The Raspberry Pi camera module supports 1080p30, 720p60, and VGA90 video modes as well as still captures. The autovideosink opens a window showing the streamed data.Figure 1: Raspberry Pi Camera Module v2 (Image Credit: ) This gstreamer command will read the the data from the the IP and PORT where we were serving the data. We need to run the following command on PC to see the stream in a window after filling in the Rpi IP address and port gst-launch-1.0 -v tcpclientsrc host= port= ! gdpdepay ! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink sync=false Next is the gstreamer pipeline is reading from the piped input and serving the stream over tcp. If '-' is specified the output will go to stdout.
Putting a 0 here will mean the camera preview will run indefinitely.
'-t' represents the time the program waits before capturing image and shutdown. The raspivid is used to capture video from the camera. raspivid -t 0 -o - | gst-launch-1.0 fdsrc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! tcpserversink host= port= Once the camera is detected we can run the following command after putting our Rpi IP address and the port. We can check the camera detection using the command mentioned above. If camera is not detected we should try adjusting the cable. Often it happens that cable at camera module end or Rpi end is not connected properly. If it is detected, an image is captured and stored by the name followed by '-o' switch. This command will capture the image from the camera. Post the reboot, we can check if the camera is detected and working fine using the following command: raspistill -o image.jpg I had used an ssh connection, Rpi can be logged in via Interface too if we have a TV/monitor/other display with a mini HDMI cable. We should put the flex cable in the module and slowly push the collar. The camera module has a collar (black color) which needs to be pulled slowly. # gstreamer : A multimedia framework (runs on both Windows and Linux) # PC (Tested on both Windows 10 OS and Ubuntu 18.04) # Raspberry Pi Zero W fit with SD Card and Raspberry Pi OS installed on it This streaming is the first step to my little adventure. Since I am working on a Computer Vision Platform so I thought to try out building a CCTV setup for home. I started browsing about hats and accessories related to Rpi and found a 5 MP camera which was cheap enough (under Rs. I was looking around some projects but couldn't settle on any idea. Recently I got a Raspberry Pi Zero W as a Secret Santa gift.
