Hejsa,

Jeg har siddet og fedtet med webcam-server 0.50 (på Zenwalk 5.2) hele dagen.

Håber nogen her har mere check på den størrelse, end jeg har, og kan bidrage
med et par hints :)

Min mistanke er rettet mod en sammenblanding af v4l og v4l2 drivere/libs,
eller måske udev ikke kan finde ud af dette webcam (logitech bla. bla. pro).

Det startede med at gå "rimeligt". Compile, install og start gik smertefrit.

webcam_server \
  -g 640x480 \
  -p 81 \
  -d /dev/video0 \
  -c "%d/%m/%Y %H:%M:%S - serving %%v viewers at %%f FPS"

Log siger: 2009-04-23 12:35:48 [/dev/video0] webcam_server started

Hertil er alt godt, lige indtil jeg peger firefox på http://server:81

Log siger: 2009-04-23 12:36:22 [/dev/video0] 10.0.0.47 connected via HTTP

Men på consolen hvor webcam_server kører (i forgrund) får jeg en strøm af:

get_cam_image(): len != img->bufsize, just letting you know
get_cam_image(): len != img->bufsize, just letting you know
get_cam_image(): len != img->bufsize, just letting you know

Samme resultat med medfølgende java applet.

Efter en gennemgribende opgradering af alle pakker/libraries, der kunne tænkes
at have noget med sagen at gøre, er det ikke mere muligt at starte webcam_server.

Output på consollen er:

ioctl (VIDIOCSPICT): Invalid argument
error setting video device parameters, using defaults
ioctl (VIDIOCSPICT): Invalid argument
not a valid video device? quitting.

Hvis jeg hiver usb-stik ud, og sætter det ind igen, får jeg:

syslog:

kernel: uvcvideo: Non-zero status (-84) in status completion handler.
