No. videodev.o allows only one process to open the device. Any chance
that this can be changed? Alan? I'm thinking about allowing multiple
opens on bttv, but this needs quite a few changes in videodev.o. Most
serious problem is that I need some way to keep per filedescriptor data
to get this right.
Even if this limitation is removed there is still no sane way to allow
multiple processes to use capture in parallel. Use video overlay and
capture in parallel would work throuth...
