[gst-devel] vl4+alsa => theora => icecast

[alejo d]

hej rene, thanks a lot for your explanation, its basically "my" first
pipeline, it comes from some wiki+google+irc so no wonder i had so many
mis-pasted bits...anyway im still stuck, i've tried what you suggested and
got a segfault:

gst-launch-0.10 v4lsrc device=/dev/video0 ! ffmpegcolorspace ! videoscale !
video/x-raw-yuv,width=320,height=240 ! theoraenc bitrate=80 ! oggmux
name=mux !  shout2send ip=hackitectura.net port=8000 password=XXXXX
streamname=http://son0p.tv description= <http://son0p.tvdescription=>"alej00d
live transmission" mount=son0p.ogg  alsasrc ! audioconvert ! audioresample !
audio/x-raw-float,width=32,rate=22050,channels=2 ! vorbisenc ! queue ! mux.

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: audioclock0
WARNING: Element "shout2send0" warns: gstbasesink.c(1935):
gst_base_sink_chain_unlocked (): /pipeline0/shout2send0:
Received buffer without a new-segment. Assuming timestamps start from 0.

any other thing i should try to avoid the trap?

thanks again,
/a
