Overview

voxl-flir-server is an application to send video frames from the FLIR Lepton SPI camera to Modal Pipe Architecture (MPA) pipes. This server is used in conjunction with voxl-streamer. For Flir UVC enabled cameras with USB interfaces such as the Boson 640 and PureThermal Mini Pro with Lepton use voxl-uvc-server instead.

Configuring voxl-streamer to work with voxl-flir-server

The voxl-streamer configuration file /etc/modalai/voxl-streamer.conf needs to have a configuration record for the FLIR Lepton:

"flir": {
    "input": {
        "interface": "mpa",
        "mpa-camera": "flir" },
    "output": {
        "stream": {
            "rotation": 0,
            "width": 160,
            "height": 120,
            "bitrate": 1000000 } }
},

Then run voxl-streamer with this record using voxl-streamer -c flir
