Hello,
I wanted to set up a videoconference service at my company using a sony
video camera with a usb video capture device and linux (Ubuntu to be
specific). The videoconference system we're using is through webex and
megameeting. I am currently using an Avermedia video capture device but
the problem I had was that for this device the default input was "Tuner"
and even dough I could set the default input to S-Video with v4l
utilities this would only work with mplayer, vlc... but it wouldn't work
with flash or java in a browser which are the technology behind most of
online videoconference services. So after a month of banging my head
against the wall I gave up and installed another operating system.
Windows. Yes, I know.
But now I want to give it another try so this time I was thinking of
trying with another video capture usb device so I wanted to ask the
members of this list if you ever made one of this devices work perfectly
under linux, specially with flash or java technologies. I think I would
have the same problems with any Avermedia device so maybe there's
something out there that works.
Thanks for your help,
Have a nice day

I am using a Logitec USB webcam and it works with flash. I have noted
that it does not work with all versions of flash. So I have a specific
version that I do not reinstall and then it continues to work. This is
on openSUSE. But I suspect it is the same for all Linux distos as they
cannot change the flash parts.
There is an application called cheese that is great for testing these
devices. If it works there, then you can be sure the OS is doing the
right thing. Which is a good first step.

Thanks for your reply and your advice Roger. Problem is that using a
webcam is not an option right now because the solution that we have to
provide is by using a usb video capture device connected to a camera.
Have anyone tried one of those with linux?

You mean that you have something like a Dazzle video capture device
connected to the USB and a camera attached to that? What usb capture
device are you using? Many are supported. But not all of them.

Yes exactly, I'm using Avermedia EZMaker USB Gold
(http://tienda.avermedia.es/product.aspx?productid=81126). The device
have linux drivers and it seem to work ok but I'm having the problems I
mentioned before.

I use v4lctl to configure devices. The configurations stay until the
devices are repowered. Have you tried this?

Yes, I tried that and v4l2ctl too but some programs like mplayer read
the configuration change but cheese for example or flash didn't. I would
change the default input from tuner (the default) to s-video or any
other kind and nothing.

Hmm. It is not a matter of the program reading your changes. They are
set in the driver. If they are not used, it is because flash is actively
setting a different value from what the driver had when flash started.
This means that flash must have it's own way of specifying these
settings. flash really is crappy...
Perhaps one hack would be to recompile the driver with the defaults you
need. But I suspect even that would fail as it seems flash actively sets
the values. You might try removing from the driver the options you do
not want so they are not available to flash. But I bet flash has some
assumptions that expect these settings, and it would fail if they are
not present.
I don't think I can offer more.

Well, it's weird because I already tried recompiling the driver but
there was no option for changing the default input there. We started to
think here that it is somehow the way the device is supposed to work.
That's why I was thinking of trying with another device. But I'm afraid
that I'll end up facing the same problems.
Thanks a lot for your help Roger and have a good weekend
