netscape-flash works with mozilla-firefox-bin and any other 32-bit browser, |
9 |
it's also possible to make it work with 64-bit konqueror. You might also be |

interested in looking at net-www/gnash, still alpha quality but will |

hopefully become a fully fledged flash player with amd64 support. |

mplayer-bin will play all codecs that you normally need win32codecs for. Also |
14 |
if you're like many users and WMV3 videos are all you use win32codecs for, |
15 |
you might be interested to know that a VC-1 (WMV3) codec is a google summer |
16 |
of code project, so will hopefully be in a future version of ffmpeg soon. |

-march=athlon64 implies -msse2, all amd64 cpus have sse2 support. |
33 |
|
34 |
Also -ftracer is not in the safe cflags list, personally I would not use it |
35 |
but if you believe it benefits you then go ahead. |

AFAIK '-march=athlon-xp -msse2' is equivalent to '-march=athlon64' |

I would not bother with a full system rebuild, everything should be fine. |
