1 분 소요

thermal image streaming solution.

we need below package.

HW : respberrypi4, seekthermal J2 or J3 module.

SW : raspberrypi side

seekthermal sdk : https://github.com/younlea/TIC-thermal-imaging-camera
v4l2loopback : https://github.com/umlaeute/v4l2loopback
ffmpeg : https://ffmpeg.org/
gstreamer : https://gstreamer.freedesktop.org/
vlc : https://www.videolan.org/index.ko.html

windows side

vlc player : https://www.videolan.org/index.ko.html

raspberrypi seeting.

download seekthermal sdk

$git clone https://github.com/younlea/TIC-thermal-imaging-camera.git

please check the step on the git page. you can install seekthermal sdk and fine sample source code.

download v4l2loopback package and build (sudo apt-get install linux-headers)

$git clone https://github.com/umlaeute/v4l2loopback.git

$cd v4l2loopbakc

$make

$sudo make install

$sudo depmod -a

$sudo modprobe v4l2loopback video_nr=4

$ls /dev/video4

Now you can test v4l2loopback/example/test « If this app is correctly working, Now you are ready for next step.

launch stream application

build TIC-thermal-imaging-camera/example/seek-stream

$sudo ./seek-stream

Now we can use streaming node the node(/dev/video4).

let go next step.

you can choice encoder and streaming solution( ffmpeg, gstreamer, vlc)

case of gstreamer

install gstreamer.

apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-pulseaudio

you can see streming on raspberrypi (In this case, does not dealy via two capture images)

$gst-launch-1.0 v4l2src device=/dev/video4 ! video/x-raw, width=320, height=240 ! autovideosink

case of using gstreamer (currently not ok)

Now try streaming to ip (192.168.1.64)

$gst-launch-1.0 v4l2src device=/dev/video4 ! video/x-raw, width=320, height=240 ! videoconvert ! jpegenc ! rtpjpegpay ! udpsink host=192.168.1.64 port=5000

on my mac

$gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=JPEG,payload=26 ! rtpjpegdepay ! jpegdec ! autovideosink

mmmh.. gstreamer have one issue.

case of ffmpeg
