How to set properties in GStreamer elements

[gstreader]

How to set the element's properties in C using g_object_set():

I would like to set the properties of x264enc element as

x264enc tune=zerolatency byte-stream=true bitrate=300   

I have used this code I am getting the warning:

g_object_set (videoenc, "tune","zerolatency","byte-stream",TRUE,"bitrate",300,NULL);

GLib-GObject-WARNING **: value "((GstX264EncTune) Zero latency (requires constant framerate) | 134519424)" of type `GstX264EncTune' is invalid or out of range for property `tune' of type `GstX264EncTune

  I would like to set the properties of  udpsink :

  I have used this code and getting warning:

 

  rtpsink = gst_element_factory_make ("udpsink", "rtpsink");

  g_assert (rtpsink);

  g_object_set (rtpsink, "port", 5000,"host", DEST_HOST, NULL);

  g_object_set(rtpsink,"ts-offset",VOFFSET,NULL);

  GLib-GObject-WARNING **: g_object_set_valist: object class `GstUDPSink' has no property named `127.0.0.1'

  Please some one reply me what I need to change that all work fine.

  Thanks in advance.

In x264enc the type of tune property is GstX264EncTune , but you are setting it as a string. So you need to pass an object of type GstX264EncTune.  

In udpsink make sure type of host property is a string, e.g. "127.0.0.1".   

All this information about which property is having which type can be checked by doing "gst-inspect <plugin_name>".
