FreeBSD: vid_start error

Question

I'm having trouble getting motion working with the pwcbsd driver on FreeBSD. I've installed the latest versions of both (as of today) from the ports tree. The pwc driver seems to be working fine - I can use pwcview to view the output from the cameras. Motion is compiled without the bktr option, and generates an error about vid_start on loading (see below).

Any advice would be much appreciated.

Hi Tim,

i didn't include PWC support patch in port,

Let me update PWC patch to let work against 3.2.9 port.

Hi Angel,

I did what you suggested and applied that patch, but it still does exactly the same thing.

Tim , please get the new version of the patch . It's more verbose to see where could be the problem, moreover i added a patch to fix a ffmpeg issue.

Here it's an output example using 2 pwc compatible cameras.

It still doesn't work for me. And nothing useful in the output. It makes me wonder if I'm doing something stupid, but I don't see what it could be...

Here's the output:

The cameras are detected fine:

pwc0: vendor 0x0471 product 0x0312, rev 1.10/0.03, addr 2
pwc0: Philips PCVC750K (ToUCam Pro Scan) USB webcam
pwc0: This camera is equipped with a Sony CCD sensor + TDA8787 (32)
pwc1: vendor 0x0471 product 0x0311, rev 1.10/0.03, addr 3
pwc1: Philips PCVC740K (ToUCam Pro)/PCVC840 (ToUCam II) USB webcam
pwc1: This camera is equipped with a Sony CCD sensor + TDA8787 (32)
pwc2: vendor 0x046d product 0x08b4, rev 1.10/0.03, addr 2
pwc2: Logitech QuickCam Zoom (new model) USB webcam
pwc2: This camera is equipped with a unknown type of sensor (96)
pwc3: vendor 0x046d product 0x08b4, rev 1.10/0.03, addr 3
pwc3: Logitech QuickCam Zoom (new model) USB webcam
pwc3: This camera is equipped with a unknown type of sensor (96)

I don't think there's anything odd in my config either. I'll attach a diff if I can.

Any more thoughts?

Ok, I got it. I looked at the vid_start function and noticed it doesn't do anything if WITHOUT_V4L is defined. The port Makefile defines WITHOUT_V4L if you don't have the BKTR option selected (which I didn't). Having selected BKTR it now works fine.

Thanks for the help.
