Remoting plugin support streaming image of virtual output on drm-backend
to remote output. By appending remote-output section in weston.ini,
weston loads remoting plugin module and creates virtual outputs via
remoting plugin. The mode, host, and port properties are configurable in
remote-output section.
This plugin send motion jpeg images to client via RTP using gstreamer.
Client can receive by using following pipeline of gst-launch.
gst-launch-1.0 rtpbin name=rtpbin \
udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,
encoding-name=JPEG,payload=26" port=[PORTNUMBER] !
rtpbin.recv_rtp_sink_0 \
rtpbin. ! rtpjpegdepay ! jpegdec ! autovideosink \
udpsrc port=[PORTNUMBER+1] ! rtpbin.recv_rtcp_sink_0 \
rtpbin.send_rtcp_src_0 !
udpsink port=[PORTNUMBER+2] sync=false async=false
where, PORTNUMBER is specified in weston.ini.
