I know I should use the fdsrc, but how to force a format afterwards? >From what I understood so far, I'll need: fdsrc fd=3 ! [XXX] ! audioconvert ! audioresample ! vader name=vad auto-threshold=true .... What goes in the [XXX] place? </blockquote><div> You need a capsfilter and set its "caps" property. In gst-launch, you can just put the caps under "" and it will work. Take a look at gst-inspect audioconvert and you'll see (at its pad templates) plenty of raw audio caps examples. </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Thanks for any help -- KTHXBYE, Stanisław Pitucha, Gradwell Voip Engineer ------------------------------------------------------------------------------ Come build with us!
