NAME
fame_register - register an object to the librarySYNOPSIS
#include <fame.h> void fame_register(fame_context_t *context, char const *type, fame_object_t *object);
DESCRIPTION
fame_register() is used to register an object to the library and associate a type with it. Upon initialisation with fame_init , libfame looks for the fame_profile_t object associated with the "profile" type and calls its 'init' function. Then this object may get other objects through fame_get_object , and so on. Thus, fame_register enables the use of objects from the application inside the library, and can be used to change or extend the default behaviour of the library.context is the context handle previously returned by fame_open
type is a type identifier to be associated with the object for further retrieval through fame_get_object.
object is the object to associate with type
BUILTIN OBJECTS
Currently the built-in objects and their default associations are:fame_profile_t* profile,profile/mpeg1
MPEG-1 profile, uses "syntax/mpeg1", "encoder/mpeg" and "motion"
fame_profile_t* profile/mpeg4,profile/mpeg4/simple
MPEG-4 simple profile, uses "syntax/mpeg4", "encoder/mpeg" and "motion"
fame_profile_t* profile/mpeg4/shape
MPEG-4 shape profile, uses "syntax/mpeg4", "encoder/mpeg", "shape" and "motion"
fame_syntax_t* syntax,syntax/mpeg1
MPEG-1 bitstream syntax
fame_syntax_t* syntax/mpeg4
MPEG-4 bitstream syntax
fame_encoder_t* encoder,encoder/mpeg
MPEG encoder
fame_motion_t* motion,motion/none
null motion estimation
fame_motion_t* motion,motion/fourstep
four step motion estimation
fame_motion_t* motion,motion/pmvfast
pmvfast motion estimation
fame_rate_t* rate
simple rate control
fame_shape_t* shape
shape coder
EXAMPLES
will try to get the object associated with "profile/mpeg4/simple" and register it for the "profile" type as well. This piece of code, called just after fame_open and just before fame_init would effectively have libfame produce MPEG-4 output instead of default MPEG-1.
will overide the default profile 'encode' function with this one printing "Hello world!" :)
