[MPlayer-dev-eng] The new vo_xover and some tdfx_vid benchmark

[Alban Bedel]

Hi,

As i got the overlay working in tdfx_vid i started to write a vo xtdfx. But the thing
turned in a more general approch. I added 3 new control and a new open flag.
The first control just check for support (it will be called before preinit).
The two others set the colorkey and overlay position. A flag is also added to
the config call so the "sub driver" now that it shouldn't use aspect, etc.
The code is 100% from vo_xvidix so we can perhaps get rid of it (to avoid
having 2 time the same code).
Now tdfx_vid is usable in x11 :)))) Sadly the x server isn't too kind and sometimes
it turn off the overlay :(
Some benchmark on my k6-2 333 :

./mplayer -vo xv ../samples/divx-bandits-sample.avi -nosound 
-benchmark -frames 1500
BENCHMARKs: VC:  32.198s VO:  19.401s A:   0.000s Sys:   2.374s =   53.973s
BENCHMARK%: VC: 59.6550% VO: 35.9462% A:  0.0000% Sys:  4.3988% = 100.0000%

./mplayer -vo xv ../samples/divx-bandits-sample.avi -nosound 
-benchmark -frames 1500 -dr -double
BENCHMARKs: VC:  31.258s VO:  13.504s A:   0.000s Sys:   3.912s =   48.673s

./mplayer -vo tdfxfb ../samples/divx-bandits-sample.avi -nosound

./mplayer -vo xover:tdfx_vid ../samples/divx-bandits-sample.avi

BENCHMARKs: VC:  31.253s VO:   2.288s A:   0.000s Sys:   3.237s =   36.779s
BENCHMARK%: VC: 84.9760% VO:  6.2220% A:  0.0000% Sys:  8.8020% = 100.0000%

XV IS SHIT !!!!! (but that not new ;)
