Applications
LeanXstream is a very simple application for streaming Video (uncompressed).
- Author: baettig baettig
- Download: leanXstream
- License: lgpl
- Oscar Version tested: v1.3-p1
- Watch a live video stream in Windows or Linux
- Save live images to a harddisk as .BMP
- Save video the a harddisk (uncompressed)
- Play video from the harddisk
The leanXstream application takes images as fast as it can and writes them to a buffer. Client can connect with a TCP connection to port 8111. As soon as a client is connected, the camera sends the raw image data over the TCP connection. Multiple clients can connect at the same time, it just slows down the frame rate.
To receive the stream on a client, nc (netcat) can be used. The following command receives the stream and writes it to a file (Video recording)
nc 192.168.1.10 8111 > video.dat
If you want to play the video, simply play the raw data with mplayer:
cat test.dat| mplayer - -demuxer rawvideo -rawvideo w=752:h=480:format=y8:fps=100 -vo x11
There is also a small application which takes the raw video stream from the standard input and writes it to .BMP files. This works like this:
nc 192.168.1.10 8111 | ./writebmps
If you just want to play a live video stream, you connect to the camera with nc and pipe the data directly to mplayer:
nc 192.168.1.10 8111 | mplayer - -demuxer rawvideo -rawvideo w=752:h=480:format=y8:fps=100 -vo x11
Configure the application by executing one of the following commands, depending on the used version:
make config
for the original version linking with Oscar1.3, or, for the version for Oscar2.0:
./configure
And then, independently of version:
make scp leanXstream_target root@192.168.1.10:.
Run leanXstream on camera:
telnet 192.168.1.10 cd /root #(kill all applications that are still running and using the camera, eg. with the following line:) killall *target ./leanXstream_target
In the linux virtualbox
# Play live video stream nc 192.168.1.10 8111 | mplayer - -demuxer rawvideo -rawvideo w=752:h=480:format=y8:fps=100 -vo x11
# Replay the recorded video cat test.dat| mplayer - -demuxer rawvideo -rawvideo w=752:h=480:format=y8:fps=100 -vo x11
There are nc and mplayer versions precompiled for windows. Just download them and use the same commands as above.
A simple alarm system. Stores images as soon as something moves. Built in live video stream.

leanXzebra uses part of the zbar open source barcode library, formerly known as "zebra". Many thanks to spadix for the great work!
For QR Codes and some other features, compiling the full library for leanXcam is required. Check out the experiences and handy instruction of Axel von Arnim here: Compiling zbar for leanXcam.
