Sensoray 2250 Linux Ver2.0.X - Manual (Page 3)

Software
Feature Summary
The 2250 uses the standard Video4Linux2 (V4L2) API through a Linux kernel module. A
full-featured console demo application allows recording of MPEG video on the host
computer, and control of the compression and video settings. The Video4Linux2 API
allows use of the device with V4L2-compliant Linux applications. The kernel module
also provides an Advanced Linux Sound Architecture (ALSA) interface.
For migration from older 2250 SDK, an included C SDK can be used to integrate video
capture into any application. The SDK allows maximum flexibility by providing an API
for all the 2250’s functions. The source code of the demo application is a suggested
starting point for custom application development.
Installation
The software may be distributed on a CD or downloaded from the Sensoray’s web site.
If the file is downloaded, it will need to be unzipped into a folder on the local drive prior
to connecting the 2250 to the USB port.
The SDK has been developed on Ubuntu LTS and support is provided for this
distribution. The SDK may work on other Linux versions, but this is not guaranteed.
The package libasound2-dev must be installed. On Ubuntu, type “apt-get install
libasound2-dev” if it is not currently installed. On other distrubutions, install
libasound2-dev from the CD or otherwise.
Setup is performed as follows.
1) untar the tgz file. “tar xvfz sdk-2250-linux_vXYZ.tgz” where XYZ is the version
of the SDK.
2) “cd sdk-2250-linux_vXYZ“ where XYZ is the version.
3) Type “make”
4) Type “make install” (enter password as prompted by sudo, or switch to root
user before executing)
5) “./sraydemo” runs the demo application.
