Getting pipeline from playbin

[John Faith-2]

Hello,
I'd like to see the element pipeline which playbin uses.  Is there a
simple way to get this?


Thanks!,
John

Graphically: wait until the pipeline/playbin has reached PAUSED or
PLAYING state, then use

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstInfo.html#GST-DEBUG-BIN-TO-DOT-FILE:CAPS



Alternatively: gst-launch-0.10 -v playbin uri=....

will usually also give you a good idea about what elements are involved
(check the element names when it prints the caps of the various pads).

Cheers
 -Tim

Hi Tim,
Thanks for the response!

I was hoping that there was a way to get the pipeline in text (similar
to what gst-launch accepts) without recompiling, but thanks for the
suggestions!

John

I wonder if we should improve this a bit. Currently it lists:
/playbin0/abin/audiosink.sink: caps = aud....

This does not tell you which audiosink it uses. SO what about:
/playbin0/abin/audiosink[alsasink].sink: caps = aud....

It should say something like

/playbin0/abin/audiosink/audiosink-actual-sink-alsa.sink: caps = ...

too.
