Help trying to grab video stream from a device
Posted: 23 Apr 2015 22:39
A group of us in the RC hobby forums had started trying to use a device called the 802W, it takes RCA in and then broadcasts it back out over a WiFi you connect to via an Android or iOS device. They're typically used for backup camera addon systems for vehicles. We want to use it to do FPV (First Person Video/View) with using smartphones instead of buying more expensive FPV goggles.

The problem is you can only use their application WIFI_AVIN or WIFI_AVIN2 from the app stores to connect to it because they don't publish the information about how to grab the stream data. We want to write our own apps that can use the stream to better show the information. We've tried using VLC to grab the stream from an Android phone or a Windows PC but we've had no success so far. I was hoping someone could look at the Wireshark outputs and might understand what they're looking at better than I am. I "think" it's a UDP multicast being broadcasted but I just don't know enough to be sure.
In the images 192.168.72.33 is my phone and 192.168.72.173 is the 802W device.
Image of what I believe is a UDP broadcast of the video information.
This is what the stream turns into when the device connects using the WIFI_AVIN application.
I appreciate any assistance, thank you!
