576 runs: 1024 time: 5.646 +- 0.019 size: 1048576 runs: 1024 time: 5.646 +- 0.018 size: 1048576 runs: 1024 time: 5.642 +- 0.019 size: 1048576 runs: 1024 time: 5.641 +- 0.019 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Janne Grunau	4b79668154	mpegvideo: unref old current_picture before allocating a new one Allows decoding with only three frame buffers with frame reference counting. Fixes VAAPI based decoding in vlc which uses only three frame buffers for the mpegvideo-based codecs.	12 years ago
Luca Barbato	db347280eb	vorbis: fallback to normal division instead of crashing The use of ff_inverse speeds up slightly arches + compilers that do not provide a division faster than the whole machinery, such as ppc32 + gcc4.7, but has operational limits. Drop the always-enable assert and provide a fallback.	12 years ago

Martin Storsjö	0b6899f154	configure: msvc: Set the target windows version to XP if no target is set MSVC 2010 (or more precisely, Windows SDK 7.0 which comes with MSVC 2010) sets _WIN32_WINNT to the constant for Windows 7 if nothing is set. This could lead to the libav configure script detecting and using functions only present in Windows 7 or newer, which in most cases isn't desired. If the caller explicitly wants this, the caller can add the _WIN32_WINNT define via --extra-cflags, setting the desired version. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
