To use the Sensoray 2250 USB frame grabber:
Ensure you have the following packages installed: build-essential, libusb-dev
Download the Linux manual and linux SDK from the Sensoray website at:
Go to the Software and Manual tab near the bottom to find the links. The software can also be found on the 40m computers at /cvs/cds/caltech/users/josephb/sensoray/
The files are Manual2250LinuxV120.pdf and s2250_v120.tar.gz
Run the following commands in the directory where you have the files.
tar -xvf s2250_v120.tar.gz
sudo make modules_install
At this point plug in the 2250 frame grabber.
sudo modprobe s2250_ezloader
Now you can run the demo with
./sraydemo or ./sraydemo64
Options will show up on screen. A simple set to start with is "encode 0", which sets the recording type, "recvid test.mpg", which starts the recording in file test.mpg, and "stop", which stops recording. Note there is no on screen playback. One needs an installed mpeg player to view the saved file, such as Totem (which can screen cap to .png format) or mplayer.
All these instructions are on the first few pages of the Manual2250LinuxV120 pdf.
