Very first attempts at geting a Phillips webcam working with PDP aren't going so well yet. OS = Gentoo, 2.6.4-ck kernel.
The cam is using these modules:
bash-2.05b# lsmod Module Size Used by
<snip> pwc 49840 1 videodev 7936 2 pwc <snip>
bash-2.05b# lsof | grep video pd 7220 root mem CHR 81,0 1315 /dev/v4l/video0 pd 7337 root mem CHR 81,0 1315 /dev/v4l/video0 pd 7338 root mem CHR 81,0 1315 /dev/v4l/video0
Anybody have some insight into the following error?
pdp_v4l: opening /dev/video0 pdp_v4l: cap: name Philips 740 webcam type 1 channels 1 maxw 352 maxh 288 minw 160 minh 120 pdp_v4l: picture: brightness 32256 depth 24 palette 15 pdp_v4l: channel 0 name Webcam type 2 flags 0 pdp_v4l: switched to channel 0 pdp_v4l: buffer size 304128, frames 2, offset 0 152064 pdp_v4l: VIDIOCMCAPTURE: format not supported: Invalid argument pdp_v4l: no device opened pdp_v4l: attempting auto open pdp_v4l: opening /dev/video0 pdp_v4l: error:
Maybe I should recompile PDP with explicit phillips webcam support?
TIA, d.

will not help as it seems the pwc module is correctly loaded when pdp_v4l is activated...
try: emerge pwcx
it's the proprietary module binary for philips based cam it "enhances" the basic pwc module.

Hi all,

Happy to report that usb-pwcx works on both 2.4.23 and 2.6.4 kernels. Had to rmmod pwc and then modprobe [or even insmod --force] the pwcx module, but after that, the cam works with PDP.
I get very regular glitches in the video stream, however. I imagine that some tweaking of the settings are necessary to get an uninterrupted vid stream in PD. Any tips?
thx, d.

it seems to happen when the webcam is called then closed, then called again.
workaround: unplug the cam plug the cam init the webcam with a single bang launch the metro

Yes, does the trick! Just don't unplug the cam while PDP is running! ;-)
