void gst_util_set_value_from_string (GValue *value,
const gchar *value_str);Converts the string to the type of the value and sets the value with it.
| value : | the value to set |
| value_str : | the string to get the value from |
void gst_util_set_object_arg (GObject *object,
const gchar *name,
const gchar *value);Convertes the string value to the type of the objects argument and sets the argument with it.
| object : | the object to set the argument of |
| name : | the name of the argument to set |
| value : | the string value to set |
void gst_util_dump_mem (const guchar *mem,
guint size);Dumps the memory block into a hex representation. Useful for debugging.
| mem : | a pointer to the memory to dump |
| size : | the size of the memory block to dump |
void gst_print_pad_caps (GString *buf,
gint indent,
GstPad *pad);Write the pad capabilities in a human readable format into the given GString.
| buf : | the buffer to print the caps in |
| indent : | initial indentation |
| pad : | the pad to print the caps from |
void gst_print_element_args (GString *buf,
gint indent,
GstElement *element);Print the element argument in a human readable format in the given GString.
| buf : | the buffer to print the args in |
| indent : | initial indentation |
| element : | the element to print the args of |
