           Summary: mpegts: add support for ATSC tables MGT / ETT / EIT
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: thiagossantos at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


ATSC has the Master Guide Table that contains an association of PIDs to EITs
abd also ETTs (extended text table) tables, the ETTs contains internationalized
descriptions of the content in the virtual channels or for events.

The table id for ETT should be 0xCC and for EIT (in ATSC) should be 0xCB, the
MGT has the table id 0xC7 and is on pid 0x1FFB.

The proposed solution adds:
1) Add MGT/ETT parsing to mpegts
2) Add identification of EIT and ETT tables so they are properly identified by
mpegts lib and used in tsbase (tsparse/tsdemux) element
3) Add dumping of ETT table to ts-parse example
