AW: Help with syntax

[Bernhard Graaf]

Please check the source for v4l2src. If it's not "/dev/video0" you should
use the device=xxx parameter for v4l2src (see:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-pl
ugins/html/gst-plugins-good-plugins-v4l2src.html).

I added the line you said was missing and I get an error
"erroneous pipeline: link without source element"
Do you have an example of the working line you suggested I add in?


gst-launch-0.10 v4l2src !
'video/x-raw-yuv,width=640,height=480,framerate=25/1' ! \
timeoverlay halignment=right valignment=bottom shaded-background=true ! \
clockoverlay halignment=left valignment=bottom text="M/D/Y:"
shaded-background=true time-format="%m/%d/%Y %H:%M:%S" ! \
tee name=t_vid ! queue ! xvimagesink sync=false t_vid. ! queue ! videorate !
\
'video/x-raw-yuv,framerate=25/1' ! xvidenc ! queue ! mux. ! \
audiotestsrc num-buffers=440 ! audioconvert \
 audioconvert ! 'audio/x-raw-int,rate=44100,channels=2' \
! lame ! queue ! mux. \
avimux name=mux ! filesink location=testavi.avi

Greetings All 
 
I'm having trouble getting the following line to work
I get an error "WARNING: erroneous pipeline: link without source element"
 
I think I narrowed it down to the audio section but I'm not sure how to fix
it can some one assist?
 
 
 
Thanks  See code below
 
gst-launch-0.10 v4l2src !
'video/x-raw-yuv,width=640,height=480,framerate=25/1' ! \
timeoverlay halignment=right valignment=bottom shaded-background=true ! \

\
'video/x-raw-yuv,framerate=25/1' ! xvidenc ! queue ! mux. ! \

this part above is wrong. You miss your audiosrc element between the 'mux.'
and '!'.

 audioconvert ! 'audio/x-raw-int,rate=44100,channels=2' \
! lame ! queue ! mux. \
avimux name=mux ! filesink location=testavi.avi
