Hi,
Everywhere where I can find information about this webcam it worked well, but I can't make it working.
mjpg_streamer all the time shouts about format:
root@cph4:~# /usr/bin/mjpg_streamer --input "input_uvc.so --device /dev/video0 -r 1024x768" --output "output_http.so --port 8080 --www /www/webcam"
MJPG Streamer Version: svn rev: exported
i: Using V4L2 device.: /dev/video0
i: Desired Resolution: 1024 x 768
i: Frames Per Second.: not limited
i: Format............: JPEG
i: TV-Norm...........: DEFAULT
Unable to set format: 1196444237 res: 1024x768
Init v4L2 failed !! exit fatal
i: init_VideoIn failedI've tried with -y, without, with -n, without and with other resolutions as well. No success.
V4L shows:
root@cph4:~# v4l2-ctl --all -d /dev/video0

Other thing is why mjpeg_streamer shows JPEG instead og MJPEG in format?
Have anyone of you guys had any issues with this cam?
