Record and take picture issue

[Chiheb Djabri]

Hi

I am a Gstreamer newbie and I createrd a Python Gtk application and then I
created a gst pipeline for streaming from webcam. This work fine. I also
create another pipeline for recording and taking picture. I have the
following elements:


/-----jpegenc---

/                    \
ximagesrc--- ffmpegcolorspace ---
output-selector---/-------mp4mux---input-selector---filesink


The problem is that i can't link elements together (I am not really sure of
what I am doing). Here is my code:

    def __init_rec_pipeline(self):
        self.rec_pipeline = gst.Pipeline("rec-pipeline")
        bus = self.rec_pipeline.get_bus()
        bus.enable_sync_message_emission()
        bus.add_signal_watch()
        bus.connect("message", self.gst_bus_message)

        src = gst.element_factory_make("ximagesrc", "src")
        src.set_property("xid", self.window.xid)

        conv = gst.element_factory_make("ffmpegcolorspace",
"ffmpegcolorspace")
        self.inselect = gst.element_factory_make("input-selector",
"inselect")
        self.outselect = gst.element_factory_make("output-selector",
"outselect")
        jpegenc = gst.element_factory_make("jpegenc", "jpegenc")
        mp4mux = gst.element_factory_make("mp4mux", "mp4mux")
        sink = gst.element_factory_make("filesink", "sink")

        self.rec_pipeline.add(src, conv, self.outselect, mp4mux, jpegenc,
self.inselect, sink)
        src.link(conv)
        conv.link(self.outselect)

        self.opad_a = self.outselect.get_request_pad("src%d")
        self.opad_b = self.outselect.get_request_pad("src%d")

        jpegenc.add_pad(self.opad_a)
        mp4mux.add_pad(self.opad_b)

        self.inselect.link(sink)

        self.ipad_a = self.inselect.get_request_pad("src%d")
        self.ipad_b = self.inselect.get_request_pad("src%d")

        jpegenc.add_pad(self.ipad_a)
        mp4mux.add_pad(self.ipad_b)

The code fail at the last two lines because I can't obtain pads from
input-selector.
Any idea ?

Any help or suggestion is welcome.
Thanks in advance
