I need help with "interleave"

[gontzal]

Hi to all. 

I would to ask you how can I traslate this gst-launch code to a pyhton 
or Vala or Genie code. 

gst-launch-0.10 interleave name=i ! audioconvert ! wavenc ! filesink 
location=file.wav \
filesrc location=file1.wav ! decodebin ! audioconvert ! 
"audio/x-raw-int,channels=1" ! queue ! i. \
  filesrc location=file2.wav ! decodebin ! audioconvert ! 
"audio/x-raw-int,channels=1" ! queue ! i.

I have tryied with this code without success.

uses Gst

pipeline: private Pipeline 
interleave: private Element
audioconvert: private Element
audioconvert2: private Element
audioconvert3: private Element
wavenc: private Element
decodebin2: private Element
decodebin3: private Element
capsfilter2: private Element
capsfilter3: private Element
filesink: private Element
src3:private Element
src2:private Element
queue2:private Element
queue3:private Element
capsfilter2a:private Element
capsfilter3a:private Element

init
    Gst.init (ref args);
    pipeline = new Pipeline ("mypipeline");

    interleave=ElementFactory.make ("interleave","inter")
    interleave.set ("name","i")
    audioconvert=ElementFactory.make ("audioconvert","audioconvert")
    wavenc=ElementFactory.make ("wavenc","wavenc")
    filesink=ElementFactory.make ("filesink","filesink")
    filesink.set("location","totalfinal.wav")

    // primer archivo
    src2= ElementFactory.make ("filesrc", "filesrc2")
    src2.set ("location","file1.wav")
    decodebin2= ElementFactory.make ("decodebin", "decodebin2")
    audioconvert2= ElementFactory.make ("audioconvert", "audioconvert2")
    capsfilter2= ElementFactory.make ("capsfilter","capsfileter2")
    capsfilter2.set("caps", 
Gst.Caps.from_string("audio/x-raw-int,channels=1"))
    queue2= ElementFactory.make ("queue","queue2")
    capsfilter2a= ElementFactory.make ("capsfilter","capsfileter2a")
    capsfilter2a.set("caps", Gst.Caps.from_string("i.sink_0"))

    // segundo archivo
    src3= ElementFactory.make ("filesrc", "filesrc3")
    src3.set ("location","file2.wav")
    decodebin3= ElementFactory.make ("decodebin", "decodebin3")
    audioconvert3= ElementFactory.make ("audioconvert", "audioconvert3")
    capsfilter3= ElementFactory.make ("capsfilter","capsfileter3")
    capsfilter3.set("caps", 
Gst.Caps.from_string("audio/x-raw-int,channels=1"))
    queue3= ElementFactory.make ("queue","queue3")
    capsfilter3a= ElementFactory.make ("capsfilter","capsfileter3a")
    capsfilter3a.set("caps", Gst.Caps.from_string("i.sink_1"))


    pipeline.add_many(interleave,wavenc,filesink,audioconvert);
    
pipeline.add_many(src2,src3,decodebin2,decodebin3,audioconvert2,audioconvert3,capsfilter2,capsfilter2a,capsfilter3,capsfilter3a);
    pipeline.add_many(queue2,queue3);

    // basic line
    interleave.link(audioconvert)
    audioconvert.link(wavenc)
    wavenc.link(filesink)

    // first src
    src2.link(decodebin2)
    decodebin2.link(audioconvert2)
    audioconvert2.link(capsfilter2)
    capsfilter2.link(queue2)
    queue2.link(capsfilter2a)

    // second src
    src3.link(decodebin3)
    decodebin3.link(audioconvert3)
    audioconvert3.link(capsfilter3)
    capsfilter3.link(queue3)
    queue3.link(capsfilter3a)


    pipeline.set_state(Gst.State.PLAYING)

    new MainLoop().run();

I have published the same question in stackoverflow. I you want you can 
answer there.
