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. # Supported base MPEG-TS sections These are the sections for which parsing and packetizing code exists. ## Program Association Table (PAT) See: * gst_mpegts_section_get_pat() * gst_mpegts_pat_program_new() * %GstMpegtsPatProgram ## Conditional Access Table (CAT) See: * gst_mpegts_section_get_cat() ## Program Map Table (PMT) See: * %GstMpegtsPMT * gst_mpegts_section_get_pmt() * gst_mpegts_pmt_new() * %GstMpegtsPMTStream ## Transport Stream Description Table (TSDT) See: * gst_mpegts_section_get_tsdt() # API The type of section.
