How to solve the problem of RTSP fetching delay

[(15N12U30) 活动中心]

         How to solve the problem of a few seconds delay in fetching IP camera video data by gstreamer through rtsp? The instructions I used are as follows. Can I use the gst-launch tool to set the video buffer delay size to solve this problem?

         gst-launch-1.0 -v rtspsrc location=rtsp://admin:cx123456@192.168.60.64 ! rtph264depay ! queue max-size-time=0 ! vpudec ! imxvideoconvert_g2d ! video/x-raw, format=RGB16, width=1024, height=600 ! waylandsink
