as marc has pointed out: mjpegtools

you can also use ppmtompeg (on debian this is part of netpbm) to create 
an mpeg out of a series of images (despite of the "ppm" in the name they 
can also be jpegs)

so the current problem is freezing (not just being unable to connect to 
the driver) ?
are you using pd's realtime flag ?

you could try running everything in gdb and then kill the process when 
it freezes and then get a backtrace to see where it was when it froze.
