"This could be an interesting wifi stick for wifibroadcast. Relatively small, two antenna connectors (inside the case), 2.4Gh/5Ghz support and Atheors AR7010/AR9280 chipset which works with the same ath9k_htc driver as the AR9721 sticks like the…"
"Hmm, not sure what you mean. My knowledge about linux video stuff is limited :) I thought using v4l to get the MJPEG stream out of the cam, then pipe it into wifibroadcast tx application. No de-coding or re-coding done. Then on the receiving Pi,…"
"I think it depends on how you want to use it.
Right now it uses inter process communication, with the tun/tap solution it would be network communication, which is more versatile.
The idea materialized when I wasn't sure if befinitiv would implement…"
"Hey befinitiv, I have seen you have started implementing FEC from udpcast. Thanks, thanks, thanks.
Now I feel bad, because I haven't had time to dig into the buildroot stuff further. But I will do that sometime :)
But I have looked into the other…"
"Two way communication also wouldn't be very good, because it would cause collisions (=video dropouts) when the ground-station sends something at the same moment with the air-station. In this regard wifi works similarly to the "plain old ethernet…"
"The beauty about wifibroadcast is, that it doesn't use "normal" wifi, it just sends out the packets without the whole ack/retransmission mechanism and association thing. There is also no IP or UDP in the packets, it's just the raw video stream.…"
