It can be - * downloaded for free (registration required, though) from - * www.etsi.org. - * - * The spu_decoder should handle the packet type BUF_SPU_DVB. - * - * BUF_SPU_DVBSUB packets without the flag BUF_FLAG_SPECIAL contain - * the payload of the PES packets carrying DVBSUB data. Since the - * payload can be broken up over several buf_element_t and the DVBSUB - * is PES oriented, the decoder_info[2] field (low 16 bits) is used to convey the - * packet boundaries to the decoder: - * - * + For the first buffer of a packet, buf->content points to the - * first byte of the PES payload. decoder_info[2] is set to the length of the - * payload. The decoder can use this value to determine when a - * complete PES packet has been collected. - * - * + For the following buffers of the PES packet, decoder_info[2] is 0. - * - * The decoder can either use this information to reconstruct the PES - * payload, or ignore it and implement a parser that handles the - * irregularites at the start and end of PES packets. - * - * In any case buf->pts is always set to the PTS of the PES packet. - * - * - * BUF_SPU_DVB with BUF_FLAG_SPECIAL set contains no payload, and is - * used to pass control information to the decoder. - * - * If decoder_info[1] == BUF_SPECIAL_SPU_DVB_DESCRIPTOR then - * decoder_info_ptr[2] either points to a spu_dvb_descriptor_t or is NULL. - * - * If it is 0, the user has disabled the subtitling, or has selected a - * channel that is not present in the stream. The decoder should - * remove any visible subtitling. - * - * If it is a pointer, the decoder should reset itself and start - * extracting the subtitle service identified by comp_page_id and - * aux_page_id in the spu_dvb_descriptor_t, (the composition and - * auxilliary page ids, respectively). - **/ - - -#ifdef HAVE_CONFIG_H -#include "config.h" -#endif - -#include <stdio.h> -#include <stdlib.h> -#include <fcntl.h> -#include <unistd.h> -#include <string.h> - -#define LOG_MODULE "demux_ts" -#define LOG_VERBOSE -/* -#define LOG -*/ - -#include <xine/xine_internal.h> -#include <xine/xineutils.h> -#include <xine/demux.h> - -//#define TS_PMT_LOG -//#define TS_PAT_LOG - -#ifndef EXPORTED -# define EXPORTED __attribute__((visibility("default"))) -#endif - -#ifndef BUF_SPU_HDMV -# define BUF_SPU_HDMV 0x04180000 -#endif - -/* - #define TS_LOG - #define TS_PMT_LOG - #define TS_PAT_LOG - - #define TS_READ_STATS // activates read statistics generation - #define TS_HEADER_LOG // prints out the Transport packet header. -*/ - -/* - * The maximum number of PIDs we are prepared to handle in a single program - * is the number that fits in a single-packet PMT. - */ -#define PKT_SIZE 188 -#define BODY_SIZE (188 - 4) -/* more PIDS are needed due "auto-detection". 