Gstreamer Appsrc Buffer

This post was updated on .
Hi, I am working on streaming webcam video from Raspberry Pi to Mac.

I will be using OpenCV on OSX end to retrieve Gstreamer video as frame and do some processing.

I am wondering that if OpenCV does not grab in time, where the transfered video stream will be stored?

Say that I could only grab one frame each 50ms, which is 20 fps, but the video is 30 fps.

Will the remaining 10 fps just be discarded?

If it is stored, how much memory space or disk space does it cost to store a 1280x720 30fps video from
