The CAM500B camera module is a 5M-pixel camera with DVP interface. For more tech details about it you can refer to Matrix - CAM500B.

Boot Debian, connect your NEO AIR to a network, log into the board as root and run "mjpg-streamer":

cd /root/mjpg-streamer
make
./start.shThe mjpg-streamer application is an open source video steam server. After it is successfully started the following messages will be popped up:


i: Using V4L2 device.: /dev/video0
i: Desired Resolution: 1280 x 720
i: Frames Per Second.: 30
i: Format............: YUV
i: JPEG Quality......: 90
o: www-folder-path...: ./www/
o: HTTP TCP port.....: 8080
o: usernameassword.: disabled
o: commands..........: enabledIn our case the NEO AIR's IP address was 192.168.1.230. We typed 192.168.1.230:8080 in a browser and were able to view the images taken from the camera's. Here is what you would expect to observe:

The mjpg-streamer soft-encodes data with libjpeg and you can hard-encode its data with ffmpeg which will greatly increase CPU's efficiency and speed up data encoding:

ffmpeg -t 30 -f v4l2 -channel 0 -video_size 1280x720 -i /dev/video0 -pix_fmt nv12 -r 30 -b:v 64k -c:v cedrus264 test.mp4By default it records a 30-second video. Typing "q" stops video recording. After recording is stopped a test.mp4 file will be generated.
