Thanks for the advice but I have tried config-interval=1 before asking here,
but it didn't change anything. Now I have also tried setting it to -1 but
this didn't help either. I have GStreamer Core Library version 1.16.0

As stated above, I tried this with h264parse. As I unterstand rtph264pay
corretly I changed (and reduced for testing) my sending command to the

gst-launch-1.0 idsueyesrc
config-file="C:\\stream_720p_24fps_AutoExp_AES114_RGB24H.ini" ! 
videoconvert ! queue ! x264enc tune=zerolatency ! rtph264pay
config-interval=-1 !  udpsink host= port=5200

With this sending command, receiving with MPV or VLC does not work anymore
("Failed to recognize file format."). Therfore I used Gstreamer for
receiving as well:

gst-launch-1.0 -v udpsrc port=5200 ! application/x-rtp ! rtph264depay !
avdec_h264 ! videoconvert ! autovideosink sync=false async=false

Starting the sender before the receiver works, but starting the receiver
first leaves me with the same strange gray/green image. In both cases the
verbose output is the same:
