how to control DM365 video frame rate?

Other Parts Discussed in Thread: TVP5150

Hi,Guys:

In dvsdk4.0, Encode and decode demos all runs at full frame rate: PAL@25fps.

If I need to play the video in 15 fps,or others , How to modify it? Should I just specify some parameter in encoder ,so decoder will play the low frame rate. Or I need to change params in encoder and decoder both ?

Any reply is appreciated!

What video source you use? if you use CMOS you can configure framerate on it.

Well, the video source is from a PAL analog camera (CVBS), we use a TVP5150 to get the PAL video.

I have googled and found some suggestion.

They suggested slow down the encode thread (videoThrFxn()). the only thing I can imagine is using usleep() function.

Is it precisely to control frame rate?

Any other suggestion else?
