 +===== Dronovo poznámky =====
 +Ne zcela s jasnou souvislosti se streamingem videa z labky, ale pár poznámek ze streamingu videa/fotek z vebkamery pripojene k rbpi(3).
 +Pokud stačí típnutí fotky z webkamery...
 +sudo apt-get install fswebcam
 +fswebcam -r 640x480 --jpeg 85 -D 1 shot.jpg
 +Video (ale ani rbpi3 to rozumne nestíhá... možná použít jiný codec...)
 +sudo apt-get install vlc=nox
 +vlc v4l2:// :​v4l2-dev=/​dev/​video0 :​v4l2-width=640 :​v4l2-height=480 --sout="#​transcode{vcodec=h264,​vb=1800,​scale=1,​acodec=none}:​rtp{sdp=rtsp://:​8554/​live.ts}"​ -I dummy
 +Na druhé straně ve vlc pustit network stream z adresy <​code>​rtsp://​ip_addr_rbpi:​8554/​live.ts</​code>​
