Hi Mr. Goil
thx for sharing your knowledge! Your hint about xawtv and its tools
helped me a lot.
i couldn't get the MovieLayer to read /dev/video0. but i found a
workaround for reading a v4l2 device via vloopback.
It's a silly hack - but it works ok for me (at least for the moment).
so, basically, it's possible to pipe any video input via vloopback to
freej. there is even a way to read dv via dv2vloopback:
https://sourceforge.net/projects/dv2vloopback/
still, wouldn't say *no* to a real implementation of v4l2 ;)
so this is what i did (if anybody feels like following)
1. build and install vloopack (Kernel 2.6.24-16)
svn co
http://www.lavrsen.dk/svn/vloopback/trunk/ vloopback
cd vloopback
make
sudo make install
sudo modprobe vloopback
2. Install effectv
3. Install xawtv
4. Set the Video Input of my v4l2 device to S-Video
v4l2-ctl --set-input 2
5. Pipe /dev/video0 via effectv (changed i/o size to 640x480)
effectv -device /dev/video0 -vloopback /dev/video1 -size 640x480
6. Read /dev/video2 in Freej via JS:
lay1 = new CamLayer(640, 480, "/dev/video2");
addlayer(lay1);
cheers,
