Okay Im getting that exact error message, but ONLY when I run the app with root priveleges...

It works fine if I launch it normally.... hmm....

@CrckMc + justice4all3000 - try launching the app from commandline: "/usr/local/bin/tester", and see if the problem persists... (but not as root)

my front camera led doesn't go off either. is there anyway to switch it off without rebooting the phone?

i didn't actually start up vlc on the pc, just tested things on the phone. should be a really nice app with a little bit more tweaking of the interface.

@leetnoob - it DOESNT? wow, Im so sorry man!
to kill the process run "killall gst-launch-0.10"

@justice - As for recieving the stream on your desktop, you need to generate the sdp file....but since for some reason that aint working, you can just do it manually:
Code:
v=0
m=video 5000 RTP/AVP 96
c=IN IP4 192.168.0.200
a=rtpmap:96 H264/90000
but instead of the 192.168.0.200, replace that with your N900's ipadress. Then save that text to something like "n900videostream.sdp" to your desktop pc.
Then stream from your phone, then launch the sdp file in vlc.

I managed to make the sdp file but still no luck at all are there any settings i need to tweak in vlc?

Any way to use this stream as a webcam?

Can we get audio and video simultaneously?

Nice app!

webcam...really no clue, dude - I kinda doubt it, but more experienced users would probably disagree with me.

as for audio+video simultaneous - really wish I knew how! I've looked though the gstreamer-tools documentation, and it just made my head spin. For now I'm relying on the work of others... so no audio+video together right now....

hmm... as long as you gave the right IP, everything should be fine....

What IP address is your phone, and what IP is your desktop? Do you type the latter into the app before you stream? do you change the sdp file to have your phone's ip?

I have my phone ip set as 192.168.1.109 and my desktop 192.168.1.100 (entered into the app settings before streaming) I have double checked the sdp file and it has my phones ip address in it

okay, apologies in advance for sounding like a complete douchebag, but just to check:
Restart your phone (gst sometimes fails to launch when it's crashed previously)

On your desktop, the sdp file reads:
Code:
v=0
m=video 5000 RTP/AVP 96
c=IN IP4 192.168.1.109
a=rtpmap:96 H264/90000
and on the app on your phone, you've chosen video (this wont work for audio) and the address reads:192.168.1.100, and port reads: 5000.

Then you've clicked stream. After that you've opened the sdp file on your desktop with VLC.

Can you confirm all that in that order?
Again apologies for sounding like a douchebag, I just want to be 100% sure.
