It works perfect in WebcamStudio also.
One question:

In my prevous gst-launch-1.0 pipe i put pids for the dvbsrc element:

pids=PMT:VideoPid:AudioPid

gst-launch-1.0 --gst-debug-level=3 dvbsrc adapter=0 inversion=AUTO
modulation=AUTO trans-mode=AUTO bandwidth=8 frequency=514000000
pids=423:433:443 code-rate-lp=AUTO code-rate-hp=AUTO guard=AUTO
hierarchy=AUTO ! tsdemux name=demux demux. ! queue max-size-buffers=0
max-size-time=0 ! mpegvideoparse ! mpeg2dec ! videoconvert ! videoscale !
videorate ! video/x-raw, format=RGB, width=320, height=240, framerate=25/1 !
videoconvert ! xvimagesink sync=false demux. ! queue max-size-buffers=0
max-size-time=0 ! mpegaudioparse ! flump3dec ! audioresample ! audio/x-raw,
format=S16LE, channels=2, rate=22050 ! audioconvert ! alsasink sync=false

now i also get it work with  program-number=x

gst-launch-1.0 --gst-debug-level=3 dvbsrc adapter=0 inversion=AUTO
modulation=AUTO trans-mode=AUTO bandwidth=8 frequency=514000000
code-rate-lp=AUTO code-rate-hp=AUTO guard=AUTO hierarchy=AUTO ! tsdemux
program-number=8583 name=demux demux. ! queue max-size-buffers=0
max-size-time=0 ! mpegvideoparse ! mpeg2dec ! videoconvert ! videoscale !
videorate ! video/x-raw, format=RGB, width=320, height=240, framerate=25/1 !
videoconvert ! xvimagesink demux. ! queue max-size-buffers=0 max-size-time=0
! mpegaudioparse ! flump3dec ! audioresample ! audioconvert ! audio/x-raw,
format=S16LE, channels=2, rate=22050 ! audioconvert ! alsasink

... but this one get me sometimes the right audio channel, others time a
service one ...
There is a way to specify program-number=x and audio-channel pid only?
Thanks.
karl.
