Telepresence

• (HD) Telepresence between FIXME and PTL

• Accelerated video decoding and display on the Raspi
• PTL outgoing bandwidth
• Build a wooden window-like frame with curtains

• 2 (4?) Raspberry PI
• 2 Camera modules
• Custom printed box

/etc/rc.local:

su pi -c "raspivid -t 86400000 -w 1080 -h 720 -fps 30 -b 256000 -n -o - | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:5000/}' :demux=h264" &

Client not yet working on the Raspi...

omxplayer rtsp://localhost:5000

However, this works quite well on a regular PC (video decoding done in software):

vlc rtsp://1.2.3.4:5000/

Gstreamer client?

echo "deb http://vontaene.de/raspbian-updates/ . main" | sudo tee /etc/apt/sources.list.d/gstreamer.list
sudo apt-get update
sudo apt-get install libgstreamer1.0-0-dbg gstreamer1.0-tools libgstreamer-plugins-base1.0-0   gstreamer1.0-plugins-good gstreamer1.0-plugins-bad-dbg gstreamer1.0-omx gstreamer1.0-alsa
gst-launch-1.0 rtspsrc location=rtsp://localhost:5000/ ! rtph264depay ! h264parse ! omxh264dec ! autovideosink
