(Note1: do not know why, but autoaudiosink was unstable... Audio stopped working after a few seconds...)(Note2: TX host IP address should be receiver/Pandaboard IP address, and RX host IP address should be transmitter/RPi IP address.)
Best Raspberry PI Kit (Recommended!)
Hardware:
Raspberry Pi
PS3 Eye
EW-7781Uh WiFi dongle
Ubuntu machine (Pandaboard ES)
Summary:
Video and microphone streaming over UDP was tested usin PS3 eye camera.
Jpecenc and Speexenc was used for video and audio encoder, respectively.
The audio latency was not so great (~1 sec), but video was reasonable (< 1 sec).
RPi CPU usage was about 98% (top command)
