ezwifi broadcast
https://github.com/bortek/EZ-WifiBroadcast Ez-WifiBroadcast is a radically simple digital data transmission system. A bidirectional data link is established using commercial off-the-shelf hardware like WiFi modules and a pair of Raspberry pi computers. Coupled with special software this unique system allows transmission of low latency HD video, telemetry and control data between endpoints. In comparison to a classical wireless connection Ez-WifiBroadcast tries to imitate the famous properties of an analog link like graceful signal degradation and no association between the endpoints.

ezwifi wiki faq What is the minimum hardware I need to try this? Two Raspberry Pi, two WiFi dongles, one Pi cam, and 2 micro sd cards. Please read the rest of the wiki and do your homework when you make your purchases! Some Pi aren’t compatible, most WiFi dongles won’t work, and you need big enough micro sd cards.

Issues: The problem with Ez-wifibroadcast is that most of the WiFi dongles it used are no longer available. TPLink has unfortunately upgraded the WiFi chipsets in its dongles and routers to more proprietary Mediatek/Realtek chips which don’t have the right drivers for injection mode. That is correct, you can boost the range by upgrading the WiFi router. A Cantenna might be a cheap and interesting option to boost the range (especially after pairing it with Ardupilot’s AntennaTracker). Latency is configurable in APStreamline and the trade-off is that the jitter will increase as the latency is reduced.

https://discuss.ardupilot.org/t/introducing-apstreamline/31723 The APSync 25 project currently offers a basic video streaming solution for the Raspberry Pi camera. APStreamline aims to complement this project by adding several useful features: Automatic quality selection based on bandwidth and packet loss estimates, Selection of network interfaces to stream the video,    Options to record the live-streamed video feed to the companion computer,    Manual control over resolution and framerates Multiple camera support using RTSP,   Hardware-accelerated H.264 encoding for the Raspberry Pi Camera settings configurable through the APWeb GUI,    Compatible with the Pi camera and several USB cameras such as the Logitech C920 and others.

Due to the limited range of 2.4GHz Wi-Fi, the Quality-of-Service (QoS) progressively gets worse when the robot moves further away from the receiving computer. This project aims to fixes problem by dynamically adjusting the video quality in realtime. Over UDP we can obtain estimates of QoS using RTCP packets received from the receiver. These RTCP packets provide helpful QoS information (such as RTT and packet loss) which can be used for automatically changing the bitrate and resolution of the video delivered from the sender.

http://unmannedbuild.yconst.com/2017/01/28/controlling-wifibroadcast-with-an-rc-switch/ Wifibroadcast is a project aimed at the live transmission of HD video (and other) data using wifi radios. One prominent use case is to transmit camera images for a first person view (FPV) of remote controlled aircrafts. In contrast to a normal wifi connection wifibroadcast tries to mimic the advantageous properties of an analog link (like graceful signal degradation, unidirectional data flow, no association between devices).

Tower app streaming
https://github.com/DroidPlanner/Tower/wiki/Custom-video-stream I am reporting how to stream Raspberry pi camera video to Tower video widget. On the last weekend, I attended a drone meeting. I brought my IRIS which was given from my friend. It flew well and I was very satisfied with my first flight. In the meeting, other people brought their brand new drones like SOLO, Phantom, and Inspire. I had a chance to fly them and I felt something was missing in my old IRIS. It was FPV! I live in Japan and because of a regulation, we can't use a 5.8GHz video transmitter without a licence. Furthermore, SOLO costs twice as in USA. However, I noticed a video widget(small screen) in Android "Tower" app and it was said that it receive custom video streaming. In that article, the author used Ubuntu as the source. Since I had a raspberry pi 2 with pi camera, I had tried to use it as a FPV camera server. The followings are how to set up video streaming. I hope it will work with your environment. Google cardboard support thanks to the integration of the DronePro app by Shawn Fraser https://play.google.com/store/apps/details?id=meavydev.DronePro Improved Mission Editor. Added support for the Reset ROI mission item. UX update for the telemetry connection preferences Removal of the droneshare account integration pending rehabilitation of the site api.

flytpod wi-fi
It has an inbuilt High Power WiFi, RC Receiver Support, External 3G/4G dongle provisions and a Serial Port for Telemetry using external Radio. This enables seamless communication between the Drone and ground applications running on mobile devices or laptop. It also allows for communication with cloud apps as well as between multiple Drones in a fleet (Swarm).

FlytPOD is the most advanced flight computer available in the market today. It has the complete flight stack for reliable navigation and can be attached to any type of drone. This includes inertial navigation sensors, barometer, GPS, communication system and several payload interfaces. It also contains a powerful processor for developing custom high level applications for agriculture, industrial inspection, surveys, search & rescue and delivery, etc.

It boasts of a Samsung Exynos5422 Octa-core processor, with 2 GB Ram, a powerful Integrated GPU and 32 GB storage (upgradable). This allows for onboard processing of computationally intensive algorithms like image processing, obstacle avoidance and mapping the environment. It embodies an external Safety Switch, RGB LED for system status, USB3.0, USB2.0, HDMI and user configurable I/Os. It has 3-axis Accelerometer, 3-axis Magnetometer, 3-axis Gyroscope, external dual GPS and Magnetometer.

http://flytbase.com/flytpod/ We have tested it for 250 meters with ping time of 5ms with ASUS router on ground. Baud rate wouldn't be a good major to rate it on, but we have tested file transfer successfully at 250 meters with ~ 100 Kilo Byte per second. Within 100 meters the performance is great with video and telemetry data. With onboard 20 dBm output power and decent ground router we expect the range to be more than 500 meters. We are planning to test for 500 meters soon.

 * EmbeddedPc:Pandaboard Base for my UAV experience. The transmission is incredibly stable, the video is really smooth. Here is what i used: -Logitech C920, a good quality camera.

-Pandaboard: has an embedded video encoder that can take the raw YUV video from the camera and encode it in h264. You can set the encoding quality/bitrate and other parameters.

-HSDPA usb dongle; 60 hours of high speed connection for 10€/month, i have a 2Mbps upload speed with this little beast. Ping increases during workload and reaches 250ms, when unused, it's as low as 50ms.

-The traffic is sent from the pandaboard to a VPN i connect with my client. This is only a way to bypass firewalls. 864x480 works but it's not as smooth as 360p, and i consider the 360p streaming to be more than enough for this. 1280x720 lags considerably. If there is interest maybe i can publish my code and a video of how it works. Anyway, i'm a happy guy and i wanted to share it. I've never tried radiofrequency video transmission, but was worried about the range.

Although the video shows devices in one place, but you can make the same scenario using devices in different locations, even different continents, as long as they have Internet connection via ADSL 3G or 4G. Video quality depends on sender mobile, network and the receiver device. The streaming protocol handles network bandwidth intelligently and adapt video quality according to bandwidth availability, also processing power of the receiving device determine video smoothing and glitches.
