Quickcam VC

Question

Hello, I'm sorry, but my English not good...

I install a Quickcam VC with parallel-port and video2linux (tells me the description). It will work fine with xawtv. But with MOTION I get the error below.

What can I do? Is it possible to ge a connection to MOTION

Thanks and regards from Germany

Gerhard

Answer

Hi Gerhard,

Umm my guess is that driver for your your camera didn't support mmap , only read mode that motion doesn't :

[1] Error requesting buffers for memory map.: Invalid argument
[1] VIDIOC_REQBUFS: Invalid argument
[1] ioctl (VIDIOCSCHAN): Invalid argument

So try to ask about to driver developer/s :
