Installing Computer-Modules’ VidPort SD/HD™ on Debian Lenny

So last friday I received 2 VidPort SD/HD cards in the mail. They come at a very reasonable price compared to some other HD-SDI input/output cards out there!. Heres a quick ‘howto’ to get this card working on linux (debian 5/lenny).

Get your linux headers and build tools

apt-get install build-essential linux-headers-$(uname -r)

Download, Compile, and load card modules

wget http://www.computermodules.com/drivers/master-2.7.1.tar.gz
tar -xvvf master-2.7.1.tar.gz
cd master-2.7.1
make
make install
modprobe hdsdim

If you look at your dmesg, you should see the card loaded.

dmesg
[  393.979657] PCI: Setting latency timer of device 0000:02:00.0 to 64
[  393.979657] hdsdim: VidPort SD/HD I detected, firmware version 1.0 (0x0100)
[  393.979657] hdsdim: registered board 0
[  393.979657] sdivideo: registered receiver 0
[  393.979657] sdiaudio: registered receiver 0

Now, if you wish to use it, load a transcoding program like ffmpeg

./ffmpeg \
 -f rawvideo -s 1280x720 -pix_fmt uyvy422 -r 60 -i /dev/sdivideorx0 \
 -f s16le -ar 48000 -ac 2 -i /dev/sdiaudiorx0 \

(ofcourse you still have to specify output..)
