[AG-TECH] Problem with firewire camera and H261 video producer

[Steve Gaarder]

I am setting up a small AG node with 3.1 on Ubuntu Hardy.  I have a 
Unibrain Fire-i firewire camera.  I can use vloopback and dc1394_vloopback 
to get a nice 320x240 or 640x480 stream with the H.264 video producer, but 
the older H.261 does not work, giving me odd patterns of mostly green 
diagonal lines.

I read somewhere that VIC expects RGB 16 bits per pixel. This may be my 
problem since the firewire setup offers only RGB 24 bit, YUV 422, YUV422p, 
and YUV420p.  I could modify dc1394_vloopback to convert the video, but is 
there an easier way?

thanks,
