       fame_register - register an object to the library


       #include <fame.h>

       void fame_register(fame_context_t *context, char const *type, fame_object_t *object);


       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


       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

       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


                fame_object_t *object;

                object = fame_get_object(fc, "profile/mpeg4/simple");
                if(object) fame_register(fc, "profile", object);

       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.

              int my_encode(fame_profile_t *profile, fame_yuv_t *yuv, unsigned char *shape)
                printf("Hello world!");

                  fame_profile_t *my_profile;

                  my_profile = FAME_PROFILE(fame_get_object(fc, "profile"));
                  my_profile->encode = my_encode;

       will  overide  the  default  profile  ’encode’  function  with this one
       printing "Hello world!" :)
