just received Raspberry pi 4B - 4 GB model.

I have tested below command for recording and streaming parallelly from
Raspberry pi camera using Gstreamer pipeline.

sudo  gst-launch-1.0  -v v4l2src device=/dev/video0 do-timestamp=true ! tee
name=tee ! capsfilter
caps="video/x-raw,width=1920,height=1080,framerate=30/1,bitrate=40000" !
queue ! videoflip method=rotate-180 ! videoconvert  ! videorate ! queue !
omxh264enc ! queue ! avimux ! queue ! filesink location = test.h264
qos=true --gst-debug=GST_QOS:5 ! queue ! videoscale method=1 ! videoconvert
! capsfilter caps="video/x-raw,width=256,height=144,framerate=30/1" !
queue  ! videoflip method = rotate-180 ! queue ! omxh264enc  ! queue !
h264parse ! mpegtsmux ! rtpmp2tpay ! multiudpsink
clients= ttl=1

After running this same command at 480p30fps and 720p30fps they
working fine but same command at 1080p 30fps  frame skipping problem and
also in video bottom line appeared as green.

so please suggest me when 1080p at 30 fps not working.
Any reason??
