Failure X264 in gstreamer-1.10.4

[gagankumarnigam]

Hi All,

I am using gstreamer-1.10.4 on rhel-7.1 with
gst-plugins-good-1.10.4
gst-plugins-ugly-1.10.4
gstreamer1-libav-1.2.4-4.el7.x86_64
x264-libs-0.148-11.20160614gita5e06b9.el7.x86_64

and compiled the tutorial.c programme with this command

#include <gst/gst.h>
#include <glib.h>
#include <stdio.h>
#include <glib-object.h>

static gboolean bus_call (GstBus *bus, GstMessage *msg, gpointer data)

   return 0;
}

g++ tutorial1.c -o tutorial1 `pkg-config --cflags --libs gtk+-2.0
gstreamer-1.0 gstreamer-video-1.0`

it compiled successfully .But executing the ./tutorial1 fails on x264enc.
however, x264 is available on the path
/usr/lib64/lib/gstreamer-1.0/libgstx264.so and  which is linked witk
PKG_CONFIG_PATH

Can any body tell me what is the problem here??

Hi gagankumarnigam,

You've got a typo in the element name.

You want "x264enc" here.

HTH,
  Charlie.

Thanx Charlie for reply,

Previously i tried with x264enc and repeatedly facing the same problem of
crashing at the same point.
After some googling i came to know for gstreamer-1.10.4 x264 can also be
used in place of above one but still the condition is same.
however the same programme is working fine on Rhel-6.5 with
gstreamer-0.10.29.
Al Though, x264 is available on the path
/usr/lib64/lib/gstreamer-1.0/libgstx264.so and  which is linked with
PKG_CONFIG_PATH

but still.............

Any Clue Charlie ....
