How to use it

Note: All functions except GoPro.Camera.powerOn() are using Promise

Basics

Create camera object

var GoPro = require('goproh4');

var cam = new GoPro.Camera();

Options can be given:

var cam = new GoPro.Camera({
    ip: '10.5.5.9' /* Gopro ip, should be 10.5.5.9 except in remote mode */,
    broadcastip: '10.5.5.255' /* Broadcast ip of the gopro network, use to wake up the gopro (WOL protocol), should be 10.5.5.255 */,
    mac: 'xx:xx:xx:xx:xx:xx' /* Mac address, used to wake up the gopro, should be set if the camera is off before launching the script, available at cam._mac. Will be retrieved if not present. */
});

Record a video

// Set camera mode
cam.mode(GoPro.Settings.Modes.Video, GoPro.Settings.Submodes.Video.Video)

// Set camera resolution
.then(function () {
    return cam.set(GoPro.Settings.VIDEO_RESOLUTION, GoPro.Settings.VideoResolution.R1080S)
})

// Set camera framerate
.then(function () {
    return cam.set(GoPro.Settings.VIDEO_FPS, GoPro.Settings.VideoFPS.F60)
})

// Begin recording
.then(function () {
    console.log('[video]', 'started')
    return cam.start()
})

// Wait 10s
.delay(10000)

// Stop recording
.then(function () {
    console.log('[video]', 'stopped')
    return cam.stop()
});

Livestreaming from Web browser

Requirements:

• ffmpeg

1. Go to livestream directory
2. npm install
3. node livestream.js (make sure you are connected to your GoPro's wifi before launching this command)
4. Open http://127.0.0.1:8082/index

Settings

All the camera settings can be found in lib/constant.js. Accessible through the object

GoPro.Settings

Settings name are in capital letters:

GoPro.Settings.VIDEO_RESOLUTION

Settings value are in camelcase:

GoPro.Settings.VideoResolution.R1080S

Mode

Change gopro mode/submode using GoPro.Camera.mode(mode, submode)

cam.mode(GoPro.Settings.Modes.Burst, GoPro.Settings.Submodes.Burst.Timelapse).then(function () {
    console.log('[gopro mode changed]');
});

Note: there is an hidden mode called Broadcast, for now I haven't been able to correctly use it, I suppose it's a coming feature.

Status

Get gopro status using GoPro.Camera.status(status_id)

cam.status(GoPro.Status.InternalBatteryLevel).then(function (status_value) {
    console.log('[battery level is] = ', status_value);
});
