[Libav-user] How to increase frame rate in ffmpeg?

[김희숙]

Hello,
 
I'm wondering how to increase frame rate in FFMpeg.
I added some trace in vfwcap.c and I calculated frame rate.
I found out vfwcap driver can capture 15 frame per second but ffmpeg sends 30 at fps if I set up -r 30 option.
 
How can control frame rate in FFMpeg?
 
I'll appriciate any feedback.
 
Best Regards,
HSK
