Its got lots of pixelation.

Anyone got it working with ffdec_h264?
Everything I try on the n900 basically spits out: could not link videoscale/v4l2src/whatever to ffdec_h264
Anyone?

Bumping thread up, cant see it on the first couple of pages

No one has tried higher quality streams? The furtherest I got was use jpegenc, the quality was great but I could figure out how to get it to /dev/video0, it would only show up in its own window.

What feature of putty did you mean? The only grafical feature that comes to my mind is X-forwarding.

I figured it out if anyone cares.

n900:
Code:
gst-launch v4l2camsrc device=/dev/video0 ! videoscale ! video/x-raw-yuv,width=640,height=480 ! ffmpegcolorspace ! dsph264enc ! rtph264pay ! udpsink host=192.168.2.14 port=1234
pc:
Code:
gst-launch-0.10 udpsrc port=1234 caps="application/x-rtp" ! rtph264depay ! ffdec_h264 ! ffmpegcolorspace ! v4l2loopback device=/dev/video0 sync=false
I get a small delay though and a weird green tint.
Can anyone else test it?

EDIT::
I changed it to use jpeg instead of h264, seems to a lot less delay, the tint is still there though.

n900:
Code:
gst-launch v4l2camsrc device=/dev/video0 ! videoscale ! video/x-raw-yuv,width=640,height=480 ! ffmpegcolorspace ! jpegenc ! rtpjpegpay ! udpsink host=192.168.2.14 port=1234

But Linux is really easy to use so maybe try Ubuntu.

Doesn't the VLC player got a way to use it's output as the video feed of a virtual "webcam" ?

I haven't tried this yet, actually i didn't even knew about this one before finding it with Google, try at your own risk:

http://sourceforge.net/projects/vlvc/



edit: erm, sorry it seems it might not be what you're looking for....

Hi,

Thanks for the great work. I can now get the video streaming via WIFI (though there is a bit of a green tint to the screen). Has anyone been able to get the camera to stream vie bluetooth yet. This would be much better for me to use.

Cheers for any help.
