Mark Thompson 73ed6fa9d7 amfenc: Do not automatically download/upload unknown hardware input frames 
Supplying a hardware input frame which is not in the input hardware frames
context is not allowed by the API, so additional code to handle it is not
necessary.  Further, handling it automatically results in very low
performance - it is more appropriate to fail immediately so that the user
can fix their incorrect setup.

FFmpeg README

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

Libraries

  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of 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.
