[gstreamer] initialization

■ Simple initialization

test.c

#include <stdio.h>
#include <gst/gst.h>

int
main (int   argc,
      char *argv[])
{
  const gchar *nano_str;
  guint major, minor, micro, nano;

  gst_init (&argc, &argv);

  gst_version (&major, &minor, &micro, &nano);

  if (nano == 1)
    nano_str = "(CVS)";
  else if (nano == 2)
    nano_str = "(Prerelease)";
  else
    nano_str = "";

  printf ("This program is linked against GStreamer %d.%d.%d %s
",
          major, minor, micro, nano_str);

  printf("macro version: %d.%d.%d
", GST_VERSION_MAJOR, GST_VERSION_MINOR, GST_VERSION_MICRO);
  return 0;
}

■ 编译

gcc test.c -o test `pkg-config --cflags --libs gstreamer-1.0`

■ 运行结果
