hi everybody!
i'm new to v4l and i lack some linux knowledge as well (i know, so please no
rtfms, this is very important to me)
i installed a impact vcb video card on my debian system. the card features
3x video in and is supposed to support capturing from all these inputs
simultaneously. i managed to capture video from one input using the "motion"
utility set to /dev/video0 input0, so all v4l settings seem to be ok.
now my problem: i want motion to capture video from all three inputs, but i
only got one video device. i tried to make multiple motion threads using
inputs 0,8 etc. but (of course) motion starts the first thread with
/dev/video0 and complains about a busy device when trying to start the
others.
how can i make v4l kinda emulate some video devices (that are set to the
different inputs of the card), when only one real device exists? or am i
totally wrong with that attempt and is there a better solution? (like
insmoding some modules more than once with different parameters)
Module Size Used by
bttv 53616 1 (autoclean)
videodev 4736 3 (autoclean) [bttv]
i2c-algo-bit 7200 1 (autoclean) [bttv]
i2c-core 12848 0 (autoclean) [tuner tvaudio bttv
i2c-algo-bit]
(part of lsmod output)
any suggestions?
please help a desperate newbie
