Okay i have identified the problem when starting multiple instances of
the program:
- If i start the program in resolution 960x720, i can start it twice
without errors.
- If i start the program in resolution 1024x768, i get the following
error for the 2nd instance:
Unable to start capture: No space left on device
i: Error grabbing frames
Maybe a static buffer alloc in the source?
So the question is now... When i will have the 5 webcams (i only have
2 for now), will the "space on device" will be enough to use all cams
at 960x720 at least? =/
Damn...
Damn again...
My misstake, i have unplugged the devices and replugged them... Now
both seem to have the good colors!
No, the table is only used if you want to use a named resolution like
SXGA or VGA. If you pass a certain resolution like 1600x1200 is will
parse the values and tell the driver about the desired resolution.
Have
you tried other, smaller resolutions too? Perhaps i have an issue with
those high resolutions.
Okay, i have added 1600 x 1200 resolution so we will be able to use
the named resolution :)
Thanks Tom, i really feel we're going ahead the good way :)

Hi Pierre,
The output of mjpg-streamer looks good, revision #54 is the most
recent
version.
The picture in firefox is wrong too.
Damn...
Also i have tried the output_file plugin, and set up with the --
folder
thing after looking at the sources to know the parametters to use.
But
this output plugin gives a segmentation fault.
Damn again...
Also a fast question:
in the sources, i see a resolution table which only goes to 1280 x
1024 (Which is SUFFICENT for me, no problem). Does it mean that the
1600 x 1200 is software-side interpolated? What if i add UXGA 1600
1200 in the table? :)

For now, i would be more than happy if the HTTP output plugin can
give
me "real" colors. Any clue for this please?
If i would know better i would already have a fixed code. So i am
afraid
we have to go bug hunting. Considered your tight schedule you may want
to try something other and come back to this issues later?
Thanks a lot for your support, for now you're the only person who
provided me with a fast solution... So i place my hope in your
knowledge now :D
I will do my very best, but it is difficult because in my setup it
works
(Ubuntu 6.06 LTS + Linux-UVC #170 + Logitech Sphere AF). So tracking
down the error depends on our descriptions, cooperation and
information.
This is difficult in such a short time.
Perhaps you want to try motion or nakenweb. Those applications should
also "just work", but so far I thought the same about my software
too ;o)
HTH,
Tom
