IP camera based on Logitech webcam, Beaglebone/Raspberry Pi and gstreamer.

Update Raspberry Firmware First

The capture util can also be run under Raspberry Pi, but you should be sure to update the firmware to the latest. Follow the instruction here: http://wiki.matthiasbock.net/index.php/Logitech_C920,_streaming_H.264#Raspberry_Pi

How to use the capture util

Under Windows

Run gstreamer in a remote machine, I use Windows as a client to view the video stream Install all the components of gstreamer-1.0 run the gst-launch from the bin directory of gstreamer, or you can set your environment PATH to gstreamers bin directory.

cd D:\gstreamer\1.0\x86_64\bin
D:\gstreamer\1.0\x86_64\bin>gst-launch-1.0 -e -v udpsrc port=8001 ! application/x-rtp, payload=96 ! rtpjitterbuffer ! rtph264depay ! avdec_h264 ! autovideosink sync=false

Under Ubuntu

Under Ubuntu, should be using the similar commandline as windows. (Not tested yet)

Under Raspberry Pi

When using in Raspberry Pi

./capture -c 10000 -o | gst-launch-1.0 -v -e filesrc location=/dev/fd/0 ! h264parse ! rtph264pay ! udpsink host=192.168.1.42 port=8001

After running the above command, you should be able to see the video in the remote machine, the result is better than using the vlc

Alternative method, but have delay==

Using VLC

While using vlc in Raspbery Pi:

cvlc v4l2:///dev/video0:chroma=h264:width=1080:height=720 --sout '#standard{access=http,mux=ts,dst=0.0.0.0:8080,name=stream,mime=video/ts}' -vvv

Run in client side (PC), the ip and port is your Raspberry Pi's ip address and port

gst-launch-1.0 playbin uri=http://192.168.1.163:8080

Using V4L2 with gstreamer

Using v4l2 in Raspberry Pi wil have the following error message:

pi@raspberrypi ~ $ gst-launch-1.0 -e -vvvvv v4l2src ! video/x-h264, width=1920, height=1080, framerate=30/1 ! h264parse ! rtph264pay pt=96 config-interval=30 ! udpsink host=192.168.1.42 port=8001
