Does anyone know if it's possible to use the N900 front camera as a usb webcam for Skype. I've had a quick look around but people are talking about wireless streaming which i want to avoid if possible (cos it's far to complicated for me)
Just want simple usb webcam mode?

Nothings been made like that yet I'm afraid. You could try the network based ones like livecast.

Here's a strategy I tried to do but gave up on:

1. Stream cam's video over IP via gstreamer (many examples if you search)
2. On laptop create a "Virtual Camera" (a webcam identified by the laptop/pc) that captures this stream.
3. Use skype, gtalk etc... which would connect to your virtual camera and take the feed from there.

I was able to do the first, the second step is tricky...

Hope this helps.

Can you post some examples of gstreamer over IP as I have tried all the ones I could find from google and not had a lot of success with them.

i managed to get the n900 to stream a selection of jpg images to my PC, and got the PC to interpret that as a webcam (using someone elses drivers).

I never got a chance to swap the list of jpgs for a gstreamer stream but it shouldn't be too difficult...

i remember that i once had coneted a v4l device via Network to a windows device directly as twain input. No gstreamer, the device it self was adressed.
As far as i remember it was tricky and i never got it to work perfect (packetdrop was fatal as far as i remember)

I am able to take videocall to sip:500@ekiga.net
It is an echo test, so your audio and video (from the front camera) is routed back to you.

Seems like videocalling is working, when *bad* proprietary (Skype) standards are not used.

I have been using this:
Code:
#Server
gst-launch v4l2src device=/dev/video0 ! videoscale! video/x-raw-yuv,width=320,height=240 ! ffmpegcolorspace ! jpegenc ! multipartmux ! tcpserversink host=10.0.0.240 port=5000
#Client
gst-launch tcpclientsrc host=10.0.0.240 port=5000 ! multipartdemux ! jpegdec ! autovideosink
Some distributions have gst-launch named gst-launch-0.10.

But to use it as web-camera, you need to create virtual v4l2-device from it afaik, but I couldn't manage to get it working:
Code:
$ gst-launch tcpclientsrc host=10.0.0.240 port=5000 ! multipartdemux ! jpegdec ! v4l2sink device=/dev/video0
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: Cannot identify device '/dev/video0'.
Additional debug info:
