Hi, i tried any kind of configuration, but it keeps telling me “can’t get rgb24 data”.
I’ve tried add, remove, edit and comment the norm= parameter. but with no luck.
Any idea?
thank you.

I made it work only by commenting out the “input” line…

“Camera 1?, it’s so easy, your hint to ask “v4l-info” made my day!
Thank you!

I faced the same ftp problem. Fixed by set auto=1 then create a ~/.netrc file

machine http://ftp.host.com
login xxxx
password xxxx

@jo
the only hint I can give atm, is to try the ftp connection manually with same user like webcam user, and see if that works.
Another point is the availability of the image. You should get the same error, if the image from your cam is not there, or not there yet for being uploaded by your ftp client. If your [grab] and [ftp] section in your .webcamrc is swapped, try it the other way round.
And if the error occurs, is you /dev/video0 still available? Dies your cam maybe?

If all fails, try to give Google a chance by searching for “ftp: connect failed, sleeping 5 sec”, but I guess you did it already anyway.

Regards,
Andreas

Thanx, very helpfull hints …
… but i got another problem:

[me@core9 ~]$ webcam &
reading config file: /home/me/.webcamrc
ftp: connect failed, sleeping 5 sec
ftp: connect failed, sleeping 10 sec
…

xawtv (Picture) and Camstreams (Picture & Upload) are working fine. Unfortunatly camstreams sometimes stops uploading after a while.

Any ideas (sorry, i have to use ftp, ssh & locale are already commented out. passive is set to 0, as in camstreams)?

infofile is meant to direct webcam to the file which contains the info to show on top of the image.

So it basicaly it provides webcam with the same info as “text = ” does.

strace shows the file it is trying to open is called “filename” because of this line in the .webcamrc file:

infofile = filename

I commented that line out and the messages went away. Not sure what info this file is supposed to provide.
