additional tests:

server: gst-rtsp
server pipeline: rtspsrc location=... ! rtph264depay byte-stream=false !
h264parse ! rtph264pay name=pay0 pt=96
client: gstreamer on windows
client pipeline: rtspsrc location=urltogstrtsp ! rtph264depay ! ffdec_h264 !
...
result: crash after about 30 minutes 
notes: tryed serveral options for rtp264depay and with and without the
h264parse element the crash remain

server: gst-http
server pipeline: rtspsrc location=... ! rtph264depay byte-stream=false !
h264parse ! gdppay ! appsink
client: gstreamer on windows (neonhttpsrc ... ! gdpdepay ! ...)
result: stable for hours

server: gst-rtsp
server pipeline: rtspsrc location=... ! rtpmp4vdepay ! mpeg4videoparse !
rtph264pay name=pay0 pt=96
client: gstreamer on windows
client pipeline: rtspsrc location=urltogstrtsp ! rtpmp4vdepay ! ffdec_mpeg4 !
...
result: gst-launch doesn't crash but I have frequently this error:

the video is green until the next keyframe, this happen frequently (in the log
above 3 times in 7 seconds)

notes: tryed with and without mpeg4videoparse (both on server and on client),
no changes


server: gst-http
server pipeline: rtspsrc location=... ! rtpmp4vdepay ! mpeg4videoparse ! gdppay
! appsink
client: gstreamer on windows (neonhttpsrc ... ! gdpdepay ! ...)
result: stable for hours with no keyframe issue

minor issue observed in all cases:

- h264 stream:

the effect is visible on the video but is not observed frequently,

please note that vlc on windows works fine both with gst-rtsp than directly
connected to the cameras
