sorry, i am not clear what you say. Is that mean I only need to check
the fps of wmv files for the "ofps" option, for other file, e.g. mov
or 3gp, I can use a fixed "ofps"

if used -nosound, i can get the average fps, e.g
BENCHMARKs: VC: 1.954s VO: 0.000s A: 0.000s Sys: 0.062s = 2.016s
BENCHMARK%: VC: 96.9246% VO: 0.0000% A: 0.0000% Sys: 3.0754% = 100.0000%
Otherwise, i can get
BENCHMARKs: VC: 0.092s VO: 0.000s A: 0.032s Sys: 33.595s = 33.719s
BENCHMARK%: VC: 0.2728% VO: 0.0000% A: 0.0949% Sys: 99.6323% = 100.0000%
BENCHMARKn: disp: 502 (14.89 fps) drop: 3 (0%) total: 505 (14.98 fps)
i.e. 15 fps
