# Mpeg TS helper library
|
||||
# MPEG-TS helper library
|
||||
|
||||
This library should be linked to by getting cflags and libs from
|
||||
gstreamer-plugins-bad-{{ gst_api_version.md }}.pc and adding
|
||||
-lgstmpegts-{{ gst_api_version.md }} to the library flags.
|
||||
|
||||
> NOTE: This library API is considered *unstable*
|
||||
|
||||
## Purpose
|
||||
|
||||
The MPEG-TS helper library provides a collection of definitions, object,
|
||||
enumerations and functions to assist with dealing with the base *MPEG 2
|
||||
Transport Stream* (MPEG-TS) format (as defined by `ISO/IEC 13818-1` and `ITU-T
|
||||
H.222.0`) and its derivates (`DVB`, `ATSC`, `SCTE`, `ARIB`, `Blu-ray`, `AVCHD`,
|
||||
...).
|
||||
|
||||
|
||||
This library provides helpers for dealing with:
|
||||
|
||||
* The various Section Information (SI) and Program-Specific Information (SI),
|
||||
handled with the [GstMpegtsSection](GstMpegtsSection) object and related
|
||||
functions.
|
||||
|
||||
* The various descriptors present in SI/PSI, handled with the
|
||||
[GstMpegtsDescriptor](GstMpegtsDescriptor) object and related functions.
|
||||
|
||||
|
||||
This library does not cover:
|
||||
|
||||
* Parsing MPEG-TS packets (PSI or PES) and extracting the sections. One can use
|
||||
an existing demuxer/parser element for this, or parse the packets
|
||||
themselves.
|
||||
|
||||
* Generate and multiplex MPEG-TS packets and sections. One can use an existing
|
||||
muxer element for this.
|
||||
|
||||
Applications, or external elements, can interact with the existing MPEG-TS
|
||||
elements via [messages](gst_message_new_mpegts_section) (to receive sections) or
|
||||
[events](gst_mpegts_section_send_event) (to send sections).
|
||||
|
||||
## Specification and References
|
||||
|
||||
As much as possible, the information contained in this library is based on the
|
||||
official Specification and/or References listed below:
|
||||
|
||||
### `MPEG-TS`
|
||||
|
||||
This is the base specification from which all variants are derived. It covers
|
||||
the basic sections (for program signalling) and descriptors. All variants must
|
||||
abide by this specification.
|
||||
|
||||
* `ISO/IEC 13818-1` and `ITU-T H.222.0`: *"Information technology – Generic
|
||||
coding of moving pictures and associated audio information: Systems"*. The two
|
||||
specifications are identical, the ITU one is more easily available (*nudge*).
|
||||
|
||||
### `SMPTE-RA` : *SMPTE Registration Authority*
|
||||
The official registration authority for MPEG-TS. This is used for the base
|
||||
[Registration Descriptor](gst_mpegts_descriptor_parse_registration) which
|
||||
allows to unambiguously identify a stream when it is not specified in a standard
|
||||
(yet).
|
||||
|
||||
* <http://smpte-ra.org/>
|
||||
|
||||
### `DVB` : *Digital Video Broadcasting*
|
||||
|
||||
This standards body covers the variant of MPEG-TS used in Europe, Oceania, and
|
||||
most of Asia and Africa. The standards are actually published by the `ETSI`
|
||||
(European Telecommunications Standards Institute).
|
||||
|
||||
* `ETSI EN 300 468`: *"Digital Video Broadcasting (DVB); Specification for
|
||||
Service Information (SI) in DVB systems"*. Covers all the sections and
|
||||
descriptors used in DVB variants.
|
||||
* `ETSI EN 101 154`: *"Digital Video Broadcasting (DVB);Specification for the
|
||||
use of Video and Audio Coding in Broadcast and Broadband
|
||||
Applications"*. Provides more details about signalling/sectios for audio/video
|
||||
codecs.
|
||||
|
||||
### `ATSC` : *Advanced Television Systems Committee*
|
||||
|
||||
This set of standards covers the variants of MPEG-TS used in North America.
|
||||
* `ATSC A/53-3` : *"ATSC Digital Television Standard, Part 3 – Service Multiplex
|
||||
and Transport Subsystem Characteristics"*. How ATSC extends the base MPEG-TS.
|
||||
* `ATSC A/65` : *"ATSC Standard:Program and System Information Protocol for
|
||||
Terrestrial Broadcast and Cable"*. Covers all sections and descriptors used in
|
||||
ATSC 1.0 variants.
|
||||
* `ATSC A/90` : *"ATSC Data Broadcast Standard"*. Extensions for data transfer
|
||||
(i.e. DSM-CC).
|
||||
* `ATSC A/107` : *"ATSC 2.0 Standard"*. Adds a few more descriptors.
|
||||
* `ATSC Code Points Registry` : The list of stream types, decriptor types,
|
||||
etc... used by ATSC standards.
|
||||
|
||||
### `SCTE` : *Society of Cable Telecommunications Engineers*
|
||||
|
||||
This set of standards evolved in parallel with ATSC in North-America. Most of it
|
||||
has been merged into ATSC and other standards since.
|
||||
|
||||
* `ANSI/SCTE 35` : *"Digital Program Insertion Cueing Message for Cable"*
|
||||
|
||||
### `DSM-CC` : "Digital Storage Media - Command & Control"
|
||||
|
||||
This ISO standard is the base for asynchronously carrying "files" over mpeg-ts.
|
||||
|
||||
* `ISO/IEC 13818-6` : *"Information technology — Generic coding of moving
|
||||
pictures and associated audio information — Part 6: Extensions for DSM-CC"*.

* ## Generic usage of sections with %GstMpegtsSection
|
||||
*
|
||||
* The %GstMpegtsSection object is the representation of MPEG-TS Section (SI or
|
||||
* PSI).
|
||||
*
|
||||
* Various elements can post those on the bus via %GstMessage of type
|
||||
* %GST_MESSAGE_ELEMENT. The gst_message_parse_mpegts_section() function
|
||||
* provides access to the section.
|
||||
*
|
||||
* Applications (or other elements) can create them either by using one of the
|
||||
* `gst_mpegts_section_from_*` functions, or by providing the raw SI data via
|
||||
* gst_mpegts_section_new().
|
||||
*
|
||||
* Elements outputting MPEG-TS streams can also create sections using the
|
||||
* various convenience functions and then get the packetized data (to be
|
||||
* inserted in MPEG-TS packets) using gst_mpegts_section_packetize().
|
||||
*
|
||||
* For more details, refer to the ITU H.222.0 or ISO/IEC 13818-1 specifications
|
||||
* and other specifications mentioned in the documentation.
