lib/include/libdvbv5/descriptors.h — Provides a way to handle MPEG-TS descriptors found on Digital TV streams.

Synopsis

#include <unistd.h>
#include <stdint.h>
#include <arpa/inet.h>

Data Structures

struct dvb_desc
Linked list containing the several descriptors found on a MPEG-TS table.
struct dvb_descriptor
Contains the parser information for the MPEG-TS parser code.

Macros

#define DVB_MAX_PAYLOAD_PACKET_SIZE
Maximum size of a table session to be parsed.
#define DVB_CRC_SIZE
number of bytes for the descriptor's CRC check

Typedefs

typedef void(* dvb_table_init_func) (struct dvb_v5_fe_parms *parms, const uint8_t *buf, ssize_t buflen, void **table)
Function prototype for a function that initializes the descriptors parsing on a table.
typedef int(* dvb_desc_init_func) (struct dvb_v5_fe_parms *parms, const uint8_t *buf, struct dvb_desc *desc)
Function prototype for the descriptors parsing init code.
typedef void(* dvb_desc_print_func) (struct dvb_v5_fe_parms *parms, const struct dvb_desc *desc)
Function prototype for the descriptors parsing print code.
typedef void(* dvb_desc_free_func) (struct dvb_desc *desc)
Function prototype for the descriptors memory free code.
