Backends must implement the following function:
Importers are accessed by index i using values from 0 upwards. For out of range indexes, this function must return NULL.
No other symbols in a backend should be visible (ie. declare all other globals and functions as static).

#include <annodex/anx_types.h>
#include <annodex/anx_core.h>

Typedefs | |
typedef _AnxMediaImporter | AnxMediaImporter |
An AnxMediaImporter implements generic functions for retrieving data from sources of a particular content type. | |
typedef _AnxMediaTrack | AnxMediaTrack |
An AnxMediaTrack contains one track of data. | |
typedef _AnxMedia | AnxMedia |
An AnxMedia contains an instance of an active media object, which may in turn contain several tracks. | |
typedef AnxMedia *(* | AnxMediaOpenFunc )(const char *path, const char *id, int ignore_media, double start_time, double end_time, AnxImportCallbacks *import_callbacks) |
Signature of a function for opening a media object by filename. | |
typedef AnxMedia *(* | AnxMediaOpenFDFunc )(int fd, const char *id, int ignore_media, double start_time, double end_time, AnxImportCallbacks *import_callbacks) |
Signature of a function for opening a media object attached to an open file descriptor. | |
typedef long(* | AnxMediaReadFunc )(AnxMedia *media, unsigned char *buf, long n, long bound) |
Signature of a function for reading bytes from a media object. | |
typedef long(* | AnxMediaSizeofNextReadFunc )(AnxMedia *media, long bound) |
Signature of a function to return the preferred next read size. | |
typedef int(* | AnxMediaCloseFunc )(AnxMedia *media) |
Signature of a function to close a media object. | |
Functions | |
