Hallo all,

i hacking currently on cheese and noticed "one more" performance issue.
i use web cam with "sample spec: s16le 1ch 16000Hz", if i start
gstreamer pipe it will get "float32le 1ch 44100Hz". I do not see match
sense to upsample stream and than get bigger file size and cpu load.
Especially on netbooks it is painful. Do you have any ideas how to let
gstreamer check what source caps are an than use it?

Here is pipe what i use gst-launch-0.10 pulsesrc ! audioconvert !
vorbisenc quality=0.5 ! oggmux ! filesink location=output.ogg
