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


ID_FILENAME=d:\Temp\2.wmv
ID_DEMUXER=asf
ID_VIDEO_FORMAT=WMV2
ID_VIDEO_BITRATE=0
ID_VIDEO_WIDTH=320
ID_VIDEO_HEIGHT=240
ID_VIDEO_FPS=1000.000
ID_VIDEO_ASPECT=0.0000
ID_AUDIO_CODEC=ffwmav2
ID_AUDIO_FORMAT=353
ID_AUDIO_BITRATE=64032
ID_AUDIO_RATE=48000
ID_AUDIO_NCH=2
ID_LENGTH=37.00

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

Thanks.
