. Playtime!!! Will see if I get a gap to poke around with phonestream(er) and straight gst-launch.@tetris11_: here is a thread that suggests an addition to phonestream(er), perhaps? http://talk.maemo.org/showthread.php?t=71326

@ Bingley Joe: are you on Windows? I ask because the "xout" mode uses tcp (right tetrix_11?) and that might be the one to try. But Windows ... well there are gstreamer binaries one could install but 'nix systems are way easier for this.

I was having trouble installing this before, I installed the new package from fapman. Works like a charm.
Just wanted to say Thanks

So, I persist, tho with a 1.5 and a 6 yr old in the house it can be disruptive. Just a bit.
Anyone know a working sdp for mjpeg with VLC?

Well well, lookee here http://talk.maemo.org/showpost.php?p=974950&postcount=1
Good that phonestreamer does more.
Must test it over the WAN as it may well work.... . BTW, I think I know how to do this with gst-launch now...
PS: Smartcam needs the mono libraries. That will be a large install, oh dear.... Beware, the mono libs are from a diablo repo (not bad in itself) but are not optified. Thus 30 mbytes of rootfs will disappear

Smartcam does look promising.....
....though gstreamer seems lighter and less resource hogging somehow...
Tell me how the WAN testing goes! Have you managed to stream anything through the internet yet!?

Xout:
gst-launch-0.10 v4l2src device=/dev/video ! videoscale ! video/x-raw-yuv,width="+width+",height="+height+" ! ffmpegcolorspace ! jpegenc ! tcpserversink host="+host+" port="+port+"
VLC:
gst-launch-0.10 v4l2src device=/dev/video ! ! videoscale ! video/x-raw-yuv,width="+width+",height="+height+" ! dsph264enc ! rtph264pay ! udpsinkhost="+host+" port="+port
Webcam:
gst-launch-0.10 v4l2src device=/dev/video ! videoscale ! video/x-raw-yuv,width="+width+",height="+height+" ! ffmpegcolorspace ! smokeenc ! udpsink host="+host+" port="+port
So for the record:
Xout uses mjpeg codecs and tcp protocols
VLC uses h264 codecs (which is why quality is worse) + UDP
Webcam uses smoke encoding (gstreamer only) + UDP
Though technically you could configure Xout or Webcam to use the same codecs or the same protocols....
(I just didn't because I wasnt sure whether smoke was better than mjpeg...)
===================================
As for receiving:
Xout:
gst-launch-0.10 tcpclientsrc host="+localip+" port="+port+" ! jpegdec ! autovideosink"
Webcam:
gst-launch-0.10 udpsrc port="+port1+" ! smokedec ! ffmpegcolorspace ! v4l2loopback device=/dev/video0
A major advantage using UDP is that you dont have to define which address the signal is coming from, just which port. So maybe that's a starting point right there....
