vaapioverlay with mjpeg decompression from Logitech Brio4K

Hi, I am using the following pipeline for mixing multiple USB camera feeds and I have a problem when using it with a Logitech Brio4K camera. gst-launch-1.0 v4l2src device=/dev/video2 ! image/jpeg,width=3840,height=2160! vaapijpegdec ! vaapioverlay ! fpsdisplaysink video-sink="vaapisink fullscreen=true" sync=false text-overlay=false -v The result is quite not in sync and seems to stop after a while. I am also getting low frame rate capture. If I remove the vaapioverlay plugin from pipeline, no problem at all. I am using iHD driver with Ubuntu 19.10 and also using gstreamer 1.1.7.
