HDMI Camera Input - Using Video Capture Grabber

ktomcz2 · June 6, 2020, 5:57pm

Hi,

I am trying to feed the HDMI output of the FLIR Duo camera into the Jetson TX2. The most affordable solution I have found so far was to use an HDMI-to-USB3 converter. Although the weight of it might be the down side. Another obstacle is the fact that the Jetson runs on Linux, so I’m not sure of the compatibility of the video grabbers with that operating system.

Has anyone ever done this with the FLIR Duo or any other HDMI-output cameras?

FLIR Duo: Support for FLIR Duo | Teledyne FLIR

HDMI-to-USB3 Converter: Amazon.com

Any suggestions would help greatly.

Sincerely,

Krystian Tomczuk

Hi Krystian,
I have connected the Flir Duo with the Jetson Nano via an HDMI to USB3 adapter, see images.
Google: if-link Video Capture-HDMI to USB 3
At the moment it is not available.

With
sudo apt-get install v4l-utils

v4l2-ctl --list-formats-ext -d /dev/video1

you will see something like the output below:
Now you can choose one of the resolutions.

ioctl: VIDIOC_ENUM_FMT

Also I have connected a Flir Vue and a Sony RX0 with two of this devices, see images.
