Devin Heitmueller 19798229df avformat/mpegts: add support for preserving SMPTE 2038 when transcoding MPEG-TS streams 
Add the appropriate descriptors to the MPEG-TS demux and mux to
ensure that SMPTE 2038 VANC streams are properly preserved
when using codec copy (including adding the appropriate PMT
descriptors).

The focus of this patch is TS input to TS output.  A separate
patch adds support for output of 2038 VANC over decklink SDI.

Thanks to Marton Balint for feedback to preserve ABI compatibility.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
