DVB-SCAN.H(3)

💖 NAME 💖

okay so bestie, <pink>dvb-scan.h</pink> is literally the header that hands you the interfaces to scan programs inside MPEG-TS digital TV streams. no cap, that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

first things first, you gotta pull in the squad:

#include <stdint.h>
#include <linux/dvb/dmx.h>
#include <libdvbv5/descriptors.h>
#include <libdvbv5/dvb-sat.h>

🎀 Data Structures

• struct dvb_v5_descriptors_program — the matchmaker that associates PMT with PAT tables. it's giving wingman energy.
• struct dvb_v5_descriptors — contains the descriptors you need to scan the Service ID and all the other relevant info floating around in a MPEG-TS Digital TV stream. main character struct fr fr.
• struct dvb_table_filter — describes the PES filters that DVB scan uses. the bouncer at the club, checking who gets in. 💅

🌸 Macros

#define MAX_TABLE_SIZE

🦋 Typedefs

• typedef int check_frontend_t(void *args, struct dvb_v5_fe_parms *parms) — a callback for your app to show the frontend status. like a little check-in text, but for your frontend. 🫶

🔥 Functions

• void dvb_table_filter_free (struct dvb_table_filter *sect) — deallocates all data associated with a table filter. bye bestie, clean up after yourself. ✨
• int dvb_read_section (struct dvb_v5_fe_parms *parms, int dmx_fd, unsigned char tid, uint16_t pid, void **table, unsigned timeout) — read MPEG-TS tables that comes from a DTV card. the classic.
• int dvb_read_section_with_id (struct dvb_v5_fe_parms *parms, int dmx_fd, unsigned char tid, uint16_t pid, int ts_id, void **table, unsigned timeout) — same thing but with an specific table section ID. it's giving "I know exactly who I'm looking for". 👑
• int dvb_read_sections (struct dvb_v5_fe_parms *parms, int dmx_fd, struct dvb_table_filter *sect, unsigned timeout) — read MPEG-TS tables that comes from a DTV card (plural version, yes it's a different function, don't @ me, the source said so).
• struct dvb_v5_descriptors * dvb_scan_alloc_handler_table (uint32_t delivery_system) — allocates a struct dvb_v5_descriptors. new struct, who dis.
• void dvb_scan_free_handler_table (struct dvb_v5_descriptors *dvb_scan_handler) — frees a struct dvb_v5_descriptors. releasing it back to the universe. 🌈
• struct dvb_v5_descriptors * dvb_get_ts_tables (struct dvb_v5_fe_parms *parms, int dmx_fd, uint32_t delivery_system, unsigned other_nit, unsigned timeout_multiply) — scans a DVB stream, looking for the tables needed to identify the programs inside a MPEG-TS. the detective arc. 🔍
• void dvb_free_ts_tables (struct dvb_v5_descriptors *dvb_desc) — frees a struct dvb_v5_descriptors. yes, again. there's two of them. iconic.
• struct dvb_v5_descriptors * dvb_scan_transponder (struct dvb_v5_fe_parms *parms, struct dvb_entry *entry, int dmx_fd, check_frontend_t *check_frontend, void *args, unsigned other_nit, unsigned timeout_multiply) — scans a DVB dvb_add_scaned_transponder. going out into the wild to find transponders. 🦋
• void dvb_add_scaned_transponders (struct dvb_v5_fe_parms *parms, struct dvb_v5_descriptors *dvb_scan_handler, struct dvb_entry *first_entry, struct dvb_entry *entry) — add new transponders to a dvb_file. adding them to the group chat, essentially. 💌

aww okay that's the whole page bestie!! and before you go — the fine print at the bottom said this is libdvbv5, Version 1.32.0, and it's page lib/includ.../dvb-scan.h(3) in the Library Functions Manual. take care of her, she's iconic. 💖🎀🦋
