Not all countries and regions regulate drones in the same manner. Always educate yourself on the current laws and regulations of the country, state province or municipality you are flying in. Always fly safely.
For this use case you will need to sign up for a trial of Bambuser, you can do so here:
Aerial Photography challenges
Remote-controlled aerial photography poses quite a few challenges. With regards to technical capabilities, you will need following:
- A stable and reliable aerial platform capable of carrying the weight of the camera.
- A good camera system. For cinematic shots, it should have decent optics and be individually stabilized with a motorized 3-axis gimbal.
- A robust radio link to the operator on the ground. Preferably also a video link for real-time monitoring.
- An efficient motor/propeller combination which should result in longer flight time.
- Preferably some autonomy, such as return-to-home function, in case the radio link is interrupted. More creative aspects such as Follow me and Virtual dolly have been popular for a while. Lately, Visual obstacle avoidance is also being introduced.
When you have a platform that fulfills all or at least some of these criteria, the most common workflow is to record HD video and photos to an onboard SD card for later use.
Adding live streaming
To add live streaming, you could consider mounting a 4G/LTE device directly to the aircraft and broadcast directly to any nearby cell tower.
If there were fully autonomous drones that were legal to operate without a human on the ground, it would perhaps be the way to go for ultimate reach.
However, in most practical scenarios we have an operator on the ground within line of sight of the drone. To be able to compose stunning shots, a video link to the ground is often desired and nowadays several of the available options are digital and of fairly high definition. This makes the spot of the ground operator a good place to pick up a video signal for broadcasting.
Case study: DJI Phantom
DJI is a market leader in off-the-shelf multi rotors, who tends to consistently get good marks on all of the points above and is an option to consider when you need something that works out-of-the-box.
DJI is probably not the only brand supporting live streaming to Bambuser, but the key to simple live streaming from drones is to look for built-in RTMP forwarding capability, which DJI offers.
This guide will focus on how to broadcast using the RTMP protocol from a DJI Phantom 3 Professional and should also be applicable to later Phantoms as well as DJI Mavic and the DJI Inspire series.
DJI's handheld remote control includes an HD video receiver.
HDMI output exists as an optional extra, this is a viable way to live stream if you involve additional pro gear, which is not always desirable in the field. However most of the time the operator also attaches their phone or tablet to the remote control via a USB cable, to act as a display for the live feed and telemetry via the DJI GO app.
Conveniently, this app also has support for forwarding to various online services, including the Bambuser.
Configuring live streaming in DJI GO
Start up the drone and the controller.
Keep the propellers off for safety, unless you are in the field and intend to fly!
Attach your iOS or Android device via USB to the controller and launch the DJI GO app.
Enter into the
Open Settings (marked
...) and in General settings, scroll down to
Select Live Broadcast Platform
Create Custom Live Broadcastdialog, enter as
RTMP URL, an RTMP Input created in Bambuser Dashboard.
In the DJI GO app, concatenate Bambuser Dashboard's
keyvalues, separated by a forward slash
url: rtmp://3fc7ccef.fme.bambuser.com/b-fme key: f11a03d04dce3233f91b3742a0112f03195e937a
produces this value for the DJI GO app
Tap next followed by start.
The app counts down from 3 and the live stream starts. A live streaming indicator appears in the top left corner and allows you to start and stop live streaming independently of other Drone operations (such as the photo controls on the right hand side, which affects the recording to the onboard SD card).
Your live stream now appears in your Bambuser Content Dashboard and can be incorporated in your real time video workflows just like other content you ingest to Bambuser.
You can now ensure the RTH point has been set, take off and have your flight live streamed to the world. Once set up, the live streaming can be started and stopped while in the air, should you desire not to include the takeoff and landing in the broadcast.
After landing the aircraft and moving the onboard SD card to your computer, you could upload any full 4K quality recordings and photos you produced during the flight to Bambuser, should you so desire. Look for the upload form in Bambuser.
