v4l2src plugin: can't add"always-copy=FALSE" in C pipe

Hi everybody,
I'm trying to implement this pipe in a C program:

gst-launch -v v4l2src always-copy=FALSE ! TIVidenc1 codecName=mpeg4enc engineName=encode contiguousInputFrame=TRUE ! rtpmp4vpay pt=96 ! udpsink host=<HOST IP ADDRESS> port=5000

but I can't add 2 options : "always-copy=FALSE" and "port=5000".
A part of my program is:

*******************************************************************************************************************
#include <gst/gst.h>
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <glib.h>

int main (int argc, char *argv[])
{
GstElement *pipeline, *source,*sink,*encoder,*payloader;
gst_init (&argc, &argv);
pipeline = gst_pipeline_new ("pipe");
source = gst_element_factory_make ("v4l2src", "video_source");
encoder = gst_element_factory_make ("TIVidenc1", "encoder_mpeg4");
payloader= gst_element_factory_make ("rtpmp4vpay", "payloader_mpeg4");
sink = gst_element_factory_make ("udpsink", "output");

g_object_set (G_OBJECT (encoder),
"codecName","mpeg4enc",
"engineName","encode",
NULL);

g_object_set (G_OBJECT (sink),
"host","192.168.100.229",
"port","5000",
NULL);

..........
After that I add all the plugins to the pipe and link them together...
The pipe works, it doesn't give me any error/warning,I can see the video in the receiving host, but the communication port isn't "5000" and I'm sure that the v4l2src's option "always-copy" isn't FALSE because the CPU consume is high (if this option is false the consume is less)
What are my errors?

Thank you.

Best regards.
Lorenzo

Re: v4l2src plugin: can't add"always-copy=FALSE" in C pipe

A precisation:
it gives me this warning:
GLib-GObject-WARNING **: value "TRUE" of type `gboolean' is invalid or out of range for property `always-copy' of type `gboolean'

It needs to be:

g_object_set (sink, "port", 5000, NULL);

and

g_object_set (sink, "always-copy", FALSE, NULL);

ie. 5000 and FALSE, not "5000" and "FALSE". You can see the type of the
property in gst-inspect.

Cheers
