It DOES work with Skype. You have to use gstfakevideo (which then starts up sykpe) with

Code:

gstfakevideo v4lsrc device=/dev/video0

Wireless webcam... nice =)

Re: Use N800 webcam as a Linux Desktop webcam

heyhey =)
I have some questions ^^

"mplayer tv:// -fps 15 -tv device=/dev/video1:driver=v4l:input=1:width=320:height=240"
This does not work on the n810 right?

But the gstreamer

Code:

gst-launch-0.10 -v v4l2src ! 'video/x-raw-yuv,width=320,height=240,framerate=8/1' ! ffmpegcolorspace ! jpegenc ! tcpserversink host=192.168.1.101 port=5434

starts streaming the video signal ( the led lights red).
How can I catch the signal with VLC in windows?

I even tried this :

But I think its useless for the n810 ^^

Re: Use N800 webcam as a Linux Desktop webcam

I got http://wiki.maemo.org/Streaming_vide...uilt-in_webcam working with n810.
You need one script to Tablet and one file to your PC with vlc.
And in tablet there must be package gstreamer-tools installed.

Script to Tablet: (change proper ip-address)

Code:

#!/bin/sh



VPORT=5434

APORT=5432

HOST=PUT_YOUR_PCS_IP_ADDRESS_HERE

gst-launch-0.10 v4l2src ! \

video/x-raw-yuv,width=176,height=144,framerate=\(fraction\)15/1 ! \

hantro4200enc stream-type=1 profile-and-level=1001 ! \

video/x-h263,framerate=\(fraction\)15/1 ! rtph263ppay mtu=1438 ! \

udpsink host=$HOST port=$VPORT dsppcmsrc ! queue ! \

audio/x-raw-int,channels=1,rate=8000 ! mulawenc ! rtppcmupay mtu=1438 ! \

udpsink host=$HOST port=$APORT

File in PC: (call it as n810.sdp)

Code:

v=0

o=- 37 614155991 IN IP4 127.0.0.0

s=QuickTime

t=0 0

a=range:npt=now-

m=audio 5432 RTP/AVP 0

c=IN IP4 172.31.0.245

b=AS:63

m=video 5434 RTP/AVP 96

c=IN IP4 172.31.0.245

a=rtpmap:96 H263-2000/90000

a=fmtp:96

a=cliprect:0,0,144,176

a=framesize:96 176-144

Execute script in Tablet. It say something about pipelines.
In PC type vlc n810.sdp (or start vlc and File->Open->n810.sdp)

Only video, not audio.
You can use resolution up to width=640,height=480.

Re: Use N800 webcam as a Linux Desktop webcam

Hey thank you for the fast answer.

May the sound be a problem of reading data from the wrong device?
Gstreamer is configured to stream sound I think -> "audio/x-raw-int,channels=1,rate=8000 ! mulawenc ! rtppcmupay mtu=1438 ! \"

If you want audio working, try 127.0.0.0 in every IP listed in n810.sdp.

It's working for me under Diablo.

Re: Use N800 webcam as a Linux Desktop webcam

Sorry to revive an old thread but I'm kinda stuck. I'm trying to use my N800 as a webcam for my Windows PC. I managed to stream from the tablet's webcam to my pc (I used vlc to play the stream) but I don't know what to do next. How do I get the PC to recognize the N800 stream as a webcam?

Thanks in advance
