OnVideoSourceEncodedSample of WindowsVideoEndPoint is not called periodically #8

The video sampling from OnVideoSourceEncodedSample is jerky. as FrameArrivedHandler is not called at fixed intervals(the event is not raised for a long time. and all of a sudden, it is called a few times). This is a silly question that probably is non-relevant to SIPSorceryMedia.Windows project. I am new to video programming, is it caused by intensive cpu usage?

Yes, more likely CPU related although if you're using FFmpeg or libvpx native libraries for encoding it should cope fine.

A good test would be to reduce the frame rate and/or resolution and see if the problem persists. If it goes away then that does point to a CPU bottleneck.
