I did this some years ago and successfully streamed at 720p/25ips in H.264. The streaming was done using RTSP and VLS as client.

Here are the notes I took at that time :

INSTALL Gstreamer

sudo apt-get install gstreamer1.0-plugins-bad gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-tools libgstreamer1.0-dev libgstreamer1.0-0-dbg libgstreamer1.0-0 gstreamer1.0-omx-rpi gstreamer1.0-omx-rpi-dbg libgstreamer-plugins-base1.0-dev gtk-doc-tools

INSTALL Camera driver

sudo apt-get install git
git clone github.com/.../gst-rpicamsrc.git
cd gst-rpicamsrc
./autogen.sh
make
sudo make install
gst-inspect-1.0 |grep rpicamsrc (to test that the camera works)

INSTALL RTSP Server

git clone git://anongit.freedesktop.org/gstreamer/gst-rtsp-server
gst-launch-1.0 --version
git checkout 1.10 (according to previous line)
./autogen.sh
make
sudo make install

TEST

~/gst-rtsp-server/examples/test-launch "( rpicamsrc preview=false bitrate=2000000 keyframe-interval=15 ! video/x-h264, framerate=15/1 ! h264parse ! rtph264pay name=pay0 pt=96 )"

(server listens to rtsp://rtsppicamera:8554/test)

CONFIG Automatic startup

sudo nano /etc/systemd/system/RTSPpiCamera.service

sudo systemctl start RTSPpiCamera.service

An update on this blog post. I noticed on the Raspberry Pi Camera documentation side a disclaimer about some of the commands.

It seems the problems I experienced using some of the commands are not unique.

"I will assume since the board is new, the software doesn’t fully support the hardware, resulting in the picture. The hardware identified doesn't exist and has no model number."

Not sure it will make a difference but you can pass pinout the revision code of the board rather than relying on autodetection.

Looks like 902120 is the revision code for the Zero 2 W

so pinout -r 902120 may or may not do something interesting...

"CRAP!" made me smile . I have a well worn path on CRAP road. Looking forward to the final ride on the Pi Zero Express
