Problem with recording video and displaying at the same time

[Zyx]

Hi,

I am receiving a video from udp port. I wanted to save it in a file and at
the same time display it on the screen. When I do this separately it works
just fine:

gst-launch-1.0 -e -v udpsrc port=5000 ! application/x-rtp, payload=96 !
rtpjitterbuffer ! rtph264depay ! h264parse ! omxh264dec ! ximagesink
sync=false

and for recording:
gst-launch-1.0 -e -v udpsrc port=5000 ! application/x-rtp, payload=96 !
rtpjitterbuffer ! rtph264depay ! h264parse ! matroskamux ! filesink
sync=false location='/home/pi/recorded/test.mkv'

But when I do this using one command like this:
gst-launch-1.0 -e -v udpsrc port=5000 ! application/x-rtp, payload=96 !
rtpjitterbuffer ! rtph264depay ! h264parse ! tee name=t ! queue matroskamux
! filesink sync=false location='/home/pi/recorded/test.mkv' t. ! queue !
omxh264dec ! ximagesink sync=false

I've got internal data flow error:

Does anyone have an idea what is wrong?
