I've confirmed exactly this behavior on RPi cam v2 and ubuntu 14.04 on an i5 laptop w. 8g ram and ssd.

Reverting this commit seems to have drastically improved this behavior. https://github.com/bluerobotics/qgroundcontrol/commit/ce3cba6e5603471e81a9a2cdedcbe8460dad8255

This appears to be a problem with making every frame an I frame on the RPi camera. Removing the --intra 1 option from the raspivid command resolves the issue.
