webcam streaming theo+vorbis+ogg : segfault?

[jpzone]

I am trying to stream webcam with http and facing some problems.

initially I was using following settings to stream and it worked great -

./vlc -I dummy v4l:/dev/video0:norm=secam:frequency=543250:size=640x480:channel=0:adev=/dev/dsp:audio=0 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,vt=800000,keyint=80,deinterlace} :std{access=http,mux=ps,dst=192.168.0.1:8080}' --ttl 12

I actually want to change the my codecs and mux to theo+vorbis and ogg combination becuase of several reasons. Here where the problems start -

I have compiled vlc with following options - (majorly to avoid ffmpeg, no gui, add theo+vorbis+ogg)

./configure --prefix=/home/phpathak/dod/dod-vlc/in/ --exec-prefix=/home/phpathak/dod/dod-vlc/de/ --enable-nls=no --enable-optimize-memory --enable-vlm=no --enable-growl=no --enable-notify=no --enable-mad=no --enable-v4l --enable-gnomevfs=no --enable-libcdio=no --enable-libcddb=no --enable-cdda=no --enable-vcd=no --enable-screen=no --enable-ogg --enable-libmpeg2=no --enable-vorbis --enable-x11=no --enable-xvideo=no --enable-glx=no --enable-xinerama=no --enable-opengl=no --enable-freetype=no --enable-libxml2=no --enable-skins2=no --enable-wxwidgets=no --enable-visual=no --enable-daap=no --enable-bonjour=no --enable-gnutls=no --enable-hal=no --enable-flac --enable-theora --enable-ffmpeg=no

now with minimal changes I try running the vlc streaming again with following -

./vlc -vvv v4l:/dev/video0 --sout '#transcode{vcodec=theo,vb=192,scale=1,acodec=vorb,ab=96,channels=1}
:std{access=http,mux=ogg,dst=192.168.0.1:8080}'

upon running this I get -

...
...

This continues for ever.. until the laptop gets hung and I manually reboot it.
when I try to capture the stream on the receiving side, vlc players ends up giving "segmentation fault"...
testing on XP clients vlc crashes too..

I believe this has got something to do with theo+vorbis+ogg combination because it was working previously.
Or this might be something else which is completely out of my understanding...
should I change anything while builing or running or what??

Please help me by providing some clue. I need to get it working in 2 days..

thanks

Someone please help with this..
I am really stuck..

Someone must have used this for streaming...
thanks

No cure or workaround to advise, but I have traced it to Theora. Ogg by itself seems to work fine.

Strangely, however... Ogg + Theora is fine under Mac OS X. Just Win and Linux have the problem.

Hey Mike!
Would you be able to develop a bit ?

Hey Mike!
Would you be able to develop a bit ?

This is a possibility, j-b. OGG+Theora would be an excellent solution for a particular bandwidth-limited client... if it worked on an i386 platform. I'm almost at the point where I say "You didn't see me install a Mac as your video server. Move along now."

Actually, this begs the question of whether it still works under OS X. My test platform has been a PPC mini. Let me get an Intel Mac on the bench here and see if we can still transcode.

i need the code that make VLC streams from web cam to icecast server , any one knows?
i tryed using this code:

Code: Select all

and VLC stoppes at this line , and no data appears , counters equal 00:00

no data appears

I validate that VLC can open web cam and audio without streaming

my platform is windows XP

please can some one help me ????????????????

Thanks and Regards
