elo
i'm fiddling around with my new webcam, a creative optia af. I want to be able to run this camera under ubuntu feisty with gem and pdp. I had to make again a big research until i found this: http://linux-uvc.berlios.de/ . Now the only application that can run this camera is luvcview. I cannot run right now my webcam with Gem nor Pdp nor xawtv and all other webcam applications.
Gem (from ubuntu-repo) gives me this error:
GEM: Graphics Environment for Multimedia GEM: ver: 0.90 GEM: compiled: Feb 16 2007 GEM: maintained by IOhannes m zmoelnig GEM: Authors : Mark Danks (original version on irix/windows) GEM: Chris Clepper (macOS-X) GEM: Daniel Heckenberg (windows) GEM: James Tittle (macOS-X) GEM: IOhannes m zmoelnig (linux/windows) video4linux ieee1394 for linux Direct Rendering enabled!

Pdp gives me very the same error:

Thanx for any help

Pdp gives me very the same error:
pdp_v4l: cap: name UVC Camera (041e:4058) type 1 channels 1 maxw 1600 maxh 1200 minw 48 minh 32 pdp_v4l: picture: brightness 33825 depth 16 palette 8 VDIOCGCHAN: Invalid argument pdp_v4l: auto open failed pdp_v4l: no device opened pdp_v4l: attempting auto open pdp_v4l: opening /dev/video0
could be that the driver doesn't return the right number of channels here.
did you compile pdp sources? in this case, in this part of the code :
/* get channel info */ for (i = 0; i < x->x_vcap.channels; i++) { x->x_vchannel.channel = i; if (ioctl(x->x_tvfd, VIDIOCGCHAN, &x->x_vchannel) < 0) { perror("VDIOCGCHAN"); goto closit; } post("pdp_v4l: channel %d name %s type %d flags %d", x->x_vchannel.channel, x->x_vchannel.name, x->x_vchannel.type, x->x_vchannel.flags); }
and comment "goto closit" like this :
// goto closit
mmm, i dunno if that can help, suerte, sevy
