I had time today to test the gstreamer rtsp server on my 3W.
The test here re-used an old Rock 3A rootfs i tuned some time ago, so i can say it is fully compatible with rk3568, the missing bit is the NPU.

2. Minimum requirements
Kernel, RGA, MPP, gstreamer, and rockchip media must be up-to-date.

3. Building gstreamer rtsp server
Build:
wget https://gstreamer.freedesktop.org/src/gst-rtsp-server/gst-rtsp-server-1.20.3.tar.xz
tar -xf gst-rtsp-server-1.20.3.tar.xz gst-rtsp-server-1.20.3/
cd gst-rtsp-server-1.20.3/
mkdir build && cd build
meson --prefix=/usr --wrap-mode=nofallback -D buildtype=release -D package-origin=https://gstreamer.freedesktop.org/src/gstreamer/ -D package-name=“GStreamer 1.20.3” …
ninja -j4
sudo ninja install
sudo ldconfig
Run:
cd examples/
rock@rzero-3w:~/rockchip/gstreamer/rtsp-server/gst-rtsp-server-1.20.3/build/examples$
sudo ./test-launch “( v4l2src device=/dev/video0 io-mode=dmabuf ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 ! mpph264enc ! rtph264pay name=pay0 pt=96 )”
