Using WASAPI in GStreamer

[orione1974]

I tried the component with:

gst-launch-0.10.exe -v wasapisrc ! filesink location="prv"

Setting pipeline to PAUSED ...
/GstPipeline:pipeline0/GstWasapiSrc:wasapisrc0.GstPad:src: caps =
audio/x-raw-int, width=(int)16, depth=(int)16, rate=(int)8000,
channels=(int)1, signed=(boolean)true, endianness=(int)1234
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstWasapiSrcClock
/GstPipeline:pipeline0/GstFileSink:filesink0.GstPad:sink: caps =
audio/x-raw-int, width=(int)16, depth=(int)16, rate=(int)8000,
channels=(int)1, signed=(boolean)true, endianness=(int)1234


But in the file "prv" I can see only "NULL" character (zero).

I tried "gst-launch-0.10 -v audiotestsrc ! wasapisink", but I get a error:

Setting pipeline to PAUSED ...

What's I'm wrong?
