Bug 86767 – media-video/mplayer-1.0_pre6-r1 does not utilize multimedia extensions on AMD64

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Sebastian Bergmann (RETIRED) 2005-03-26 05:20:43 UTC]

Although it is build with support for the multimedia extensions of the AMD64 platform

  # mplayer now contains SIMD assembler code for amd64
  # AMD64 Team decided to hardenable SIMD assembler for all users
  # Danny van Dyk <[e-mail]> 2005/01/11
  if use amd64; then
    myconf="${myconf} --enable-3dnow --enable-3dnowex --enable-sse --enable-mmx --enable-mmx2"
  fi

mplayer does not use these extensions at runtime

Can you try replacing sse with sse2?

[Comment 2 Sebastian Bergmann (RETIRED) 2005-03-27 12:59:13 UTC]

I changed the

  myconf="${myconf} --enable-3dnow --enable-3dnowex --enable-sse --enable-mmx --enable-mmx2"

line to

  myconf="${myconf} --enable-3dnow --enable-3dnowex --enable-sse2 --enable-mmx --enable-mmx2"

and rebuilt. Same result.

[Comment 3 Łukasz Mierzwa 2005-03-29 23:35:51 UTC]

This is probably fixed in cvs versions of mplayer, I'm using cvs version with:
--enable-3dnow --enable-3dnowex --enable-sse --enable-mmx --enable-mmx2 --enable-sse2
and I get no warnings about sse/sse2 or errors during playback.

This really seems to be fixed UPSTREAM:

Created attachment 55553 [details, diff]
patch from mplayer's cvs that disables sse & sse2 checks on x86_64

this patch is taken from mplayer cvs and it disables sse and sse2 chceck's on
x86_64 arch. please apply it to 1.0_pre6 ebuild and also please add
--enable-sse2 to myconf in ebuild.

[Comment 6 Simon Stelling (RETIRED) 2005-04-21 02:49:22 UTC]

that patch didn't do it for me:

MPlayer 1.0pre6-3.4.3-20050110 (C) 2000-2004 MPlayer Team
CPU: Advanced Micro Devices Opteron Sledgehammer (Family: 8, Stepping: 1)
Detected cache-line size is 64 bytes

Warning unknown option cache_min at line 144
Warning unknown option cache_prefill at line 147

77 audio & 189 video codecs

although we have all the --enable-blah stuff in myconf

i think best would be to wait for the next (pre)release where this is defintifely fixed.

meanwhile i did a little clean up so that we don't have lines like --disable-mmx --enable-mmx
