Bug 57459 – MPlayer MMX USE flag missing

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description ferreira.hugo 2004-07-18 01:41:19 UTC]

I "emerged mplayer" (ver 1.0_pre4) and saw that the MMX and SSE extentions 
were not being used. An "emerge -pv mplayer" shows only the SSE flag. 
Activating these options via 'USE="mmx sse", emerge -pv mplayer' once again is 
only reflected in the SSE extention. The mmx USE flag should be shown.

Reproducible: Always
Steps to Reproduce:
1.emerge -pv mplayer
2.We can see that the USE flag is "-sse", no "mmx" is shown
3.USE="mmx sse", emerge -pv mplayer'
4.We can see that the USE flag is "sse", no "mmx" is shown
Actual Results:  
After setting USE="mmx sse" mplayer compiled correctly and
executing mplayer -v shows that MMX and SSE are active. 

Expected Results:  
I think this is just a case of incorrect output from "emerge info mplayer"
because an errenuous entry in the e-build files (wharever these are;-))

Mine.  I'm cleaning up the ebuild right now and I may have fixed the ebuild.  I'm drafting it right now for approval, so it should be out soon.

i'm having problems with mplayer now (1.0_pre5-r2), because +mmx sets both mmx and mmx2 optimizations in mplayer. my processor doesn't support mmx2, and it cannot be turned off with useflags.

[Comment 3 Chris White (RETIRED) 2004-08-17 23:27:09 UTC]

MPlayer's mmx logic is changed.

mmx2 and sse2 USE flags have now been added to accomidate avaliabilty
to users that can handle it.

Check pre5-r3 for this.
