I got mavlink for autoquad telemetry running with wifibroadcast. Here is some of the code from my RX pi if anyone is interested-

BELOW IS MY POST FROM RCGROUPS>
For TX I was just using derelicte's image as it seems to be pretty lightweight.
For the RX I used Befi's .4 tx/rx image then followed Rangarid's instructions here-
https://github.com/SamuelBrucksch/wifibroadcast_osdThat got openvg built and alot of the osd code. Then I compiled Mavlink for autoquad here-
https://github.com/mavlink/mavlinkWhich if you are using an autoquad you might not have to go thru that- I think you might be able to just copy my files. Of course there are many other platforms running mavlink.
I then heavily modified everything and then created a few files of my own such as mavlinkparse.c
As it stands now this all should work with LTM, FRSKY, or MAVLINK depending on how you configure osdconfig.h
For me running an autoquad m4 n4 combo I had to run rx and tx wires to the rpi a in order to get a readable signal. This was all done at 115200 baud and only has to be set on the tx end.
Currently my rx pi's are being strained by the load. I am going to look into implimenting fifos and some ideas from derelicte's image.
