Hi,

I would like to know what is the best way to reduce the frame rate of SIPL camera’s output.
For example, the static frame rate of SF3325 camera is 30 fps, but i want to feed the down stream processes with 10 fps video to reduce resource utilization. One method I can come up with is discarding 2 frames in every 3 incoming frames in my ISP queue handlers of the SIPL camera.
Is there any better way to reduce fps? Is it possible to let ICP or ISP reduce the output frame rate?

Hi, @leqiang.wang

Yes, I think you can do it in nvsipl::INvSIPLClient::INvMCallback::OnFrameAvailable().
If I get a better suggestion from our team, I’ll update you here. Thanks.

Yes, implementing frame drop in OnFrameAvailable, or doing same thing in the finish queue handler in 5.2.6 is my current solution. Please let me know if there is more efficient solution. Thank for the reply.

The most efficient solution should be add a camera mode to support desire frame rate but it’s out of forum scope.
