  • cover some more options in fprofile. (esa, bime, cqm, nr, no-dct-decimate, trellis2)

  • fix a possible nondeterminism with me=umh + threads.



Veranderingen voor rev. 678 - rev. 680

  • regression in r669: broke saving of configure args if make has to re-run configure



Veranderingen voor rev. 669 - rev. 670

  • regression in r669: --enable-shared should imply --enable-pic on some archs.



Veranderingen voor rev. 667 - rev. 669

  • Update config.guess.
  • Add a --host flag to allow overriding config.guess; this is particularly useful with a 64-bits kernel running a 32-bits userland to build 32-bits apps.
  • Normalize any host triplet into a quadruplet via config.sub.
  • Move option parsing before any use of architecture information.



Veranderingen voor rev. 666 - rev. 667

  • allow compiling without yasm/nasm on x86 and x86-64 platforms



Veranderingen voor rev. 655 - rev. 656

  • replace alloca with malloc everywhere. per manpage, use of alloca is discouraged. this may have a minor effect on the speed of ssim and esa, but that appears too small to measure.



Veranderingen voor rev. 654 - rev. 655

  • require a ratecontrol method to be specified, it no longer defaults to cqp=26.



Veranderingen voor rev. 653 - rev. 654

  • fix nnz computation in cavlc+8x8dct+deblock. (regression in r607)



Veranderingen voor rev. 651 - rev. 652

  • c89 compile fix



Veranderingen voor rev. 650 - rev. 651

  • cabac: use bytestream instead of bitstream.
  • 35% faster cabac, 20% faster overall lossless, ~1% faster overall at normal bitrates.



Veranderingen voor rev. 649 - rev. 650

  • remove the restriction on number of threads as a function of resolution (it was wrong anyway in the presence of B-frames), and raise the max number of threads in general (though more will have to be done before it can really scale to lots of cores).



Veranderingen voor rev. 648 - rev. 649

  • tweak ssse3 quant



Veranderingen voor rev. 645 - rev. 648

  • workaround gcc's inability to align variables on the stack.
  • this crash was introduced in r642, but only because previous versions didn't use sse2 on the stack.
  • faster cabac rdo. up to 10% faster at q0, but negligible at normal bitrates.
  • change some tables from int to int8_t. 13KB smaller executable.



Veranderingen voor rev. 644 - rev. 645

  • 32bit version of ssse3 satd.
  • switch default assembler to yasm. it will still fallback to nasm if you don't have yasm.



Veranderingen voor rev. 639 - rev. 644

  • simplify trellis
  • fix an arithmetic overflow in trellis with QP >= 42
  • 2x faster quant. 2% overall.
  • side effects:
  • not bit-identical to the previous algorithm.
  • while the new algorithm covers a wider range of cqms than the previous one did,
  • I couldn't find a good way to fallback to a general version for the extreme
  • cqms. so now it refuses to encode extreme cqms instead of just being slower.
  • lays a framework for custom deadzone matrices, though I didn't add an api.
  • when encoding with a cqm, probe_skip now also uses the cqm, instead of the flat matrix
  • cosmetics in asm macros



Veranderingen voor rev. 638 - rev. 639

  • use only c-style comments in public header (patch by Vincent Torres)



Veranderingen voor rev. 636 - rev. 638

  • Compile fix

  • remove private stuff from public headers. no more need for -D__X264__



Veranderingen voor rev. 634 - rev. 635

  • adjust bitstream buffer sizes for very large frames



Veranderingen voor rev. 628 - rev. 634

  • conflate HAVE_MMXEXT with HAVE_SSE2, since they were never used distinctly.
  • Made -DNEED_ALTIVEC unnecessary, thanks to Guillaume Poirier.
  • check x264_cpu_detect() before calling AltiVec functions.
  • ssse3 detection. x86_64 ssse3 satd and quant.
  • requires yasm >= 0.6.0
  • Use -maltivec when building dependencies, or cannot be used.
  • Do not declare vectors in non-AltiVec files.
  • common/cpu.c: runtime AltiVec autodetection on Linux.
  • configure, Makefile: do not build the whole project with -maltivec because it generates AltiVec code in weird places.



Veranderingen voor rev. 627 - rev. 628

  • fix a small memleak.
  • patch by Limin Wang.



Veranderingen voor rev. 626 - rev. 627

  • compile fix for GCC-3.3 on OSX, based on a patch by
  • Patrice Bensoussan % patrice P bensoussan A free P fr%
  • Note: regression test still do not pass with GCC-3.3,
  • but they never did as far as I can remember.



Veranderingen voor rev. 623 - rev. 624

  • add ability to generate doxygen documentation; make dox



Veranderingen voor rev. 622 - rev. 623

  • oops, scenecut detection failed to activate when using threads and not using B-frames

  • extras/getopt.c was BSD licensed. replace with a LGPL version (from glibc).

  • Cleans up a few inconsistencies in the code too.

  • tweak block_residual_write_cavlc.
  • up to 1% faster lossless, no difference at normal bitrates.



Veranderingen voor rev. 618 - rev. 619

  • don't assume int is exactly 4 bytes



Veranderingen voor rev. 617 - rev. 618

  • make array_non_zero() compatible with -fstrict-aliasing



Veranderingen voor rev. 616 - rev. 617

  • Honor CFLAGS and LDFLAGS set by the user



Veranderingen voor rev. 615 - rev. 616

Veranderingen voor rev. 614 - full rev. 614

  • Check version of nasm on OS X / Intel



Veranderingen voor rev. 613 - rev. 614

  • Note: doesn't take advantage of some possible aligned memory accesses, so there's still room for improvement



Veranderingen voor rev. 600 - rev. 601

  • Merges Guillaume Poirier's AltiVec changes:
  • * Adds optimized quant and sub*dct8 routines
  • * Faster sub*dct routines
  • ~8% overall speed-up with default settings