40 spare media entries */ -#define MAX_PIDS ((BODY_SIZE - 1 - 13) / 4) + 40 -#define MAX_PMTS ((BODY_SIZE - 1 - 13) / 4) + 10 -#define SYNC_BYTE 0x47 - -#define MIN_SYNCS 3 -#define NPKT_PER_READ 96 // 96*188 = 94*192 - -#define BUF_SIZE (NPKT_PER_READ * (PKT_SIZE + 4)) - -#define MAX_PES_BUF_SIZE 2048 - -#define CORRUPT_PES_THRESHOLD 10 - -#define NULL_PID 0x1fff -#define INVALID_PID ((unsigned int)(-1)) -#define INVALID_PROGRAM ((unsigned int)(-1)) -#define INVALID_CC ((unsigned int)(-1)) - -#define PROG_STREAM_MAP 0xBC -#define PRIVATE_STREAM1 0xBD -#define PADDING_STREAM 0xBE -#define PRIVATE_STREAM2 0xBF -#define AUDIO_STREAM_S 0xC0 -#define AUDIO_STREAM_E 0xDF -#define VIDEO_STREAM_S 0xE0 -#define VIDEO_STREAM_E 0xEF -#define ECM_STREAM 0xF0 -#define EMM_STREAM 0xF1 -#define DSM_CC_STREAM 0xF2 -#define ISO13522_STREAM 0xF3 -#define PROG_STREAM_DIR 0xFF - - typedef enum - { - ISO_11172_VIDEO = 0x01, /* ISO/IEC 11172 Video */ - ISO_13818_VIDEO = 0x02, /* ISO/IEC 13818-2 Video */ - ISO_11172_AUDIO = 0x03, /* ISO/IEC 11172 Audio */ - ISO_13818_AUDIO = 0x04, /* ISO/IEC 13818-3 Audi */ - ISO_13818_PRIVATE = 0x05, /* ISO/IEC 13818-1 private sections */ - ISO_13818_PES_PRIVATE = 0x06, /* ISO/IEC 13818-1 PES packets containing private data */ - ISO_13522_MHEG = 0x07, /* ISO/IEC 13512 MHEG */ - ISO_13818_DSMCC = 0x08, /* ISO/IEC 13818-1 Annex A DSM CC */ - ISO_13818_TYPE_A = 0x0a, /* ISO/IEC 13818-6 Multiprotocol encapsulation */ - ISO_13818_TYPE_B = 0x0b, /* ISO/IEC 13818-6 DSM-CC U-N Messages */ - ISO_13818_TYPE_C = 0x0c, /* ISO/IEC 13818-6 Stream Descriptors */ - ISO_13818_TYPE_D = 0x0d, /* ISO/IEC 13818-6 Sections (any type, including private data) */ - ISO_13818_AUX = 0x0e, /* ISO/IEC 13818-1 auxiliary */ - ISO_13818_PART7_AUDIO = 0x0f, /* ISO/IEC 13818-7 Audio with ADTS transport sytax */ - ISO_14496_PART2_VIDEO = 0x10, /* ISO/IEC 14496-2 Visual (MPEG-4) */ - ISO_14496_PART3_AUDIO = 0x11, /* ISO/IEC 14496-3 Audio with LATM transport syntax */ - ISO_14496_PART10_VIDEO = 0x1b, /* ISO/IEC 14496-10 Video (MPEG-4 part 10/AVC, aka H.264) */ - STREAM_VIDEO_MPEG = 0x80, - STREAM_AUDIO_AC3 = 0x81, - STREAM_AUDIO_PRIMARY_DTS_HDMV = 0x86, - STREAM_SPU_BITMAP_HDMV = 0x90, - - STREAM_VIDEO_VC1 = 0xea, /* VC-1 */ - STREAM_VIDEO_SMTPE_VC1 = 0xeb, /* SMTPE VC-1 */ - } streamType; - -#define WRAP_THRESHOLD 270000 - -#define PTS_AUDIO 0 -#define PTS_VIDEO 1 - -#undef MIN -#define MIN(a,b) ((a)<(b)?(a):(b)) -#undef MAX -#define MAX(a,b) ((a)>(b)?(a):(b)) - -/* -** -** DATA STRUCTURES -** -*/ - -/* - * Describe a single elementary stream. - */ -typedef struct { - unsigned int pid; - fifo_buffer_t *fifo; - uint8_t *content; - uint32_t size; - uint32_t type; - int64_t pts; - buf_element_t *buf; - unsigned int counter; - uint16_t descriptor_tag; /* +0x100 for PES stream IDs (no available TS descriptor tag?) */ - int64_t packet_count; - int corrupted_pes; - uint32_t buffered_bytes; - int autodetected; - -} demux_ts_media; - -/* DVBSUB */ -#define MAX_SPU_LANGS 16 - -typedef struct { - spu_dvb_descriptor_t desc; - int pid; - int media_index; -} demux_ts_spu_lang; - -/* Audio Channels */ -#define MAX_AUDIO_TRACKS 16 - -typedef struct { - int pid; - int media_index; - char lang[4]; -} demux_ts_audio_track; - -typedef struct { - /* - * The first field must be the "base class" for the plugin!
