Using Gstreamer, take a h264 stream from a Logitech c920, preview it on the display and save it to a file along with the webcam audio.
# Preview and save webcam video on NVIDIA Jetson TK1
# Grab audio and video (in h264 format) from Logitech c920 @ 1920x1080
# Preview @ 1280x720 on screen
# Store video to file named gEncode1080p.mp4
# Logitech c920 is video1 on this machine
VELEM="v4l2src device=/dev/video1 do-timestamp=true"
# Video capability from the camera - get h264 1920x1080

Install Grinch Linux4Tegra (L4T) version 19.3.6 for NVIDIA Jetson TK1

For this process you will need:

  • A host desktop or laptop computer running Ubuntu Linux 12.04. This may be a VM, I've used VirtualBox.
  • Micro USB cable provided with the Jetson TK1 kit
  • Jetson TK1 and power supply
  • Optional: DB9 null modem cable if you want to use the serial console during boot
  1. On your host computer open a Terminal, then create a directory to operate from, and switch to it. As an example:
mkdir ~/Grinch
cd ~/Grinch

Gstreamer two MJPG Webcams
# Run two video webcam feeds in two different windows
# Script assumes that:
# Microsoft LifeCam Studio is video0
# Logitech c920 is video1
# Both cameras run max 1920x1080 MJPG, but two have both on a USB bus they can run @ 1280x720 max
# MS is made a little smaller
# text overlay and clockoverlay may be added to the pipeline, but render poorly
