I. Background analysis
In recent years, China’s domestic uav market has exploded with the introduction of aerial photography into the public. Uav has been widely used in public safety, emergency search and rescue, agriculture and forestry, environmental protection, transportation, communications, meteorology, film and television aerial photography and other fields. Drones have made aerial photography accessible to the general public, making it easy to take pictures previously only available to professional aerial photographers. The solution provided by TSINGSEE Video allows real-time aerial footage to be posted to the webcast.
Ii. Program analysis
In fact, the principle of uav livestreaming is very simple. We have also proposed a lot of uav livestreaming solutions before (UAV video streaming and streaming livestreaming solution EasyDSS escorts forest safety). Here we make a simple classification.
One is that the pictures taken by the camera of the UAV are transmitted back to the ground terminal through the picture transmission system, and then the ground terminal uses the wireless network to broadcast on the platform cooperating with the manufacturer through the APP. Some can also input the stream address, and the aerial pictures can be transmitted to almost any live broadcast platform in real time.
The other is that the entire system needs to have two 4G access points, one on the drone and one on the controller. The PC sends instructions to the DRONE through a wireless network connection to control the flight path of the drone. Meanwhile, the drone sends high-definition videos shot by the built-in camera to the user, who broadcasts live on the live broadcasting platform through the wireless network.
Iii. Plan deployment
Here we talk about the implementation of the first way to push the flow. The advantage of this method is that the live broadcast platform is unlimited, and the live video can be watched through any terminal, such as mobile phone, web page, mobile phone, PAD, etc.
From the above scheme, we can see that the DRONE will stream video to Android device, and Android service can output RTSP stream. By integrating TSINGSEE Tsingxi Video SDK-EasyRtsplive, the video stream is pulled and pushed (RTSP RTMP stream is pushed to the public network streaming server). When the RTMP live stream is pushed to the public network streaming server software EasyDSS, the video is distributed. Output RTSP, RTMP, HLS, HTTP-FLV, and websocket-flV live streams for full terminal live broadcast.
4. Advantages of the scheme
1) Simplicity
Aerial live shooting can be watched on multiple terminals, and the address of live broadcast can be shared with relatives and friends through social networks in advance.
2) Full HD support, free adjustment
Support 720p, 1080p, 4K HD, ultra HD video live effect, any scene can clearly collect and watch the video.
3) Full network coverage, elastic expansion
With full terminal support, users can view videos through web pages, API call integration, and scan codes. Meanwhile, users can transfer videos to third-party CDN for network distribution.
4) High serviceability
Support 7*24 hours service to provide higher stability.
5) Live storage and on-demand support
The audio and video content of live broadcast can be stored in the cloud for users to review the history and play it on demand at the same time to share the wonderful aerial shot just now.
