Devin Heitmueller ac4247270c avdevice/decklink_enc: add support for SMPTE 2038 VANC packet output 
Support decoding and embedding VANC packets delivered via SMPTE 2038
into the SDI output.  We leverage an intermediate queue because
data packets are announced separately from video but we need to embed
the data into the video frame when it is output.

Note that this patch has some additional abstraction for data
streams in general as opposed to just SMPTE 2038 packets.  This is
because subsequent patches will introduce support for other
data codecs.

Thanks to Marton Balint for review/feedback.

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.
